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...

Immigration, female labour supply and local cultural norms

We study the local evolution of female labour supply and cultural norms in West Germany in reaction to the sudden presence of East Germans who migrated to the West after reunification. These migrants grew up with high ra...Read more...

The impact of regulation on innovation

We present a framework that can be used to assess the equilibrium impact of regulation on endogenous innovation with heterogeneous firms. We implement this model using French firm-level panel data, where there is a sharp...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...

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...

The comparative advantage of firms

Resource-based theories propose that firms grow by diversifying into products that use common capabilities. We provide evidence for common-input capabilities, using a policy that removed entry barriers in input markets t...Read more...
