Firms in
Product Space: Adoption, Growth, and Competition
(with Luca
Macedoni and Vlad
Tyazhelnikov)
Which products are potentially produced
together? Can any firm eventually supply any new demand? Using
multi-product production costs within and across firms, we recover
a continuous cost based distance between products and firms.
Product distance implies a product adoption path, with distance
decreasing adoption frequency. When export demand induces
domestic product adoption, closer firms provide this supply.
Counterfactual production costs imply measures of Revenue
Potential and Competition Potential. These predict firm sales
growth, scope growth and core focus. If all firms produced all
products linked by co-production, consumer welfare would increase
by 10-30%.
Multi-establishment
Firm Structure, Subsidies and Spillovers
(with Elodie Andrieu)
How
do firms distribute resources internally, and does this result
in spillovers far from headquarters? We describe French
Multiple Establishment firm structure and show subsidies induce
firms to hire new workers, mainly in new establishments and
often in new commuting zones, with little evidence of
reallocation. The most hiring responsive occupations are
techies and support workers in line with R&D targeting. We
estimate an employment spillover elasticity of .12 at the
commuting zone level within industry and spillovers on the
number of establishments, but weak effects in the commuting
zone. Dispersed industries have half this elasticity and
concentrated industries twice this elasticity. While subsidies
may be given to headquarters in high-skill advanced areas, firms
redistribute employment and spillovers more broadly.
