This paper provides first empirical insights on the relationship between green public procurement (GPP) and firms' innovation activities. Considering that the public sector is a large buyer in the economy, public procurement is able to work as demand-pull factor for new products and thus innovations - given that the procurement is aimed at such objectives. GPP is specifically implemented to contribute ...

CO2-Abgaben bergen die Gefahr, einkommensschwächere Haushalte überdurchschnittlich zu belasten. Zur Abwehr solcher regressiven Verteilungswirkungen wird erwogen, einen Teil der Einnahmen durch einen Pro-Kopf-Bonus an die Bürger*innen zurückzugeben. Der vorliegende Beitrag entwickelt einen Vorschlag für einen in das deutsche Krankenversicherungssystem integrierten Bonus. Dazu werden zunächst die Ziele ...

Gegenwärtig sind die verschiedenen Energieträger in Deutschland unterschiedlich stark mit Abgaben und Umlagen belastet. Um die energie- und klimapolitischen Ziele der Bundesregierung zu erreichen, müssen fossile Heiz- und Kraftstoffe stärker bepreist werden (Kemfert et al. 2019; Dertinger und Schill 2019, SRU 2019). Zugleich herrscht in der energiepolitischen Debatte Uneinigkeit über die die Ausgestaltung ...

We present evidence that the practice of holding back poorly performing students affects estimates of the impact of class size on student outcomes based on within-school variation of cohort size over time. This type of variation is commonly used to identify class size effects. We build a theoretical model in which cohort size is subject to random shocks and students whose performance falls below a ...

In this study, we set up a DSGE model with upward looking consumption comparison and show that consumption externalities are an important driver of consumer credit dynamics. Our model economy is populated by two different household types. Investors, who hold the economy’s capital stock, own the firms and supply credit, and workers, who supply labor and demand credit to finance consumption. Furthermore, ...

Although universal childcare has become an essential tool to support child development, few economic studies analyze its effects on non-cognitive skills and little is known about causal effects on these skills in the long run. In this paper we go beyond short run analyses and examine the long run effects of one additional year of universal childcare on students’ personality traits in adolescence. We ...

Macroprudential policies for financial institutions have received increasing prominence since the global financial crisis. These policies are often aimed at the commercial banking sector, while a host of other non-bank financial institutions, or shadow banks, may not fall under their jurisdiction. We study the effects of tightening commercial bank regulation on the shadow banking sector. For this purpose, ...

In energy efficiency networks, groups of firms exchange experiences on energy conservation in regular meetings over several years. The companies implement energy efficiency measures in order to reach commonly agreed energy savings and CO2 reduction goals. Existing evaluations of such voluntary regional networks claim that participants improved energy efficiency at twice the speed of the industry average. ...

This paper analyzes the impact of urbanization on CO2 emissions within the STIRPAT framework over the period 1971 to 2014 for a panel of 76 countries clustered into income groups. Using dynamic panel estimations techniques, the empirical results robustly show an inverted N-shaped relationship between urbanization and CO2 emissions in the long-term associated with the ecological modernization theory ...

This paper analyzes the nature of democratic development in a nation on the process of introducing nuclear power over the period 1960 - 2017 for an unbalanced panel of 171 countries. Given the involved political process of introducing nuclear power and its political importance, as well as the current tendency of about 30 countries to “go nuclear”, this question is both of historic and current interest. ...

We examine the introduction of a gender quota law in Germany, mandating a minimum 30% of the underrepresented gender on the supervisory boards of a particular type of firms. We exploit the fact that Germany has a two-tier corporate system consisting of the affected supervisory boards and unaffected management boards within the same firm. We find a positive effect on the female share on supervisory ...

This paper analyzes the impact of a reduction in women's labor supply through retirement on their informal care provision. Using SOEP data from the years 2001- 2016 the analysis addresses fundamental endogeneity problems by applying a fuzzy regression discontinuity design. We exploit early retirement thresholds for women in the German pension system as instruments for their retirement decision. We ...

We document day care enrolment gaps by family background for children under 3 in Germany. Research demonstrates that children of less-educated or foreign-born parents benefit most from day care, making it important to understand the causes of such enrolment gaps. Using a unique data set that records both actual and preferred day care usage, we demonstrate that differences in demand cannot fully explain ...

In this paper, we analyse the effects of a unilateral change in an emissions tax in a model of international trade with heterogeneous firms. We find a positive effect of tighter environmental policy on average productivity in the reforming country through reallocation of labour towards exporting firms. Domestic aggregate emissions fall, due to both a scale and a technique effect, but we show that the ...

This study investigates the interrelation between the household leverage cycle, collateral constraints, and monetary policy. Using data on the U.S. economy, we find that a contractionary monetary policy shock leads to a large and significant fall in economic activity during periods of household deleveraging. In contrast, monetary policy shocks only have insignificant effects during a household leveraging ...

Does the federal minimum wage in Germany introduced in 2015 improve the income situation of low income households and reduce in-work poverty? Previous literature on its distributional impact was either focused on earnings and hourly wages (e.g. Caliendo et al., 2017), or is based on ex-ante simulations (e.g. Müller and Steiner, 2013). This paper provides systematic descriptive ex-post evidence on the ...

With more than ten thousand casualties, the 2014 Ukrainian war between pro-Russian separatists and the government in the Donbass region, Ukraine's productive core, has taken a severe toll on the country. Using cross-country panel data over the period 1995-2017, this paper quantifies the short-term causal effects of the Donbass war on Ukraine's GDP. Results from the counterfactual estimation by the ...

Antibiotic resistance constitutes a major health threat. Predicting bacterial causes of infections is key to reducing antibiotic misuse, a leading cause of antibiotic resistance. We combine administrative and microbiological laboratory data from Denmark to train a machine learning algorithm predicting bacterial causes of urinary tract infections. Based on predictions, we develop policies to improve ...

While several studies suggest that stress-related mental health problems among school children are related to specific elements of schooling, empirical evidence on this causal relationship is scarce. We examine a German schooling reform that increased weekly instruction time and study its effects on stress-related outpatient diagnoses from the universe of health claims data of the German Social Health ...

The loss of international competitiveness of domestic industries remains a key obstacle to the implementation of effective carbon prices in a world without harmonized climate policies. We analyze countries' non-cooperative choices of emissions taxes under imperfect competition and mobile polluting firms. In our general equilibrium setup with trade, wage effects prevent all firms from locating in the ...
