The Review of Economic Studies is one of the core journals in economics. It is essential reading for economists, consistently ranking among the top five journals.

Unemployment differentials are greater between countries in the euro area than between U.S. states. In both regions, net migration responds to unemployment differentials, though the response is smaller in the euro area compared to the United States. We use a multi-country DSGE model with cross-border migration to quantify Mundell’s hypothesis that labor mobility could substitute for independent monetary policy in a currency union.

Normal-form two-player games are categorized by players into K analogy classes so as to minimize the prediction error about the behavior of the opponent. This results in Clustered Analogy-Based Expectation Equilibria in which strategies are analogy-based expectation equilibria given the analogy partitions and analogy partitions minimize the prediction errors given the strategies.

We study a bargaining game in which a seller can trade with one of two buyers, who have values h and l (h > l). The outside option principle (OOP) predicts that the seller trades with the high-value buyer with probability converging to 1 at a price converging to max(h/2, l) as players become patient. While this prediction is supported by the Markov perfect equilibrium (MPE), a wide range of trading outcomes may emerge in subgame perfect equilibria (SPEs): in the patient limit, the seller can obtain any price in the interval [h/2, h] (and no other); moreover, allocative inefficiency and costly delay are possible.

Auction models are convenient abstractions of informal price-formation processes that arise in markets for assets or services. These processes involve frictions like bidder recruitment costs for sellers, participation costs for bidders, and limitations on sellers’ commitment abilities. This paper develops an auction model that captures such frictions.

We formulate a tractable model of pricing under directed search with heterogeneous firm demands. Demand characteristics drive bids in a position auction and enable us to bridge insights from the ordered search literature to those in the position auction literature. Equilibrium pricing implies that the marginal consumer’s surplus decreases down the search order, so consumers optimally follow the firms’ position ordering. A firm suffers from “business stealing” by firms that precede it and “search appeal” from subsequent firms.

We revisit the recent revealed preference analysis of sophisticated quasi-hyperbolic consumers by Blow, Browning, and Crawford (2021) (BBC). We show that BBC’s revealed preference test is too lax. There are non-rationalizable data that would pass their test. A basic problem with their test is that it requires finding a certain endogenous elasticity, without regard to the rationalizing utility. Their approach motivates a more stringent test, also based on first-order conditions, that would connect the endogenous elasticity and utility: We show that this test is also too lax.
