A Selection Model for Panel Data: The Prospects of Green Party Support

Although sample selection bias is a frequent problem of applied research, there has been no generalization of sample selection models with binary dependent variables of interest to data with temporal error correlations. We suggest a generalized estimating equation approach to panel data selection models, considering binary responses in both equations. We demonstrate the utility of this model by a simulation ...

A Multi-state Model of State Dependence in Labor Supply: Intertemporal Labor Supply Effects of a Shift from Joint to Individual Taxation

In this paper I develop an intertemporal discrete choice model of female labor supply to analyze the effects of true state dependence and its effect on labor supply behavior over time. The estimation results show that state dependence is significantly positive at the extensive margin and lower but in general still significant at the intensive margin. I apply this model to study the short and long run ...

Natural Gas Vehicles: An Option for Europe

In Europe natural gas vehicles play a minor role. A decisive reason for this is the dependence of most European countries from gas imports. Except for Italy, there is no tradition to use natural gas as fuel. In addition, there is a lack of infrastructure (e.g. fuelling stations). In contrast to Europe, in Latin American and Asian countries natural gas vehicles are widespread. Some countries foster ...

Climate Change and Modelling of Extreme Temperatures in Switzerland

This study models maximum temperatures in Switzerland monitored in twelve locations using the generalised extreme value (GEV) distribution. The parameters of the GEV distribution are determined within a Bayesian framework. We find that the parameters of the underlying distribution underwent a substantial change in the beginning of the 1980s. This change is characterised by an increase both in the level ...

Credit for What? Informal Credit as a Coping Strategy of Market Women in Northern Ghana

This paper explores the use of informal credit as a strategy for managing risks by market women in northern Ghana. A broad concept of the costs of risk management strategies is introduced and encompasses both a time and monetary dimension. Based on qualitative data, the analysis reveals that market women invest a considerable amount of time in maintaining complex networks of informal credit providers ...

The Spill-over Effects of Conflict on Economic Growth in Neighbouring Countries in Africa

In this article, the influence of conflict on the economies of neighbouring countries is discussed. The results from previous papers show a strong negative effect for an entire area around a country suffering from conflict, but this paper reaches a different conclusion, by using more recent data and adjusting the methodology previously employed. Additionally, a new type of contiguity matrix is constructed ...

Poverty during Transition: Household Survey Evidence from Ukraine

The paper analyzes the incidence, the severity and the correlates of household poverty in Ukraine during transition using two comparable surveys from 1996 and 2004. We measure poverty using income and consumption and various poverty lines. Poverty estimates are higher than previously reported if controlling for transition-related labor market shocks. Poverty in both periods follows some of the correlates ...

The Impact of Risk Attitudes on Entrepreneurial Survival

Risk attitudes influence the complete life cycle of entrepreneurs. Whereas recent research underpins the theoretical proposition of a positive correlation between risk attitudes and the decision to become self-employed, the effects on survival are not as straightforward. Psychological research posits an inverse U-shaped relationship between risk attitudes and entrepreneurial survival. On the basis ...

Telling the Truth May Not Pay Off: An Empirical Study of Centralized University Admissions in Germany

Matching university places to students is not as clear cut or as straightforward as it ought to be. By investigating the matching algorithm used by the German central clearinghouse for university admissions in medicine and related subjects, we show that a procedure designed to give an advantage to students with excellent school grades actually harms them. The reason is that the three-step process employed ...
