Markups, Pass-Through, and Firm Heterogeneity with Sequentially Mixed Search Staff Working Paper 2025-7 Alex Chernoff, Allen Head, Beverly Lapham Market power and pass-through of cost and demand shocks are studied in a market with free entry of heterogeneous firms and consumer mixed search. Equilibrium prices and markups are driven by variation in the elasticity of demand across firms. Improved conditions for buyers can either raise or lower market power.

Consumer Credit Regulation and Lender Market Power Staff Working Paper 2024-36 Zachary Bethune, Joaquín Saldain, Eric R. Young We investigate the welfare consequences of consumer credit regulation in a dynamic, heterogeneous-agent model with endogenous lender market power. Lenders post credit offers and borrowers—some informed and others uninformed—apply for credit. We calibrate the model to match characteristics of the unsecured consumer credit market and use the calibrated model to evaluate interest rate ceilings.

Markups and Inflation in Oligopolistic Markets: Evidence from Wholesale Price Data Staff Working Paper 2024-20 Patrick Alexander, Lu Han, Oleksiy Kryvtsov, Ben Tomlin We study how the interaction of market power and nominal price rigidity influences inflation dynamics. We find that pass-through declines with price stickiness when markets are concentrated, which implies a lower slope of the New Keynesian Phillips curve.

Trade and Market Power in Product and Labor Markets Staff Working Paper 2021-17 Gaelan MacKenzie Trade liberalizations increase the sales and input purchases of productive firms relative to their less productive domestic competitors. This reallocation affects firms’ market power in their product and input markets. I quantify how the labour market power of employers affects the distribution and size of the gains from trade.

Non-competing Data Intermediaries Staff Working Paper 2020-28 Shota Ichihashi I study a model of competing data intermediaries (e.g., online platforms and data brokers) that collect personal data from consumers and sell it to downstream firms.

Information Sharing and Bargaining in Buyer-Seller Networks Staff Working Paper 2016-63 Sofia Priazhkina, Frank H. Page This paper presents a model of strategic buyer-seller networks with information exchange between sellers. Prior to engaging in bargaining with buyers, sellers can share access to buyers for a negotiated transfer. We study how this information exchange affects overall market prices, volumes and welfare, given different initial market conditions and information sharing rules.

Uncertain Costs and Vertical Differentiation in an Insurance Duopoly Staff Working Paper 2014-14 Radoslav Raykov Classical oligopoly models predict that firms differentiate vertically as a way of softening price competition, but some metrics suggest very little quality differentiation in the U.S. auto insurance market.

Cross-border Mergers and Hollowing-out Staff Working Paper 2009-30 Oana Secrieru, Marianne Vigneault The purpose of our paper is to examine the profitability and social desirability of both domestic and foreign mergers in a location-quantity competition model, where we allow for the possibility of hollowing-out of the target firm. We refer to hollowing-out as the situation where the target firm is shut down following a merger with a domestic or foreign acquirer.
