East Germany´s Wage Gap : A non-parametric decomposition based on establishment characteristics

Görzig, Bernd; Gornig, Martin; Werwatz, Axel - Sonderforschungsbereich Ökonomisches Risiko <Berlin>

East German wages have been below the West German wage level since unification. Moreover, the East-West wage gap … terms of effective wages. This paper looks at the role of establishment-specific factors - such as sectoral affiliation and …

Does temporary agency work provide a stepping stone to regular employment?

Kvasnicka, Michael - 2005

Based on administrative data from the federal employment office in Germany, we apply matching techniques to estimate the stepping-stone function of temporary agency work for the unemployed, i.e. its short-run and long-run effects on their future employment prospects. Our results show that...

East Germany's wage gap: A non-parametric decomposition based on establishment characteristics

Görzig, Bernd; Gornig, Martin; Werwatz, Axel - 2006

East German wages have been below the West German wage level since unification. Moreover, the East-West wage gap … implied by the contractual wages specified in collective wage agreements is drifting ever further apart from the wage gap in … terms of effective wages. This paper looks at the role of establishment-specific factors - such as sectoral affiliation and …

Partial linear quantile regression and bootstrap confidence bands

Härdle, Wolfgang Karl; Ritov, Ya'acov; Song, Song - 2010

In this paper uniform confidence bands are constructed for nonparametric quantile estimates of regression functions. The method is based on the bootstrap, where resampling is done from a suitably estimated empirical density function (edf) for residuals. It is known that the approximation error...

Uniform confidence bands for pricing kernels

Härdle, Wolfgang Karl; Okhrin, Yarema; Wang, Weining - 2010

Pricing kernels implicit in option prices play a key role in assessing the risk aversion over equity returns. We deal with nonparametric estimation of the pricing kernel (Empirical Pricing Kernel) given by the ratio of the risk-neutral density estimator and the subjective density estimator. The...

The stochastic fluctuation of the quantile regression curve

Härdle, Wolfgang Karl; Song, Song - 2008

Let (X1, Y1), . . ., (Xn, Yn) be i.i.d. rvs and let l(x) be the unknown p-quantile regression curve of Y on X. A quantile-smoother ln(x) is a localised, nonlinear estimator of l(x). The strong uniform consistency rate is established under general conditions. In many applications it is necessary...

Increasing weather risk: Fact of fiction?

Wang, Weining; Bobojonov, Ihtiyor; Härdle, Wolfgang Karl; … - 2011

It is an undisputed fact that weather risk increases over time due to climate change. However, qualification of this statement with regard to the type of weather risk and geographical location is needed. We investigate the application of novel statistical tools for assessing changes in weather...

Mean volatility regressions

Lin, Lu; Li, Feng; Zhu, Lixing; Härdle, Wolfgang Karl - 2010

Motivated by increment process modeling for two correlated random and non-random systems from a discrete-time asset pricing with both risk free asset and risky security, we propose a class of semiparametric regressions for a combination of a non-random and a random system. Unlike classical...

Local quantile regression

Härdle, Wolfgang Karl; Spokoiny, Vladimir; Wang, Weining - 2010

Conditional quantile curves provide a comprehensive picture of a response contingent on explanatory variables. Quantile regression is a technique to estimate such curves. In a flexible modeling framework, a specific form of the quantile is not a priori fixed. Indeed, the majority of applications...

A confidence corridor for expectile functions

Duran, Esra Akdeniz; Guo, Mengmeng; Härdle, Wolfgang Karl - 2010

Let (X1, Y1), ..., (Xn, Yn) be i.i.d. rvs and let v(x) be the unknown T-expectile regression curve of Y conditional on X. An expectile-smoother vn(x) is a localized, nonlinear estimator of v(x). The strong uniform consistency rate is established under general conditions. In many applications it...
