Using data from 1995 and 1996, we estimate the cost of the Arizona Enhanced I/M Program and the emission reductions achieved. We begin by enumerating briefly the components of I/M costs and discuss their size and incidence. Then we describe the empirical information from Arizona and how we use...

The expense and inconvenience of enhanced vehicle emissions testing using the full 240-second dynamometer test has led states to search for ways to shorten the test process. In fact, all states that currently use the IM240 allow some type of fast-pass, usually as early in the test as second 31,...

Many of the biggest environmental policies are federal: the Clean Air Act, the Clean Water Act, and so forth. Yet those federal laws leave important niches to be filled by state authorities; there are areas of environmental policy in which state governments can and should take the lead. Some...

The dominant paradigm of conservation-reserve planning in economics is to optimize the provision of physical conservation benefits (measured in units like species protected) given a budget constraint. Large-scale biology-based priority setting implies that the value we place on biodiversity and...

In many parts of the world, deteriorating environmental conditions have led policy makers to develop policies and programs aimed at promoting conservation practices on lands devoted to agriculture. Such programs have been studied by environmental economists, but little research has been done on...

Current climate policy focuses disproportionately on carbon dioxide emissions but recent developments have begun to recognize the important role of other gases, including methane. As a result, anaerobic digesters (ADs) on dairy farms present an opportunity to reduce greenhouse gas emissions. We...

This paper evaluates the effects of annual fluctuations in temperature and precipitation on labor allocation in rural Mexico. We use a 28-year panel of individuals to investigate how people adjust their sector and location of work in response to year-to-year variation in weather. Controlling for...

To capitalize on potential opportunities presented by growing consumer demand for locally grown foods, farmers need insight into significant motivations and behavioral characteristics of consumers in their region. This article aims to evaluate the characteristics of southeastern urban consumers...
