We analyze mergers between strategic data intermediaries collecting consumer information that they sell to firms competing in a product market. We show that a merger: (a) reduces the intensity of competition in the product market through a change in the selling strategies of merging intermediaries; (b) increases data collection, reducing consumer surplus through a better rent extraction. We argue...

Since decades, only one fourth of German households invest in shares. One exception was during the three IPOs from 1996 to 2000 of the Deutsche Telekom, which gave Germans a taste to enter the stock market. However, the fall in the share price shortly after the second IPO, followed by corruption scandals of the company, put an end to their enthusiasm. The present study based on SOEP data shows that ...

We conduct a randomized field experiment to study the effects of two financial education interventions offered to small-scale retailers in rural western Uganda. The treatments contrast “active learning” with traditional “lecturing” within standardized lesson-plans.

When examining data from 76 financial education randomized experiments across 33 countries covering over 160,000 individuals, we find that financial education improves both ...

Mobile money is an important instrument to improve the degree of financial inclusion, especially in developing countries. However, having a mobile money account does not imply that this account is actually used. In our sample, 86% of microentrepreneurs own a mobile money account, but only 49% actively use it – the resulting gap indicates unmet opportunities. We estimate that mobile money reaches up ...

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 threshold, they only compete for those consumers already aware of their existence. Above this threshold, a firm is visible to all and the highest investment attracts all consumers. On the one hand, the existence of initially ...
