We study the development of apps on competing platforms. We show that competition leads to commissions exceeding those maximizing consumer surplus (and, a fortiori, social welfare) whenever raising one commission reduces rivals' app bases. We relate this nding to economies of scope in app...

An agent learns dynamically about the profitability of a project and decides when to make an irreversible investment. The agent seeks to maximize his reputation for learning. Equilibrium strategies are dictated by the prior belief that the project is profitable: a high-ability agent plays a cutoff...

We study optimal redistributive taxation in an environment with asset price changes, adopting the modern finance view that asset prices fluctuate not...
