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.

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 ...

Emergency Aid for Self-Employed in the COVID-19 Pandemic: A Flash in the Pan?

The self-employed are among those facing the highest probability of strong income losses during the COVID-19 pandemic.

We investigate patterns in common ownership networks between firms that are active in the US pharmaceutical industry for the period 2004-2014. Our main findings are that “brand firms” — i.e. firms that have R&D capabilities and launch new drugs — exhibit relatively dense common ownership networks with each other that further increase significantly in density over time, whereas the network of “generic ...
