In my dissertation, I study how organizational and regulatory changes in the U.S. market for corporate control, where thousands of large companies are bought and sold each year, are affecting workers.  I use restricted Census data linking 70 million workers and their employers over time, bolstered with firm and worker surveys and censuses.  This work develops the sociology of markets by explaining how private equity and strategic acquisitions spill over to affect the social mobility of executives, managers, and technical and other workers.
