Governance and Deforestation Due to Agricultural Land Expansion

This article examines the effect of governance on forest cover in developing countries. We develop a theoretical model that explains how governance, particularly corruption control and politically stability, affects deforestation due to agricultural land expansion. The theoretical model shows the importance of the complementarity or substitutability of technology and land use in determining the effect of governance on agricultural land expansion and, consequently, forest cover. We complement the theoretical model with a structural empirical analysis to measure the effect of corruption control and political stability on deforestation in developing countries through two direct channels of deforestation: agricultural land expansion and road building. We find that political stability has a positive and significant effect on forest cover but corruption control has a negative and significant effect on forest cover due to increased agricultural land expansion.Deforestation, Governance, Corruption, Political stability

Revenue-Neutral Tax-Subsidy Policy for Carbon Emission Reduction

One of the benefits of biofuel use is a reduction in greenhouse gas emissions relative to fossil fuels, but no policy directly targets carbon emissions across the full spectrum of renewable and nonrenewable fuels. In light of the political unpopularity of carbon taxes in the United States, we develop a model for a revenue neutral price instrument that maximizes social welfare subject to an exogenously determined net tax revenue target. This approach may be more palatable because it has the potential to change the relative price of the low-carbon and highcarbon components of blended fuel while limiting increases in taxes and motor fuel prices. Our model shows that the targeted tax revenue level and share of output to total gross domestic product in all fuel sectors are important factors determining the revenue-neutral tax levels for each fuel type. Interestingly, we also find that the marginal damages of pollution are not the primary determinants of the revenue neutral price instrument, but instead it is the relative marginal damages per unit price of each fuel type. This implies the counterintuitive possibility that with a revenue neutrality constraint, higher net carbon emitting fuels such as gasoline or diesel may implicitly be subsidized using revenues from carbon taxes on lower emitting fuels.Non-renewable resources, carbon tax, carbon dioxide emissions, revenue recycling, revenue neutral

Was It Something I Ate? Implementation of the FDA Seafood HACCP Program

We use FDA’s seafood inspection records to examine: (i) how FDA has targeted its inspections under HACCP regulation; (ii) the effects of FDA inspections on compliance with both HACCP and plant sanitation standards; and (iii) the relationship between HACCP regulations and pre-existing sanitation standards. We use a theoretical model of enforcement to derive hypotheses about FDA’s targeting of inspections and firms’ patterns of compliance. We test those hypotheses using econometric models of inspection and compliance. Contrary to the predictions of the theoretical model and to FDA’s own stated policies, FDA does not seem to have targeted inspections based on product risk or past compliance performance. Firms’ compliance strategies seemed to be broadly in accord with the predictions of the theoretical model. The threat of inspection increased the likelihood of compliance, although the deterrent effect was statistically significant for sanitation standards but not for HACCP. Firms tend to persist in compliance status, especially with respect to sanitation standards. Contrary to FDA’s presupposition, however, HACCP compliance does not improve compliance with sanitation standards, suggesting that the two are not complementary.HACCP, Food safety, Seafood, Enforcement, Regulatory compliance, Regulation

Pollution and the State: The Role of the Structure of Government

Government spending has significant environmental implications. This paper analyzes the effect of the allocation of government spending between public goods broadly defined and private goods or non-social subsidies on air and water pollution. The theoretical model predicts that a reallocation of expenditures from private subsidies to public goods improves environmental quality by reducing production pollution. We estimate an empirical model that shows that such a reallocation causes a significant reduction in air pollutants namely sulfur dioxide and lead and an improvement in water quality measures including dissolved oxygen and biological oxygen demand.

Long Term Versus Temporary Certified Emission Reductions in Forest Carbon-Sequestration Programs

Under the Clean Development Mechanism (CDM) of the Kyoto Protocol, forest projects can receive returns for carbon sequestration via two credit instruments: temporary (tCERs) or long-term certified emission reductions (lCERs). This article develops a theoretical model of optimal harvesting strategies that compares private optimal harvest decision under these two instruments. We find that risk neutral landowners are likely to prefer instituting lCERs over tCERs to maximize surplus. A particular type of early harvest penalty implemented under the lCERs is critical in determining the length of rotation intervals and the carbon credit supply. When this penalty is an increasing function of the difference in biomass before and after harvesting across verification periods, the landowner may choose longer or shorter rotation intervals compared to the Faustmann rotation. The resulting supply curve may have a backward bending region over a range of carbon prices.forest rotation, long term certified emission reductions (lCERs), carbon sequestration

The Amenity Value of Climate Change Across Different Regions in the United States

This article estimates the amenity value from climate change by analyzing the effect of climatic variables on house prices near ski resorts in different regions in the United States using a hedonic model. We find that higher average winter temperatures tend to increase house price near ski resorts at a decreasing rate. Using the implicit value of average winter temperature, we estimate its demand and find that the crossing point temperature, where the homeowner’s consumer surplus from average winter temperature moves from positive to negative, varies in each region. The highest crossing point temperature is in the Western region at 46°F and lowest is in the Midwest at 8°F. Based on projections in the next 30 years, we find that the consumer surplus from average winter temperature for the median home owner is negative in the Midwest and Northeastern regions where the crossing point temperatures are lowest and it is positive for the West and Mountain regions where the crossing point temperatures are highest. The long run effect of climate change on homeowner’s consumer surplus is negative for all regions

Trade Policies, Economic Growth, and the Direct Causes of Deforestation

This paper combines elasticities from microstudies with estimates from a cross-country analysis to identify structural relationships explaining deforestation in Brazil, Indonesia,Malaysia, and the Philippines. Economy-wide factors such as trade openness and economic growth explain an important portion of the variation in three key factors of deforestation: poverty, agricultural expansion, and road building. Trade increases forest cover in Brazil and in the Philippines, but has no significant effect in Indonesia and Malaysia. An important channel through which trade policy affects forests in all four countries is agricultural expansion. Economic growth has a negative and relatively large impact on forest cover.
