How does Katz use data in his research?
My approach relies heavily on detailed empirical analysis of large datasets, often drawn from government sources like the U.S. Census and Current Population Survey. I meticulously examine changes in wages, employment, and educational attainment over long periods. This allows me to identify significant trends, like the widening wage gap since the 1980s, and then to systematically test hypotheses about their underlying causes, be it technology, trade, or institutional factors.
