Empirical work has been limited in its ability to directly study whether skill requirements in the workplace have been rising and whether these changes have been related to technological change. This article answers these questions using a unique data set from West Germany that enabled me to look at how skill requirements have changed within occupations. I show that occupations require more complex skills today than in 1979 and that the changes in skill requirements have been most pronounced in rapidly computerizing occupations. Changes in occupational content account for about 36% of the recent educational upgrading in employment.

Abstract After the fall of the Berlin Wall on November 9, 1989, and the collapse of the German Democratic Republic, a sudden, unexpected, and massive influx of East German migrants hit the entire West German labor market. The context is well suited for investigating whether immigration influences natives' wages and how the effects depend on product and labor market conditions. We propose direct measures of potential migration with exogenous variation, compare migrants to natives with similar capabilities, and segment the labor market along predetermined margins. We find that immigration can have negative effects on the wages of natives. These effects surface when product and labor markets are competitive but not under regulations that restrict the entry of firms and provide workers with a strong influence on firms' decision making.

In this study, we explore a new approach for analyzing changes in the gender pay gap that uses direct measures of job tasks and gives a comprehensive characterization of how work for men and women has changed in recent decades. Using data from West Germany, we find that women have witnessed relative increases in nonroutine analytic and interactive tasks. The most notable difference between the genders is, however, the pronounced relative decline in routine task inputs among women, driven, at least in part, by technological change. These changes explain a substantial fraction of the closing of the gender wage gap.
