In this paper we consider a two periods model of cropping using irrigation. The farmer takes two kind of decisions, one related to the level of investment in irrigation capacity and the other one to the irrigation level in each period. In the first period, decisions are taken under uncertainty...

The purpose of this paper is to show that in a general equilibrium framework it is never optimal to use high cost substitute after lower cost exhaustible resource even if it is possible to accumulate productive capital. Indeed if the high cost substitute is scarce it is always optimal to consume...

This paper examines the link between pollution and income. It shows how income inequality affects environmental policies and therefore pollution. The Environmental Kuznets Curve (EKC) hypothesis proposes that there is an inverted U-shape relation between environmental degradation and income per...

We estimate the irrigation water demand for a season under uncertainty using a dynamic programming model and a crop-growth simulation model (EPIC-PHASE) linked to a CRRA utility function representing the farmer's objective function. This model is used to generate the data allowing the estimation...

The aim of this article is to investigate the explanatory variables of the number of Facebook fans and Twitter followers for professional sports clubs based on the financial value literature. Such explanatory variables are related to local market conditions and on-field and off-field...
