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...

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...

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...

Inequality and growth revisited
Barro, Robert J. - 2008
This paper updates and extends the work of Barro (2000). International data confirm the presence of the Kuznets curve-an inverse-U shape relationship between income inequality and per capita GDP-that is relatively stable from the 1960s into the 2000s. The direct effect of international openness...

Greasing the wheels of entrepreneurship? : the impact of regulations and corruption on firm entry
Dreher, Axel (contributor); Gassebner, Martin (contributor) - 2007
The paper investigates whether the impact of regulations on entrepreneurship depends on corruption. We first test whether regulations robustly deter firm entry into the markets. Our results show that some regulations are indeed important determinants of entrepreneurial activity. Specifically,...
