Recent models and empirical work on network formation emphasize the importance of propinquity in producing strong interpersonal connections. Yet, one might wonder how deep such insights run, as thus far empirical results rely on survey and lab-based evidence. In this study, we examine...

How do children affect women in science? We investigate this question using rich biographical data, linked with patents and publications, for 83,000 American scientists in 1956 at the height of the baby boom. Our analyses reveal a unique life-cycle pattern of productivity for mothers. While...

Good health is important for employment at older ages. However, little is known about how health-related functional abilities interact with occupational demands to shape work capacity. Using new data, we quantify individuals' functional abilities, combine that information with...

Using panel data from 23 OECD countries, I document that wages grow more over the life-cycle in countries where job-to-job mobility is more common. A life-cycle theory of job shopping and accumulation of skills on the job highlights that a more fluid labor market allows workers to faster...

We construct new technology indicators using textual analysis of patent documents and occupation task descriptions that span almost two centuries (1850-2010). At the industry level, improvements in technology are associated with higher labor productivity but a decline in the labor share....

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...

This paper identifies three major periods: 1900-1929, 1929-1965, and 1965-1978. In contrast to the middle period, the extreme periods are characterized by rapid growth in private employment and hours worked; because growth in private productivity increases by less, measured labor productivity...

The American Northeast industrialized rapidly from about 1820 to 1850, while the South remained agricultural. Industrialization in the Northeast was substantially powered during these decades by female and child labor, who comprised about 45% of the manufacturing work force in 1832. Wherever...

This paper examines the relationship between inflation, exchange rates, and the pattern of international trade and payments in a small economy with utility-maximizing agents and a transactions demand for money. Fully anticipated inflation has real effects in the model through its role as a tax...
