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...

Time varying hierarchical archimedean copulae
Härdle, Wolfgang; Okhrin, Ostap; Okhrin, Yarema - 2010
There is increasing demand for models of time-varying and non-Gaussian dependencies for mul- tivariate time-series. Available models suffer from the curse of dimensionality or restrictive assumptions on the parameters and the distribution. A promising class of models are the hierarchical...

International capital market integration, educational choice and economic growth
Egger, Hartmut; Egger, Peter; Falkinger, Josef; … - 2005
This paper examines the impact of capital market integration (CMI) on higher education and economic growth. We take into account that participation in higher education is noncompulsory and depends on individual choice. Integration increases (decreases) the incentives to participate in higher...

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 determinants of trade costs : a random coefficients approach
Egger, Peter; Průša, Jan - 2014
This paper assesses whether the sensitivity of bilateral trade volumes to various trade cost factors is constant or varies across countries. It utilizes a random coeffcients model and analyses a cross-sectional sample of bilateral trade data for 96 countries in 2005. We expect the elasticity of...

What determines the finance-growth nexus? : an endogenous growth model and empirical evidence
Graff, Michael; Karmann, Alexander - 2003 - Revised version - September 2003
An endogenous growth model with a financial sector is formulated, and empirical analyses are conducted. The model exhibits structural shifts and breaks caused by institutional change, suggesting that a linear approach is inadequate. To address this point empirically, we fit data for 90 countries...

Does financial activity cause economic growth?
Graff, Michael; Karmann, Alexander - 2001 - Revised 1.2.2001
To clarify the causal links between financial activity and economic growth, three theoretical models are analyzed and a structural equation path models is estimated. In the modeling part, poverty traps result from large fixed costs or high proportions of real investment to run a financial...
