FOMC MinutesMeeting of September 21, 2010
• “Many” see slow economic growth ahead and unemployment above levels associated with structural factors. “Most” see underlying inflation somewhat below levels consistent with mandate.
• “Many” see further accommodation as appropriate if these conditions persist. Method: Focus on Treasury purchases and on steps to affect inflation expectations
• Possible actions to affect inflation expectations
– Clarify inflation rate that FOMC sees as consistent with mandate
– Price-level target
– Nominal GDP target
• Policy effect depends on communicating framework

Marginally Attached?
• Marginally attached workers are persons who currently are neither working nor looking for work but indicate that they want and are available for a job and have looked for work sometime in the recent past.
• Discouraged workers, a subset of the marginally attached, have given a job-market related reason for not looking currently for a job.
• Persons employed part time for economic reasons are those who want and are available for full-time work but have had to settle for a part-time schedule.

• Institutions
– Contracting policy, minimum wages, etc.
• Physics
– It takes time to match workers and jobs

• Overtime– PRT Mandatory premium for overtime
work ranges from 50% to 75%, additional restrictions on night work, and there are 24 days of paid leave per year

Yogi vs. Tin Man
• Dismissal – PRT Has a list of fair grounds for
termination and stringent procedural limitations on dismissals, such as mandatory notification of the government and priority rules for re-employment of redundant workers.
– NZL Allows “contracts at will,” which can be terminated with notice without cause Source: Botero, Djankov, La Porta, Lopez-de-Silanes, Shleifer, 2003

Yogi vs. Tin Man
• Collective bargaining– PRT Employers have a legal duty to bargain
with unions, collective agreements are extended to third parties by law, workers councils are mandatory, and employer lockouts are prohibited.
– NZL Employers have no legal obligation to bargain with unions, collective agreements are not legally extended, labor participation in management is not required by law, and employer lockouts are allowed.Source: Botero, Djankov, La Porta, Lopez-de-Silanes, Shleifer, 2003

What’s going on in France?
• Gary Becker: “Generous minimum wages and other rigidities of the French labor market caused unemployment rates that have remained stubbornly high since the early 1990's. Immigrants, youths, and other new entrants into the labor market have been hurt the most.”

Volatility and employment
• Demand for labor is volatile– How does labor market flexibility affect
labor market outcomes?– What role do institutions play?

Labor market turnover
• Creation and destruction of jobs by firms – Creation: sum of all increases in number of employees by
individual establishments
– Destruction: sum of all decreases in number of employees by individual establishments
• Changes in job status by workers – Accessions: number of workers taking new jobs, whether
their previous status was employed, unemployed, or not in labor force
– Separations: number of workers leaving current jobs, whether they become employed, unemployed, or leave labor force
• Bottom line from both: enormous turnover

Volatility
• How do economies respond to shocks?
• Use our model– Begin in steady state– “Displace” some workers: higher
unemployment– How does the economy return to steady
state?

What have we learned today?
• Wide variation in labor market institutions
• Connection between institutions and outcomes
• Flexible labor markets – Lower steady state unemployment– Quicker response from shocks – Good? Bad? For whom?
