Is inequality an inevitable by-product of skill-biased technical change?

This article examines trends in relative wages between high- and medium-skilled workers and between medium- and low-skilled workers in Finland, Germany, Italy, South Korea and the US over the period 1970-2005. It is found that there are large differences in the evolution wage inequality across the countries in our sample, with some countries showing a long-run upward trend in relative wages (such as the US, Germany and Italy) and others showing a long-run downward trend (such as Finland and Korea). The main conclusion from our results is that inequality is not an inevitable by-product of technological change.
