Spatial models of voting have dominated mathematical political theory since the seminal work of Downs. The Downsian model assumes that each elector votes on the basis of his utility function which depends only on the distance between his preferred policy platform and the ones proposed by...

Public economics proposed various models that intend to determine the optimal provision of public goods based on individual preferences. To provide decision makers with empirical recommendations, economists thus need to elicit individual preferences, and more precisely the marginal rate of...

This article addresses the important issue of anchoring in contingent valuation surveys that use the double-bounded elicitation format. Anchoring occurs when responses to the follow-up dichotomous choice valuation question are influenced by the bid presented in the initial dichotomous choice...

In this article, we propose a unified framework that accomodates many of the existing models for dichotomous choice contingent valuation with follow-up and allows to discriminate between them by simple parametric tests of hypothese. Our empirical results show that the Range model, developped in...

In this paper, we study starting point bias in double-bounded contingent valuation surveys. This phenomenon arise in applications that use multiple valuation questions. Indeed, response to follow-up valuation questions may be influenced by the bid proposed in the initial valuation question....

In this article, we develop a dichotomous choice model with follow-up questions that describes the willingness to pay being uncertain in an interval. The initial response is subject to starting point bias. Our model provides an alternative interpretation of the starting point bias in the...

La théorie économique propose un certains nombre de modèles qui visent à déterminer le montant optimal de bien public à produire sur la base des utilités individuelles. Pour avoir une portée pratique, ces modèles nécessitent de connaître le taux marginal de substitution entre bien...

Since they have been increasingly used in economics, elicitation rules for subjective beliefs are under scrutiny. In this paper, we propose an experimental design to compare the performance of such rules. Contrary to previous works in which elicited beliefs are compared to an objective...

Surveys are sometimes viewed with suspicion when used to provide economic values, since they are sensitive to framing effects. However, the extent to which those effects may vary between individuals has received little attention. Are some individuals less sensitive to framing effects than...

This paper explores a two-candidate spatial voting model, where one candidate has a valence advantage. Contrary to previous models, we introduce a multiplicative advantage, rather than an additive one. This takes into account the possible interaction between the quality of a candidate and his...
