During World War II Americans were called upon repeatedly to salvage raw materials for the war effort, often during brief, highly publicized quot;drives.quot; Stories about the salvage drives are a staple in both popular and scholarly histories of the home front, and in film documentaries,...

Several recent theories emphasize the negative effects of an aging population on economic growth, either because of the lower labor force participation and productivity of older workers or because aging will create an excess of savings over desired investment, leading to secular stagnation. We...

How did the diffusion of the internet affect regional wage inequality? We examine the relationship between business use of advanced internet technology and local variation in US wage growth between 1995 and 2000. We find no evidence that the internet contributed to regional wage convergence....

Will smart machines do to humans what the internal combustion engine did to horses – make them obsolete? If so, can putting people out of work or, at least, good work leave them unable to buy what smart machines produce? Our model's answer is yes. Over time and under the right conditions,...

As robots and other computer-assisted technologies take over tasks previously performed by labor, there is increasing concern about the future of jobs and wages. We analyze the effect of the increase in industrial robot usage between 1990 and 2007 on US local labor markets. Using a model in...

We present a task-based model in which high- and low-skill workers compete against machines in the production of tasks. Low-skill (high-skill) automation corresponds to tasks performed by low-skill (high-skill) labor being taken over by capital. Automation displaces the type of labor it directly...

According to unpublished data compiled by BLS, productivity in the construction industry reached a peak in 1968 and, except for a brief and small upturn between 1974 and 1976, has been falling ever since. This paper examines the sources of this productivity decline between 1968 and 1978 by...

The 21st century global decline in productivity growth is not well understood. One possible contributor is a decline in economic dynamism. We explore the contribution of firm formation and employee movement to productivity using administrative data on the population of New Zealand construction...

This paper examines the difference in productivity between union and nonunion contractors in the construction industry over a sample of 83 commercial office buildings and another sample of 68 elementary and secondary schools. The popular belief that the building trades unions reduce productivity...

Previous studies using micro data to estimate the impact of unions on productivity in construction in the early 1970's have found productivity to be higher for union than nonunion contractors in the private sector. The validity of these studies has been questioned in light of the declining...
