Can Firm Subsidies Spread Growth?

(with Elodie Andrieu)

How do firms diffuse resources along the value chain and how large are such spillovers? We estimate the effects of France’s R\&D subsidies during a period of substantially increased funding, using increased access from consultancy certification as an instrument. While most studies focus on manufacturing, over half of the treated firms are in services. Subsidies increase local industry technical employment with an elasticity of .12 and firms with an elasticity of .05. Subsidies also increase local upstream employment with an elasticity of .05 but downstream employment asymmetrically, twice as large as upstream but with almost zero effect on technical employment. This suggests directed innovation spillovers along the value chain. 


Firms in Product Space

(with Luca Macedoni and Vlad Tyazhelnikov)    

Which products are efficiently produced together and which firms supply which products? Modeling multi-product firms under variable markups, we estimate firms' absolute advantages for produced products and develop an algorithm to predict them for unproduced products. Better advantages imply increased product adoption and explain which firms supply products when export demand induces domestic adoption. Predicted advantages and markups imply measures of Revenue and Competition Potential which explain firm sales and scope growth. If all firms produced all potential products, consumer welfare could increase by 16-30% under constant markups, rising to 46-86% under variable markups.
