Computers and Wages. Wage gaps between more- and less-educated individuals have increased in the U.S. in recent decades. Some argue this is because computers have made skilled workers more productive. To find out if this is the case, you obtain data on computer use and the change in log wage gaps between high school and college educated workers in 230 U.S. labor markets in the 1990s. The variables are: = d_relwg90s growth in the gap in the natural log of wages between high school and college educated workers over the 1990s in each city; pcemp_m_c90s = #of PCs adopted per worker at the average business in each city. The following STATA output might be useful: summ d relwg 90s pcemp_m_c90s Variable | Obs Mean Std. Dev. Min Max d_relwg90s | 230 pcemp_m_c90s | 230 .1019509 .4579121 0480809 .0710858 -.046447 .2629593 .2495289 6682436 . correlate d_relwg 90s pcemp_m_c90s, cov (obs=230) | d_re~90s pce~90s. d_relwg90s | .002312 pcemp_m_c90s | .000379 .005053 a. Provide least squares estimates of the slope and intercept of a regression of d_relwg90s on pcemp_m_c90s.
