Telephone operation, one of the most common jobs for young American women in the early 1900s, provided hundreds of thousands of female workers a pathway into the labor force. Between 1920 and 1940, AT&T adopted mechanical switching technology in more than half of the U.S. telephone network,...

We study a dynamic general equilibrium model where innovation takes the form of the introduction new goods, whose production requires skilled workers. Innovation is followed by a costly process of standardization, whereby these new goods are adapted to be produced using unskilled labor. Our...

We examine the impact of individual-level motives upon innovative effort and performance in firms. Drawing from economics and social psychology, we develop a model of the impact of individuals' motives and incentives upon their innovative effort and performance. Using data on over 11,000...

Technological change was unskilled-labor-biased during the early Industrial Revolution of the late eighteenth and early nineteenth centuries, but is skill-biased today. This fact is not embedded in extant unified growth models. We develop a model of the transition to sustained economic growth...

Innovation in the U.S. economy is about employing and rewarding highly talented workers to produce new products. Using unique longitudinal matched employer-employee data, this paper makes a key connection between talent and firms in markets with risky product innovations. We show that software...

We examine whether startups attract employees with different pecuniary and non-pecuniary motives than small or large established firms. We then explore whether such differences in employee motives lead to differences in innovative performance across firm types. Using data on over 10,000 U.S. R&D...

Recent medical research shows that health is highly influential for learning and the ability to think laterally; however, past economic studies have failed to empirically examine the influence of health on learning, schooling, and ideas production; the main drivers of growth in endogenous growth...

During the Industrial Revolution technological progress and innovation became the main drivers of economic growth. But why was Britain the technological leader? We argue that one hitherto little recognized British advantage was the supply of highly skilled, mechanically able craftsmen who were...

Worker mobility across firms can enhance innovation by spreading knowledge, but such mobility may also hinder innovation by making firms reluctant to invest in R&D. A common way that firms limit workers' mobility is with noncompete agreements (NCAs). We examine how the legal enforceability of...
