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...

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...
