The globalization of international financial markets has renewed interest in the measurement of capital mobility. Consumption-based tests such as the Euler equation test are commonly used. These tests, however, are derived under restrictive assumptions on consumer behavior. In this paper, we ask...

The debate on the risks and benefits of the globalisation of international capital markets has focused on the volume and the volatility of the main capital flows ? foreign direct investment (FDI), portfolio investment, and foreign bank lending. Financial transfers in the form of worker...

Noting that many economic variables display occasional shifts in their second order moments, we investigate the performance of homogenous panel unit root tests in the presence of permanent volatility shifts. It is shown that in this case, panel unit root tests derived under time invariant...

In diesem Beitrag wird analysiert, ob Wechselkursprognosen Anhaltspunkte dafür liefern, dass Prognostiker ein so genanntes Herdenverhalten zeigen. Auf der Basis unterschiedlicher theoretischer Modellansätze wird skizziert, warum Prognostiker einen Anreiz haben könnten, einem Herdentrieb zu...

Empirical study of causality between inflation, inflation uncertainty and other macroeconomicy quantities. Additionally, the issue of how to measure the unobservable inflation uncertainty is addressed.

Noting that "one size does not fit all" in the case of the finance-growth (FG) nexus, a growing body of literature has recently focused on uncovering economic conditions under which financial development could be beneficial (detrimental) to economic development. We look into these conditions by...

There is increasing demand for models of time-varying and non-Gaussian dependencies for mul- tivariate time-series. Available models suffer from the curse of dimensionality or restrictive assumptions on the parameters and the distribution. A promising class of models are the hierarchical...

We introduce a new, factor based bootstrap approach which is robust under heteroskedastic error terms for inference in functional coefficient models. Modeling the functional coefficient parametrically, the bootstrap approximation of an F statistic is shown to hold asymptotically. In simulation...

We propose new methods for estimating the bid-ask spread from observed transaction prices alone. Our methods are based on the empirical characteristic function instead of the sample autocovariance function like the method of Roll (1984). As in Roll (1984), we have a closed form expression for...
