A study of lateral partner hiring by large U.S. law firms.

Abstract

Prior research demonstrates product market advantages of organizational status but largely neglects factor

market advantages. We propose that status is advantageous in labor markets because individuals generally

consider employer status a non-pecuniary employment benefit. Dyadic analyses of lateral partner hiring by

large U.S. law firms demonstrate two status-based advantages in employee hiring and retention. First, high

status firms are more likely than low status ones to hire an employee from a more profitable competitor.

Second, high status firms are most likely to lose an employee to a lower status competitor when the

competitor is – atypically – more profitable. We discuss implications of these findings for individual and

organizational status attainment and for the stability of industry status hierarchies.

Fundamental to the status-based model of market competition is the notion that organizational

status is a basis for product market advantage (Podolny, 1993; 2005). When product or service quality is

difficult to verify ex ante – frequently for cultural goods (Benjamin and Podolny, 1999; Bielby and

Bielby, 1999) or professional services (Podolny, 1993; 1994; 2001; Chung, Singh, and Lee, 2000; Jensen,

2006; Jensen and Roy, 2008; Uzzi and Lancaster, 2004) – market actors generally infer quality from the

status of the organization offering it for sale. Consequently, relative to low status competitors, high status

organizations enjoy lower marketing costs, higher prices, and greater sales, resulting in a typically

positive correlation between organizational status and profitability (Podolny, 1993; Podolny, Stuart, and

Hannan, 1996; Benjamin and Podolny, 1999; Podolny and Scott-Morton, 1999).

Prior research does not similarly establish status-based advantages in factor markets, despite

interest in such advantages. Most prominently, Podolny (2001: 43) speculates that hiring and retention

costs for equivalent labor are decreasing with status because individuals generally view high employer

status as a non-pecuniary employment benefit. Low status organizations are, consequently, constrained to

hiring from highly uncertain market segments (i.e., inexperienced candidates). Recently, Bidwell, et al.

(2013) argue that, relative to low status competitors, high status employers can hire more capable junior

employees at equivalent cost because individuals expect future career opportunities to be increasing with

employer status. But, despite extensive recent research on hiring competitors’ employees (e.g., Rao and

Drazin, 2002; Broschak, 2004; Wezel, Cattani, and Pennings, 2006; Groysberg, Nanda, and Lee, 2008;

Dokko and Rosenkopf, 2010), the advantages of status in labor markets remain largely speculative.

In this study, we examine whether or not organizational status aids in employee hiring or

retention. We draw on the economic concept of equalizing differences (Rosen, 1986), which suggests

that individuals trade-off pecuniary and non-pecuniary benefits in employment alternatives (e.g., Stern,

2004). We specifically consider how, by providing a basis for non-pecuniary benefits, organizational

status aids in hiring competitors’ employees and in retaining employees valued by competitors.

Assumptions of individual and organizational preferences inform baseline predictions about which

organizations within an industry are most likely to hire each other’s employees. We theorize a central

tendency of organizations to hire employees from competitors of similar status and profitability. But, we

also argue that deviations from these tendencies entail individual trade-offs between pecuniary and non-

pecuniary employment benefits that favor high status organizations over lower status ones.

We situate our inquiry in U.S. legal services, an industry characterized by increased hiring from

competitors over the past decade (see Figure 1). Specifically, we analyze data on thousands of lateral

partner hires among the largest U.S. law firms between 2000 and 2009. We find that organizations do

tend to hire employees from competitors of similar status and profitability, but two labor market

advantages of organizational status are clear. First, high status firms are more likely to hire a partner from

a more profitable competitor than are low status firms. Second, high status firms are most likely to lose a

partner to a lower status competitor when the competitor is atypically profitable, given its status. Extant

theory suggests that the hiring advantage enhances profitability and that the retention advantage maintains

status. We attribute both advantages to employer status as a valuable non-pecuniary employment benefit.

We discuss the implications of our study for intraprofessional status mobility (i.e., individual

transitions to employers of different status), for our understanding of the commonly observed positive

correlation between organizational profitability and organizational status, and for the stability of industry

status hierarchies. These considerations motivate a research agenda on organizational status attainment

that parallels the extensive literature on individual status attainment (see Lin, 1999 for a review).

Theoretical Development

The status-based model of market competition introduced the idea that organizational status

signals product or service quality in markets where quality is either difficult or costly for consumers to

verify ex ante (Podolny, 1993). Ex ante, consumers generally expect offering quality to be increasing

with producer status. Ex post, high status producers also receive greater recognition and rewards for work

of equivalent quality than low status actors receive because status enhances visibility and positively biases

the allocation of credit (Merton, 1968). In the context of market competition, these tendencies imply that

while nothing in principle prevents low status organizations from investing in high quality, high status

organizations realize greater returns on such investments (Podolny, 1993; Benjamin and Podolny, 1999).

High status producers consequently realize higher prices for offerings of equivalent quality.

These effects are especially pronounced in professional services, such as investment banking (Podolny,

1993; 1994; 2001; Chung, et al., 2000), accounting (Jensen, 2006; Jensen and Roy, 2008), and corporate

law (Uzzi and Lancaster, 2004) as well as in markets for cultural goods in which quality is also difficult to

verify ex ante. For example, wine of equal quality tends to be priced higher for high status producers than

for low status ones (Benjamin and Podolny, 1999). Furthermore, wineries that hire winemakers from

prominent competitors command higher prices, post-hire, for wines of a given quality – even wines made

by prior winemakers (Roberts, Khaire, and Rider, 2011).

The advantages of status are not limited to revenue. High status organizations also incur lower

costs of marketing equivalent quality offerings because exchange partners are more willing to enter

exchange relationships the greater the organization’s status is (Podolny, 1993). For example, low status

venture capital firms must offer startups better financing terms than high status competitors in order to

secure equity investments (Hsu, 2004). Both revenue and cost advantages are, therefore, implicated in the

widely-observed positive correlation between organizational profitability and status (see Podolny, 2005).

Given these product market advantages of status, profit-seeking organizations often invest

resources in attaining higher status and in maintaining status, primarily by adopting principles of

exclusivity in inter-organizational relations (Goode, 1978; Podolny, 1993). Generally, affiliating with

lower status organizations diminishes organizational status while affiliating with higher status ones

enhances status (Podolny and Phillips, 1996). For example, status-anxious organizations quickly

disassociated themselves from discredited auditor Arthur Andersen following the Enron scandal (Jensen,

2006) and wineries were more likely to publicize a winemaker’s prior employer the greater the prior

employer’s status (Roberts and Khaire, 2009).

