We model a country's de jure exchange rate policy as the choice from a multinomial logit response conditioned on the volatility of its bilateral exchange rate, the volatility of its international reserves, and the volatility of its effective exchange rate. The category with the highest...

This paper estimates UIP slope parameters using a large number of cross-country bilateral exchange rates from a broad spectrum of developed and developing countries. Empirical evidence shows that short-term (one month) UIP holds well, and the failure of UIP is largely due to the key currency...

We propose an econometric procedure for obtaining de facto exchange rate regime classifications which we apply to study the relationship between exchange rate regimes and economic growth. Our classification method models the de jure regimes as outcomes of a multinomial logit choice problem...

This paper proposes a new test statistic to deter the presence of heteroskedasticity. The proposed test does not require a parametric specification of the mean regression function in the first stage regression. The regression function is estimated nonparametrically by the kernel estimation...

This paper examines the vertical integration issue of the electricity industry. This industry is typically vertically integrated and heavily regulated. The paper investigates the potential technological efficiency loss due to the vertical disintegration using the translog production function....
