Typically, when two people decide to become parents, they procreate by copulation and produce a child. What do people do if, for some reason, they can?t produce their own children but want to be parents? Today, a prospective parent can go to the web, drop a vial of sperm from a donor with...

This paper studies how an institution such as markets affects the evolution of mankind. My key point is that the forces of natural selection are made weaker because trade allows people to specialize in those activities where they are strong, and to offset their weaknesses by purchasing adequate...

The increasing use of demand-side management as a tool to reliably meet electricity demand at peak time has stimulated interest among researchers, consumers and producer organizations, managers, regulators and policymakers, This research reviews the growing literature on models used to study...

We quantify the value of changes in life circumstances in Germany following reunification. To this end, we develop and implement a fixed-effect estimator for ordinal life satisfaction in the German Socio-Economic Panel. We find strong negative effects on life satisfaction from being recently...

This paper presents a methodology to identify net demand shocks as well as wage rigidities in heterogeneous labor markets on the basis of nonparametric regression. We show how this approach can be used to make suggestions for immigration policy in economies with labor market rigidities. In an...

Folklore has it that the comparatively low proportion of self-employed in Germany is in part due to a habit that might be termed 'stigmatisation of failure': taking a second chance to build one's own firm after failing as a self-employed is said to be much more difficult here than in other...

Based on data from the BHPS and the GSOEP, we analyse the economic performance of various ethnic groups in the UK and West Germany, as well as the effects of income redistribution on these populations. Taking the indigenous population of each country as the reference category, we find that, as a...

In a sharp break with past German research, some recent estimates have suggested that plants with work councils have 25 to 30 per cent higher productivity than their works-councilfree counterparts. Such findings can only serve to buttress the strong theoretical and policy interest in the German...

In this paper we define and estimate measures of labor market frictions using data on job durations. We compare different estimation methods and different types of data. We propose and apply an unconditional inference method that can be applied to aggregate duration data. It does not require...

Using detailed time use data for Germany a positive correlation is found between the level of schooling education and time investments in informal education. Two hypotheses explain this observation: (1) highly educated people have higher opportunity costs of their leisure time and thus prefer...
