How governments regulate food safety and environmental protection, including pesticide residue levels, has important implications for trade. The World Trade Organization (WTO) Ministerial held in Doha, Qatar in November 2001 included statements on standards and their impact on market access for developing countries. These issues will continue to be important in trade policy dialogues. It is assumed - and evidence from recent analysis confirms - that food safety standards can affect the ability of agricultural producers to meet regulatory standards set by importing countries. Wilson and Otsuki explore a fundamental question in food safety and environmental standards: Do regulations on pesticide have an effect on trade?The authors examine regulatory data from 11 OECD importing countries and trade data from 19 exporting countries. The results suggest that a 10 percent increase in regulatory stringency - tighter restrictions on the pesticide chlorpyrifos - leads to a decrease in banana imports by 14.8 percent. This represents a significant impact on trade and affect prospects of developing countries who continue to rely on exports of agricultural commodities, such as bananas. The findings also suggest that the lack of consensus on international standards and divergent national regulations on pesticides is costly. For example, the authors estimate that if the world were to adopt a standard at a level of regulatory stringency suggested by Codex (the body charged with setting global standards in this area), in contrast with one set at the level in place in the European Union, there would be a US$5.3 billion loss in world exports.This paper - a product of Trade, Development Research Group - is part of a larger effort in the group to examine the link between trade, regulation, and development.

The protection of crops from insect pests and weeds is fundamentally a problem of ecological management. Modern pesticides used to perform such management are essential to efficient production of corn and soybean, the two most widely grown crops in the United States. What pesticides are sprayed where, when, and by whom is both shaped by and shapes ecological conditions. This dissertation consists of three essays on how American corn and soybean growers make insect and weed management decisions, and the impacts of these decisions on the environment.The first essay measures the impact of glyphosate-resistant weeds on farmers' tillage practices using field-level data from across the United States, demonstrating how selection pressure within weed populations can limit the long-term benefits of pesticide technologies. Using a two-stage, panel data econometric model, we estimate that the spread of glyphosate-resistant weeds has led to reduction in the adoption of conservation tillage by soybean growers by as much as 8.5 percentage points. Nationally, we estimate that the reduction in conservation tillage adoption due to glyphosate-resistant weeds has increased soil erosion into water ways by over 65 million metric tons and carbon emissions due to fuel consumption by 226,000 metric tons.The second essay measures the impact of farmers' pesticide use on butterfly abundance. By examining a full suite of pesticides in a single model, we account for substitution effects between products. We find neonicotinoids, the most widely used class of insecticides, have a detrimental impact on butterfly populations, both in aggregate and for prominent species such as Monarchs. Overall, our results show that changes in pesticide use between 1998 and 2014 accounted for a 9% decrease in total butterfly abundance.Finally, the third essay examines farmers' decisions to custom hire to spray insecticides rather than performing such field tasks on their own. Using a pilot choice experiment, we demonstrate how the value farmers place on timeliness when custom hiring varies according to farmer characteristics. We find risk-averse farmers are more sensitive to potential delays, while those with more developed social networks are less sensitive.
