Cost Efficiency and Endogenous Regulatory Choices: Evidence from the Transport Industry in France

We study the impact of different regulatory designs on the cost efficiency of operators providing a public service, exploiting data from the French transport industry. The distinctive feature of the study is that it considers regulatory regimes as endogenously determined choices, explained by economic, political, and institutional variables. Our approach leans on a positive analysis to study the determinants ...

Consequences of Overeducation among Career Starters in Germany: A Trap for the Vocationally Trained as well as for University Graduates?

Research on the consequences of starting in overeducation often focuses on either secondary or tertiary graduates. We focus on both within one country, Germany. While matching and search models imply the improvement of initial overeducation, human capital theory and stigma associated with overeducation predict entrapment. The strongly skill- and occupation-based labour market for the vocationally trained ...

Sovereign Default Risk, Macroeconomic Fluctuations and Monetary–Fiscal Stabilization

This paper examines the role of sovereign default beliefs for macroeconomic fluctuations and stabilization policy in a small open economy where fiscal solvency is a critical problem. We set up and estimate a DSGE model on Turkish data and show that accounting for sovereign risk significantly improves the fit of the model through an endogenous amplification between default beliefs, exchange rate and ...

The Challenged Sense of Belonging Scale (Csbs): A Validation Study in English, Arabic, and Farsi/Dari among Refugees and Asylum Seekers in Germany

This study introduces and investigates the validity of a brief scale measuring a challenged sense of belonging. The sense of belonging as well as challenges to this sense are important, albeit neglected aspects of social integration and of significance to migration and refugee studies as well as to virtually all other social science contexts. Assessing a challenged or eroded sense of belonging provides ...

Using a Mobile App When Surveying Highly Mobile Populations: Panel Attrition, Consent, and Interviewer Effects in a Survey of Refugees

Panel attrition poses major threats to the survey quality of panel studies. Many features have been introduced to keep panel attrition as low as possible. Based on a random sample of refugees, a highly mobile population, we investigate whether using a mobile phone application improves address quality and response behavior. Various features, including geo-tracking, collecting email addresses and adress ...

All-Pay Competition with Captive Consumers

We study a game in which two firms compete in quality to serve a market consisting of consumers with different initial consideration sets. If both firms invest below a certain threshold, they only compete for those consumers already aware of their existence. Above this threshold, a firm is visible to all and the highest investment attracts all consumers. On the one hand, the existence of initially ...

A Tale of Two Countries: The Long Shadow of the Crisis on Income and Wealth in Germany and Italy

The Role of Aggregators in Facilitating Industrial Demand Response: Evidence from Germany

Industrial demand response can play an important part in balancing the intermittent production from a growing share of renewable energies in electricity markets. This paper analyses the role of aggregators – intermediaries between participants and power markets – in facilitating industrial demand response. Based on the results from semi-structured interviews with German demand response aggregators, ...

Economic Competence in Early Secondary School: Evidence from a Large-Scale Assessment in Germany

We employ a psychometrically validated performance test to study economic competence among representative sample of 1,687 early secondary school students in Southwest Germany. The rich dataset allows us to study variation in economic competence across school types and observable student characteristics. Our results show that economic competence is significantly lower among female students, migrants, ...

Parental Separation during Childhood and Adult Children’s Wealth

This study examines the association between parental separations during childhood and economic wealth of adult children. We provide a new test of this relationship and address two unresolved debates in the literature concerning (1) the pathways linking parental separation and adult children’s wealth and (2) the relevance of the timing of exposure. We use data from the Household, Income and Labour Dynamics ...

Assessment of German Public Attitudes toward Health Communications with Varying Degrees of Scientific Uncertainty Regarding COVID-19

This survey study assesses attitudes of the German public regarding COVID-19 health communications with varying degrees of scientific uncertainty.

Gender Identity and Wives’ Labor Market Outcomes in West and East Germany between 1983 and 2016

We exploit the natural experiment of German reunification in 1990 to investigate if the institutional regimes of the formerly socialist (rather gender-equal) East Germany and the capitalist (rather gender-traditional) West Germany resulted in differing gender norms regarding who should be the family breadwinner. We use data for three periods between 1983 and 2016 from the German Socio-Economic Panel. ...

The U.S. Coal Sector between Shale Gas and Renewables: Last Resort Coal Exports?

Coal consumption and production have sharply declined in recent years in the U.S., despite political support. Reasons are mostly unfavorable economic conditions for coal, including competition from natural gas and renewables in the power sector, as well as an aging coal-fired power plant fleet. Nevertheless, coal remains a major energy source in the North American energy markets. Supplementing EMF34 ...

Great Expectations: Reservation Wages and Minimum Wage Reform

This paper is the first causal study using quasi-experimental methods to identify the effect of minimum wages on the reservation wages of non-workers. We exploit variation in regional exposure to the introduction of a high-impact minimum wage in Germany in 2015, combined with survey responses about wage acceptance thresholds of job seekers. Results show a 16% increase in reservation wages among non-employed ...

2D:4D and Self-Employment: A Preregistered Replication Study in a Large General Population Sample

The 2D: 4D digit ratio, the ratio of the length of the second finger to the length of the fourth finger, is often considered a proxy for testosterone exposure in utero. A recent study reported, among other things, an association between the left-hand 2D:4D and self-employment in a sample of 974 adults. In this preregistered study, we replicate the 2D:4D results on a sample of more than 2100 adults ...

Top of the Class: The Importance of Ordinal Rank

This article establishes a new fact about educational production: ordinal academic rank during primary school has lasting impacts on secondary school achievement that are independent of underlying ability. Using data on the universe of English school students, we exploit naturally occurring differences in achievement distributions across primary school classes to estimate the impact of class rank. ...

Cohort Changes in the Level and Dispersion of Gender Ideology after German Reunification: Results from a Natural Experiment

Modernization theorists’ ‘rising tide hypothesis’ predicted the continuous spread of egalitarian gender ideologies across the globe. We revisit this assumption by studying reunified Germany, a country that did not follow a strict modernization pathway. The socialist German Democratic Republic (GDR) actively fostered female employment and systematically promoted egalitarian ideologies before reunification ...

Parental Well-Being in Times of Covid-19 in Germany

We examine the effects of Covid-19 and related restrictions on individuals with dependent children in Germany. We specifically focus on the role of day care center and school closures, which may be regarded as a “disruptive exogenous shock” to family life. We make use of a novel representative survey of parental well-being collected in May and June 2020 in Germany, when schools and day care centers ...

Non-migrants’ and Migrants’ Interethnic Relationships: The Third Party Role of Cohabiting Partners

Considering both non-migrant and migrant couples, this paper studies the effect of cohabiting life partners’ attitudes, resources, and social network compositions on their spouse’s interethnic friendships and acquaintances. Thus, partners are conceptualized as important “third parties” for interethnic relationship formation. Analysing representative German household panel data, I find that partner ...

Gendered Employment Trajectories and Individual Wealth at Older Ages in Eastern and Western Germany

This study examines the association between employment trajectories and retired men’s and women’s individual wealth at older ages in the two distinct welfare state contexts of Eastern and Western Germany. Because of the increasing re-marketization of retirement provisions, wealth is becoming increasingly important for retirees’ economic well-being. Using data from the German Socio-Economic Panel Study ...
