Quasi-Concavity, Convexity of Optimal Actions, and the Local Single-Crossing Property
Kailin Chen
This note presents two results. First, it shows that under mild conditions, a decision problem is quasi-concave if the set of optimal actions is convex under every belief. Second,…
Collective Experimentation with Correlated Payoffs
Kailin Chen
This paper studies an exponential bandit model in which a group of agents collectively decide whether to undertake a risky action . This action is implemented if the fraction of…
Communication as Voting
Kailin Chen
This paper studies information aggregation in informal elections by examining a cheap-talk model with multiple senders and one receiver. Each sender observes a noisy private signal…
Ranking Statistical Experiments via the Linear Convex Order and the Lorenz Zonoid: Economic Applications
Kailin Chen
This paper introduces a novel ranking of statistical experiments, the linear-Blackwell (LB) order, which can equivalently be characterized by (i) the dispersion of the induced post…
