Recently, Caballi and Pomansky (1996) proposed a formal definition of mixed risk aversion and characterized stochastic dominance in presence of such utility functions. However they did not study comparative mixed risk aversion. In this note we give a sufficient condition for analytic comparative...

In this paper we show how a shift in a return distribution affects the composition of an optimal portfolio in the case of one riskless asset and two risky assets. We obtain that, in general, such a shift modifies the composition of the mutual fund. We also show that the separating conditions...

Information problems have a large role to play in insurance markets and the regulations governing these markets were in part designed to take such problems into account. Classification variables are usually the tools used to reduce adverse selection, whereas bonus-malus (or merit-rating) schemes...

In this paper, we propose an empirical analysis of the presence of adverse selection in an insurance market. We first present a theroetical model of a market with adverse selection and we introduce different issues related to transaction costs, accident costs, risk aversion and moral hazard. We...

In this paper we show how a shift in a return distribution affects the composition of an optimal portfolio in the case of one riskless asset and two risky assets. We obtain that, in general, such a shift modifies the composition of themutual fund. We also show that the separating conditions...

The goal of this article is to isolate the significant determinants that affect the decision of non-financial firms to hedge their risks. Our application is for the North American gold mining industry. The random variable considered is the selling price of an ounce of gold. We show that several...

The aim of the present paper is to propose a rational model of decision-making for lotteries. The key element of the theory is the use of cognitive processes. The maximization of the degree of confidence associated with each judgment involves different processes. Our contribution explains some...

We analyze the effect of generalized first and second order stochastic dominance changes in a returns distribution on optimal financial portfolios with two risky and a risk free assets. We show that constant relative risk aversion plays an important role in explaining how the composition of the...

In this paper we show how the order of Linear Stochastic Dominance proposed by Gollier (1995) can be applied to situations with dependent risky assets.
