Decomposing the Education Wage Gap: Everything but the Kitchen Sink

by Julie L. Hotchkiss and Menbere Shiferaw

The authors use a multitude of data sources to provide a comprehensive, multidimensional decomposition of wages across both time and educational status. Their results confirm the importance of investments in and use of technology, which has been the focus of most of the previous literature. The authors also show that demand and supply factors played very different roles in the growing wage gaps of the 1980s and 1990s.
