We survey aspects of the intellectual development of the economics of information from the 1970s to today. We focus here on models where information is communicated indirectly through actions. Basic results, such as the failure of the fundamental theorems of welfare economics, the non-existence...

The paper surveys the recent work on economics of information with endogenous information structures where individuals can directly communicate information with each other. We consider the theoretical work on cheap talk, Bayesian persuasion, and information design, and review the implications of...

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...

Liquidity management is key in industries with variable cash flows. We study how businesses in the highway construction industry manage cash flow by strategically bidding more on work with an earlier payout--a practice known as front-end loading. We find that small contractors, infrequent...

Blockchain consensus is a state whereby each node in a network agrees on the current state of the blockchain. Existing protocols achieve consensus via a contest or voting procedure to select one node as a dictator to propose new blocks. However, this procedure can still lead to potential attacks...

Principal-agent models take outside options, determining participation and incentive constraints, as given. We construct a general equilibrium model where workers' reservation wages and the maximum punishment acceptable before workers quit are instead determined endogenously. We simultaneously...

In a market with symmetric information about fundamentals, can information-based trade still arise? Consider bond and FX markets, where private information about nominal cash flows is generally absent, but participants are convinced that superior information exists. We analyze a class of...

We propose a broad measure of liquidity for the overall financial market by exploiting its connection with the amount of arbitrage capital in the market and the potential impact on price deviations in US Treasurys. When arbitrage capital is abundant, we expect the arbitrage forces to smooth out...
