A country's intertemporal budget constraint implies current account stationarity or that its saving and investment rates should cointegrate. However, such behaviour may not pertain in finite sample spans where the current account could be subject to persistent shocks. Accordingly, this paper...

This study indirectly addresses the issue of potential nonlinearities in real exchange rate adjustment for 18 OECD economies 1973-1998 using recent developments in the theory of nonparametric cointegration. While the standard Johansen tests yield mixed evidence, the results from a new...

Empirical studies have had difficulty in establishing the long-run relationship between real exchange rates and real yield differentials predicted by sticky price exchange rate models. We revisit this issue in a nonstationary panel regression framework. This facilitates estimation of a long-run...

This paper investigates the information content of the ex post overnight return for one-day-ahead equity Value-at-Risk (VaR) forecasting. To do so, we deploy a univariate VaR modeling approach that constructs the forecast at market open and, accordingly, exploits the available overnight...
