The Role of Paternal Risk Attitudes in Long-Run Education Outcomes and Intergenerational Mobility

This paper studies the role of paternal risk attitudes in sons’ long-run education outcomes and in the intergenerational transmission of incomes and education. Based on 1984–2012 German Socio-Economic Panel Study data of sons and fathers, I show that fathers’ risk aversion is inversely related to sons’ long-run levels of education. A quasi-experimental setting provides no evidence for reverse causality. ...

Veränderungen in der gruppenspezifischen Nutzung von ganztägigen Schulangeboten: Längsschnittanalysen für den Primarbereich

Seit Beginn des Bundes-Investitionsprogramms „Zukunft Bildung und Betreuung“ (IZBB) im Jahr 2003 hat sich der Anteil der Grundschulkinder, die ganztägig eine Schule besuchen, mehr als vervierfacht. Vor diesem Hintergrund untersucht der vorliegende Beitrag zum einen, welche demografischen und sozioökonomischen Merkmale Kinder aufweisen, die ganztägige Schulangebote nutzen. Zum anderen wird der Frage ...

Qualifikationsspezifische Übergänge aus befristeter Beschäftigung am Erwerbsanfang - zwischen Screening und Flexibilisierung

In der vorliegenden Studie werden die Folgen befristeter Beschäftigung am Anfang der Erwerbskarriere für unterschiedliche Qualifikationsgruppen in Deutschland zwischen 1984 und 2010 untersucht. Dazu werden auf Basis der 8. Etappe des Nationalen Bildungspanels (NEPS-E8) Übergänge aus befristeten Erstbeschäftigungen mittels ereignisdatenanalytischer Methoden untersucht. Wie sich zeigt, hängen die Chancen ...

Capital-Flow Management Measures: What Are They Good for?

Are capital controls and macroprudential measures related to international exposures successful in achieving their objectives? Assessing their effectiveness is complicated by selection bias; countries which change their capital-flow management measures (CFMs) often share specific characteristics and are responding to changes in variables that the CFMs are intended to influence. This paper addresses ...

Outside Earnings, Absence, and Activity: Evidence from German Parliamentarians

We examine moonlighting by politicians in Germany. In July 2007, the German Supreme Court adjudicated that members of parliament (MPs) have to publish details of their outside earnings. Using panel data models, we investigate how outside earnings are correlated with absence and parliamentary activity. The results do not indicate that outside earnings are correlated with absence rates and speeches; ...

Power System Impacts of Electric Vehicles in Germany: Charging with Coal or Renewables

We analyze the impacts of future scenarios of electric vehicles (EVs) on the German power system, drawing on different assumptions on the charging mode. We find that the impact on the load duration curve strongly differs between charging modes. In a fully user-driven mode, charging largely occurs during daytime and in the evening, when power demand is already high. User-driven charging may thus have ...

Why Is TFP Growth Sectorally Concentrated?

Research shows that total factor productivity (TFP) growth is weak in European countries. This is inter alia attributed to the fact that substantial TFP growth is limited to a few industries. Because TFP growth is typically understood as technological progress, it is concluded that technology diffusion between sectors in Europe is hampered. We use EU KLEMS data sets to decompose sectoral TFP for nine ...

Personality-Situation Transactions from Adolescence to Old Age

People presumably choose and create their daily environments according to their personality. Prior research shows that, for example, more extraverted people engage more often in social situations, and more conscientious people engage more often in work-related activities compared with less extraverted or less conscientious people, respectively. The current study examined such personality-situation ...

National-Strategic Investment in European Power Transmission Capacity

The transformation of the European electricity system requires substantial investment in transmission capacity to facilitate cross-border trade and to efficiently integrate renewable energy sources. However, network planning in the EU is still mainly a national prerogative. In contrast to other studies aiming to identify the pan-European (continental) welfare-optimal transmission expansion, we investigate ...

Parental Leave Benefits and Breastfeeding in Germany: Effects of the 2007 Reform

While breastfeeding is associated with health benefits for both mothers and children, it may also make it difficult for mothers to return to the labor market early. Maternity and parental leave regulations have been developed to mitigate this conflict. In 2007, Germany passed a reform introducing a new parental leave benefit (Elterngeld). In this paper, we address the question of whether the new parental ...

Race to the Debt Trap? Spatial Econometric Evidence on Debt in German Municipalities

Through an intertemporal budget constraint, jurisdictions may gain advantages in tax and spending competition by ‘competing’ on debt. While the existing spatial econometric literature focuses on tax and spending competition, very little is known about spatial interaction via public debt. If jurisdictions compete for mobile capital to finance public spending, they may compete in debt levels as well ...

The Earnings Return to Graduating with Honors: Evidence from Law Graduates

This paper aims at studying the causal effects of graduating from a university with an honors degree on subsequent earnings. While a rich body of literature has focused on estimating returns to human capital, few studies have analyzed returns at the very top of the education distribution. We highlight the importance of honors degrees for future labor market success in the context of German law graduates. ...

Flight to Liquidity and the Great Recession

This paper argues that counter-cyclical liquidity hoarding by financial intermediaries may strongly amplify business cycles. It develops a dynamic stochastic general equilibrium model in which banks operate subject to agency problems and funding liquidity risk in their intermediation activity. Importantly, the amount of liquidity reserves held in the financial sector is determined endogenously: Balance ...

Drivers of Structural Change in Cross-Border Banking since the Global Financial Crisis

The paper analyzes the effects of changes to regulatory policy and to monetary policy on cross-border bank lending since the global financial crisis. Cross-border bank lending has decreased, and the home bias in the credit portfolio of banks has risen sharply, especially among banks in the euro area. Our results suggest that expansionary monetary policy in the source countries – as measured by the ...

Integrating Intermittent Renewable Wind Generation: A Stochastic Multi-Market Electricity Model for the European Electricity Market

In northern Europe, wind energy has become a dominate renewable energy source, due to natural conditions and national support schemes. However, the uncertainty about wind generation affects existing network infrastructure and power production planning of generators, which cannot be fully diminished by wind forecasts. In this paper we develop a stochastic electricity market model to analyze the impact ...

Why Did Self-Employment Increase so Strongly in Germany?

Effort and Performance: What Distinguishes Interacting and Noninteracting Groups from Individuals?

We study how group membership affects behavior both when group members can and cannot interact with each other. Our goal is to isolate the contrasting forces that spring from group membership: a free-riding incentive leading to reduced effort and a sense of social responsibility that increases effort. In an environment with varying task difficulty and individual decision making as the benchmark, we ...

A Note on Networks of Collaboration in Multi-market Oligopolies

In this note, we extend the Goyal and Joshi’s model of collaboration networks in oligopoly to multi-market situations. We examine the incentive of firms to form links and the architectures of the resulting equilibrium networks in this setting. We then present some results on efficient networks.

Signature Requirements and Citizen Initiatives: Quasi-experimental Evidence from Germany

Signature requirements are often used as hurdles to prevent overuse of direct democratic instruments such as citizen initiatives. We evaluate the causal effect of lowering signature requirements on the number of observed citizen initiative petitions. Based on municipal-level data for Germany, we make use of changes in signature requirements that occur at specific population thresholds to build an identification ...

Can't Get It out of My Head: Age Differences in Affective Responsiveness Vary with Preoccupation and Elapsed Time after Daily Hassles

To better understand age differences in negative affective responses to daily hassles, the current study investigated how responses may depend on how much time has elapsed after the hassle and how much one still thinks about the hassle. In an experience-sampling approach with mobile phones, 397 participants aged 12 to 88 years reported their momentary activating (e.g., angry) and deactivating (e.g., ...
