The ethnosizer, a new measure of the intensity of a person's ethnic identity, is proposed using information on language, culture, societal interaction, history of migration, and ethnic self-identification. A two-dimensional version classifies immigrants into four states: integration, assimilation, separation and marginalization. Results based on the German Socio-economic Panel for 2001 are as follows. ...

The positive association between moderate alcohol consumption and wages is well documented in the economic literature. Positive health effects as well as networking mechanisms serve as explanations for the "alcohol-income puzzle". Using individual-based microdata from the SOEP for 2006, we confirm that this relationship exists for Germany as well. More importantly, we shed light on the alcohol-income ...

Most models that are used to analyze support policies for renewable electricity neglect important market features like oligopolistic behavior, emission trading, and restricted cross-border transmission capacities. We use a quantitative electricity market model that accounts for these aspects and decompose the impact of the German Feed-in tariff (FIT) into two frequently counteracting effects: a substitution ...

This article introduces a special issue on the micro-level dynamics of mass violent conflict. While most analyses of conflict typically adopt a regional, national or global perspective, often using country-level data, this special issue takes an explicit micro-level approach, focusing on the behaviour and welfare of individuals, households and groups or communities. At a fundamental level, conflict ...

This article analyzes the effects of household-level activity choices on farm household welfare in a developing country affected by mass violent armed conflict. The study uses household survey data from postwar Nampula and Cabo Delgado provinces in Northern Mozambique capturing many activity choices, including market participation, risk and activity diversification, cotton adoption, and social exchange, ...

When potential income tax reforms are debated, the suspected impact on entrepreneurship is often used as an argument in favour of or against a certain policy. Quantitative ex-ante evaluations of the effect of certain tax reform options on entrepreneurship are very rare, however. This paper estimates the ex-ante effects of the German tax reform 2000 and of two hypothetical flat-rate tax scenarios on ...

This paper investigates the link between the optimal level of nonfinancial firms' short-term leverage and macroeconomic and idiosyncratic sources of uncertainty. We develop a structural model of a firm's value maximization problem that predicts a negative relationship between uncertainty and optimal levels of borrowing. This proposition is tested using a panel of nonfinancial U.S. firms drawn from ...

The influence of risk aversion on the decision to become self-employed is a much discussed topic in the entrepreneurial literature. Conventional wisdom asserts that being an entrepreneur means making risky decisions; hence more risk-averse individuals are less likely to become entrepreneurs. In contrast to previous research, we are able to examine empirically whether the decision of starting a business ...

Die Greifkraftmessung stellt nicht nur eine sinnvolle Ergänzung zu selbst berichteten Indikatoren des Gesundheitszustandes dar, sondern besitzt darüber hinaus hinsichtlich einer Vielzahl insbesondere ...

In Europe, two market designs are discussed for electricity trade and transmission. We argue that their performance in the presence of market power can be represented by two models from the literature. In contrast to examples for simple two-node networks, we show that in more complex networks a general ranking of both designs is not possible. Hence, computational models are required to evaluate the ...
