Benefits & Costs of Regulations: Measuring Costs
Understanding costs is important since policies often(1) involve substantial individual sacrifice, and (2) generate costs that are distributed unevenly
• “Roughly 2% of (U.S. GDP) is spent on environmental protection.”
• CBAs “of environmental regulation tend to focus on aggregate consequences” – “Yet these consequences are not evenly distributed
among all members of society” – there is a distribution of costs which can be “broken
down by household, sector, region, and generation.”

Greenstone (2002) argues: Environmental regulations can cost jobs
• Greenstone (2002): “The Impacts of Environmental Regulations on Industrial Activity: Evidence from the 1970 and 1977 Clean Air Act Amendments and the Census of Manufactures”
• “…first 15 years after the Amendments became law (1972- 1987):– nonattainment counties (relative to
attainment ones) lost approximately • 590,000 jobs, • $37B in capital stock, and • $75B (1987$) of output in pollution intensive
industries”.“…undermine(s) the contention that environmental regulations are costless or even beneficial for the regulated.”
(Coglianese et al. 2013)
(Coglianese et al. 2013)
• Question: Does a “jobs versus the environment” trade-off exist?
• Morgenstern et al. consider four heavily polluting industries:
• pulp and paper mills• plastic manufacturers• petroleum refiners• iron and steel mills
• Results• average across four industries:
net gain of 1.5 jobs per $1 million in additional environmental spending,
• with a standard error of 2.2 jobs
• economically and statistically insignificant effect.
Morgenstern et al. (2002) find: increased environmental spending generally does not cause a significant change in employment
Executive branch agency regulations generally have positive net benefits
The true economic costs of environmental protection are the opportunity costs
– (Social) opportunity costs: the highest-value alternative use to which inputs (resources) might have been put and that society has to forego when the inputs are used.
– What you give up by taking one action and not another• What’s the cost of attending UCD?
– “Sticker” price? The opportunity cost?
– NB of the best alternative opportunity foregone
Most generally, the economic costs of environmental protection are the opportunity costs
Example: tradeoffs between species preserved and development benefits from alternative land use configurations in the Willamette Valley (OR)
[Polasky et al. 2008]
Taxonomy of costs: most obvious most comprehensiveeasiest to estimate hardest to estimate
Abatement costs (see detail in add’l slides at end)
– out-of-pocket costs for abatement equipment (used to reduce pollution)
Compliance costs– the cost of all policy compliance actions (captures costs outside of
abatement, e.g. process change).– may be sufficient when “behavioral response, transitional costs and
indirect costs are small” (Revesz and Stavins, 2007, 512).
Partial equilibrium/behavioral response– Captures behavioral responses (e.g. increased prod cost), but holds
prices constant, limited to burden on directly regulated entities (firms or households).
General equilibrium/Secondary effects– the net burden once all good and factor markets have equilibrated. (Pizer
and Kopp, 2005)
The results of environmental policies are likely to be regressive if equity concerns are ignored
• Regressive: an outcome in which poor individuals bare a relatively higher burden compared to wealthy individuals.
• Mechanism Env. and energy policy may raise the prices of goods and services that make up a greater share of expenditures for poor people.
(Bento 2013)
With and Without (WW) vs. Before and After (BA)Only incremental benefits and costs attributable to the project should be included – i.e. the analysis should be WW.
Panayotou (1997)
BA: bad
BA: bad
WW: good
With and Without (WW): good (actual incremental effect of policy)
After, with policy
After, without policy
After, without
BA under-estimates impact
BA over-estimates impact
Policies can involve implicit or explicit design choices that have substantial impacts on the way in which benefits and costs are distributed across society
income-based subsidy, specifically, more help for poor
age-based subsidy, specifically, more help for older (& less subsidy overall)
Policy cost example: “Distributional and Efficiency Impacts of
Increased US Gasoline Taxes”Bento et al. (2009)
• What happens when we impose a $0.25 tax on gasoline?
• Econometrically based multimarket simulation model.• Behavioral response:
– fuel consumption, – vehicle miles traveled (VMT)– fleet composition (new and used)
Bento et al. (2009)• Distribution across 20,000 households
– Varying: income, region of residence, race, and employment status
– Random sample, National Household Travel Survey
• Utility maximization framework– theoretically sound welfare indexes of
distributional impacts
Bento et al. (2009)
• Revenue recycling scenarios—distribute gas tax revenue by:– “Flat”: equal amounts to every household.– “Income-based”: according to income share– “VMT-based”: according to VMT share (baseline)
• Results: 25 cent tax welfare loss of $30/yr (2001$, avg per household)– Cost-side only, excludes external benefits
Welfare impacts by race & income(flat recycling)
EV: “equivalent variation” roughly, WTP to avoid the policy changeMore precisely, an individual is indifferent between these two options: (EV payment + no policy) ~ (no payment + policy proceeds)
For lowest income bracket: refund > taxes paid

