We consider a standard pure exchange overlapping generations economy. The demographic structure consists of a new cohort of agents at each period with an economic activity extended over two successive periods. Our model incorporates durable goods that may be stored from one period to a...

The standard equivalence result on core and Walras equilibrium allocations uses a non-satiation and an interiority assumption. Konovalov introduced the rejective core for exchange economies with possibly satiated preferences and proved that there, the fuzzy rejective core coincides with the set...

We investigate an overlapping generations monetary economy in which agents'expectations depend upon backward looking predictors of the future price level.

The liquidity effect, defined as a decrease in nominal interest rates in response to a monetary expansion, is a major stylized fact of the business cycle. This paper seeks to understand under what conditions such an effect can be explained in a general equilibrium model with sticky prices and...

To implement continuous time option pricing models in which ARCH models can be used as direct or indirect approximators of stochastic volatility, we construct continuous time economies exhibiting equilibrium dynamics to which most asymmetric ARCH models converge in distribution as the sample...

In this paper we model the dynamic interaction of two types of agents, experimenters and imitators, whose behavior is characterized by simple rules of thumb. The agents repeatedly play a one-shot game in which the agent's actions are strategic substitutes.

The rhetorical perspective of science claims that scientific truths are what scientists agree is true on the basis of intellectual standards socially determined by the scientific tradition. According to that perspective, models are just rhetorical arguments used by economists in order to affect...

Two basic properties concerning the dynamic behavior of competitive equilibria of exchange economies with complete markets are derived essentially from the fact that the Walras correspondence has no knots.

This study analyses the impact of value added tax on key sectoral and macroeconomic aggregates, using a CGE model considered suitable for Nigeria. A survey of VATable Nigerian manufacturers, distributors, importers and suppliers of goods and services, organizations was conducted to gain insights...
