We consider platform competition when platforms can either 1) commercialize users’ data and in return offer their services for free (data-based business model); 2) protect users’ data and charge users for participation (subscription-based model); or 3) offer both options (the hybrid model).

Despite their recognized importance, the inherent opacity of intra-party institutions limits scholarly understanding of how parties share power internally. We advance knowledge in this area by studying how parties allocate list positions to different factions. We develop a theory of intra-party...

: Since Diamond and Dybvig (1983), banks have been viewed as inherently fragile. We challenge this view in a general mechanism design framework.

Whether it is about choosing a party to vote for, deciding whether to adopt an innovation, selecting music to listen to, or which social media application to use, people tend to select options that many other people have selected before them. This creates a feedback loop in which popular options...

I propose an algorithm that partitions the series of a large vector autoregression (VAR) into groups based on the spillover structure. The novelty of the procedure is that it is capable of simultaneously detecting both the giver and receiver group structures. I study the properties of the algorithm...