Labor markets enable profit-seeking organizations to strategically invest in status. First,

individual transitions between employers transfer status by implicitly affiliating one’s current and prior

employers (Baty, et al., 1971; Sørensen, 1999). Second, especially when quality is difficult to assess ex

ante, employees’ prior employment affiliations are effective product market signals of organizational

quality (Burton, Sorensen, and Beckman, 2002; Higgins and Gulati, 2003; 2006). Third, organizations

often transfer status by hiring competitors’ employees (Rao and Drazin, 2002; Wezel, et al., 2006;

Somaya, Williamson, and Lorinkova, 2008; Dokko and Rosenkopf, 2010; Bidwell and Briscoe, 2010).

If organizations hire employees to enhance status and profitability, then high status organizations

may be particularly vulnerable to losing employees to competitors but also likely to hire employees from

competitors. Below, we accordingly consider how status and profitability differentials between

organizations influence the baseline likelihood that one organization hires an employee from another one.

We then consider how organizational status aids in the hiring and retention of employees.

Status differentials and the likelihood of hiring. We first make explicit assumptions about

individual and organizational preferences. First, affiliating with higher status organizations generally

enhances organizational status (Podolny and Phillips, 1996) and attracts exchange partners (Burton, et al.,

2002). More specifically, prior research demonstrates that hiring individuals previously employed by

high status employers enhances market actors’ evaluations of the hiring organization. For example,

biotech executives’ prior employment affiliations to high status organizations appeal to investors and,

consequently, underwriters (Higgins and Gulati, 2003; 2006). Another study found that hiring

winemakers from prominent competitors enabled wineries to command higher prices (Roberts, et al.,

2011). Based on such findings, we assume that, all else equal, organizations prefer to hire individuals

from higher status competitors than from lower status ones.

Second, the individual desire for greater social standing is generally considered universal (Frank,

1985; Hogan and Hogan, 1991). With respect to employment, individuals typically aspire to greater

intraprofessional status and, therefore, seek work with high status organizations (Abbott, 1981; Elsbach

and Glynn, 1996; Heinz, et al., 2005). The benefits of working for a high status employer are not merely

psychological. Because socioeconomic rewards are also allocated in ways that favor employees of high

status organizations (Merton, 1968), individuals can also expect that future career opportunities are

enhanced by employer status (Phillips, 2001; Bidwell, et al., 2013). All else equal, then, employer status

is a valuable non-pecuniary employment benefit; individuals generally prefer to work for organizations

that are higher in status than their current employers.

These assumptions imply that, with respect to organizational status, a focal organization’s

willingness to hire an individual is generally increasing as an individual’s willingness to work for the

organization is decreasing. We expect that these countervailing preferences will tend to restrict inter-

organizational hiring to organizations of similar status because individuals generally like their status-

conferring actions to be reciprocated (Gould, 2002) and because unsuccessful hiring attempts are costly

for organizations. We, therefore, expect that the higher or lower a competitor is in status than an

organization, the less likely the competitor is to hire an employee from that organization.

Hypothesis 1: An organization is less likely to hire an employee from a competitor the greater is

the difference in status between the organization and the competitor.

Profitability differentials and the likelihood of hiring. The status differential prediction is

motivated by differences in the non-pecuniary benefit of employer status. Differences in pecuniary

benefits are, of course, also relevant. All else equal, more profitable organizations can afford to allocate

greater financial resources to pecuniary benefits than less profitable organizations can.1 For example,

empirical studies tend to find that employee compensation is increasing with employer profitability (e.g.,

Deckop, 1988; Gerhart and Milkovich, 1990; Abowd, Kramarz, and Margolis, 1999). We, therefore,

assume that pecuniary benefits are increasing with organizational profitability so that individuals

generally prefer working for organizations that are more profitable than their current employers.

Organizations, however, typically prefer hiring from more profitable competitors than from less

profitable ones because, on average, employee productivity is presumably increasing with employer

1 Of course, organizations may increase profits by allocating smaller amounts of producer surplus to employees’

wages. Our point is merely that more profitable organizations are in better positions to raise employee wages than

less profitable organizations are.

profitability (Sørensen and Sorenson, 2007). As in the case of status differentials, countervailing

preferences of organizations and individuals will tend to constrain lateral hiring to organizations of

similar profitability. We, therefore, expect that the higher or lower a competitor is in profitability than an

organization, the less likely the organization is to hire an employee from that competitor.

Hypothesis 2: An organization is less likely to hire an employee from a competitor the greater is

the difference in profitability between the organization and the competitor.

Two status-based, labor market advantages are implied by Hypotheses 1 and 2. First, few

competitors of high status organizations are able to offer a superior non-pecuniary benefit (i.e., employer

status). Second, if profitability and status are indeed positively correlated then few competitors of high

status organizations are profitable enough to offer superior pecuniary benefits (i.e., compensation).

Consequently, we expect that organizational status aids in hiring employees from competitors and also in

retaining employees who competitors wish to hire. We consider these implications below.

Status advantages in hiring. We first consider how organizational status facilitates the hiring of

competitors’ employees. Employee recruitment is central to an organization’s competitive advantage. As

prior work demonstrates, hiring is an effective strategy for acquiring knowledge (e.g., Almeida and

Kogut, 1999), business relationships (e.g., Somaya, et al., 2008; Dokko and Rosenkopf, 2010), and

capabilities (e.g., Rao and Drazin, 2002). Yet, hiring advantages based on organizational status have

gone largely unexplored in prior research.

We assume that organizations prefer hiring employees from more profitable competitors than

from less profitable ones because of presumed employee productivity differences that vary systematically

with organizational profitability (Sørensen and Sorenson, 2007). The theory of equalizing differences

implies that individuals considering a move to a less profitable employer will probably expect greater

non-pecuniary benefits (Rosen, 1986; Fersthman and Weiss, 1993; Stern, 2004). In such cases, non-

pecuniary benefits associated with employer status probably help high status organizations hire a more

profitable competitor’s employee. As Coleman (1990: 130) observes, ‘‘…the awarding of status to

balance unequal transactions or to make possible half-transactions appears to be the most widespread

Page 9: Labor market advantages of organizational status: A study ...€¦ · large U.S. law firms demonstrate two status-based advantages in employee hiring and retention. First, high status

functional substitute for money in social and political systems.’’ Consequently, we expect that a high

status organization is more likely to hire an employee from a more profitable competitor than a low status

organization is. Such hires are, presumably, profitability-enhancing.

Hypothesis 3: An organization is more likely to hire an employee from a more profitable

competitor if it is higher in status than if it is lower in status than the competitor.

