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...

Creative destruction through innovation bursts

In theories of creative destruction, product innovation is a key driver of aggregate growth. In this paper, we confront the predictions of these theories about product dynamics with empirical patterns in product-level da...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...

Lobbying for globalisation

Using detailed information from lobbying reports filed under the Lobbying Disclosure Act, we construct a unique dataset that allows us to identify which firms lobby on Free Trade Agreements (FTAs) negotiated by the Unite...Read more...

All aboard: the effects of port development

Seaports facilitate the fast flow of goods across space, but ports also entail local costs borne by host cities. We use the introduction of containerized shipping to explore the effects of port development. At the local ...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...

Endogenous mobility in pandemics: theory and evidence from the United States

We study infectious diseases in a spatial epidemiology model with forward-looking individuals who weigh disease environments against economic opportunities when moving across regions. This endogenous mobility allows regi...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...

CEP discussion paper

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...

Endogenous cross-region human mobility and pandemics

We study infectious diseases using a Susceptible-Infected-Recovered-Deceased model with endogenous cross-region human mobility. Individuals weigh the risk of infection against economic opportunities when moving across re...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...

Global banking: endogenous competition and risk taking

When banks expand abroad, their riskiness decreases if foreign expansion happens in destination countries that are more competitive than their origin countries. We reach this conclusion in three steps. First, we develop ...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...

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...

Global banking: risk taking and competition

Direct involvement of global banks in local retail activities can reduce risk-taking by promoting local competition. We develop this argument through a model in which multinational banks operate simultaneously in differe...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...

Stagnation traps

We provide a Keynesian growth theory in which pessimistic expectations can lead to very persistent, or even permanent, slumps characterized by unemployment and weak growth. We refer to these episodes as stagnation traps,...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...

Dynamic selection: an idea flows theory of entry, trade and growth

Trapped factors and China's impact on global growth

When China?s accession to the WTO exposed European firms to import competition, they responded by increasing their investment in innovation. This response was stronger in industries and firms where factors of production ...Read more...

The financial resource curse

This paper presents a model of financial resource curse, i.e. episodes of abundant access to foreign capital coupled with weak productivity growth. We study a two-sector, tradable and non-tradable, small open economy. Th...Read more...

Where is the Economics in Spatial Econometrics?

Spatial econometrics has been criticized by some economists because some model specifications have been driven by data-analytic considerations rather than having a firm foundation in economic theory. In particular this a...Read more...

An R&D-Based Model of Multi-Sector Growth
