Is wage inequality driven by gaps between firms rather than within?
Core argument: Rising U.S. wage inequality from 1978 to 2012 was driven primarily by widening pay differences between firms rather than within them, with the gap between top executives and average employees inside firms increasing only slightly.
From 1978 to 2012, the increase in wage inequality in the U.S. has been primarily driven by disparities between companies rather than within them. The wage gap between top executives and average employees within firms has only increased slightly, challenging the notion that internal pay differences are the main cause of rising inequality. Instead, the divergence in average pay between companies like Apple and McDonald's illustrates this trend, as some firms significantly outpace others in compensation. This shift underscores the need to examine why certain companies excel financially while others lag, as this inter-company disparity is a key factor in understanding income inequality. Additionally, the male-female wage gap within companies has decreased, indicating progress in gender pay equity.
