This paper suggests that IV estimators, utilizing irrelevant but persistent instruments mai produce reliable inferences, in small samples, in cases where the endogenous variables contaii autoregressive roots near unity. In such cases, these estimators appear to outperform IV estimator: with...

This paper employs a new methodology for measuring the contribution of growth and interest rate differentials to the half-life of deviations from Purchasing Power Parity (PPP). Our method is based on directly comparing the impulse response function of a VAR model, where the real exchange rate is...

In this paper we reexamine the linkages between output growth and real stock price changes for the G7 countries using a battery of non-parametric procedures to account for the impact of long-lagged observations. We find that correlation between growth and returns is detected at larger horizons...

This paper investigates the Purchasing Power Parity Puzzle in the context of a Vector Autoregressive(VAR) model, where the real exchange rate is Granger caused by macroeconomic variables, suggested by 'sticky-price' theories of exchange rate determination. By doing this, we are able to discern...

This paper evaluates the Morningstar mutual fund ranking system. We find that indeed higher Morningstar ratings are associated with higher returns on the portfolios including respectively five-, four-, three-, two- and one-star funds only (STAR5 to STAR1). We then perform an unconditional and...
