Information and Market Power in DeFi Intermediation
This paper considers the “DeFi intermediation chain”—the market structure that underlies the creation and distribution of ETH, the native cryptocurrency of Ethereum—to examine how information asymmetry shapes intermediation rents. We argue that using proof-of-stake blockchain technology in DeFi leads to a novel limit to arbitrage, arising from the tension between arbitrageurs’ privacy needs and blockchain transparency. Using a new dataset which distinguishes private and public transactions in Ethereum, we find that a one percent increase in private information advantage leads to a ...

An Analysis of Revenues at the Comédie française, 1680-1793
I study the business practices of the Comdie franaise, the main theater in Paris, between 1680 and 1793. The theater was an actors? partnership and operated within a (contested) oligopoly. Newly available data provide revenues by price category for over 32,000 performances. Attendance varied considerably from one performance to the next. Total revenues increased in the second half of the 18th century as demand for entertainment in Paris boomed. The increase came in part from box rentals (by performance or by season). Pricing practices changed over time, as premium pricing for high-demand ...

Market Structure and Monetary Non-neutrality
I propose an equilibrium menu cost model with a continuum of sectors, each consisting of strategically engaged firms. Compared to a model with monopolistically competitive sectors that is calibrated to the same data on good-level price flexibility, the dynamic duopoly model features a smaller inflation response to monetary shocks and output responses that are more than twice as large. The model also implies (i) four times larger welfare losses from nominal rigidities, (ii) smaller menu costs and idiosyncratic shocks are needed to match the data, (iii) a U-shaped relationship between market ...
