Digital platforms, empowered by artificial intelligence algorithms, facilitate efficient interactions between consumers and merchants that allow the collection of profiling information which drives innovation and welfare. Private incentives, however, lead to information asymmetries resulting in...

In this paper we investigate the relationship between news sources and media firms. Although empirically important, this channel for supply-driven media bias has not previously been analyzed in economics literature.

These indices capture the predicted error rate in identifying the lottery with the highest expected value, where the predictions are...

While the significance of narrative thinking has been increasingly recognized by social scientists, very little empirical research has documented its consequences for economically significant outcomes. The current paper addresses this gap in one important domain: valuations. In three...
