Can Innovation Help U.S. Manufacturing Firms Escape Import Competition from China?
Published: 06/05/2018 | DOI: 10.1111/jofi.12691
JOHAN HOMBERT, ADRIEN MATRAY
We study whether R&D‐intensive firms are more resilient to trade shocks. We correct for the endogeneity of R&D using tax‐induced changes to R&D costs. While rising imports from China lead to slower sales growth and lower profitability, these effects are significantly smaller for firms with a larger stock of R&D (about half when moving from the bottom quartile to the top quartile of R&D). We provide evidence that this effect is explained by R&D allowing firms to increase product differentiation. As a result, while firms in import‐competing industries cut capital expenditures and employment, R&D‐intensive firms downsize considerably less.
News Trading and Speed
Published: 05/21/2015 | DOI: 10.1111/jofi.12302
THIERRY FOUCAULT, JOHAN HOMBERT, IOANID ROŞU
We compare the optimal trading strategy of an informed speculator when he can trade ahead of incoming news (is “fast”), versus when he cannot (is “slow”). We find that speed matters: the fast speculator's trades account for a larger fraction of trading volume, and are more correlated with short‐run price changes. Nevertheless, he realizes a large fraction of his profits from trading on long‐term price changes. The fast speculator's behavior matches evidence about high‐frequency traders. We predict that stocks with more informative news are more liquid even though they attract more activity from informed high‐frequency traders.
Can Unemployment Insurance Spur Entrepreneurial Activity? Evidence from France
Published: 01/22/2020 | DOI: 10.1111/jofi.12880
JOHAN HOMBERT, ANTOINETTE SCHOAR, DAVID SRAER, DAVID THESMAR
We evaluate the effect of downside insurance on self‐employment. We exploit a large‐scale reform of French unemployment benefits that insured unemployed workers starting businesses. The reform significantly increased firm creation without decreasing the quality of new entrants. Firms started postreform were initially smaller, but their employment growth, productivity, and survival rates are similar to those prereform. New entrepreneurs' characteristics and expectations are also similar. Finally, jobs created by new entrants crowd out employment in incumbent firms almost one‐for‐one, but have a higher productivity than incumbents. These results highlight the benefits of encouraging experimentation by lowering barriers to entry.
