This paper presents an experimental investigation of the three ambient-based mechanisms proposed by Segerson [J. Environ. Econom. Management 15, 87-98 (1988)] for controlling emissions from a group of nonpoint source polluters: a marginal tax/subsidy, a fixed penalty, and a mechanism that...

In this paper we build on a voluntary mechanism introduced by Segerson and Wu (2006) that uses the threat of an ambient tax to induce nonpoint source polluters to reduce emissions. In addition to reviewing Segerson and Wu's policy, we propose a new voluntary/threat policy that offers some...

This article considers whether communication can improve the efficacy of incentive mechanisms designed to correct the problem of moral hazard in groups. In particular, we use experimental economics methods to study environmental targeting instruments proposed by Segerson (1988) for regulating a...

A potential concern in “multiple bounded discrete choice” contingent valuation surveys – where the respondent is asked to express voting certainty, rather than a simple yes or no, on a large number of payment amounts (bids) – is whether responses are influenced by the particular position...

Past field validity tests of contingent valuation have relied on voluntary contribution mechanisms to elicit actual willingness to pay, and may overestimate hypothetical bias because of free riding in the actual contributions. This paper argues that provision point mechanisms are a preferred...

Can hypothetical questions reveal true values? An examination of thelaboratory experimental literature examining contingent valuation (CV)lends some support for using open-ended hypothetical willingness to payquestions. However, experimental studies examining dichotomous choicehave found that...