Status advantages in retention. We now consider how status helps organizations retain employees

valued by competitors. Employee retention is critical for sustaining an organization’s competitive

advantage (e.g., Coff, 1997), as prior work demonstrates that employee departures can lead to the

dissolution of business relationships (e.g., Broschak, 2004) or entire organizations (e.g., Phillips, 2001;

Wezel, et al., 2006). Yet, status-based retention advantages have also been neglected in prior work.

We previously assumed that high status organizations’ employees are valued by competitors

because high status affiliations enhance organizational status (Podolny and Phillips, 1996; Jensen, 2006).

Low status competitors may seek to invest in status by hiring a higher status organization’s employees.

Such hires are, presumably, status-enhancing for the hiring competitor and status-diminishing for the

organization (e.g., Podolny and Phillips, 1996). How can a low status competitor facilitate such moves?

Again, the theory of equalizing differences implies that individuals considering a move to a lower

status employer will expect to be compensated for a reduction in employer status with greater pecuniary

benefits. Therefore, a competitor trying to hire an employee away from a higher status organization must

offer greater pecuniary benefits than the employee’s current employer provides. If profitability enables

organizations to make such attractive offers, then high status organizations are most at risk of losing

employees to their more profitable competitors.

Recruiting a less profitable competitor’s employees may seem a profit-diminishing strategy. But,

in the long run, such status investments could plausibly increase organization profitability by enhancing

organizational status and diminishing competitor status, thereby reducing the higher status organization’s

product market advantage. Low status organizations should, therefore, be particularly motivated to hire

employees away from high status ones. For example, although low status universities incur greater costs

8

of employing equivalent quality faculty than high status universities enhanced institutional status may

justify incurring higher costs (Meyer and Rowan, 1977; Podolny, 2001).

If status enables organizations to offer greater non-pecuniary benefits than lower-status-but-more-

profitable competitors offer, then low status organizations have weaker bargaining power with a given job

candidate than high status competitors do (Podolny, 2001; Phillips, 2001; Bidwell, et al., 2013). We

consequently expect that a high status organization is more likely to lose an employee to a lower status

competitor when the competitor is also more profitable than the high status organization. This reasoning

implies that high status organizations are most vulnerable to losing employees to competitors that are

atypically profitable, given their status (i.e., hierarchical anomalies).

Hypothesis 4: An organization is more likely to lose an employee to a lower status competitor if

the competitor is more profitable than if the competitor is less profitable than the organization.

To recap, we propose that despite individual and organizational preferences to the contrary, most

inter-organizational employment transitions are between organizations of similar status and profitability.

We also argue that by enabling organizations to offer employment with superior non-pecuniary

employment benefits, status provides two labor market advantages over competitors. First, status aids in

hiring employees of more profitable competitors. Second, although greater profitability helps

organizations hire employees from higher status competitors, the second labor market advantage of status

is that status helps organizations retain employees recruited by more profitable but lower status

competitors. Below, we outline empirical tests of these arguments.

Empirical Setting and Analysis

The context for testing these predictions is the U.S. legal services industry. We analyze hiring

events involving partners employed by the 200 highest-grossing law firms in the U.S. between 2000 and

2009 (i.e., the AM Law 200). These large, corporate-oriented, U.S. law firms are typically organized as

partnerships in which firm partners generate business, share profits, and supervise associate lawyers. Firm

status and profitability are particularly relevant for hiring because lawyers are particularly status-

conscious and many face large debt obligations (Phillips and Zuckerman, 2001; Sauder, 2008).

Furthermore, firm status is regularly assessed by industry surveys and so, too, is firm profitability.

Traditionally, law firms followed the “Cravath model” by growing internally, promoting

associates, developing partners, and fostering client relationships (Galanter and Palay, 1991). Associates

were promoted if partners felt that they would successfully transition from technical legal work to partner

responsibilities. The typical law school graduate joined a major law firm and hoped to become a partner

after six to eight years. Those who did would typically stay with the firm for the remainder of their

professional careers; those who did not would depart. Rarely would lawyers be hired into a partnership

from outside of the firm or dismissed after promotion to partner (Heinz, 2009).

Hiring competitors’ partners has long been a law firm growth strategy (e.g., McEvily, Jaffee, and

Tortoriello, 2012). But, until recently, such lateral hires were considered counter-normative because

lateral hiring appropriates a competitor’s investments in employees (Hillman, 2002). This norm eroded as

firm scale and competition increased and the costs of adhering to the Cravath Model’s “up or out” rule

grew larger (Sherer and Lee, 2002). Over the past decade, lateral hiring has increasingly become an

effective strategy for enhancing firm growth and performance because the work that partners perform

does not fundamentally vary across employers, but prices do vary (Uzzi and Lancaster, 2004).

Figure 1 illustrates the trend in lateral partner hiring from 2000 to 2009. In 2000, 64 percent of

partner hires by AM Law 200 firms were from an employer outside of the AM Law 200, such as in-house

corporate legal departments, government, or smaller firms. By 2009, however, the modal partner

transition was from one AM Law 200 firm to another (i.e., 59 percent of all partner hires).

Firm motivations for hiring laterally vary but can generally be characterized as status-seeking and

profit-seeking. An industry search consultant remarked in 2013, “…reasons number one, two, and three

are to buy business” (Li, 2013). One firm chairman justified hiring a partner from a more prestigious

competitor as a way to “make a mark” in the industry (Koppel, 2007). In 2006, an industry observer

described lateral hiring as “skim[ming] the cream of partners from less profitable firms” (Triedman,

2006). As for individuals, a survey of over 900 partners who moved laterally indicated that 90 percent

Page 12: Labor market advantages of organizational status: A study ...€¦ · large U.S. law firms demonstrate two status-based advantages in employee hiring and retention. First, high status

10

either maintained or increased their compensation but also that partners who did not move were similarly

satisfied with their compensation (Major, Lindsey, and Africa, 2012). These results imply that partners

probably view pecuniary and non-pecuniary employment benefits as compensatory. Moreover, our

assumption of a positive correlation between firm profitability and compensation is appropriate for this

setting because firm partners are typically residual claimants on firm profits (Galanter and Palay, 1991).

In sum, lateral hiring by large U.S. law firms is an excellent setting for identifying status-based labor

market advantages.

Dependent variable. We test predictions about an organization’s likelihood of hiring from a

competitor as well as its likelihood of losing an employee to a competitor. The main dependent variable in

our analysis is the likelihood that an AM Law 200 firm i hires a partner from another AM Law 200 firm j

in a given year (we use “firm i” and “firm j” throughout to denote the hiring and source organizations,

respectively, in a dyad at-risk of a lateral hire). Data on lateral hiring were obtained from Incisive Legal

Intelligence’s Lateral Partner Moves Database, which summarizes hiring information from The American

Lawyer’s annual Lateral Partner Survey of AM Law 200 firms, industry publications, firm websites, and

press releases. Between 2000 and 2009, 9,465 partners transitioned between two AM Law 200 firms.

