We apply an understanding of what computers do -- the execution of procedural or rules-based logic -- to study how computer technology alters job skill demands. We contend that computer capital (1) substitutes for a limited and well-defined set of human activities, those involving routine...

Several recent published papers have asserted that a growing proportion of workers with college degrees are either unemployed or employed in jobs requiring only high school skills. Using data from the 1980 and 1990 Censuses of Population and Housing, we show that this assertion does not...

Using data from two longitudinal surveys of American high school seniors, we show that basic cognitive skills had a larger impact on wages for 24-year-old men and women in 1986 than in 1978. For women, the increase in the return to cognitive skills between 1978 and 1986 accounts for all of the...

We describe how a single technological innovation, the introduction of image processing of checks, led to distinctly different changes in the structure of jobs in two departments of a large bank overseen by one group of managers. In the downstairs deposit processing department, image processing...

For a variety of reasons described in the paper, improving the performance of urban school districts is more difficult today than it was several decades ago. Yet economic and social changes make performance improvement especially important today. Two quite different bodies of research provide...

I survey the evidence on patterns in U.S. high school graduation rates over the period 1970-2010 and report the results of new research conducted to fill in holes in the evidence. I begin by pointing out the strengths and limitations of existing data sources. I then describe six striking...

We provide a comprehensive view of widening income inequality in the United States contrasting conditions since 1980 with those in earlier postwar years. We argue that the income distribution in each period was strongly shaped by a set of economic institutions. The early postwar years were...

Nominally free, unrestricted training in portable computer skills is offered by the majority of U.S. temporary help supply (THS) establishments, a practice that is inconsistent with the competitive model of training. This paper asks why temporary help firms provide free general skills training....

The U.S. temporary help services (THS) industry grew at 11 percent annually between 1979 to 1995, five times more rapidly than non-farm employment. Contemporaneously, courts in 46 states adopted exceptions to the common law doctrine of employment at will that limit employers' discretion to...

Labor Market Intermediaries (LMIs) are entities or institutions that interpose themselves between workers and firms to facilitate, inform, or regulate how workers are matched to firms, how work is accomplished, and how conflicts are resolved. This paper offers a conceptual foundation for...
