The Impacts of Environmental Regulations on Industrial Activity: Evidence from the 1970 & 1977 Clean Air Act Amendments and the Census of Manufactures
This paper estimates the effects of environmental regulations on industrial activity. The analysis is conducted with the most comprehensive data available on both regulations from the Clean Air Act Amendments' division of counties into pollutant-specific nonattainment and attainment categories and manufacturing activity from the 1.75 million plant observations that comprise the 1967-87 Censuses of Manufactures. Emitters of the controlled pollutants are subject to greater regulatory oversight in nonattainment counties. I find that in the first 15 years after the Amendments became law (1972- 1987), nonattainment counties (relative to attainment ones) lost approximately 590,000 jobs, 75 billion (1987$) of output in pollution intensive industries. These estimates are derived from a statistical model for plant-level growth that controls for plant fixed effects, unrestricted industry shocks, and unrestricted county shocks. Importantly these findings are robust across many specifications, and the effects are apparent across a wide range of polluting industries. Although the decline in manufacturing activity was substantial in nonattainment counties, it was modest compared to the size of the entire manufacturing sector.
Environmental Regulations, Air and Water Pollution, and Infant Mortality in India
Using the most comprehensive data file ever compiled on air pollution, water pollution, environmental regulations, and infant mortality from a developing country, the paper examines the effectiveness of India's environmental regulations. The air pollution regulations were effective at reducing ambient concentrations of particulate matter, sulfur dioxide, and nitrogen dioxide. The most successful air pollution regulation is associated with a modest and statistically insignificant decline in infant mortality. However, the water pollution regulations had no observable effect. Overall, these results contradict the conventional wisdom that environmental quality is a deterministic function of income and underscore the role of institutions and politics.
Does Hazardous Waste Matter? Evidence from the Housing Market and the Superfund Program
Approximately ) has been spent on Superfund clean-ups of hazardous waste sites, and remediation efforts are incomplete at roughly half of the 1,500 Superfund sites. This study estimates the effect of Superfund clean-ups on local housing price appreciation. We compare housing price growth in the areas surrounding the first 400 hazardous waste sites to be cleaned up through the Superfund program to the areas surrounding the 290 sites that narrowly missed qualifying for these clean-ups. We cannot reject that the clean-ups had no effect on local housing price growth, nearly two decades after these sites became eligible for them. This finding is robust to a series of specification checks, including the application of a quasi-experimental regression discontinuity design based on knowledge of the selection rule. Overall, the preferred estimates suggest that the benefits of Superfund clean-ups as measured through the housing market are substantially lower than the $43 million mean cost of Superfund clean-ups.
Is There an Energy Efficiency Gap?
Many analysts have argued that energy efficiency investments offer an enormous “win-win” opportunity to both reduce negative externalities and save money. This overview paper presents a simple model of investment in energy-using capital stock with two types of market failures: first, uninternalized externalities from energy consumption, and second, forces such as imperfect information that cause consumers and firms not to exploit privately-profitable energy efficiency investments. The model clarifies that only if the second type of market failure cannot be addressed directly through mechanisms such as information provision, energy efficiency subsidies and standards may be merited. We therefore review the empirical work on the magnitude of profitable unexploited energy efficiency investments, a literature which frequently does not meet modern standards for credibly estimating the net present value of energy cost savings and often leaves other benefits and costs unmeasured. These problems notwithstanding, recent empirical work in a variety of contexts implies that on average the magnitude of profitable unexploited investment opportunities is much smaller than engineering-accounting studies suggest. Finally, there is tremendous opportunity and need for policy-relevant research that utilizes randomized controlled trials and quasi-experimental techniques to estimate the returns to energy efficiency investments and the welfare effects of energy efficiency programs.