Sample and estimation. Our unit of analysis is a dyad in which a given firm i is at risk of hiring

a partner from firm j. Our dyadic sample covers 178 unique firms and 5,270 lateral partner hires over an

8-year period from 2002 to 2009. These figures are lesser than the 200 AM Law ranked firms and the

total 9,465 lateral partner hires because we restrict the analyzed sub-sample to include lagged variables

and because firm status measures are unavailable for the lowest status firms in the AM Law 200. This

produces 162,696 dyadic, firm-firm observations; hiring occurs in 3,473 of these dyads (2.1 percent).2 For

dyads in which hiring does occur (5,270 hires from 3,473 dyads), the median and modal number of

2 We exclude 25,108 dyads to include lagged dependent variables, 39,336 dyads due to missing geographic data, and

170,860 observations due to missing status data. Restricting the sample to 178 firms effectively limits our analyses

to dyads within the upper three quartiles of the status distribution for AM Law 200 firms. Gross revenue is

positively but imperfectly correlated with status, so our analyses are most representative of the highest status 110 to

160 U.S. law firms in any year.

partners hired in a year is one and in 95 percent of cases three or fewer partners are hired within the year.

Table 1 summarizes annual counts of firms, dyads, and lateral hires for our sample.

Logit estimates are biased when the unconditional probability of a binary event is low. So, we

correct coefficient estimates and standard errors to account for the systematic bias attributable to the

dependent variable’s low unconditional mean. Using a rare-events logit specification, we model the

likelihood of firm i hiring a partner from firm j in year t (King and Zeng, 2001). To account for non-

independence of observations attributable to the same dyads appearing multiple times in our sample, we

also cluster errors by dyad. Alternatively, clustering errors by hiring firm, by source firm, or

simultaneously by hiring firm and source firm yields results consistent with those we report.

Independent variables. The key independent variables are status and profitability differentials

between hiring firm i and source firm j. Our status measure is each firm’s prestige score from Vault.com’s

annual law firm rankings. Annually, Vault identifies the 100 most prestigious law firms in the U.S. based

on interviews with lawyers, industry news, prior rankings of law firms, and surveys of thousands of

associates working at these firms. Thousands of associates rate firms, on a scale of 1 to 10, based on how

prestigious they believe working for each firm would be. Respondents do not rate their own firms and are

asked not to rate firms with which they are not familiar. Rankings are based on each firm’s average rating

in these surveys. These scores measure each firm’s generalized labor market status and fit well with

sociological conceptualizations of status as an aggregate of peer attributions (Gould, 2002).

The number of firms included in the top 100 actually varies from year to year and approximately

half of all AM Law 200 firms do not make Vault’s top 100 each year. Rather than restrict our analysis to

only the most prestigious 100 law firms in each year, we obtained prestige scores directly from Vault for

all firms identified in Vault’s survey exercise – including unranked firms. Firm counts range from 126

firms in 2002 to 166 firms in 2010. This data limitation places an upper bound on the number of firms

that can be included in the dyads we analyze; excluded firms may be considered less prestigious than all

Page 14: Labor market advantages of organizational status: A study ...€¦ · large U.S. law firms demonstrate two status-based advantages in employee hiring and retention. First, high status

12

other firms included in that year. Given the positive empirical correlation between firm prestige and

profitability (0.76), this sampling restriction restricts variance within our sample and renders it less likely

that our analyses identify status or profitability differential effects than if we analyzed all AM Law 200

firms. In robustness checks, we observe similar results when including unrated firms in the analyzed

sample and assigning categorical status ranks over five status tiers instead of continuous status scores.

To estimate the effects of status differentials on the hiring likelihood, we compute status

differential between firm i and firm j as the absolute value of the difference between the Vault prestige

scores for i and j in that year. We also partition this variable into two separate variables based on whether

hiring the hiring firm i or source firm j is higher in status. The variable |Status differentialij|, Si > Sj is the

absolute value of the prestige score difference between hiring firm i and source firm j when the hiring

firm is of higher status. The variable |Status differentialij|, Si < Sj is the absolute value of the status

difference between i and j when the hiring firm is of lower status. Hypothesis 1 predicts negative

coefficients on both of these variables; the coefficient magnitudes indicate whether or not status

differentials exert different influences on the likelihoods of hiring from higher or lower status firms.

Profitability differential is based on profits-per-equity-partner (PPEP), or total firm profits

divided by the number of firm partners with residual claims, a common industry profitability metric that

is obtained from American Lawyer surveys. All else equal, we assume that a partner’s compensation is,

on average, increasing with their firm’s PPEP. We first compute the absolute value of the difference in

PPEP (in U.S. dollars) between hiring firm i and source firm j and then partition this variable into two

separate variables based on whether the hiring firm is more profitable. The variable |Profitability

differentialij|, Pi > Pj is the absolute value of the dollar profitability difference between hiring firm i and

source firm j when the hiring firm is more profitable. The variable |Profitability differentialij|, Pi < Pj is the

absolute value of the dollar profitability difference between hiring firm i and source firm j when the hiring

firm is less profitable. Hypothesis 2 predicts negative coefficients on both of these variables; the

coefficient magnitudes indicate whether or not profitability differentials exert different influences on the

likelihoods of hiring from higher or lower status firms.

To test Hypothesis 3 and Hypothesis 4, we create a set of variables indicating the relative status

and profitability of two firms at risk of hiring from one another. One variable identifies dyads in which

the hiring firm i is lower in status but more profitable than the source firm j (Si<Sj and Pi>Pj). A second

variable identifies dyads in which the hiring firm i is higher in status but less profitable than the source

firm j (Si>Sj and Pi<Pj). A third variable identifies dyads in which the hiring firm i is lower in status and

less profitable than the source firm j (Si<Sj and Pi<Pj). The omitted indicator identifies dyads in which

the hiring firm i is higher status and more profitable than the source firm j. To check that our predictions

are insensitive to differential magnitudes, we also test Hypotheses 3 and 4 using continuous measures.

Control variables. Dyad-level covariates account for factors other than relative status and

profitability that may affect the baseline likelihood of lateral hiring. The number of employment

opportunities a firm offers and the number of times a firm’s employees are hired by competitors are both

functions of employee headcount. Firms of different sizes are also likely to differ in terms of the legal

work they perform and the clients they serve (Heinz, et al., 2001). To account for baseline propensities of

individuals to transition from one firm to another, we compute size differential as the absolute value of

the difference in total number of lawyers (in 100s) employed by hiring firm i and source firm j.

