I present a model of industry dynamics resulting from competition between forward looking, heterogeneous firms that face three simultaneous challenges: learning in the process of production, competing against new entrants able to imitate best practice (albeit imperfectly), and enduring...

We investigate portfolio allocations and asset returns within a stochastic OLG economy with risky equity, generation-wide labor income shocks and portfolio nonnegativity constraints. Our model assumes a difference stationary endowment process, a young generation that faces labor income...

Papers on international business cycles have documented spurious welfare reversals: incomplete markets produce a higher level of welfare than the complete market. This paper first demonstrates how conventional linearization, as used in King, Plosser, and Rebelo (1988), can generate approximation...

In recent years the relationship between ÎmoneyÌ and the macroeconomy has assumed prominence in the academic literature and in Central Banks circles. Although some Central Bankers have stated that they have formally abandoned the notion of using monetary aggregates as indicators of the impact...

In recent years a large number of models of financial markets based on interacting heterogeneous agents have been developed. These models generally allow the size of the different groups of agents to vary according to the evolution of the financial market. Adaptive belief system proposed by...

This paper discusses how forecasts may be affected by the use of real-time data rather than latest-available data. The key issue is this: In the literature on developing forecasting models, new models are put together based on the results they yield using the data set available to the model...

This paper explores the question whether boundedly rational agents learn to behave optimally when asked to voluntarily contribute to a public good. The decision process of individuals is described by an Evolutionary Algorithm. We find that the contribution level converges towards the Nash...

The issue of quantifying the empirical relevance of the different channels of transmissions through which monetary policy exerts its influence on demand, output and prices has received wide and increasing attention in recent years. In this paper we examine under which conditions the different...

Is a fair degree of equality among economic agents with respect to income and wealth compatible with an optimal level of economic growth - or does initiatives promoting equality restrain growth, or in the opposite, does initiatives promoting growth restrain equality? These are questions that...

DYNARE: A program for the simulation of rational expectation models Michel Juillard (CEPREMAP and University Paris 8) DYNARE is a user oriented general program for the simulation of deterministic or stochastic models. For linear models, it implements a generalized Schur decomposition algorithm;...
