The paper proposes a technique for the estimation of possibly nonlinear panel data models in the presence of heterogeneous unit nonresponse. Attrition or unit nonresponse in panel data usually renders parameter estimators inconsistent unless the unavailable information is missing completely at...

In nonparametric mean regression various methods for bandwidth choice exist. These methods can roughly be divided into plug-in methods and methods based on penalizing functions. This paper uses the approach based on penalizing functions and adapt it to nonparametric quantile regression...

We consider an optimal control problem for a one-dimensional Itô diffusion and a stochastic game of optimal stopping associated with it. Their value functions satisfy ... and an optimal control defines a saddle point for the game. This extends earlier results to the case of bounded variation...

This paper examines the impact of job search methods on the output of the job search process in a segmented labor market. Theoretical models of job search, like the widely used search approach, generally contain only one parameter capturing all possible factors affecting the efficiency of...

Regardless of the importance of growth, there are still some reasons to have a closer look at the “equity-growth-relation”. This will be shown in section 2. In some cases the issue of inequality might be neglected because it does not hinder but rather stimulate economic growth. The poor...

(Einleitung)(...) Ziel der vorliegenden Arbeit ist deshalb die Übertragung dieses Instruments auf die Entstehungsphase einer Immobilie, um die Kosten frühzeitig unter Berücksichtigung der Nutzeranforderungen zu gestalten und zu steuern. Um dabei einen engen Bezug zur praktischen Umsetzung...

We hypothesize that an individual's time use choices are contingent on the time use choices of others because the utility derived from leisure time often benefits from the presence of companionable others inside and outside the household. We develop a model of time use, and demonstrate that its...

In the context of economic instruments for more energy efficiency and climate protection, tradable certificates have been investigated for renewable energy and for a number of emissions. In contrast, tradable energy efficiency - or "white" - certificates have only lately been considered as a...

Most systems of health care financing in EU member states currently include elements of income redistribution. The paper analyzes the effects of shifting this kind of redistribution to the tax system and argues that this reform could create two types of efficiency gains. On the expenditure side,...
