Stagflationary Stock Returns
We study investors’ perceptions of inflation through the lens of a high-frequency event study, documenting they have a stagflationary view of the world. In response to higher-than-expected inflation, investors expect firms’ nominal cash flows to remain stagnant while discount rates increase, resulting in lower stock prices. Both the equity risk premium and nominal risk-free yields rise, but longer-term real yields remain unchanged. Consistent with investors interpreting inflation as a cost shock, investors expect firms with low market power to suffer larger declines in cash flows. Cash ...

How Costly Is Rising Market Power for the U.S. Economy?
We survey the recent, active debate on market power in the U.S. economy. While typical studies on market power focused on narrow industries due to data constraints, the relevance of market power for the aggregate economy was reinvigorated by a study focusing on publicly traded firms that documented a significant rise in U.S market power since the 1980s. This article is meant to provide a bird's-eye view of the (sometimes heated) discussion on market power. Furthermore, we examine the macroeconomic consequences of a rise in U.S. market power.

How Do Supply Shocks to Inflation Generalize? Evidence From the Pandemic Era in Europe
We document how the interaction of supply chain pressures, elevated household inflation expectations, and firm pricing power contributed to the pandemic-era surge in consumer price inflation in the euro area. Initially, supply chain disruptions raised inflation, particularly in manufacturing, through a cost-push channel, while also elevating inflation expectations. In turn, higher inflation expectations appear to have lowered the price elasticity of consumer demand and strengthened firms’ pricing power, enabling even firms in service sectors that were initially unaffected by supply ...

New Estimates of the Lerner Index of Market Power for U.S. Banks
The Lerner index is widely used to assess firms' market power. However, estimation and interpretation present several challenges, especially for banks, which tend to produce multiple outputs and operate with considerable inefficiency. We estimate Lerner indices for U.S. banks for 2001-18 using nonparametric estimators of the underlying cost and profit functions, controlling for inefficiency, and incorporating banks' off-balance-sheet activities. We find that mis-specification of cost or profit functional forms can seriously bias Lerner index estimates, as can failure to account for ...

When Hosios Meets Phillips: Connecting Efficiency and Stability to Demand Shocks
In an economy with frictional goods and labor markets there exist a price and a wage that implement the constrained efficient allocation. This price maximizes the marginal revenue of labor, balancing a price and a trading effect on firm revenue, and this wage trades off the benefits of job creation against the cost of turnover in the labor market. We show under bargaining over prices and wages that a double Hosios condition: (i) implements the constrained efficient allocation; (ii) also minimizes the elasticity of labor market tightness and job creation to a demand shock, and; (iii) that the ...

The Origins of Market Power in DeFi
In our previous Liberty Street Economics post, we introduced the decentralized finance (DeFi) intermediation chain and explained how various players have emerged as key intermediaries in the Ethereum ecosystem. In this post, we summarize the empirical results in our new Staff Report that explains how the need for transaction privacy across the DeFi intermediation chain gives rise to intermediaries’ market power.

Dynamics of Market Power in Monetary Economies
We study the dynamic interplay between monetary policy and market power in a decentralized monetary economy. Building on Choi and Rocheteau (2024), our key innovation is to model rent seeking as a process that takes time, allowing market power to evolve gradually. Our model predicts that a gradual reduction in the nominal interest rate causes a simultaneous increase in rent-seeking effort and producers’ market power, consistent with the stylized correlation observed in the U.S. over the last few decades. Producer entry can however reverse this relation in the short run, and neutralize it in ...

Market Power, Inequality, and Financial Instability
Over the last four decades, the U.S. economy has experienced a few secular trends, each of which may be considered undesirable in some aspects: declining labor share; rising profit share; rising income and wealth inequalities; and rising household sector leverage and associated financial instability. We develop a real business cycle model and show that the rise of market power of the firms in both product and labor markets over the last four decades can generate all of these secular trends. We derive macroprudential policy implications for financial stability.

How Does Market Power Affect Fire-Sale Externalities?
An important role of capital and liquidity regulations for financial institutions is to counteract inefficiencies associated with “fire-sale externalities,” such as the tendency of institutions to lever up and hold illiquid assets to the extent that their collective actions increase financial vulnerabilities. However, theoretical models that study such externalities commonly assume perfect competition among financial institutions, in spite of high (and increasing) financial sector concentration. In this post, which is based on our forthcoming article, we consider instead how the effects ...
