The Pareto principle is often viewed as a mild requirement compatible with a variety of value judgements. In particular, it is generally thought that it can accommodate different degress of inequality aversion. We show that this is generally not true in time consistent intertemporal models where...

Estimating the cumulative distribution function in survey sampling is of interest on the population but also on a sub-population (domain). However, in most practical applications, sample sizes in the domains are not large enough to produce sufficiently precise estimators. Therefore, we propose...

In an international context of soaring oil prices and growing awareness of the need to combat global warming, wood would appear to be becoming increasingly competitive and desirable for our environment. France is the leading consumer of fuelwood in the EU, mainly for home consumption and for...

Using unique survey data of 10,000 households from 10 OECD countries, we identify the driving factors of household adoption of water-efficient equipment by estimating Probit models of a household's probability to invest in such equipment. The results indicate that the adoption of water-efficient...

We prove the existence of competitive equilibrium and the moothness of policy function in an optimal growth model with elastic labor supply by using a simple method. Our approach is based on the result of existence of Lagrange multipliers and their representation as a summable sequence due to Le...

This paper studies the incentives that developing countries have to enforce intellectual properties rights (IPR). On the one hand, free-riding on rich countries technology reduces the investment cost in R&D. On the other hand, it yields apotential indirect cost: a firm that violates IPR cannot...
