In this paper we apply to multiplicative lotteries the idea of preference for "harm disaggregation" that was used for additive lotteries in order to interpret the signs of successive derivatives of a utility function. In this way, we can explain in general terms why the values of the...

Many papers in the litterature have adopted the expected utility paradigm to analyze insurancedecisions. Insurance companies manage policies by growing, by adding independent risks.Even if adding risks generally ultimately decreases the probability of insolvency, the impacton the insurer's...

In this paper, we consider a décision-maker facing a financial risk flanked by a backgroundrisk, possibly non-financial, such as health or environmental risk. A decision has to be madeabout the amount of an investment (in the financial dimension) resulting in a future benefiteither in the same...

In this paper, we present a model of endogenous vertical integration and horizontal differentiation. Thereexists two output brands and two versions of the input. The only mean for output differentiation is the inputversion used in output production. Firms may choose to vertically integrate to...

We propose a new dynamic model for volatility and dependence in high dimensions, that allows for departuresfrom the normal distribution, both in the marginals and in the dependence. The dependence is modeled with adynamic canonical vine copula, which can be decomposed into a cascade of bivariate...

In a setting of R&D co-opetition we study, by using an all-pay auction approach, howcollaboration affects strategic decisions during a patent contest, and how the latter influences thepossible collaboration network structures the firms can hope to form. The all pay auctionapproach allows us to...

We study the impact of transfer pricing rules on sales prices, firms’ organizational structure, andconsumers’ utility within a two-country monopolistic competition model featuring source-basedprofit taxes that differ across countries. Firms can either become multinationals, i.e., they serve...
