We study cycles and chaos in economic models. Autonomous dynamical systems are considered through infinite time horizon optimization models. We first show how endogenous fluctuations arise in a multisector growth model. Secondly, we consider an extension of this model by allowing direct...

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 consider a capital accumulation game between two different jurisdictions. When the jurisdictions adopt open loop strategies, we study the inefficiency of the steady state Nash equilibrium with respect to the steady state utilitarian solution.

We consider an overlapping generations model of small open economy with Harrod neutral technical progress. If the interest rate is less that the growth rate, intergenerational public transfers increase welfare of some generations and reduce welfare of others.

We show that the empirical process of the squared residuals of an ARCH(p) sequence converges in distribution to a Gaussian process B (F(t)) + tf(t)E , where F is the distribution function of the squared innovations, f its derivative, {B(t), 0= t = 1} a Brownian bridge and E a normal random...

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...

We consider an overlapping generations model with endogenous labor supply. Individuals live for two periods and have different skills. We state equivalence properties of different transfer policies, assuming the government cannot identify individuals and has a limited range of instruments that...

This paper proposes a new kind of asymmetric GARCh where the conditional variance obeys two different regimes with a smooth transition function. In one formulation variance reacts differently to negative and positive shocks while a second formulation, small and big shocks have separate effects.

This paper studies relationships between the determinacy of a stationary equilibrium in the perfect foresight dynamics, and its local stability in dynamics arising from econometric learning procedures. There is no clear links in linear scalar economies where agents forecast only one perods...
