We study how changes to the informativeness of signals in Bayesian games and single-agent decision problems affect the distribution of equilibrium actions. Focusing on supermodular environments, we provide conditions under which a more precise private signal for one agent leads to an...

We study how information affects equilibria and welfare in games. For an agent, more precise information about an unknown state of the world leads to a mean-preserving spread of beliefs. We provide necessary and sufficient conditions to obtain either a non-increasing mean or a...

I consider a moral hazard problem with risk neutral parties, limited liability, and an informed principal. The contractible outcome is correlated to both the principal's private information and the agent's hidden action. In contrast to a model without a privately informed principal or without...

This appendix is divided into two sections. Appendix A covers several extensions of the basic search model in Section 1 of Mekonnen (2018). In particular, it contains additional results on frictional search, non-scarcity, hybrid search protocol with coarse information, and taste heterogeneity....

This paper studies how different search protocols affect social welfare in a search market with scarcity. Agents search for objects that differ in quality either through a random or a directed search protocol. Random search protocol, in which agents are randomly paired to an object of any...

We study how changes to the informativeness of signals in Bayesian games and single‐agent decision problems affect the distribution of equilibrium actions. Focusing on supermodular environments, we provide conditions under which a more precise private signal for one agent leads to an...

I study a continuous time principal-agent model in which an unknown parameter and the agent's hidden effort affect the distribution of observable outcomes. The principal and the agent learn about the parameter by observing past outcomes. The agent's current effort has an implicit long-term...

This supplementary appendix covers all the proofs that were skipped from the text or the appendix of Bayesian Comparative Statics (Mekonnen and Leal-Vizcaino, 2018). In particular, the proof for Corollary 1, Proposition 3, Theorem 2, and Theorem 3 are contained in this document. Several...

We study how changes to the informativeness of signals in Bayesian games and single-agent decision problems affect the distribution of equilibrium actions. A more precise private signal about an unknown state of the world leads to an mean-preserving spread of an agent's beliefs. Focusing on...
