This paper investigates the association between maternal life satisfaction and the developmental functioning of 2-3-year-old children as well as the socio-emotional behavior of 5-6-year-old children. We use data from the German Socio-Economic Panel Study (SOEP), which allows us to control for a rich set of child and parental characteristics and to use the mother's life satisfaction before the birth ...

This paper considers enhancements of a comparatively new method to detect cartels, the System of Cartel Markers (SCM), introduced by Blanckenburg and Geist (Int Adv Econ Res 15(4):421-436, 2009). The aim of SCM is to find illegal collusion on legal markets with observable market data. It uses expected behavior patterns such aslow level of capacity utilization, slackness of price adjustments to exogenous ...

The importance of repeat and circular migration starts receiving rising recognition. The paper studies this behavior by analyzing the number of exits and the total number of years away from the host country using count data models and panel data from the German guestworker experience. Beyond the myth, more than 60% of migrants in the sample from the guestworker countries living in Germany are indeed ...

Research on ethnolinguistic heterogeneity has so far mostly focused on domestic measures, while little attention has been paid to ethnolinguistic relations between nations. In this paper, I propose a way of measuring ethnolinguistic affinity between nations. This index measures the degree of similarity two randomly drawn individuals from two different populations are expected to display. I show that ...

Several German states recently introduced tuition fees for university education. We investigate whether these tuition fees influence the mobility of university applicants. Based on administrative data of applicants for medical schools in Germany, we estimate the effect of tuition fees on the probability of applying for a university in the home state. We find a small but significant reaction: The probability ...

We develop a structural model of female employment and fertility which accounts for intertemporal feedback effects between these two outcomes. To identify the effect of financial incentives on employment and fertility we exploit variation in the tax and transfer system, which differs by employment state and number of children. Specifically, we simulate in detail the effects of the tax and transfer ...

We analyse preferences for public, private or mixed provision of childcare theoretically and empirically. We model childcare as a publicly provided private good. Richer households should prefer private provision to either pure public or mixed provision. If public provision redistributes from rich to poor, the rich should favour mixed over pure public provision, but if public provision redistributes ...

Means-tested student aid might affect enrollment in higher education. To derive the potential influence of student aid, we use a tax-benefit microsimulation model. The effect is a non-linear function of parental income, with variation as a result of bracket creeping and various reforms. Therefore, the effect of student aid on enrollment can be separated from the effects of income and other family characteristics. ...

The authors analyse newly collected time-series data measuring the dimensions of violent political conflict in Egypt. Attention is focused on the interaction between politically motivated attacks by Islamists and the counter-insurgency measures used by the Egyptian government. Both insurgency and counter-insurgency are multidimensional. Insurgencyincludes attacks on tourists, on Egyptian civilians ...

The empirical finding that entrepreneurs invest a large share of their wealth in their own firms, despite comparably low returns and high risk, has become known as the private equity premium puzzle. This paper provides evidence supporting the hypothesis that lower risk-aversion of entrepreneurs, and thus not necessarily credit constraints, may explain this puzzle. The analysis is based on a representative ...

We study the strategic utilization of storage in imperfect electricity markets. We apply a game-theoretic Cournot model to the German power market and analyze different counterfactual and realistic cases of pumped hydro storage. Our main finding is that both storage utilization and storage-related welfare effects depend on storage ownership and the operator's involvement in conventional generation. ...

This paper presents results about the determinants of export behaviour of services firms. Using a unique panel of enterprises for the years 2003 to 2005, the impact of size, productivity, human capital, experience on the national market, etc. on export behaviour are analysed. In addition, the researchers control for unobserved time-invariant characteristics by using a pooled fractional probit estimator. ...

Der Übergang von der Grundschule in die mehrgliedrige Sekundarstufe ist in Deutschland entscheidend für den weiteren Bildungsverlauf, da spätere Wechsel der Schulform zwar möglich sind, aber nur relativ selten stattfinden. In diesem Papier betrachten wir den Einfluss der Akzeptanz der Schullaufbahnempfehlungen am Ende der Grundschulzeit auf den Bildungsverlauf bis zum Alter von 17 Jahren. Die Datengrundlage ...

The paper presents a meta dataset covering 13 experiments on social learning games. It is found that in situations where it is empirically optimal to follow others and contradict one's own information, the players err in the majority of cases, forgoing substantial parts of earnings. The average player contradicts her own signal only if the empirical odds ratio of the own signal being wrong, conditional ...

This paper investigates the impact of governance structure on firm performance (i.e., retail prices) using a database of 765 German water suppliers. Controlling for scale economies as well as technical and structural characteristics, we find that private sector participation is accompanied with higher retail prices. Furthermore, Eastern states on average feature higher prices mirroring significant ...

The real interest parity (RIP) condition combines two cornerstones in international finance, uncovered interest parity (UIP) and ex ante purchasing power parity (PPP). The extent of deviation from RIP is therefore an indicator of the lack of product and financial market integration. This paper investigates whether the nominal exchange rate regime has an impact on RIP. The analysis is based on 15 annual ...

This paper analyses whether aid channelled through non-governmental organisations (NGOs) is less affected by selfish donor motivations and better targeted to needy recipient countries than aid distributed by state agencies. We employ Tobit (and Probit) models and make use of an exceptionally detailed database that allows an assessment of the allocation of Swedish aid channelled through NGOs in comparison ...

In political economics, the impact of institutions on income redistribution is mainly studied by comparing different forms of representative democracy. In this article, we analyze the influence of direct democratic institutions on redistribution first focusing on welfare and nonwelfare spending using yearly panel data for Swiss cantons. Then, we estimate a model, which explains the determinants of ...
