Reference prices constitute a main determinant of patient health care reimbursement in many countries. We study the effects of a change from an "external" (based on a basket of prices in other countries) to an "internal" (based on comparable domestic products) reference price system. We find...

We investigate the accuracy of ex ante assessments of vulnerability to poverty using cross-sectional data and panel data. We use long-term panel data from Germany and apply different regression models, based on household covariates and previous-year equivalence income, to classify a household as...

To explore single mothers labor market participation we analyze specific circumstances and dynamics in their life courses. We focus on the question which individual and institutional factors determine both professional advancement and professional descent. Due to dynamics in women s life course...

While the limiting null distributions of cointegration tests are invariant to a certain amount of conditional heteroskedasticity as long as global homoskedasticity conditions are fulfilled, they are certainly affected when the innovations exhibit time-varying volatility. Worse yet, distortions...

This paper uses panel data from the German Socio-Economic Panel (SOEP) to analyze welfare entry and exit among natives and immigrants after a substantial reform of the welfare system (``Hartz reform''). Using results from dynamic multinomial logit models, we calculate transition matrices between...

This paper contributes to the literature providing indirect evidence for profit shifting within multinational companies. In contrast to the previous studies we account for the tax responsiveness of the capital stock and analyse the impact of corporate taxes on both pre- and post-tax...

This paper sheds new light on the impact of information risk and market stress on herding of institutional traders from both, a theoretical and an empirical perspective. Using numerical simulations of a herd model, we show that buy and sell herding intensity should increase with information...

This paper argues that typical applications of panel unit root tests should take possible nonstationarity in the volatility process of the innovations of the panel time series into account. Nonstationarity volatility arises for instance when there are structural breaks in the innovation...

In most of the developed countries the number of low-skilled workers decreased and the number of high-skilled workers increased. However, it is far from clear whether and how this change in the skill composition of the employees affects the evolution of regional employment disparities....
