When the aim is to model market-shares as a function of explanatory variables, the marketing literature proposes some regression models which can be qualified as attraction models. They are generally derived from an aggregated version of the multinomial logit model widely used in econometrics for...

Regression models have been developed for the case where the dependent variable is a vector of shares. Some of them, from the marketing literature, are easy to interpret but they are quite simple and can only be complexified at the expense of a very large number of parameters to estimate. Other...

We study a simple influence game, in which a lobby tries to manipulate the decision of a legislature via monetary offers to one or more members. The type of a legislator is the relative weight he/she places on social welfare as compared to money. We study the equilibria of this lobbying game under...

We develop a theoretical model that describes risk-averse farmers' decisions when facing production risk due to uncertain weather conditions and when irrigation water can be traded on a market. We focus on the role of initial water allocations granted to irrigated farms at the start of the season....

Natural capital is complex to price notably because of the high uncertainties surrounding the substitutability of its future ecosystem services. We examine a two-tree Lucas economy where both the economic growth and the degree of substitutability are uncertain. We show that the uncertain...

Theoretical studies show that shocks to funding constraints should affect and be affected by market illiquidity. However, little is known about the empirical magnitude of such responses because of the intrinsic endogeneity of illiquidity shocks. This paper adopts an identification technique based...
