This note proves existence of a unique equilibrium in a Lucas (1978) economy when the utility function displays constant relative risk aversion and log dividends follow a normally distributed AR(1) process with positive auto-correlation. In particular, the note provides restrictions on the...

In this paper we study the existence of bubbles for pricing equilibria in a pure Exchange Economy a la Lucas, with infinitely lived homogeneous agents. The model is analyzed under fairly general assumptions: no restrictions either on the stochastic process governing dividends' distribution or on...

We introduce differential information in the asset market model studied by Cheng (1991), Dana and Le Van and Le Van and Truong Xuan (2001). We prove an equilibrium existence result assuming that the economy's information structure satisfies the conditional independence property. If private...

After taking into account positive transaction costs via tackling static nonlinear programming with dynamic programming, this paper reaches three main conclusions: 1) The aggregate excess demand function of each market will be discontinuous at many price points, but the transfiguration of the...

In this paper, I study the existence and uniqueness of recursive equilibria in economies with aggregate and idiosyncratic risk. Rather than relying on compactness to establish existence, I exploit the monotonicity property of the equilibrium model and rely on arguments from convex analysis. This...

This paper studies production economies having a locally convex topological vector commodity space ordered by a closed and generating convex come such that the order intervals are topologically bounded. The generally assumed lattice properties on the commodity-price duality are replaced by an...

We prove the existence of competitive equilibrium in a single-sector dynamic economy with heterogeneous agents and elastic labor supply. The method of proof relies on exploiting the existence of Lagrange multipliers in infinite dimensional spaces and the link between Pareto-optima and...

We introduce differential information in the asset market model studied by Cheng (1991), Dana and Le Van (1996)and Le Van and Truong Xuan (2001). An equilibrium existence result is proven assuming that the economy's information structure satisfies the conditional independency property.

How do financial markets respond to firms' efforts at innovation ? To answer this question, we mesure innovation by creating a synthetic indicator based on a firm's recent history of R&D expenditure and patent applications. We focus on four 2-digit "complex technology" manufacturing sectors that...

This paper studies a simple stochastic two-period general equilibrium model with money, an incomplete market of nominal assets, and a competitive banking system, intermediate between consumers and a Central Bank. There is a finite number of agents, consumers and banks. Default is not permitted....
