Abstract

The mean duration of unemployment has approximately doubled in the U.S. between the early 1950s and the mid-1990s, with most of the increase occurring since the early 1970s. We first construct a simple model linking the average duration of unemployment with the speed of technical change. Using aggregate time-series data for the U.S., we find strong evidence that both the rate of TFP growth and investment in office, computing, and accounting equipment (OCA) per employee have a significant positive effect on mean unemployment duration. Moreover, literally all of the two-thirds rise in mean unemployment duration between 1971 and 1994 (two similar points in the business cycle) can be attributed to increases in OCA investment.
