We explore how firms grow by adding products. In contrast to most earlier work on the topic, our conceptual and empirical framework allows for separate treatment of product innovation (vertical differentiation) and diversification (horizontal differentiation). The market context is Japan's...

A market-size-only theory of industrialization cannot explain why England developed nearly two centuries before China. One shortcoming of such a theory is its exclusive focus on producers. We show that once we incorporate the incentives of factor suppliers' organizations such as craft guilds,...

Why was the Industrial Revolution successful at generating sustained growth? Some have argued that there was a fundamental change in the way that new technology was developed during this period, but evidence for this argument remains largely anecdotal. This paper provides direct quantitative...

Employing a sample of renowned U.S. inventors that combines biographical detail with information on the patents they received over their careers, we highlight the impact of early U.S. patent institutions in providing broad access to economic opportunity and in encouraging trade in new...

For those who think of Cleveland as a decaying rustbelt city, it may seem difficult to believe that this northern Ohio port was once a hotbed of high-tech startups, much like Silicon Valley today. During the late nineteenth and early twentieth centuries, Cleveland played a leading role in the...

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...

Family firms are typically associated with negative characteristics, including lower tendencies towards innovation, a higher risk of failure, and inefficiencies deriving from nepotism among family members, criticisms which are even greater when the company is handed over to a female relative....

The paper explores the role of institutional mechanisms in generating technological knowledge spillovers. The estimation is over panel datasets of patent grants, and unpatented innovations that were submitted for prizes at the annual industrial fairs of the American Institute of New York, during...

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...
