We use comprehensive micro data in the French manufacturing sector between 1995 and 2017 to document the effects of a fall in the cost of investments in modern manufacturing capital, including modern automation technologies, on employment, wages, sales, prices, and business stealing. Causal effects are estimated with event studies and a shift-share IV design leveraging pre-determined supply linkages and productivity shocks across foreign suppliers of manufacturing capital. At all levels of analysis - plant, firm, and industry - the estimated impact of capital investments on employment is positive, even for unskilled industrial workers. Further-more, we find that capital investments lead to higher sales and exports, higher profits, and lower consumer prices, while wages and wage inequality remain unchanged. We estimate a positive industry-level employment response to manufacturing capital investments only in industries that are exposed to import competition, due to business-stealing across countries. Thus, typical investments in modern manufacturing capital lead to an increase in domestic labor demand and promote competitiveness in international markets.
