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...

The economics of human development and social mobility
Heckman, James J.; Mosso, Stefano - 2014
This paper distills and extends recent research on the economics of human development and social mobility. It summarizes the evidence from diverse literatures on the importance of early life conditions in shaping multiple life skills and the evidence on critical and sensitive investment periods...

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...

Economic growth and judicial independence : cross country evidence using a new set of indicators
Feld, Lars P.; Voigt, Stefan - 2003
Rational politicians are interested in judicial independence (JI) in order to make their promises credible. But if politicians preferences deviate from the dicta of the judiciary, they also have incentives to renege on judicial independence. These two conflicting aspects are measured by two...

Making judges independent : some proposals regarding the judiciary
Feld, Lars P.; Voigt, Stefan - 2004
It is argued that an independent judiciary is a necessary condition for both individual liberty and economic prosperity. After having surveyed the literature dealing with how to arrange for an independent judiciary, the authors derive some additional policy implications by drawing on two...