Story: new regulation increases the MC of paper production from MC1 to MC2
1.What is the behavioral response: quantity supplied before versus after the reg.?
2.What are the implications for consumer surplus given a flat demand curve?
3.What is the area D+E in plain English? A reasonable est. of cost?
4.What is the increase in total cost of producing r1 after the regulation? Why might it be misleading to use this as an estimate of compliance cost?
5.What are the social costs of the regulation? (Note: we’re not looking at the benefit side of the policy now, just costs.)
When we account for behavioral responses in the regulated sector (but no further) we are conducting a “partial equilibrium analysis” (vs. a multi-sector general equilibrium).

***Video for this slide on course website (under ppt file): characterizing costs with behavioral response
“General equilibrium” or “secondary” effects are outcomes of a policy that extend beyond the primary market being regulated
When are secondary effects likely important? (RFF B-C primer)
1.For regulations that affect highly integrated sectors of the economy – Produce widely used intermediate products (e.g. energy)
2.Regulations that generate large direct costs
(Gerege Partners)
– If costs are passed to consumers their overall consumption might fall
– Industry may contract (employees reduced)
– Compliance industry might grow
Example: (1) Clean Water Act, and (2) Clean Air Act.
Hazilla and Kopp, 1990. “Social Cost of Environmental Quality Regulations: A General Equilibrium Analysis”
• Effects in table are just the compliance costs.
The secondary effect analysis (SEA): CAA/CWA example• SEA: A large mathematical model of consumers and producers
in many industries– Parameters of the model (e.g. how do consumers value consumption
versus leisure?) are estimated from historical data– Model is “run” twice
• Without the proposed policy (“baseline”, “counterfactual”)• With the proposed policy
• What kinds of behavioral links does it capture?
– Individual household choices: Regulation increases prices Price of consumption (versus leisure) goes up
People work less (labor supply falls), savings rate falls (capital supply falls) Individual (and therefore aggregate) economic growth is reduced
– Analogous story for firm decisions
Secondary effect analysis results (e.g. continued)
• Compliance investments: required in 13 sectors – BUT, production costs increased and output and labor productivity fell in all
sectors.– E.g. finance sector: bore no compliance cost, BUT cost of
production is 2% higher (higher input costs)
Conclusions of the study
Hazilla and Kopp, 1990. “Social Cost of Environmental Quality Regulations: A General Equilibrium Analysis”. Journal of Political Economy, vol. 98, no. 4 (August), pp. 853-873.
• In other words, regulation causes prices to rise but then consumers adapt, substituting towards other goods. Ignoring consumer response leads to a overstatement of costs of the CAA & CWA and therefore an understatement of net benefits.

Other cost issues• Dynamic: technological progress• Enforcement: gov. admin., monitoring and
enforcement• Environmental costs: e.g. S02 sludge from
scrubbers (risk-risk)• “Negative costs”: increases in productivity
from cleaner environment, process improvements from innovation spurred by regulation.
Environmental regulations can cost jobs
Conceptualization of cost for environmental policy: (Revesz and Stavins, 2007, 511)
– “(T)he value of whatever must be sacrificed to prevent (or reduce the risk of) an environmental impact.
– (T)he forgone social benefits due to employing
scarce resources for environmental policy purposes, instead of putting those resources to their next best use.”
Overall record of cost estimation• Harrington et al. (2000): examined 28
environmental and occupational safety regulations– Half the cases: cost estimates > actual costs
• Per-unit abatement costs: over- and under-estimation error equally common
– BUT: When economic incentives instruments used, per-unit costs were consistently overestimated.
• Attributed to technological innovation stimulated by market-based instruments.
(via Revesz and Stavins, 2007, 513)
Direct costs: Abatement • Abatement expenditures: out-of-pocket costs for
abatement equipment (used to reduce pollution) – Most popular (but poor) concept of regulatory cost in
the analysis of environmental programs

Example: costs of policy to ban CFCs
•Response: develop CFC replacements like freon.
•Possible costs
1. Replacement: Increased costs of production for the replacement
2. R&D: The diverted resources necessary to develop the substitute
3. Obsolescence: The value of services of specialized capital and technology
4. Consumer welfare: Change retail price of replacement (lost surplus)
