In this paper we analyze the asymptotic properties of the popular distribution tail index estimator by B. Hill (1975) for possibly heavy- tailed, heterogenous, dependent processes. We prove the Hill estimator is weakly consistent for processes with extremes that form mixingale sequences, and...

In this paper, we develop a parametric test procedure for multiple horizon "Granger" causality and apply the procedure to the well established problem of determining causal patterns in aggregate monthly U.S. money and output. As opposed to most papers in the parametric causality literature, we...

The universal method for testing linearity against smooth transition autoregressive (STAR) alternatives is the linearization of the STAR model around the null nuisance parameter value, and performing F-tests on polynomial regressions in the spirit of the RESET test. Polynomial regressors,...

An attempt to quantify possible negative effects of external crises in emerging market economies is made in this paper. The direct and indirect effects of the external crises, here sudden stops in capital flows and currency crises, are estimated and compounded into composite overall effects. In...

According to economic theory, the capital inflows reversal – so-called sudden stop – has a significant negative effect on economic growth. This paper investigates the direct impact of current account reversals on growth in Central and Eastern European countries. Two steps to conduct the...

This paper attempts to carry out a study of relative importance of anticipated and unanticipated external crises for the dynamics of economic growth. The estimations are carried out within a two equation system capturing the possibility of a common shock to external crises and growth. The effect...
