Test-retest studies help establish the reliability of contingent valuation (CV) responses but must confront the problem that the initial response may influence subsequent responses, and thus weaken conclusions. We develop a model that tests the influence of heterogeneous preferences and previous responses. By estimating a model of sportfishing, we show that correlation between answers to a CV question is induced by heterogeneous preferences.

The precautionary principle (PP) is fundamentally a claim that acting to avoid and/or mitigate threats of serious harm should be accorded high priority in public policy. Over the last three decades, governments and international bodies have endorsed it in principle, and some of them have incorporated it into some areas of policy practice. Yet, PP is controversial in policy circles,

Communities owning and living on ancestral land tend to have a strong sense of stewardship over the land and its resources, which may translate into an economic value to present generations of being able to pass on ancestral lands to future generations (i.e. bequest value). This study estimates bequest values to local users of a traditional fishing ground on the Coral Coast of Fiji, using a contingent valuation approach. Using monetary as well as time-based contributions, bequest values are estimated at between FJ$1.25–1.41 (US$0.64–0.73) per individual per week, or FJ$183.90 (US$106.91) per household per year. This represents a significant proportion of stated average household expenditure, comparable to spending on durable household goods, and clothes and footwear. These results suggest that low-income groups may have significant bequest values, which should be accounted for in developing-economy valuation studies.

The benefits for specific health impacts related to air and water quality were measured in simultaneous contingent valuation surveys conducted in five different European countries. Consistent inter-country differences in willingness to pay to avoid ill health episodes could not be explained by measurable differences in individual characteristics. International transfer of unit values resulted in an average transfer error of 38%. Accounting for measurable differences among countries in health status, income and other demographic measures, either through ad hoc adjustments to the transferred values or through value function transfer, did not improve transfer performance.

Abstract. A growing body of research has centered on the issue of the relationship between financial and environmental performance. The lack of consensus in this literature can be attributed to several factors. The cost of complying with environmental regulation can be significant and detrimental to shareholder wealth maximization. Conversely, a firm that can effectively control pollution might also be able to effectively control other costs of production and hence earn a higher rate of return. We utilize data from the Investor Responsibility Research Center as well as a proprietary database to investigate the relationship between environmental performance and financial performance in electric utilities. Utilities, as producers and distributors of energy, produce substantial amounts of pollution. However, since public utilities are regulated, studying the financial and environmental performance of utilities affords us the opportunity to see what role regulation plays in enhancing or...

This paper presents an optimal control model to analyze reforestations with two different species, including commercial values, carbon sequestration and biodiversity or scenic values. We discuss the implications of partial or total internalization of environmental values, showing that internalizing only carbon sequestration may have negative impacts on biodiversity-scenic values. To evaluate the practical relevance, we compare reforestations in the South-west of Spain with cork-oaks (a slow-growing native species) and with eucalyptus (a fast-growing alien species). We do the analysis with two different carbon crediting methods: the Carbon Flow Method and the Ton Year Accounting Method. With the first method, the forest surface increases more, but using mainly eucalyptus. With the second, additional reforestations are done mainly using cork-oaks. We value the impact on visitors of these reforestations using stated preferences methods showing that, when these values are internalized, cork-oaks are favored.
