  1. Measuring the Costs of Environmental Protection Chapter 9

  2. The Engineering Approach • Engineering approach to measuring costs • Add up all the expected expenditures by firms plus state, local, and federal governmental on pollution control and regulatory efforts • By far the most widespread method in use • Require making assumptions about future behavior

  3. EPA Cost Estimates

  4. Engineering Costs: Climate Stabilization Source: McKenzie

  5. Opportunity Cost • The value that resources generate in their next best available use • Only opportunity costs measure the true cost of environmental protection

  6. Overstatement of True Costs • Engineering cost estimates will overstate true social opportunity costs to the extent that environmental policies • Increase productivity • Reduce structural unemployment

  7. Understatement of True Costs • Engineering cost estimates will understate true social opportunity costs to the extent that environmental policy • Lowers productivity growth • Induces structural unemployment • Increases monopoly power in the economy

  8. Productivity Impacts of Regulation • The biggest unknown in estimating the costs of environmental protection is its impact on productivity • Some argue that environmental regulations have been a major contributor to the productivity slowdown • Others argue that pollution control efforts spur productivity growth by forcing firms to become more efficient

  9. Pro-Productivity Effects of Regulation 1. Improving the short-run efficiency of resource use, saving money for firms 2. Encouraging firms to invest more, or invest “smarter” for the long run • Porter Hypothesis: regulation, enhances long-run competitiveness • Regulation may play a technology-forcing role. 3. Reducing health-care costs or improving ecosystem services , which frees up capital for long-run investment

  10. Anti-Productivity Effects of Regulation • Regulation imposes direct costs on regulated firms that may crowd out investment in conventional capital • Slowdown in new investment may occur when regulation is more stringent for new sources of pollution (“grandfathering”) • Regulation will cause higher prices for important economy-wide inputs, further crowding out investment • Regulation may frustrate entrepreneurial activity– too much “red tape”

  11. The Cost of Regulation: Productivity Studies • Some data: (Barbara and McConnel) • 10% to 30% of the productivity decline in heavily industries could be accounted for by environmental regulation • Less than 10% to 20% of the post 1970 slowdown can be attributed to environmental regulation

  12. Employment Impacts of Regulation • Is a “hidden cost” of environmental protection job loss?

  13. Objections to the 1990 Clean Air Act Amendments: • “A minimum of 200,000 jobs will be quickly lost; this number could easily exceed one or two million” • It would “move the United States towards the status of a second-class industrial power by the end of the century” • Actual Job Loss: About 5,000 spread out over several states, and several years.

  14. Lessons Learned About Job Impacts • At the economy-wide level there is no trade-off between jobs and the environment • Green Jobs: Environmental Protection spending can boost net job growth when the economy is not at full employment. • Actual layoffs from environmental protection have been small (about 2,000-3,000 jobs per year) • Pollution intensive firms are not fleeing rich countries in large numbers to escape environmental regulation

  15. Economy-wide Effects • Regulations may contribute to localized structural unemployment, but this diminishes in the long run as displaced workers find new jobs elsewhere in the economy • Regulation does not create long-run unemployment; instead, it will contribute to a shift in the type of jobs the economy creates

  16. A Jobs-Environment Trade-off?

  17. Jobs Dependent on Environmental Spending

  18. Green Jobs • The bulk of environmental spending remains in the private sector, generating a demand for workers, primarily in manufacturing and construction • This money could have been spent on other things--health care, travel, investment, imported goods--so net job creation could have been higher or lower without environmental regulation

  19. Job Creation • As a rule, money spent on sectors that are both more labor-intensive and have a higher domestic content will generate more American jobs in the short run • Environmental spending is often either labor intensive or has a high domestic content • If the economy is not at full employment, then green spending can lead to more job growth than other types of spending.

  20. Jobs-Environment Trade-Off? • Most of the time, if you hear a sentence that begins with “All economists agree,” you should head for the door • But in this case, there is an agreement that at the economy-wide level there is simply no such thing as a jobs-environment trade-off

  21. What about layoffs from Regulation?

  22. Layoffs Due to Regulation • Employer estimates: environmental regulation accounts for less than one tenth of one percent of all mass layoffs nationwide • 7 plants per year closed primarily as a result of environmental problems • On average, 2,000-3,000 lost positions each year are due in part to environmental regulation • 40 times more layoffs are due to ownership changes than to regulation

  23. Pollution Havens? • Does new investment occur in poor countries with less stringent regulation—”pollution havens”—due to environmental regulation? • Very little evidence to suggest that the competitiveness of U.S. manufacturing firms have been hurt by environmental regulation

  24. Why the Small Effects? • Pollution control costs are a small portion of total business costs • Costs are only one factor influencing business decisions • Factors as diverse as access to markets and the quality of life are important components of business location decisions • Much pollution control technology is embedded in modern plant designs • Chemical plant built in South China will look like one built in West Virginia

  25. The Maquiladora Case • Plants within 100 kilometers of the U.S. border in Mexico, known as maquiladoras, may import and export products freely • These plants are required to meet U.S. environmental standard but in practice, the Mexican government has not rigorously enforced the law

  26. The Maquiladora Case • Mexico may attract investment that would occur in the U.S. had it not been for environmental regulations due to its: • Close proximity to the U.S. • Low wages • Lax environmental regulation • BUT: industries moving to Mexico are not heavily regulated dirty industries, but instead relatively “clean”, labor intensive assembly plants. Little evidence of “Pollution Haven” effects. • One Exception: Furniture Manufacturing

  27. Monopoly Costs? • Regulation can impose high fixed costs on firms • High fixed costs generate economies of scale which can cause smaller firms to be squeezed out of business • Thus, one potential cost of environmental regulation is an increase in monopoly power in the economy

  28. General Equilibrium Effects • The last important area in which there may be “hidden” costs (or benefits) of regulation lies in what economists call general equilibrium (GE) effects--the effects of regulation felt throughout the economy • General equilibrium effects might raise or lower costs by altering labor supply • This argument has loomed large in the debate over the so-called “double dividend hypothesis”

  29. The Double-Dividend Hypothesis • A shift to pollution taxes would not only reduce pollution, but by using the revenue to cut taxes on capital and labor, would make the whole economy operate more efficiently: thus two dividends to green taxes. • Lower taxes on work, for example, might cause people to work more hours, raising output.

  30. The Debate • On the other hand: Taxes on pollution lead to higher prices for dirty goods, which means that an hour of work buys fewer goods • In other words, the real wage falls and people substitute labor for leisure, and work less • Economists are debating whether these general equilibrium effects lower or raise the net costs of regulation.
