This paper examines whether deviations from PPP are stationary in the presence of nonlinearity, and whether the adjustment toward PPP is symmetric from above and below. Using alternative nonlinear models, our results support mean reversion and asymmetric adjustment dynamics. We find differences...

A stochastic volatility model where volatility was driven solely by a latent variable called news was estimated for three stock indices. A Markov chain Monte Carlo algorithm was used for estimating Bayesian parameters and filtering volatilities. Volatility persistence being close to one was...

The IMF's Consultative Group on Exchange Rate issues (CGER) has been conducting exchange rate assessments as part of the surveillance process since 1997. This paper evaluates CGER assessments from 1997 to 2006, by comparing these to subsequent movements in real effective exchange rates (REER)....

This paper assesses the extent to which crashes in emerging market currencies are predictable using simple logit models based on lagged macroeconomic and financial data. To evaluate our model, we calculate trading strategies in which an investor goes long or short in the currency depending on...

This paper addresses the issue of the appropriate exchange rate regimes for Jordan and Lebanon in the context of the literature on optimum currency areas and the arguments concerning the use of the exchange rate as a nominal anchor for the economy. It presents some empirical results on the...

The paper looks at the hypothesis that financial market liberalization can create a basis for more stable exchange rates, as deviations of exchange rates from equilibrium levels bring forth stabilizing flows of liquidity. This "endogenous liquidity" hypothesis suggests that opening financial...
