Three Essays on the Economics of Online Platforms

Die digitale Ökonomie hat unzählige Märkte nachhaltig verändert. Insbesondere Online Plattformen bieten eine noch nie dagewesene Auswahl an Produkten, gekoppelt mit innovativer Technologie, die das Zusammenfinden von Angebot und Nachfrage vereinfacht, Vertrauen aufbaut und Suchkosten reduziert. Gleichzeitig hat die neuartige Natur dieser Plattformen dazu geführt, dass sie teilweise mit den etablierten ...

Learning from Data and Network Effects: The Example of Internet Search

The rise of dominant firms in data driven industries is often credited to their alleged data advantage. Empirical evidence lending support to this conjecture is surprisingly scarce. In this paper we document that data as an input into machine learning tasks display features that support the claim of data being a source of market power. We study how data on keywords improve the search result quality ...

The Effectiveness of FX Interventions: A Meta-Analysis

There is ample empirical literature centering on the effectiveness of foreign exchange intervention (FXI). Given the mix of objectives and country-heterogeneity, the general lack of consensus thus far is no surprise. We shed light on this debate by conducting the first comprehensive meta-analysis in the FXI literature, with 279 reported effects that stem from 74 distinct empirical studies. We cover ...

Repayment under Flexible Loan Contracts: Evidence from Tanzania

We study repayment and delinquency in an innovative loan contract that offers borrowers a wide range of flexibility. Using a large administrative dataset, we perform unsupervised pattern analysis to study how borrowers repay within the framework of this loan. We identify eight clusters that can be grouped into three distinct repayment types. We show that borrowers with fluctuating incomes and limited ...

Airbnb and Rents: Evidence from Berlin

Cities worldwide have regulated peer-to-peer short-term rental platforms claiming that those platforms remove apartments from the long-term housing market, causing an in- crease in rents. Establishing and quantifying such a causal link is, however, challenging. We investigate two policy changes in Berlin to first assess how effective they were in regulating Airbnb, the largest online peer-to-peer short-term ...

Partitioned Pricing and Consumer Welfare

In online commerce, obfuscation strategies by sellers are hypothesized to mislead consumers to their detriment and to the profit of sellers. One such obfuscation strategy is partitioned pricing in which the price is split into a base price and add-on fees. While empirical evidence suggests that partitioned pricing affects consumer decisions through salience effects, its consumer welfare consequences ...

Waiting for My Sentence: Air Pollution and the Productivity of Court Rulings

I assert that air pollution from nitrogen oxides affects the productivity of employees in Mexican court hearings. This is the first article analyzing this connection and the first to disentangle work-breaks from the productivity of white-collar workers. I merge hourly pollution with granular hearing data under the assumption that the length of the hearing approximates productivity and identify causality ...

I Am Innocent: Hourly Variations in Air Pollution and Crime Behavior

I posit that hourly changes in air pollution affect criminality through two distinct pathways, via physiological effects on the criminal and by changes in the tightness of the market for criminal activities. To disentangle individual from market effects, I develop a behavioral model of the individual decision to transgress and a model of search-and-matching frictions between criminals and crime opportunities. ...

Social Inequality in the Digital Transformation: Risks and Potentials of Mobile Health Technologies for Social Inequalities in Health

The paper addresses the impact of digital health technologies on social inequalities in health. We set focus on mobile health technologies (mHealth) and analyse whether (a) usage of such technologies differs by educational level and (b) whether their usage moderate social inequalities in health satisfaction. We first develop a theoretical model in order to establish potential associations between social ...
