To celebrate, here is a fantastic monograph by Arthur on an extremely interesting topic

How does information shape monopoly outcomes under interdependent values? We characterize payoff sets across three classes of information structures. With no restrictions, buyers can obtain the entire surplus even though the seller chooses a price econtheory.org/ojs/index.ph...

Super cool

"Seller search for bidders and costly bidder entry jointly shape auction profitability, payoffs, and efficiency. Observability plays a key role."

Amazing paper with Siwen’s years of effort🥳

"Can communities sustain cooperation when players can add or erase signals from their records?
Sufficiently long-lived players can hardly sustain any cooperation, but players w/ intermediate lifespans can sustain some cooperation."

I don’t know if anyone actually sees this given that I never post but here it goes. If you see Iranians these days be a bit gentler with them. We are going through something horrific. Our nation is in the hand of a few individuals who don’t seem to care about anything other than having a useless

Can participants detect an authority straying from its announced rules? Transparency trades off with strategy-proofness, stability, and efficiency. Yet the paper finds partial guarantees: stability can be enforced, while efficiency usually cannot econtheory.org/ojs/index.ph...

How best to incentivise prompt disclosure? We formalise this question and show that the answer has a deadline structure. We apply our results to the design of unemployment insurance schemes econtheory.org/ojs/index.ph...

We’re happy to host the 1st European Economic Theory Conference in Bonn next fall! Submissions in all areas of economic theory are welcome.

Very useful result indeed! I learned it first time from Hörner-Samuelson 2011, where they give a counterexample of Cauchy distribution to show it is strictly weaker than log-concavity.

Why fund highly novel research? It can improve the evolution of knowledge by guiding future researchers. We propose a model in which researchers decide which questions to address and at what intensity to search for the answer based on existing knowledge. https://buff.ly/3Pxv5uk

We study comparative statics in adjustment-cost models. Comparative-statics conclusions may be drawn under very weak assumptions on costs, and this insight leads to a general Le Chatelier principle. We consider several applications. https://buff.ly/41U35sb
