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...

Very useful result indeed! I learned it first time from HΓΆrner-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
