We study a nonexclusive insurance market with adverse selection in which insurers compete through simple contract offers. Multiple contracting endogenously emerges in equilibrium. Different layers of coverage are priced fairly according to the types of insurees who purchase them, giving rise to...

This paper discusses the feasibility and performances of simple mechanisms to implement international environmental agreements in the multilateral externalities context of global warming. Asymmetric information and voluntary participation by sovereign and heterogenous countries are key...

Weitzman (1998, 2001) proposed a simple “gamma discounting” method to characterize the term structure of discount rates today from the sole distribution of future spot interest rates. This rule which justifies using a smaller discount rate for longer maturities is now used for long-term...

Testosterone administration appears to make individuals less trusting, and this effect was interpreted as an adaptive adjustment of social suspicion, that improved the accuracy of trusting decisions. Here we consider another possibility, namely that testosterone increases the subjective cost of...

In this study we estimate the demand for peace and quiet, and thus also the willingness to pay for railway noise abatement, based on both steps of the hedonic model regression on property prices. The estimated demand relationship suggests welfare gains for a 1 dB reduction of railway noise as;...

Nous exploitons dans cet article la théeorie des indices de pouvoir pour éevaluer les infuences respectives des deux classes d’électeurs dans le mode de scrutin instauré par la loi électorale du 29 juin 1820, dite loi du \double vote". Nous montrons, à l’aide d’un modèle simplifié,...

We address the problem of prediction in the classical spatial autoregressive lag model for areal data. In contrast with the spatial econometrics literature, the geostatistical literature has devoted much attention to prediction using the Best Linear Unbiased Prediction approach. From the...

Agro-environmental schemes (AES), which pay farmers to adopt greener practices, are increasingly important components of environmental and agricultural policies both in the US and the EU. Here we study the French implementation of the EU AES program. We estimate additional and windfall effects...

This paper addresses the issue of price signaling in a model of vertical relationship between a manufacturer and a retailer who share the same information about quality, unlike consumers who do not observe it a priori. We show that delegating the price setting task to a retailer and controlling...

EU regulation on quality food products (PDO labeling) is expected to sustain competitiveness within the agricultural sector. This paper examines the impact of this policy on the survival of cheese firms over the period 1990-2006 in France. We show that such a policy (Appellation d'Origine...
