Incidence of Environmental Regulations
Who pays for environmental regulations, and how much?

Motivation
Group Project: One of the stipulations of AB32 is that environmental justice be taken into account in reducing GHG emissions. What are the environmental justice implications of a cap and trade system and how can the negative effects be reduced?

Some general rules
Only people gain and lose – not organizations. “Corporations” never pay. Corporations are just paper.
Corporation is owned by its shareholders – people. Consumers may benefit from improved environment and pay
higher price for goods (e.g. pesticide regulation). Impose a regulation, typically who pays:
Consumers Owners of inputs to production:
• Workers – owners of labor
• Shareholders – owners of capital Effects ripple through economy.

Example: New regulations on metal fabrication industry
Industry costs go up Can industry raise prices, passing on costs? Can industry lower wages to keep competitive?
Product price may go up Consumers will pay more Some consumers will do without
Conclusion: Consumers and capital owners pay Citizens benefit from better environment

Key terms
Backward Incidence: inputs pay (wage earners, capital owners, etc) Example: Regulation only covering California firms
Forward Incidence: consumers pay Example: Regulation covers all US firms and no
foreign competition Incidence by class: income, ethnicity, geographic
region, age, education, etc. Example: gasoline tax would fall heavily on the poor

Firms vs. consumers
First question is whether firms pay or consumers pay
If firms pay, next question is which inputs pay?LaborCapital

If producers pay, will owners of capital or labor end up paying?
Do employees have alternative job opportunities? If yes, then producer can’t pass on costs to labor.
Is capital mobile (fungible) or application specific? If mobile, then can’t pass on costs to capital.
If either capital or labor has few alternatives, then that factor will probably eat the cost.

Example 1: The Isla Vista cliffs
Isla Vista, CA: many houses on eroding sea cliffs; safety concern, eyesore, house stability concern
College community, mostly student rentals. Consider a publicly-funded project to shore
up the cliffs, paid for with an IV sales tax. Who would benefit from this action? Who would bear most of the costs?

The real question:Are residents (students) better off?
Conclusion: Landlords basic beneficiaries

Environmental Racism/Justice: A Special Kind of Incidence
Environmental Justice (EJ) is the fair treatment and meaningful involvement of all people regardless of race, color, natural origin, or income with respect to the development, implementation, and enforcement of environmental laws, regulations and policies. (EPA) EPA examples:
Low-income citizens, and quite often minorities, are more likely to live near landfills, incinerators, and hazardous waste treatment facilities.
Low-income and African American children consistently have higher than normal levels of lead in their blood and asthma conditions.
80 percent Hispanic, 65 percent African American, and 57 percent White people live in areas which fail to meet some U.S. EPA air quality standards.
Should “income” be included in this definition? If incinerator is choosing between locating in Bel Air or South Central LA, which
should it choose and why? Applies to acts of government (eg, regulations) and acts of firms (polluters)

Issues with environmental racism
Targeting regulations or plant siting based on race or ethnicity clearly wrong. Alesina et al (1999): shares of spending on public goods
in U.S. cities are inversely related to the city's ethnic fragmentation
Cutler and Glaeser (1997) African Americans in more segregated areas have significantly worse outcomes than African Americans in less segregated areas.
Targeting regulations or plant siting based on income is more complex Low land prices often attract low income residents Factories typically attracted by low land prices Low environmental quality often depresses land prices

What to do with incidence(in evaluating a policy/project)
Separately measure incidence and efficiency – two measures of the performance of a policy
Adjust cost-benefit analysis using income weights Track costs and benefits to different income
groups Weigh lower income groups higher than
higher income groups Size of weights difficult to determine

Why is incidence and justice in economics?
Framed as a positive question, totally appropriate for economicsDistributional consequences of an
action What to do about it is the reason we
have a political system – NOT an economics question