Two variables account for major organizational events that influence both the labor market

supply of a firm’s partners and the firm’s demand for competitors’ partners. Dissolved is an indicator

variable that equals 1 when either hiring firm i or source firm j dissolves in a given year and 0 otherwise.

Lawyers employed by firms that dissolve are more likely to be hired by other firms than lawyers whose

firms survive the entire year and firms about to dissolve probably curtail hiring to survive. Merged is an

indicator variable taking a value of 1 when either the hiring firm i or source firm j merges with another

firm in a given year and 0 otherwise. A merger may indicate either future firm growth plans or,

conversely, the culmination of a firm growth plan; both influence the likelihood of lateral hiring.

Geographic distance influences search costs for potential employers and candidates and

adjustment costs imposed by changing employers. We first compute the spherical distances between each

of firm i’s offices and each of firm j’s offices based on their respective longitudes and latitudes (Sorenson

Page 16: Labor market advantages of organizational status: A study ...€¦ · large U.S. law firms demonstrate two status-based advantages in employee hiring and retention. First, high status

14

and Audia, 2000). Using data on firm-office headcount obtained from the National Law Journal’s annual

survey of the 250 largest U.S. law firms, we weight each distance by the product of the numbers of

lawyers in the two offices, take the sum of all weighted distances, and divide this by the product of the

total number of lawyers in the two offices. The resulting mean geographic distance variable is a

headcount-weighted measure of the average geographic distance, in hundreds of miles, between a

randomly chosen firm i lawyer and a randomly chosen firm j lawyer.

The variable Si > Sj takes a value of 1 when hiring firm i is higher in status and 0 when the source

firm j is higher in status. This variable accounts for baseline tendencies of partners to move from lower-

status to higher-status firms. Partitioning the status differential variable based on whether firm i is higher

or lower status is equivalent to specifying an interaction term between the status differential and this

indicator variable. Hence, this indicator must be included in all models that partition status differential in

order to obtain accurate coefficient estimates. Similarly, Pi > Pj is an indicator variable that takes a value

of 1 when hiring firm i is more profitable and 0 when source firm j is more profitable. This variable

accounts for baseline tendencies of partners to move between more or less profitable firms.

Two variables reflect the relative position of the two firms in the status and profitability

distributions, respectively. Average status is the average of hiring firm i’s status and source firm j’s status.

This variable captures any potential differences in the baseline likelihood of a lateral transition when the

firms are high in status compared to when both firms are low in status3. Similarly, average profit is the

average of hiring firm i’s PPEP and source firm j’s PPEP.

Because growing and contracting organizations differ in their propensities to hire or lose

employees (Freeman and Hannan, 1975), we include four control variables to account for the propensities

of firm i and firm j to hire or lose partners each year. We include the previous year’s counts of partner

hires by i, departures from i, hires by j, and departures from j. We include two more specific control

variables to account for prior movement of partners between i and j, because such hires may enable

3 Note that because we estimate models with upward and downward status differentials in our analyses, it is not

possible to also include variables for firm i status and firm j status.

15

employers to learn about potential candidates or candidates to learn about potential employers. Firms

might also hire individuals from the same competitors from which it hired in the past, based on co-worker

complementarities (Eisenhardt and Schoonhoven, 1990). Therefore, we include number of partner hires

by firm i from firm j in the prior year and departures from firm i to firm j in the prior year. These

variables also serve as controls for otherwise unobserved differences across dyads.

Areas of legal practice vary across firms. For most firms in our sample, we collected data on firm

practice areas from the annually published Vault Guide to the Top Law Firms. We then constructed a

measure of practice area overlap between i and j as follows:

∑ ∑ ∑

where takes a value of 1 if firm i is in practice area k and 0 otherwise, and likewise takes a value

of 1 if firm j is in practice area k and 0 otherwise. The numerator counts the number of practice areas

common to both firms, and the denominator normalizes by the number of practice areas that are present in

either firm. In other words, this variable is a Jaccard coefficient that indexes the intersection of two sets as

a proportion of their union, taking a value of 1 when two sets are identical.4 In our sample, practice

overlap is roughly normally distributed (mean = 0.29; s.d. = 0.13) and exhibits near-zero correlations with

the dyadic status (-0.07) and profitability (-0.09) differentials. These figures suggest that status and

profitability differences are unlikely to absorb the effects of unmeasured differences in practice areas.

But, for all dyads for which we obtained practice area for both firm i and firm j (87 percent of all dyads)

we subject our key findings to accounting for practice area overlap.

Dyadic observations are not independent because firms appear in multiple dyads. We include

Lincoln’s (1984) autocorrelation control variable, which for a given dyad of hiring firm i and source firm

j is the mean value of the dependent variable across all other dyads in which either i or j appears. This

4 This parsimonious control variable is preferable to manually coding practice areas for tens of thousands of lawyers

for each year in order to construct a more fine-grained measure of headcount-weighted, practice area overlap.

variable controls for firm-level tendencies to hire or lose lawyers each year.5 All hiring models include

unreported year fixed effects to account for secular trends in lateral hiring; no constant is reported because

the constant represents the omitted year’s effect. Table 2 presents descriptive statistics and correlations

for all variables included in the analyses.

Figure 2 depicts conditional probabilities of hiring from a more profitable competitor and losing

an employee to a lower status competitor – comparisons relevant to Hypotheses 3 and 4. These

probabilities are obtained from summary statistics and not from multivariate regression coefficients. A

few observations are noteworthy. First, consistent with a positive correlation between organizational

status and profitability (in our sample, the firm-level pairwise correlation is 0.76), in the vast majority of

at-risk dyads the hiring firm i is, relative to source firm j, either (1) higher in status and higher in

profitability or (2) lower in status and lower in profitability. The light grey rectangles represent such

dyads; note the much larger dyad count (64, 289 vs. 17,383 or 17,060). Although fewer dyads deviate

from the positive status-profitability correlation (the black rectangles), the rate of lateral hiring is

significantly more likely when one differential is positive and one is negative than when both profitability

and status differentials are positive or both are negative.

Second, consistent with a status-based hiring advantage, the probability of hiring an employee

from a more profitable competitor is significantly greater if the hiring firm is higher in status than if the

hiring firm is lower in status than the competitor (2.3% vs. 2.1%). Third, consistent with a status-based

retention advantage, the probability of losing an employee to a lower status competitor is significantly

greater if the competitor is more profitable than if the competitor is less profitable than the source firm

(3.2% vs. 2.1%). These comparisons suggest that high status organizations have labor market advantages

in hiring and retaining employees; our dyadic analyses account for alternative explanations.

