Will industries use new information technologies to eliminate jobs? Sometimes productivity-enhancing technology increases industry employment instead. In manufacturing, jobs grew along with productivity for a century or more; only later did productivity gains bring declining employment. What changed? Markets became saturated.
Artificial intelligence (AI) technologies will automate many jobs, but the effect on employment is not obvious. Although technology has sharply reduced jobs in manufacturing in recent decades, for over a century before that, employment grew, even in industries experiencing rapid technological change. This paper presents a simple model of the change in demand that accurately predicts the rise and fall of employment in the textile, steel and automotive industries, and will be useful for exploring how AI is likely to affect jobs over the next 10 or 20 years.
Since the 1980s, US industries have become increasingly dominated by large firms across almost all sectors. Why? One possibility is that large firms have become dominant because antitrust authorities have allowed too many mergers and acquisitions. James Bessen explores another possibility: that leading firms have been better at harnessing information technology (IT) for competitive advantage, allowing them to grow faster.
