This paper considers estimation methods and inference for linear dynamic panel data models with unit-specific heterogeneity and a short time dimension. In particular, we focus on the identification of the coefficients of time-invariant variables in a dynamic version of the Hausman and Taylor...

This paper provides an empirical analysis of reference-dependent effects of unemployment on mental health. I show that the negative effect of unemployment on mental health depends on expectations about the future employment status. Several contributions to the literature have shown that the...

This study attempted to analyze the effect of regulation and political stability in allocation of mobile telecommunication investments in the African continent between year 2001 and 2011. In order to better understand the dynamics of investment in telecommunications, a framework was developed to...

This paper deals with the relationship between the traditional fixed-line, mobile and Voice over IP telephony in the EU.We estimate the supply and demand for fixed-line telephony using data on 25 EU member states for the 2006:Q2 - 2011:Q4 period. Employing instrumental variable approach, we...

Compared to other European countries rental apartments dominate the German housing market. Policymakers and a large part of the population alike worry about the amount of affordable living space. Especially in metropolitan areas a high demand for living space exists and has been leading to a...

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....

We study state dependence in the German welfare system and compare transition patterns before and after recent reforms of the welfare system (Hartz Reforms). Using data from the German Socio-Economic Panel, we apply dynamic multinomial logit estimators and find that welfare transitions have...
