Resumen de Technical Change and the Demand for Skills during the Second Industrial Revolution: Evidence from the Merchant Marine, 1891-1912
Aimee Chin, Chinhui Juhn, Peter Thompson
Using a large, individual-level wage data set, we examine the impact of a major technological innovation-the steam engine-on the demand for skills in the merchant shipping industry. We find that the technical change created a new demand for engineers, a skilled occupation. It had a deskilling effect on production work-moderately skilled able-bodied seamen were replaced by unskilled engine room operatives. On the other hand, able-bodied seamen, carpenters, and mates employed on steam vessels earned a premium relative to their counterparts on sail vessels, and this appears partly related to skill.
