This document discusses trends in labor markets and the relationship between wages, employment, and unemployment. It covers five key trends: 1) real wage growth in industrialized countries in the 20th century, 2) stagnating real wage growth since 1973, 3) increased wage inequality in the US, 4) growing employment numbers, and 5) higher unemployment in Western Europe compared to the US. It uses supply and demand analysis to explain how changes in labor supply and demand impact wages and employment. Different types of unemployment like frictional, cyclical, and structural unemployment are also defined.
