We study the differentiability of order k greater than or equal to 1 of optimal trajectories of dynamic economic models with respect various parameters like initial stock, discount rate, ... We use the framework of Babach spaces of sequences and we use Differential Calculus on operators between...

We study a selection method for a Nash feedback equilibrium of a one-dimensional linear-quadratic nonzero sum game over an infinite horizon: by introducing a change in the time variable, one obtains an associated game over a finite horizon T 0 and with free terminal state. This associated game...

We modify the altruistic model by assuming that income, instead of the heir's utility, enters the altruist's utility function. We name this formulation "myopic" because, unlike in Barro's (1974) model, the altruist does not need to foresee into the indenite future to make his decisions. We...

This paper investigates necessary conditions for an equilibrium to exist on a reinsurance market with short sale constraints. It establishes that, equilibrium, there exists an equivalent probability measure under which the reinsurance premium is the compensator of the jump process describing the...

This paper aims at measuring the robustness of Real Business Cycle international stylized facts across exchange rate regimes. I thus investigate th e impact of the Bretton Woods System and the ERM on the business cycle regularities. Thanks to bootstrap techniques, I measure the accuracy of the...

When calibrated, the Mortensen & Pissarides [1994] is able to produce some stylized facts highlighted by empirical studies on US gross job flowa. However, other stylized facts concerning their asymmetric properties are generally neglected at the aggregate level. The aim of this paper is to test...

In this chapter, we derive Yaari's model of decision under risk in connection with Schmeidler's model of decision under uncertainty. The model is illustrated with two applications in insurance theory. Final comments concern the general Rank Dependent Expected Utility (RDEU) model.

In the first place, we present a quasi fixed-point theorem for a correspondence defined on some infinite-dimensional locally convex topological vector space such that some variables have open lower sections and the other ones are upper semicontinuous. In the second place, we propose a direct...
