We try to establish which is the structure that best defines the venezuelan foreign exchange market. Asking ourselves whether there exist a group of agents able to exert market power. We assume that the flow of currency between banks follows a first order stochastic Markov process of first...

This paper presents the results of a Computable General Equilibrium model simulation built to Venezuela. The model is exemplified by the calibration and simulation of an open economy with three institutional actors (households, firms and government) and three productive sectors (oil,...

Based on a simple Markov regime switching model, this article presents evidence on the effects of macroeconomic announcements on individual stocks returns. The model specification allows two regimes to be distinguished: one with high volatility and the other with low volatility. Considering the...

This article proposes an extension of Dixit (1989, Quart. J. Econ.), assuming that potential exporting firms benefit from the experience of firms already settled in the foreign market which allows the sunk cost to diminish. In general, the numerical results show that hysteresis is lower as...

Using a Markov regime switching model, this article presents evidence on the well-known January effect on stock returns. The specification allows a distinction to be drawn between two regimes, one with high volatility and other with low volatility. We obtain a time-varying January effect that...

A domestic monopolistic firm has the option to service a foreign market through export or by setting up a plant in the host country under exchange rate uncertainty. We analyze the effect of the parameters of the demand and cost functions on hysteresis. We also show results on the effect of...

In this article I analyze the Spanish stock market in an international setting. Using a simple Markov regime switching model I get a time varying measure of the effect of the return on a Latin American portfolio on the Spanish stock returns. The evidence can be summarized as follows. First, I...
