Who Can Produce What? Firm Capabilities and Product Entry
(with Luca
Macedoni and Vlad
Tyazhelnikov)
Which firms supply which products?
Modeling multi-product firms under heterogeneous markups, we
recover firms costs for produced products and develop an algorithm
inspired by recommender systems to predict them for unproduced
products. Lower predicted costs imply increased product adoption
and explain which firms supply products when export demand induces
domestic entry. The rich counterfactuals provided by the algorithm
enable new quantifications of shocks and policy effects. In a
price stabilization exercise following a cost shock, we find entry
subsidies often cost less than subsidies to incumbents, but less
frequently as shocks grow and capable entrants become scarce.
Can Firm Subsidies Spread Growth? (new
version coming soon)
(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.
