In this paper, I develop a new identification method to solve the problem of simultaneous equations, based on heteroskedasticity of the structural shocks. I show that if the heteroskedasticity can be described as a two-regime process, then the system is just identified under relatively weak...

In this paper I offer an alternative identification assumption that allows one to test for changing patterns regarding the international propagation of shocks when endogenous variables, omitted variables, and heteroskedasticity are present in the data. Using this methodology, I demonstrate that...

During the last two decades, many Latin American countries engaged in disinflation programs based on both exchange rate management and fiscal reforms. However, in most instances, part of the fiscal reform was delayed or not implemented completely, so the fiscal deficit increased and the program...

Mexico was upgraded from non-investment to investment grade in March of 2000. This paper examines the impact of this event on the properties of the transmission of shocks between Argentina and Mexico. The paper shows that there is a statistically significant change in the propagation of shocks...

The empirical literature on contagion has mainly measured the propagation of shocks across countries using daily stock markets, interest rates, and exchange rates. Several methodologies have been used for this purpose, however, the properties of the data introduces important limitations on the...

This paper develops a model of the circumstances under which it is beneficial to participate in a currency area. The proposed two-country monetary model of trade with nominal rigidities encompasses the real and monetary arguments suggested by the optimum currency area literature: correlation of...
