The paper provides a new measure of the ethnic identity of immigrants and explores its evolution in the host country. The ethnosizer, a measure of the intensity of a person's ethnic identity, is constructed from information on the following elements: language, culture, societal interaction, history of migration, and ethnic self-identification. A two-dimensional concept of the ethnosizer classifies ...

This paper questions the perceived wisdom that migrants are more risk-loving than the native population. We employ a new large German survey of direct individual risk measures to find that first-generation migrants have lower risk attitudes than natives, which only equalize in the second generation.

This paper analyzes a modified yardstick competition mechanism (MYC), where the yardstick employed consists of a tariff basket and total costs. This mechanism has a significant information advantage: the regulator "only" needs to observe total costs and output of all firms. The modified yardstick competition mechanism can ensure a socially optimal outcome when allowing for spatial and second degree ...

This paper uses a bi-national survey on immigrant performance to investigate the sorting of individuals into full-time paid-employment and entrepreneurship and their economic success. Particular attention is paid to the role of legal status at entry in the host country (worker, refugee, and ...

This papers studies the effects on service quality and consumer surplus of a minimum price which is fixed by a bureaucratic non-monopolistic professional association.

If consumers demand services of lesser quality, the association's ...

European Union economies are pressed by (i) a demographic change that induces population ageing and a decline of the workforce, and (ii) a split labour market that is characterized by high levels of unemployment for low -skilled people and a simultaneous shortage of skilled workers. This lack of flexible high-skilled workers and the aging process has created the image of an immobile labour force and ...

Economically active people are either in gainful employment, are unemployed or self-employed. We are interested in the dynamics of the transitions between these states across the business cycle. It is generally perceived that employment or self-employment are absorbing states. However, innovations, structural changes and business cycles generate strong adjustment processes that lead to fluctuations ...

This paper compares the outcomes of corporate self-regulation and traditional ex-ante regulation of network access to monopolistic bottlenecks. In the model of self-regulation, the domestic gas supplier and network owner and the monopsonistic gas customer fix quantities and the network access price, whereas the competitive fringe of foreign gas producers (third party) and the household customers are ...

There are few studies on occupational choices in Germany, and the second generation occupational choice and mobility is even less investigated. Such research is important because occupations determine success in the labor market. In a country like Germany occupations also reflect a general socio-economic standing. This paper looks at the patterns of employment in Germany, analyzes how individual men ...

The economic literature has largely overlooked the importance of repeat migration. This paper studies repeat or circular migration as it is manifested by the frequency of exits of migrants living in Germany, and by the number of years being away from the host country using count data models. More than 60% of the guestworker generation currently living in Germany, the largest European immigration country, ...