Results

Table 4 reports results of rare-event logit models of the likelihood that firm i hires a partner from

firm j in year t. Model 1 is the baseline model specification with only control variables. Several variables

increase the baseline likelihood of lateral hiring. The likelihood increases with similarity in size and with

geographic proximity. The likelihood that a firm i hires from firm j increases with the number of partners

in the prior year who departed firm i, departed firm j, moved from firm j to firm i, and moved from firm i

to firm j. The higher the mean status of the dyad, the more likely it is that one firm hires from the other.

Finally, the higher the dyad’s mean profitability the less likely it is that one firm hires from the other.

-----------------------------------------

-----------------------------------------

Model 2 includes three variables to test for effects of status differentials on the likelihood of firm

i hiring from firm j: (1) the absolute status differential when the hiring firm is higher in status, (2) the

absolute status differential when the hiring firm is lower in status, and (3) a variable that indicates

whether the hiring firm is higher in status. Consistent with Hypothesis 1, the larger the status difference

between two firms, the lower the likelihood that one will hires the other. This effect is true for both

negative and positive status differentials.

Model 3 includes three variables to examine effects of profitability differentials on the likelihood

of firm i hiring from another firm j: (1) the absolute profitability differential when the hiring firm is more

profitable, (2) the absolute profitability differential when the hiring firm is less profitable, and (3) a

variable that indicates whether the hiring firm is more profitable. Consistent with Hypothesis 2, the larger

the profitability difference between two firms, the less likely it is that one firm hires from the other. This

effect is true for both negative and positive profitability differentials.

We then examine hiring and retention advantages of status. Model 4 provides a test of

Hypothesis 3. In Model 4, hiring from more profitable competitors corresponds to the variables indicating

that Pi < Pj. Hypothesis 3 predicts that higher status firms are more likely to hire from more profitable

competitors than are lower status firms. This implies that the variable for [Si>Sj , Pi<Pj] should have a

larger coefficient than the variable for [Si<Sj , Pi<Pj]. The coefficient and error estimates for these two

variables support Hypothesis 3. The variable for [Si>Sj , Pi<Pj] has a positive coefficient that is

significantly different from the baseline, while [Si<Sj , Pi<Pj] is not significantly different from the

baseline. The difference between the two coefficients is statistically significant (p<0.001), implying that a

firm is more likely to hire from a more profitable competitor when the firm’s status exceeds the

competitor’s status than when the competitor’s status exceed the hiring firm’s status.

Hypothesis 4 predicts that the probability of losing employees to a lower status competitor is

more likely when the competitor is more profitable. This implies that the variable for [Si<Sj , Pi>Pj]

should have a larger coefficient than the variable for [Si<Sj , Pi<Pj]. Support for this prediction is found in

the coefficient and error estimates for these two variables in Model 4. The variable for [Si<Sj , Pi>Pj] has

a positive coefficient that is significantly different from the baseline, while [Si<Sj , Pi<Pj] is not

significantly different from the baseline. The difference between the two coefficients is statistically

significant (p<0.001). This implies that a firm is more likely to lose employees to a lower status

competitor when the competitor is more profitable than when the competitor is less profitable.

In Model 5, we further probe Hypotheses 3 and 4. As prior models indicate, firms typically do not

hire from more profitable competitors or lose employees to lower status competitors. In other words,

profitability and status differentials have negative marginal effects on the likelihood of hiring. But,

Hypothesis 3 suggests that status helps hiring firms overcome negative profitability differentials.

Hypothesis 4 suggests that although profitability helps firms overcome negative status differentials, lower

status competitors must be – atypically – more profitable than a higher status competitor to hire an

employee away from that competitor. To test these implications, we examine whether or not the marginal

effects of status and profitability differentials differ across the conditions represented in Figure 2. If

higher status allows a firm to hire from more profitable competitors than it could otherwise, then the

effect of |Profitability differentialij|, Pi < Pj , which is typically negative, should be weaker when Si > Sj

than when Si < Sj. The estimates in Model 5 suggest that this is the case. The variable |Profitability

19

differentialij|, Pi < Pj , Si > Sj has no significant effect, while the variable |Profitability differentialij|, Pi <

Pj , Si < Sj has a significant negative effect.

Using coefficients from Model 5 in Table 4, Figure 3 plots the marginal effect of source firm j’s

higher profitability on the likelihood that firm i hires from firm j. Dark black lines represent all dyads in

which hiring firm i is lower in status than source firm j; light gray lines represent dyads in which i is

higher in status than j. Solid lines represent the estimated marginal effect, bounded by a dashed line 95

percent confidence interval. When firm i is lower in status than firm j, the confidence interval for the

marginal effect of j’s profitability differential is below zero, implying a significant negative effect on the

likelihood of hiring. But, when firm i is higher in status than j, the confidence interval is not statistically

different from zero except when j is much, much more profitable than i. At almost all points the

confidence intervals do not intersect, indicating that the marginal effect of j’s profitability differential is

significantly stronger when firm i is lower in status than when firm i is higher in status.

To put these effects in context, a firm’s probability of hiring from a higher status competitor

decreases by 10 percent for every $100,000 more in profits per equity partner that the competitor makes

relative to the firm6. Conversely, for higher status firms, the probability of hiring from a more profitable

competitor decreases by only 0.05 percent for every $100,000 more in profits per equity partner that the

competitor makes relative to the firm. The confidence intervals imply that when higher status firms can

just as easily hire from more profitable competitors that make up to $1 million more in profits per equity

partner as they can from equally profitable competitors. Consistent with a status-based hiring advantage,

high status firms are more likely to hire more profitable competitors’ employees than are low status firms.

-----------------------------------------

-----------------------------------------

Model 5 also examines retention advantages of status. If lower status competitors must be more

profitable in order to hire a higher status firm’s employees, then the effect of |Status differentialij|, Si < Sj ,

6 The marginal effect of a competitor’s profitability differential on probability of hiring is -0.002 per $100,000 in

profits per equity partner. A change of -0.002 represents a 10 percent decrease relative to the unconditional

probability of hiring, which is 0.2.

20

which is typically negative, should be weaker when Pi > Pj than when Pi < Pj. The estimates in Model 5

suggest that this is so. The variable |Status differentialij|, Si < Sj and Pi > Pj has no significant effect, while

the variable |Status differentialij|, Si < Sj and Pi < Pj has a significant negative effect.

