Construct validity is concerned with the consistency of empirical measures with theoretical relationships. This paper reviews and extends the theoretical relationship between averting costs and willingness to pay. Measures of these two theoretical constructs with empirical averting costs savings...

Economic instruments can achieve environmental goals at least cost and provide incentives for further improvements. There are limited opportunities for the use of such instruments in agriculture where the pollution problems can be traced as in the case of intensive livestock operations. However,...

The study explores the implications of climate change for the economic costs of ecological conservation and restoration of submerged aquatic vegetation. It develops a methodological framework that addresses the key issues of uncertainty, irreversibility and space in climate change and...

An important issue for the stated choice method is the effect of the number of choice sets on responses. Based on a study of this issue in a mailed survey, results indicate that the number of choice sets does not affect survey response rates or item non-response rates.

Agricultural agencies have long offered agri-environmental payments that are inadequate to achieve water quality goals, and many state water quality agencies are considering point-nonpoint trading to achieve the needed pollution reductions. This analysis considers both targeted and nontargeted...

Following Weitzman (1974), there is ample theoretical literature indicating that choice of pollution control instruments under conditions of uncertainty will affect the expected net benefits that can be realized from environmental protection. However, there is little empirical research on the ex...

There is considerable interest in watershed-based pollution water quality protection but the approach can be highly information intensive (USEPA 2004, NRC 2000). This study examines the value of different types and levels of information for water quality management in the Conestoga watershed....

The failure to allow for significant crop quality effects in a partial-equilibrium model can lead to misleading inferences about the price, output and welfare implications of air quality improvements. It has been observed that air pollutants such as ozone, sulphur dioxide, and nitrogen dioxide...
