I study a market in which a profit-maximizing intermediary facilitates trade between buyers and sellers. The intermediary sets prices for buyers and sellers, and keeps the difference as her fee. Optimal prices increase with demand and, under plausible conditions, the optimal percent fee...

In this paper, we study a new channel to explain firms' price setting behavior. We propose that uncertainty about factor prices has a positive effect on markups. We show theoretically that firms with higher shares of inputs with volatile prices set higher markups. We use the Bartik shift-share...

We develop a dynamic asset pricing model of cryptocurrencies/tokens that allows users to conduct peer-to-peer transactions on digital platforms. The equilibrium value of tokens is determined by aggregating heterogeneous users' transactional demand rather than discounting cash flows, as is done...

We study revenue volatility of a monopolist selling a divisible good to consumers in the presence of local network externalities among consumers. Each consumer's utility depends on her consumption level as well as the consumption levels of her neighbors in a network through network...

We study the performance of different regulatory approaches for the expansion of electricity transmission networks in the light of realistic demand patterns and fluctuating wind power. In particular, we are interested in the relative performance of a combined merchant-regulatory mechanism...
