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...

An empirical study on causes and consequences of inflation and inflation uncertainty
Hartmann, Matthias - 2012
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.

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...

Simple nonparametric estimators for the bid-ask spread in the Roll model
Chen, Xiahong; Linton, Oliver; Schneeberger, Stefan; … - 2016
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...

Class-size effects in school systems around the world : evidence from between-grade variation in TIMSS
Woessmann, Ludger; West, Martin R. - 2002
We estimate the effect of class size on student performance in 18 countries, combining school fixed effects and instrumental variables to identify random class-size variation between two adjacent grades within individual schools. Conventional estimates of class-size effects are shown to be...
