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 R&D Subsidies Spread Growth?
(with Elodie Andrieu)
Do R&D subsidies spread growth beyond recipient firms? We study France’s Crédit d’Impôt Recherche, exploiting quasi-experimental variation in subsidy access generated by the certification of R&D consultancies. IV estimates show that subsidies increase technical employment with an elasticity of .16, technical wages with an elasticity of .14 and non-technical employment with an elasticity of .09, pointing to increased demand for technical workers. This spreads along the value chain to unsubsidized firms, where employment responses for technical workers are half as large as the direct effects, spreading growth and innovation related activity.
