.Knowledge and projection of farm numbers and the structure of their population is an important issue for agricultural economists and policy makers. Although Markov chain models have enjoyed decades of popularity in forecasting total farm numbers, they generally fail to provide a detailed...

We develop a model of trade with imperfect competition to study the welfare implications in developing and developed countries of the asymmetry in attitudes towards foreign products.

A usual explanation to low levels of contribution to public goods is the fear of getting the sucker’s payoff (cooperation by the participant and defection by the other players). In order to disentangle the effect of this fear from other motives, we design a public good game where people have...

We investigate whether an aging population may challenge the supremacy of large working-cities.

Individuals are geographically mobile...

The objective of the paper is to assess the effects of spatial agglomeration on the technical efficiency of French pig farms. We use a two-stage method with the first stage consisting of calculating the efficiency scores of pig activity with the non-parametric Data Envelopment Analysis (DEA)...

The econometric estimation of zero censored demand system faces major difficulties. The virtual price approach pioneered by Lee and Pitt (1986) in an econometric framework is theoretically consistent but empirically feasible only for homothetic demand system. It may even fail to converge...

[paper in French] Wild-boar can be considered both as a resource and as a pest. It causes collective damages and is also valued resource for recreative activity as hunting. The paper treats the economy of controlling a hunting game. A bio-economic model is presented and used for the analysis....