Using coefficients from Model 5 in Table 4, Figure 4 plots the marginal effect of a firm’s greater

status over a competitor on the firm’s likelihood of losing employees to that competitor. Note that in this

case the competitor is the hiring firm, and, therefore, denoted by subscript i. Dark black lines represent

cases in which i is less profitable than j and light gray lines represent cases in which i is more profitable

than j. Solid lines represent the estimated marginal effect, bounded by a dashed line 95 percent

confidence interval. When a competitor is less profitable than a firm, the confidence interval for the

marginal effect of the firm’s status differential over the competitor is below zero, implying a significant

negative effect on likelihood of losing employees to that competitor. But, when a competitor is more

profitable than the firm, the confidence interval includes zero, implying no significant effect. At all

points, the confidence intervals do not intersect, indicating that the marginal effect of a firm’s positive

status differential is significantly stronger when competitors are less profitable.

To put these effects in context, when a competitor is less profitable than a firm, the firm’s

probability of losing an employee to that competitor decreases by approximately 40 percent for every 1

unit higher in status than the competitor (approximately 25 ranks higher).7 Conversely, the probability of

losing an employee to a more profitable competitor is insensitive to the dyad’s status differential.

Consistent with a status-based retention advantage, high status firms typically lose employees to lower

status competitors only if those competitors are, atypically, also more profitable.

Robustness checks. We check the robustness of our results to alternative analytical decisions.

One concern is that status and profitability differentials might absorb the effects of unmeasured

7 The marginal effect of a firm’s status differential on probability of losing an employee is -0.008 per 1 unit in status.

A change of -0.008 represents a 40 percent decrease relative to the unconditional probability of hiring, which is 0.2.

21

differences in practice areas between firms, which could affect the likelihood of hiring. In Model 6 we

estimate the fully specified model on the sub-sample of dyads for which we have practice area

information for both i and j (87 percent of all dyads). Greater practice area overlap does indeed have a

significant positive effect on the likelihood of hiring. But, the coefficient estimates for status and

profitability differentials are virtually identical in specifications that do and do not include this overlap

variable. Given the various lagged dependent variables already included in the specification, this seems

unsurprising. But, our findings seem insensitive to practice differences across dyads.

Another possible concern is non-independence of observations, which potentially affects our

sample in two ways. First, dyadic differentials may be correlated over time and, therefore, dyads are not

independent. Second, the dyadic nature of the data means that each firm i appears across multiple

observations, and i’s attributes do not vary within year. The same is true for each firm j. If the main

effects of interest are primarily being driven by variation in firm-level attributes – e.g. by just the hiring

firm’s status rather than dyadic differentials – then standard errors could be underestimated because firm-

level attributes are not independent across dyads.

Table 4’s results are conditional on our use of Lincoln’s (1984) method and clustering errors at

the dyad level. In supplementary analyses, we instead clustered on firm i and firm j and found results

consistent with those reported here. More conservatively, we also used two-way clustering to

simultaneously account for non-independence across all dyads containing firm i and all dyads containing

firm j (Petersen, 2009). When observations are not independent, two-way clustering simultaneously on

multiple non-nested groupings produces the largest standard error estimates in dyadic data and therefore

the most conservative coefficient estimates. Our main results are virtually identical across all clustering

approaches.8 Based on these analyses and the descriptive statistics, we are confident that our results are

not merely attributable to the non-independence of observations.

Another possible concern is that we have treated status and profitability differentials between

firms as varying continuously when categorical differences might be more relevant. Although our

22

hypotheses are supported with both dichotomous and continuous differential measures in Table 4, we

probed this issue more extensively. Specifically, we divided firms into five status tiers and five

profitability tiers, where the highest tier consists of the top-25 firms, the next tiers contain firms ranked 26

to 50, 51 to 75, 76 to 100, and the last tier contains firms ranked below than 100 (including unranked

firms). This approach accounts for the possibility that the Vault prestige scores are overly precise or that

the AM Law profitability figures are extensively managed by firms on a year-to-year basis.

In Model 7 of Table 5 we replace the continuous status differentials with dummy variables,

indicating whether firm i is in a higher status tier (Si > Sj) or lower status tier than firm j (Si < Sj). The

excluded category represents dyads in which the two firms are in the same status tier (Si = Sj). We

similarly replace the continuous profitability differentials with dummy variables, indicating whether firm

i is in a higher profitability tier (Pi > Pj) or a lower profitability tier than firm j (Pi < Pj). The excluded

category includes dyads in which the two firms are within the same profitability profit tier (Pi = Pj). The

coefficients for all four dummy variables are negative and significantly different from the baseline,

supporting Hypotheses 1 and 2. Firms are less likely to hire from competitors in higher or lower

profitability tiers than from competitors in the same profitability tier. Firms are also less likely to lose

employees to competitors in lower or higher status tiers than to competitors in the same status tier.

-----------------------------------------

Insert Table 5 About Here

-----------------------------------------

Model 8 examines the implications of tiers for hiring and retention advantages. Here, the

excluded category consists of dyads in which the two firms are in the same profitability and same status

tier (Si=Sj , Pi=Pj). Hypothesis 3 implies that the variable for Si>Sj , Pi<Pj should have a larger coefficient

than the variable for Si<Sj , Pi<Pj. Support for this prediction can be easily seen in the coefficient and

error estimates for these two variables in Model 8. The difference is statistically significant (p<0.001). A

firm is more likely to hire from a competitor in a higher profitability tier when the hiring firm is in a

higher status tier. Hypothesis 4 implies that the variable for Si<Sj , Pi>Pj should have a larger coefficient

23

than the variable for Si<Sj , Pi<Pj. Support for this prediction is seen in the coefficient and error estimates

for these two variables in Model 8. The difference between the two coefficients is statistically significant

(p<0.001). A firm is more likely to lose employees to a competitor in a lower status tier when the

competitor is in a higher profitability tier. These results further support Hypotheses 3 and 4.

Consistent with our results using continuous status and profitability differentials, we also find that

being in a higher status tier weakens the negative marginal effect of the profitability differential on a

firm’s likelihood of hiring from a higher profitability tier. When a firm is lower in status, it is less likely

to hire from a competitor in a higher profitability tier than a competitor in the same profitability tier. But

when a firm is in a higher status tier, it is no less likely to hire from a competitor in a higher profitability

tier than to hire from a competitor in the same profitability tier9. These results further support our

argument that high status firms have a hiring advantage over lower status competitors. We also find that a

competitor has to be in a higher profitability tier to weaken the negative marginal effect of status

differential on its likelihood of hiring from a higher status tier. When a competitor is less profitable, it is

less likely to hire from a firm in a higher status tier than a firm in the same status tier. But when a

competitor is in a higher profitability tier, it is no less likely to hire from a firm in a higher status tier than

to hire from a firm in the same status tier10

. These results further support our argument that high status

firms have a retention advantage over lower status competitors.

