We consider a model in which the agent faces two independant risks of losswith different probabilities of occurence and (possibly) different levels of potential loss. We show that it is optimal to select a deductable for the low probability event that is not larger than the optimal deductable...

The GARCH and Stochastic Volatility paradigms are often brought into conflict as two competitive views of the appropriate conditional variance concept: conditional variance given past values of the same series or conditional variance given a larger past information (including possibly...

This paper synthesize different econometric models of the postal delivery, estimated using a french data set. These models explain the demand of labor (representing the essential part of the cost) by a vector of outputs (different types of delivered objects) and by geographical characteristics...

The paper discusses how conflicts between the multiple objectives of policymakers (efficiency, equity, fiscal, speed of reform, signaling...) can influence the optimal design of concessions contracts for network services in infrastructure. The discussion covers the relevance of information...

This paper aims at measuring the loss in the value of a firm due to the gamble for resurrection, in a standard contingent claims model. Just before a debt repayment is due, the equityholders of a levered firm can decide to shut the firm down or to keep it as an ongoing concern. We study how...

The classical price (quantity) discrimination model relies on the assumption that the consumers can neither buy more than one bundle each, nor resell the goods to each other. This assumption is lifted. In a two-type context, the consumers' set strategy is enlarged, first to allow for multiple...

An encompassing test between two models is based on the idea that the first model is able to explain the inference obtained by the second model. In a Bayesian Framework, the posterior distribution of the second model will then be compared to the posterior distribution built in hte first model...
