We analyze competition between Internet Service Providers (ISPs) where consumers demand heterogeneous content within two Quality-of-Service (QoS) regimes, Net Neutrality and Paid Prioritization, and show that paid prioritization increases the static efficiency compared to a neutral network. We also consider paid prioritization intermediated by Content Delivery Networks (CDNs). While the use of CDNs ...

Competence in financial decision making is becoming increasingly important. However, most individuals make suboptimal financial decisions. Project A03 examines the hypothesis that these poor decisions may be (partially) caused by behavioral distortions and we explore how these interact with a person’s level of financial literacy. In particular, the project will test the impact of (i) biased...

In this paper, we show that, in terms of real disposable income, changes in housing expenditures dramatically exacerbate the trend of income inequality that has risen sharply in Germany since the mid-1990s. More specifically, whereas the 50/10 ratio of net household income increasesby 22 percentage points (pp) between 1993 and 2013, it increases by 62 pp for income net of housing expenditures.

Does a high regional concentration of immigrants of the same ethnicity affect immigrant children’s acquisition of host-country language skills and educational attainment? We exploit the exogenous placement of guest workers from five ethnicities across German regions during the 1960s and 1970s in a model with region and ethnicity fixed effects. Our results indicate that exposure to a higher own-ethnic ...

We present empirical evidence on the heterogeneity in monetary policy transmission across countries with different home ownership rates. We use household-level data together with shocks to the policy rate identified from high-frequency data. We find that housing tenure reacts more strongly to unexpected changes in the policy rate in Germany and Switzerland –the OECD countries with the lowest home ownership ...

We analyze the introduction and subsequent elimination of university tuition fees in Germany across states and over time in a difference-in-differences setting. Using data ...

Bringing together retail, wholesale, and stock market data, this study estimates how much more consumers are paying for Fairtrade-certified coffee in US supermarkets and finds estimates around $1 per lb. I then assess how this price premium ...
