The Role of Technological Change in Income Inequality in the United States

Abstract

This paper examines the impact of the technological change on income inequality in the United States of America. This is done by integrating theoretical and analytical findings of the channels through which technological change affects income inequality. The research is based on century-long income inequality data sets, although it prioritises the study of income inequality between the 1970s and the 2010s. The two major causes of rising income inequality have been technological change and globalisation. The paper also accounts for the other inequality triggers that have resulted from the political and economic structure of the country. The spread of automatisation and computerisation and of other changes associated with The Fourth Industrial Revolution are likely to reinforce skill-biased technological change. Therefore, new measures addressing income inequality, such as Universal Basic Income, are discussed.
