We examine policy instruments for ambient water quality protection. One objective is to illustrate the unique and complex informational challenges that must be addressed in constructing instruments that are effective and efficient for point and nonpoint sources. A second objective is to describe...

We consider the design of ambient taxes forrisk-neutral and risk-averse polluters whenpolluters and the regulatory agency haveasymmetric information about environmentalrelationships and probabilities associatedwith random events. Unlike prior work, we showthat under these conditions, optimal...

Research on nonpoint pollution control instruments has focused primarily on incentives applied either to production inputs that affect nonpoint pollution, or to ambient pollution concentrations. Both approaches may in theory yield an efficient solution. However, input-based incentives will...

The implementation of voluntary adoption of the Code of Conduct (CoC) to promote environmental responsibility and sustainable development of Thai shrimp industry is examined. Farmers' perceived- benefits, risks and uncertain-ties associated with the adoption and their perceived extra fixed cost...

We develop a multiple-firm model of an industry's voluntary adoption of environmental protection measures to achieve a predetermined industry-wide emissions reduction target under an explicit threat of imposition of an emissions tax. We examine the free-riding incentive of individual firms and...

This paper analyses the conditions under which a group of firms has the incentive to sign a Voluntary Agreement (VA) in order to control its emission flows even in the presence of free-riding by other firms in the industry. For the purpose of this paper it is assumed that free-riders cannot be...
