We show that the celebrated Atkinson and Stiglitz (1976) result on the uniformity of the commodity tax rates when preferences are weakly separable between goods and leisure does not hold when (at least) one of the goods is produced within the household. The result is restored if preferences are...

We examine the optimal time-variant refuge policy to manage pest resistance to Bt crops in afinite-horizon discrete-time model. We identify analytically the intertemporal effects of refuge fields on the pest population and its susceptibility. The shape of the optimal refuge policy and whether or...

The paper develops a framework combining a model of rational behaviour under dietary constraints, an epidemiological model of diet-related mortality, and a life-cycle-analysis model of environmental impact, which permits the ex-ante assessment of dietary recommendations in multiple...

The broad aim of this paper is to gain some insight into the quantitative importance of reputation in e-commerce. We use an exhaustive data set from one of France’s largest e-commerce platforms, <a href="http://www.priceminister.com/">PriceMinister.com </a>, to estimate a statistical causal effect of a seller’s reputation (and size)...

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;...