Concluding Discussion

9 The coefficient for Si<Sj , Pi<Pj is significantly smaller than the coefficient for Si<Sj , Pi=Pj (p<0.001) but the

coefficient for Si>Sj , Pi<Pj is not significantly different from the coefficient for Si>Sj , Pi=Pj (p=0.66). There is,

therefore, a significant difference between higher and lower status firms in the degree to which the likelihood of

hiring decreases when hiring from a higher versus same profitability tier. The difference given by Si<Sj , Pi<Pj -

Si<Sj , Pi=Pj is significantly larger than the difference given by Si>Sj , Pi<Pj - Si>Sj , Pi=Pj (p<0.001). 10

The coefficient for Si<Sj , Pi<Pj is significantly smaller than the coefficient for Si=Sj , Pi<Pj (p<0.001) but the

coefficient for Si<Sj , Pi>Pj is not significantly different from the coefficient for Si=Sj , Pi>Pj (p=0.53). There is,

therefore, a significant difference between more and less profitable competitors in the degree to which the likelihood

of hiring decreases when hiring from a higher status versus same status tier. The difference given by Si<Sj , Pi<Pj -

Si=Sj , Pi<Pj is significantly larger than the difference given by Si<Sj , Pi>Pj - Si=Sj , Pi>Pj (p<0.001).

Departing from the established product market advantages of organizational status, we argued

that status is also advantageous in labor markets because employer status is a basis for non-pecuniary

employment benefits. By integrating the economic theory of equalizing differences with the status based

model of market competition, we contribute to organizational theory the insight that organizational status

aids in hiring and retaining employees. We demonstrate two labor market advantages of organizational

status. First, high status firms are more likely to hire employees from more profitable competitors than

low status firms are. Second, high status firms are most likely to lose employees to lower status

competitors when those competitors are atypically more profitable. Both findings run counter to the

central tendency of organizations to hire individuals from competitors of similar profitability and status.

Several conditions bound the generalizability of our findings. First, the theorized trade-offs

between pecuniary and non-pecuniary benefits are probably most advantageous in human capital

intensive industries (e.g., professional services) in which employees represent the primary production

technology and large capital investments are atypical. Status is, of course, particularly valuable in such

industries because quality is difficult to verify ex ante. Second, the legal profession is characterized by

increasing mobility and a common method for delineating employee contributions to organizational

profitability (i.e., a partner’s “book of business”). Future research might test our arguments in settings

where individuals’ contributions are not so readily delineated.

Third, we explicitly assumed – based on prior research – that pecuniary and non-pecuniary

benefits vary, respectively, with organizational profitability and status. Although we cannot observe

employment terms in our data, recent work is consistent with our arguments (Bidwell, et al., 2013). Our

findings indicate that status is advantageous in hiring from more profitable competitors and that

profitability is advantageous in hiring from higher status competitors. Future studies might estimate the

implied exchange rate between pecuniary benefits and employer by analyzing job offer data for senior

employees who, if hired, seem most likely to enhance employer status and profitability.

More broadly, our findings are relevant for the study of individual status attainment. Our results

suggest that most inter-organizational transitions offer individuals only marginal improvements in

Page 27: Labor market advantages of organizational status: A study ...€¦ · large U.S. law firms demonstrate two status-based advantages in employee hiring and retention. First, high status

25

pecuniary and non-pecuniary benefits because the baseline tendency is to move between organizations of

similar status and profitability. Moreover, a substantial increase in employer status is likely to necessitate

compromising on pecuniary benefits because high status organizations are more likely to hire individuals

from more profitable competitors than low status organizations are. Conversely, a substantial increase in

pecuniary benefits is likely to necessitate compromising on intraprofessional status because more

profitable organizations are more likely to hire employees from high status competitors than low status

competitors are. Based on these findings, individual status attainment studies might consider more

broadly the trade-offs that individuals accept to work for particular employers (e.g., Stern, 2004).

At the organization and industry levels, our results suggest that lateral hiring stabilizes industry

status hierarchies. Low status organizations that exhibit atypically high profitability are most likely to hire

employees away from higher status but less profitable competitors. But, these organizations are also at

greatest risk of losing employees to those competitors. When a low status organization is most likely to

capitalize on atypically high profitability, it is also most vulnerable to losing the employees responsible

for producing profits. Conversely, when a high status organization is most likely to lose employees due

to low profitability that organization is also likely to shore up profitability by hiring employees away

from more profitable competitors. These scenarios imply that high status organizations likely restore

profitability to levels consistent with their status via hiring while low status organizations find it difficult

to sustain abnormally high profitability that might enhance their status. Future research might, therefore,

investigate hiring from competitors as a mechanism that reproduces the frequently-observed positive

correlation between organizational status and profitability. Such inquiries would answer recent calls to

investigate how dyadic exchanges shape status hierarchies (Lynn, Podolny, and Tao, 2010; Sauder, Lynn,

and Podolny, 2012).

Our arguments imply that hiring aids organizational status attainment, a phenomenon that has

received much less attention than individual status attainment has (see Lin, 1999 for a review) but seems

to be attracting growing scholarly interest. For example, Tortoriello, et al., (2011) theorize status-seeking

organizational behavior but, empirically, analyze how such objectives condition inter-organizational

Page 28: Labor market advantages of organizational status: A study ...€¦ · large U.S. law firms demonstrate two status-based advantages in employee hiring and retention. First, high status

26

exchange, not intra-organizational status change. Cowen (2012) ambitiously models changes in status for

banks but restricts her sample to 123 banking merger and acquisitions instead of the entire banking status

hierarchy. Others analyze larger samples but model status change based on the deference an actor receives

from alters (Bothner, Smith, and White, 2010; Askin and Bothner, 2012). Surprisingly, no prior studies

directly address the question of whether or not strategic efforts to attain greater status actually produce

benefits in excess of attainment costs.

Hiring seems one mechanism by which organizations gain and lose status. Alternatively,

preparing employees for positions at higher status employers might also influence status changes through

status transfer (Baty, et al., 1971; Podolny and Phillips, 1996). Consider that the “entrepreneurs as

organizational products” literature demonstrates that some organizations prepare employees for

entrepreneurship better than others (Freeman, 1986; Burton, et al., 2002). Similarly, many individuals

believe that some organizations are better than others at preparing employees for future attainment (e.g.,

Bidwell, et al., 2013). Other work documents how employees’ prior employment affiliations benefit

employers (e.g., Carnahan and Somaya, 2013). In contrast to extant research that treats lateral hiring as

potentially deleterious to organizations (e.g., Coff, 1997; Hillman, 2002; Broschak, 2004; Gardner, 2005),

future work might consider that losing employees to higher status competitors might be status-enhancing

for both individual and organization.
