Increased health care spending has been argued to be largely due to technological change. Cost-effectiveness analysis is the main tool used by private and public third-party payers to prioritize adoption of the new technologies responsible for this growth. However, such analysis by payers...

We present a framework for understanding the effects of automation and other types of technological changes on labor demand, and use it to interpret changes in US employment over the recent past. At the center of our framework is the allocation of tasks to capital and labor—the task content of...

Medical innovations have improved survival and treatment for many diseases but have simultaneously raised spending on health care. Many health economists believe that technological change is the major factor driving the growth of the heath care sector. Whether quality has increased as much as...

We examine the concerns that new technologies will render labor redundant in a framework in which tasks previously performed by labor can be automated and new versions of existing tasks, in which labor has a comparative advantage, can be created. In a static version where capital is fixed and...

We argue theoretically and document empirically that aging leads to greater (industrial) automation, and in particular, to more intensive use and development of robots. Using US data, we document that robots substitute for middle-aged workers (those between the ages of 36 and 55). We then show...

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...

This paper provides a theoretical and empirical examination of the long-run growth in weight over time. We argue that technological change has induced weight growth by making home- and market-production more sedentary and by lowering food prices through agricultural innovation. We analyze how...

The growth of the U.S. economy over the nineteenth century was characterized by a sharp acceleration in the rate of inventive activity and a dramatic rise in the relative importance of highly specialized inventors as generators of new technological knowledge. Relying on evidence compiled from...

The social value of an innovation is comprised of the value to consumers and the value to innovators. We estimate that for the HIV/AIDS therapies that entered the market from the late 1980's onwards, innovators appropriated only 5% of the social surplus arising from these new technologies....

Recent scholarly literature explains the spread of in-house research labs during the early 20th century by pointing to the information problems involved in contracting for technology. We argue that these difficulties have been overemphasized and that in fact a substantial trade in patented...
