The goal of this paper is to assess the academic literature written between the Exxon spill and the BP disaster in order to shed light on the fundamental question of validity of the contingent valuation, and more generally, stated preference methods. The fundamental question is straightforward:...

In this paper we examine the performance of nested logit models in the face of two specification errors. The first specification error arises when a nested logit model is appropriate, but the wrong nesting structure is chosen. The second specification error occurs when the underlying stochastic...

Global conditions under which nested logit models are consistent with utility maximization are provided by Daly and Zachary and by McFadden. Recently, Borsch-Supan and Herriges and Kling have provided conditions under which a nested logit model is locally consistent. However, previous work has...

The paper presents two simple models of dynamic consumer behavior, both taking into consideration the implications for welfare measurement when agents can delay transactions while obtaining additional information. One model studies the effect when a purchased good is non-perishable and can be...

We study the optimal emission standards under uncertain pollution damages and transaction costs associated with policy changes in a dynamic setting. We consider three alternative forms of transactions costs and show that they can lead to different kinds of delays of policy changes or smaller...