The Economic Impacts of Climate Change: Evidence from Agricultural Profits and Random Fluctuations in Weather
This paper measures the economic impact of climate change on US agricultural land by estimating the effect of the presumably random year-to-year variation in temperature and precipitation on agricultural profits. Using long-run climate change predictions from the Hadley 2 Model, the preferred estimates indicate that climate change will lead to a ) or 3.4% increase in annual profits. The 95% confidence interval ranges from -4.0 billion and the impact is robust to a wide variety of specification checks, so large negative or positive effects are unlikely. There is considerable heterogeneity in the effect across the country with California’s predicted impact equal to -$2.4 billion (or nearly 50% of state agricultural profits). Further, the analysis indicates that the predicted increases in temperature and precipitation will have virtually no effect on yields among the most important crops. These crop yield findings suggest that the small effect on profits is not due to short-run price increases. The paper also implements the hedonic approach that is predominant in the previous literature. We conclude that this approach may be unreliable, because it produces estimates of the effect of climate change that are very sensitive to seemingly minor decisions about the appropriate control variables, sample and weighting. Overall, the findings contradict the popular view that climate change will have substantial negative welfare consequences for the US agricultural sector.Cost of climate change, Hedonics, Agricultural profits, Agricultural production, Crop yields

The Economic Impacts of Climate Change: Evidence from Agricultural Profits and Random
This paper measures the economic impact of climate change on US agricultural land. We replicate the previous literature's implementation of the hedonic approach and find that it produces estimates of the effect of climate change that are very sensitive to decisions about the appropriate control variables, sample and weighting. We find estimates of the benchmark doubling of greenhouse gases on agricultural land values that range from a decline of ) to an increase of 40 to $80 billion, or 3% to 6%, but the null of zero effect cannot be rejected. In contrast to the hedonic approach, these results are robust to changes in specification. Since farmers can engage in a more extensive set of adaptations in response to permanent climate changes, this estimate is likely downwards biased, relative to the preferred long run effect. Together the point estimates and sign of the likely bias contradict the popular view that climate change will have substantial negative welfare consequences for the US agricultural sector.
Bidding for Industrial Plants: Does Winning a 'Million Dollar Plant' Increase Welfare?
Increasingly, local governments compete by offering substantial subsidies to industrial plants to locate within their jurisdictions. This paper uses a novel research design to examine the consequences of successfully bidding for a plant on county-level labor earnings, property values, and public finances. Each issue of the corporate real estate journal Site Selection includes an article titled The Million Dollar Plant that describes how a large plant decided where to locate. These articles report the county where the plant chose to locate (i.e., the 'winner'), as well as the one or two runner-up counties (i.e., the 'losers'). The losers are counties that have survived a long selection process, but narrowly lost the competition. We use these revealed rankings of profit-maximizing firms to form a counterfactual for what would have happened in the winner counties in the absence of the plant opening. We find that a plant opening is associated with a 1.5% trend break in labor earnings in the new plant's industry in winning counties (relative to losing ones) after the opening of the plant (relative to the period before the opening). Property values may provide a summary measure of the net change in welfare, because the costs and benefits of attracting a plant should be capitalized into the price of land. We find a positive, relative trend break of 1.1% in property values. Further, we fail to find any deterioration in local governments' financial position. Overall, the results undermine the popular view that the provision of local subsidies to attract large industrial plants reduces local residents' welfare.
Climate Change, Mortality, and Adaptation: Evidence from Annual Fluctuations in Weather in the US
This paper produces the first large-scale estimates of the US health related welfare costs due to climate change. Using the presumably random year-to-year variation in temperature and two state of the art climate models, the analysis suggests that under a "business as usual" scenario climate change will lead to an increase in the overall US annual mortality rate ranging from 0.5% to 1.7% by the end of the 21st century. These overall estimates are statistically indistinguishable from zero, although there is evidence of statistically significant increases in mortality rates for some subpopulations, particularly infants. As the canonical Becker-Grossman health production function model highlights, the full welfare impact will be reflected in health outcomes and increased consumption of goods that preserve individuals' health. Individuals' likely first compensatory response is increased use of air conditioning; the analysis indicates that climate change would increase US annual residential energy consumption by a statistically significant 15% to 30% (35 billion in 2006 dollars) at the end of the century. It seems reasonable to assume that the mortality impacts would be larger without the increased energy consumption. Further, the estimated mortality and energy impacts likely overstate the long-run impacts on these outcomes, since individuals can engage in a wider set of adaptations in the longer run to mitigate costs. Overall, the analysis suggests that the health related welfare costs of higher temperatures due to climate change are likely to be quite modest in the US.
