How has this reshaped racial and ethnic earnings disparities? I answer this question with American demographic and establishment microdata from the 1970s to the present. I find that black and Hispanic workers have become increasingly siloed into low-revenue, low-paying firms. About half of this trend has been driven by the relocation of blue-collar occupations to low-paying firms, reflecting the rise of outsourcing and related transformations. Today, this pattern of workplace marginalization contributes about 15% and 25%, respectively, to the black-white and Hispanic-white pay gaps. ### Fiona Chen #### PhD Candidate in Business Economics and Stone PhD Scholar in Inequality and Wealth Concentration ##### "Generative AI and Inequality" **Abstract:** How do generative AI technologies affect productivity, organizational structure, and inequality? We study the effects of tech firms' adoption of GitHub Copilot, a generative AI software development tool. To do so, we leverage a novel proprietary dataset from a worker management platform on 80,000 workers from 400 firms. We begin by documenting Copilot’s effects on engineers’ productivity. Then, we provide evidence on shifts in task allocation and labor demand. Finally, we examine the differential impacts of this technology of workers from different backgrounds.
