The effects of variance breaks on homogenous panel unit root tests
Herwartz, Helmut; Siedenburg, Florian - 2009
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...

State dependence in the finance-growth nexus : a functional coefficient approach
Herwartz, Helmut; Yabibal Mulualem Walle - 2013
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...

A new approach to bootstrap inference in functional coefficient models
Herwartz, Helmut (contributor); Fang, Xu (contributor) - 2007
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...

How global is FDI? : evidence from the analysis of Theil indices
Bickenbach, Frank; Liu, Wan-hsin; Nunnenkamp, Peter - 2015
It is open to question whether the intensified worldwide competition for FDI has reduced its traditionally strong concentration in a few large and relatively advanced host countries. We calculate and decompose Theil indices to track changes in absolute and relative concentration of FDI during...

Dissecting the PPP puzzle : the unconventional roles of nominal exchange rate and price adjustment
Cheung, Yin-Wong; Lai, Kon-sun; Bergman, Michael U. - 2003
The conventional view, as expounded by sticky-price models, is that price adjustment determines the PPP reversion rate. This study examines the mechanism by which PPP deviations are corrected. Nominal exchange rate adjustment, not price adjustment, is shown to be the key engine governing the...

On cross-country differences in the persistence of real exchange rates
Cheung, Yin-Wong; Lai, Kon-sun - 1999
Previous findings of long-run purchasing power parity come mainly from data for industrial countries, raising the issue of whether the results suffer sample-selection bias and exaggerate the general relevance of parity reversion. This study uncovers substantial cross-country heterogeneity in the...
