Can Firm Subsidies Spread Growth?

(with Elodie Andrieu)

How do firms diffuse resources and do they spillover outside headquarter intensive areas?  We show R&D subsidies induce French firms to hire new workers, often in new establishments and commuting zones.  Using subsidy induced labor demand shocks and past employment patterns, we estimate a within industry spillover elasticity of .26 to non-subsidy firms, rising to .35 for openings outside of headquarter areas.  Spillovers are also significant across firm branches and for firms. While subsidies are nominally awarded to headquarters, firms expand to distribute spillovers more broadly.


Firms in Product Space: Adoption, Growth, and Competition

(with Luca Macedoni and Vlad Tyazhelnikov)    

Which products are potentially produced together? When demand for a product increases, which firms will supply it? Using multi-product production patterns within and across firms, we recover a continuous cost-based distance between firms and unproduced products. Higher product distance implies decreasing adoption frequency.  When export demand induces domestic product adoption, closer firms provide this supply.  Potential costs imply measures of Revenue  and Competition Potential. These predict firm sales and scope growth.  If all firms produced all products linked by co-production, consumer welfare could increase by 16-30% under constant markups, rising to 46-86% under variable markups.
