Antibiotics have contributed to a tremendous increase in human well-being, saving many millions of lives. However, antibiotics become obsolete the more they are used as selection pressure promotes the development of resistant bacteria. The World Health Organization has proclaimed antibiotic resistance as a major global threat to public health. Today, 700,000 deaths per year are due to...

Cartels can severely harm social welfare. Competition authorities introduced leniency rules to destabilize existing cartels and hinder the formation of new ones. Empirically, it is difficult to judge the success of these measures because functioning cartels are unobservable. Existing experimental studies confirm that a leniency rule indeed reduces cartelization. We extend these studies by having a ...

Based on a dynamic life cycle model, this study analyzes health-related risks of consumption and old-age poverty. The model allows for health effects on employment risks, on productivity, on longevity, the correlation between health risks, productivity and preferences, and the financial incentives of the German public insurance schemes. The estimation uses data on male employees and an extended expectation-maximization ...

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 ...

Most simulated micro-founded macro models use solely consumer-demand aggregates in order to estimate preference parameters of a representative consumer, for use in policy evaluation. Focusing on dynamic models with time-separable preferences, we show that aggregation holds if, and only if, momentary utility functions fall in the Identical-Shape Harmonic Absolute-Risk Aversion (ISHARA) utility class, ...

This RCT examines the effect of a new style finance training during which participants are given personalized feedback on their financial business outcomes in addition to a “rules-of-thumb” training approach. We compare this to the effects of a “rules-of-thumb” training by itself and to a control group. Targeting about 500 small and micro entrepreneurs in Kampala, Uganda, we find that the personalized ...

Although households in developing and emerging countries are relatively poor, there is potential to save. For example, one study estimates that up to 8.1% of a poor household’s budget in such countries is spent on so-called temptation goods, like alcohol, tobacco, and festivals (Banerjee and Duflo, 2007). At the same time, many households are aware of the fact that they do not save enough. They name ...

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, ...

The expansion of renewable energies requires infrastructure investments to at least maintain the stability of electricity grids. Using survey data from residential consumers in Germany and Great Britain, we infer in pecuniary terms the extent to which people are prepared to reward the presence of renewable resources in electricity production and how they trade off this change in the fuel mix against ...

We study a game in which two firms compete in quality to serve a market consisting of consumers with different initial consideration sets. If both firms invest below a certain quality threshold, they only compete for those consumers already aware of their existence. Above this threshold, a firm is visible to all and the highest quality attracts all consumers. In equilibrium, firms do not choose their ...
