Nonparametric Regression with Selectively Missing Covariates

We consider the problem of regression with selectively observed covariates in a nonparametric framework. Our approach relies on instrumental variables that explain variation in the latent covariates but have no direct effect on selection. The regression function of interest is shown to be a weighted version of observed conditional expectation where the weighting function is a fraction of selection ...

Merger Policy in Digital Markets: An Ex-Post Assessment

This paper presents a broad retrospective evaluation of mergers and merger decisions in markets dominated by multisided digital platforms. First, we document almost 300 acquisitions carried out by three major tech companies—Amazon, Facebook, and Google—between 2008 and 2018. We cluster target companies on their area of economic activity providing suggestive evidence on the strategies behind these mergers. ...

The Appropriateness of the Macroeconomic Imbalance Procedure for Central and Eastern European Countries

The European Commission’s Scoreboard of Macroeconomic Imbalances is a rare case of a publicly released early warning system. It was published first time in 2012 by the European Commission as a reaction to public debt crises in Europe. So far, the Macroeconomic Imbalance Procedure takes a one-size-fits-all approach with regard to the identification of thresholds. The experience of Central and Eastern ...

Prejudice in Disguise: Which Features Determine the Subtlety of Ethnically Prejudicial Statements?

In current immigration debates ethnic prejudice is often expressed in a subtle manner, which conceals its xenophobic content. However, previous research has only insufficiently examined the specific features that make certain ethnically prejudicial statements subtler, i.e., less readily identifiable as xenophobic, than others. The current study employs an experimental factorial survey design and assesses ...

Closing Routes to Retirement for Women: How Do They Respond?

We study the employment effects of a large increase in the early retirement age (ERA) of women. Raising the ERA has the potential to extend contribution periods and to reduce the number of pensioners at the same time. However, workers may not be able to work longer or may choose other social support programs as exit routes from employment. Results suggest that the reform increases employment, unemployment ...

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

Distributional Impacts of Carbon Pricing: A Meta-Analysis

Understanding the distributional impacts of market-based climate policies is crucial to design economically efficient climate change mitigation policies that are socially acceptable and avoid adverse impacts on the poor. Empirical studies that examine the distributional impacts of carbon pricing and fossil fuel subsidy reforms in different countries arrive at ambiguous results. To systematically determine ...

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 ...

Comparing Regulatory Designs for the Transmission of Offshore Wind Energy

Offshore wind plays an ever-increasing role for the global transition to renewable energy. For offshore wind energy to be successful, cost-effective transport of the produced electricity to shore is necessary. The development and operation of the offshore transmission asset is costly and regulated differently across the globe. In most countries, the TSO is responsible for the transmission and develops ...
