how (a) the computing revolution, (b) international trade, and (c) immigration have contributed to rising income inequality in the US. For example, the import of goods made by low-skill workers abroad has depressed the prices of these goods in the US, causing low-skill workers in the US to become less attractive to firms (a worker is attractive to employers insofar as she can produce goods that will make her employer a large profit). The demand for low-skill workers in the US has, thus, decreased , causing their equilibrium wage to decrease. The wage gap between low-skill and high-skill workers has, as a result, widened, contributing to a rise in income inequality.
