The broken ladder: AI, remote work, and early-career hiring

Is generative AI replacing junior workers? A growing literature answers yes, citing large declines in early-career hiring concentrated in GenAI-exposed occupations. We argue that this verdict is premature because GenAI e...Read more...

Liquidity as competitive advantage: the role of intangibles

We show that short-term liquidity can be a source of competitive advantage by enabling firms to invest in intangible assets. Our analysis leverages a French reform that capped payment delays in trade credit contracts, wh...Read more...

Do larger firms exert more market power? Markups and markdowns along the size distribution

Combining financial statements with firm-level product prices, we find that larger firms exhibit lower markups, although they are overcompensated by substantially higher wage markdowns. We explain our divergence from pri...Read more...

The price of power: Why rising markups hurt innovation and widen inequality

Over the past four decades, the US has seen rising market power, slowing productivity growth, and deepening wealth inequality. This column explores how declining competition may be the common culprit. Weak competition le...Read more...

Trade, skills and productivity

We examine how firms adjust their production and technology in response to exogenous trade shocks. We develop a model in which revenue TFP can be distinguished from quantity TFP, and where skill upgrading is explicitly e...Read more...

Fantastic beasts and where to find them

Fantastic beasts are magical creatures that cannot be seen unless one looks for them with the eye of the wizard, but that still play a significant role in the world. The fantastic beasts we hunt and find in the present p...Read more...

Regional productivity differences in the UK and France: from the micro to the macro

We propose a new data resource that attempts to overcome limitations of standard firm-level datasets for the UK (like the ARD/ABS) by building on administrative data covering the population of UK firms with at least one ...Read more...

Do larger firms exert more market power? Markups and markdowns along the size distribution

Several models posit a positive cross-sectional correlation between markups and firm size, which characterizes misallocation, factor shares, and gains from trade. Accounting for labor market power in markup estimation, w...Read more...

Globalization and market power

Economic theory suggests that the markup is a key measure of market power and that its relationship with trade is rich and complex. Trade liberalisation can reduce markups via a decline in the residual domestic demand bu...Read more...

Technology, market structure and the gains from trade

We study the gains from trade in a model with oligopolistic competition, heterogeneous firms and innovation. Our key finding is that a trade-induced increase in market concentration can be an important source of the gain...Read more...

Markups, intangible capital and heterogeneous financial frictions

This paper studies the interaction between financial frictions, intangible investment decisions, and markups at the firm level. In our model, heterogeneous credit constraints distort firms' decisions to invest in cost-re...Read more...

Poorly measured confounders are more useful on the left than on the right

Researchers frequently test identifying assumptions in regression based research designs (which include e.g. instrumental variables or differences-in-differences models) by adding additional control variables on the righ...Read more...

International buyers' sourcing and suppliers' markups in Bangladeshi garments

Large international buyers play a key role in global value chains. We exploit detailed transaction-level data on the usage of material inputs to study how Bangladeshi garment suppliers' markups vary across international ...Read more...

Technology, market structure and the gains from trade

We study the gains from trade in a new model with oligopolistic competition, firm heterogeneity, and innovation. Lowering trade costs reduces markups on domestic sales but increases markups on export sales, as firms do n...Read more...

Transparency about the outcomes of mental health services (IAPT approach): an analysis of public data

Background: Internationally, the clinical outcomes of routine mental health services are rarely recorded or reported; however, an exception is the English Improving Access to Psychological Therapies (IAPT) service, which...Read more...

Spatial frictions

The world is replete with spatial frictions. Shipping goods across cities entails trade frictions. Commuting within cities causes urban frictions. How important are these frictions in shaping the spatial economy? We deve...Read more...

Unraveling firms: demand, productivity and markups heterogeneity

We develop a novel framework that simultaneously allows recovering heterogeneity in demand, quantity TFP and markups across firms while leaving the correlation between the three dimensions unrestricted. We accomplish thi...Read more...

Preferences for fair prices, cursed inferences, and the nonneutrality of money

This paper explains the nonneutrality of money from two assumptions: (1) consumers dislike paying prices that exceed some fair markup on firms? marginal costs; and (2) consumers under infer marginal costs from available ...Read more...

The Enduring Impact of Childhood Experience on Mental Health: Evidence Using Instrumented Co-Twin Data

The question of whether there is a lasting effect of childhood experience on mental health has eluded causal measurement. We draw upon identical twin data and econometric instrumentation to provide an unbiased answer. We...Read more...

Agricultural Returns and Conflict: Quasi-Experimental Evidence from a Policy Intervention Programme in Rwanda

In 1997 Rwanda introduced a re-settlement policy for refugees displaced during previous conflicts. We exploit geographic variation in the speed of implementation of this policy to investigate the impact of conflict-induc...Read more...
