This paper shows that the Mexican experience from 1945 to 2002 is, like the German hyperinflation period, a unique monetary ``natural experiment,'' where fundamental relationships, like money demand, PPP and the monetary model of exchange rate determination can be analyzed with unparalleled...

We propose a general non-linear simultaneous equations framework for the econometric analysis of models of intervention in foreign exchange markets by central banks in response to deviations of exchange rates from possibly time-varying target levels. We consider efficient estimation of possibly...

In this paper we consider different periodic extensions of regression models with autoregressive fractionally integrated moving average disturbances for the analysis of daily spot prices of electricity. We show that day-of-the-week periodicity and long memory are important determinants for the...

This paper studies a plausible connection among rational speculators, exchange rate volatility and capital controls. When Krugman (1999) asserted that there should be appropriate controls on international capital movements to avoid currency volatilities from speculative activities, this paper...

The purpose of this paper is to investigate the impact of exchange rate volatility on exports among 14 Asia Pacific countries, where various measures to raise the intra-region trade are being implemented. The empirical tests using annual data for the period from 1980 to 2002 detect a significant...

Looking closely at the PPP argument, it states that the currencies purchasing power should not change when comparing the same basket goods across countries, and these goods should all be tradable. Hence, if PPP is valid at all, it should be captured by the relative price indices that best fits...

Empirical evidence against both risk-sharing across countries and the uncovered interest rate parity (UIP) condition have been extensively documented. This paper investigates the empirical implications of imperfectly integrated financial markets resulting from these two issues. Under this asset...
