We evaluate the sensitivity of distance decay in individuals’ stated willingness to pay (WTP) for water quality improvements in eutrophied lakes. We extend the standard model of contingent valuation (CV) by allowing individuals to adopt a sequential evaluation process consisting of two...

This paper examines the interaction of productive efficiency, water quality and organizational type. A water quality index is constructed employing various contaminants which are then treated together with variables including organizational type as endogenous in an input distance function model....

The purpose of this review and analysis is to provide a basic understanding of the issues related to worldwide hypoxic zones and the range of economic questions sorely in need of answers. We begin by describing the causes and extent of hypoxic zones worldwide, followed by a review of the...

This paper explores how people involved in recreational fishing mitigate shellfishrelated health risks. Since self-protection activities are possible to reduce the probability of illness, they provide the basis for empirical estimation of the value of risk change. The probability of illness...
