This paper examines how international flows of technological knowledge affect economic performance across industries and firms in different countries. Motivated by the large share of the world's technology investments made by firms that are active across borders, we focus on international trade...

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...

We study the importance of technology and institutions in determining the size of markets in five different countries and fifteen different German states. The setting of 19th century Europe presents a unique opportunity to address this issue, since it witnessed fundamental change in both...

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...

We estimate and compare the production structures of the US, Japanese, and Korean total manufacturing sectors for the 1974-1990 period. We employ a translog variable cost function that includes such inputs as labor, materials, physical and R&D capital with the physical and R&D capital treated as...

The objectives of this preliminary study are threefold. The first is to analyze empirically the production structure of the Bell System at the aggregate level. Particular attention is focused on the pattern of substitution among the factor inputs and the degree to which the aggregate production...

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...

The paper analyzes the production structure and the demand for inputs in three major industrialized countries, the U.S., Japan and Germany. A dynamic factor demand model with two variable inputs (labor and energy)and two quasi-fixed inputs (capital and R&D) is derived directly from an...

I discuss the concept and empirical importance of international technology diffusion from the point of view of recent work on endogenous technological change. In this literature, technology is viewed as technological knowledge. I first review the major concepts, and how international technology...
