The empirical relationship between income and longevity has been addressed by a large number of studies, but most were confined to men. In particular, administrative data from public pension systems are less reliable for women because of the loose relationship between own earnings and household income. Following the procedure first used by Hupfeld (2010), we analyze a large data set from the German ...

Boone (2008a) proposes a new competition measure based on Relative Profit Differences (RPD) with superior theoretical properties. However, the empirical applicability and robust-ness of the Boone-Indicator is still unknown. This paper aims to address that question. Using a rich, newly built, data set for German manufacturing enterprises, we test the empirical valid-ity of the Boone-Indicator using ...

This paper investigates the effect of ethnicity on time spent on overlapped household production, work and leisure activities employing the 2000-2001 UK Time Use Survey. We find that, unconditionally, white females manage to "stretch" their time the most by an additional 233 minutes per day and non-white men "stretch" their time the least. The three secondary activities that are most often combined ...

Standard job search theory assumes that unemployed individuals have perfect information about the effect of their search effort on the job offer arrival rate. In this paper, we present an alternative model which assumes instead that each individual has a subjective belief about the impact of his or her search effort on the rate at which job offers arrive. These beliefs depend in part on an individual's ...

In many economic contexts, an elusive variable of interest is the agent's expectation about relevant events, e.g. about other agents' behavior. Recent experimental studies as well as surveys have asked participants to state their beliefs explicitly, but little is known about the causal relation between beliefs and other behavioral variables. This paper discusses the possibility of creating exogenous ...

This chapter investigates the integration processes of immigrants in Germany by comparing certain immigrant groups to natives differentiating by gender and immigrant generation. Indicators which are supposed to capture cultural integration of immigrants are differences in marital behavior as well as language abilities, ethnic identification and religious distribution. A special feature of the available ...

This paper is based on recently collected and rich survey data of a representative sample of entrants into unemployment in Germany. Our data include a large number of migration variables, allowing us to adapt a recently developed concept of ethnic identity: the ethnosizer. To shed further light on the native-migrant differences in economic outcomes, we investigate the labor market reintegration, patterns ...

Der vorliegende Beitrag ist eine Metaanalyse von 99 deutschen Bevölkerungssurveys aus dem GESIS-Datenarchiv, in denen die postmaterialistische Einstellung der Befragten ermittelt wird. Es wird anhand von Mehrebenenmodellen gezeigt, dass sich der Anteil der Postmaterialisten unter Kontrolle von Geburtsjahr der Befragten und Erhebungsjahr des Surveys überzufällig zwischen den Surveys unterscheidet. Diese ...

This chapter deals with the economic and ethnic diversity caused by international labor migration, and their economic integration possibilities. It brings together three strands of literature dealing with the neoclassical economic assimilation, ethnic identities and attitudes towards immigrants and the natives, and provides an analysis in understanding their interactions. The issue of how immigrants ...

The Arrow index of a fuzzy choice function C is a measure of the degree to which C satisfies the Fuzzy Arrow Axiom, a fuzzy version of the classical Arrow Axiom. The main result of this paper shows that A(C) characterizes the degree to which C is full rational. We also obtain a method for computing A(C). The Arrow index allows to rank the fuzzy choice functions with respect to their rationality. Thus, ...
