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 costs
for unproduced products. Lower predicted costs imply
increased product adoption and identify which
firms enter when export demand rises, including firms
crossing broad product classifications. We use these
counterfactual costs to quantify how reductions in fixed
and
marginal costs induce product entry and lower price
indices. In a price-stabilization
exercise following a cost shock, entry subsidies can cost
less than subsidies to incumbents, particularly for
smaller shocks when capable potential entrants remain
available.
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.
