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...

Are "new' donors different? : comparing the allocation of bilateral aid between non-DAC and DAC donor countries
Dreher, Axel; Nunnenkamp, Peter; Thiele, Rainer - 2010
Major DAC donors are widely criticized for weak targeting of aid, selfish aid motives and insufficient coordination. The emergence of an increasing number of new donors may further complicate the coordination of international aid efforts. On the other hand, new donors (many of which were aid...

Skill policies for Scotland
Heckman, James J. (contributor);  … - 2004
This paper argues that skill formation is a life-cycle process and develops the implications of this insight for Scottish social policy. Families are major producers of skills, and a successful policy needs to promote effective families and to supplement failing ones. We present evidence that...
