Optimal Allocation with Noisy Inspection [draft] [slides]

In a standard principal-agent allocation model, endow the agent with a noisy private signal about the principal's return and allow the principal to inspect the return at a cost. The inspection and allocation mechanism that maximizes the principal's expected return without the use of transfers describes optimal inspection as both an exploration and a screening tool. This relates to many important applied settings including employer hiring strategies, public grant mechanisms and portfolio investment rules.

• Optimal Allocation with Noisy Verification [companion piece]

This article shows that the results from Optimal Allocation with Noisy Inspection analogously apply to a setting where agents have perfect information but verification of types is noisy.

Strategic Private Exploration [abstract] [draft forthcoming]

In a strategic exploration game, multiple players determine the order in which they explore unknown options with the objective of maximizing the sum of discovered rewards. Exploration is private in the sense that players cannot condition the order in which they explore on their competitor's decisions. Equilibrium exploration procedures are determined, and losses characterized as a function of how the rewards are split when simultaneously explored. This informs us about many areas of policy design including patent and copyright regimes, R&D tournaments, and competition regulation.

Sequential Information Acquisition and Optimal Search w/ Rakesh Vohra [abstract] [draft forthcoming]

Consider the principal-agent allocation model from Optimal Allocation with Noisy Inspection, and suppose there are now many agents, each with a noisy signal of the principals return from allocating to them. The inspection and allocation mechanism that maximizes the principal's expected return now sequentially searches through the agents in a way that incentivises truthful reports . This essentially generalises Optimal Allocation with Noisy Inspection to many agents and Ben-Porath, Dekel, Lipman (2014) to noisy types.

• Pandora's Linear Program [companion piece]

This article maps Weitzman's canonical search problem into a linear program. This allows us to re-derive existing results concerning optimal search and extend them to problems pertaining to strategic search, information acquisition, index manipulation and robust search.
