In my dissertation, I study how changes in the U.S. market for corporate control, where thousands of large companies are acquired each year, are affecting worker earnings and mobility.  I use restricted Census data linking 100+ million U.S. employees and their employers over time, bolstered with company financial information and worker surveys.  This develops the sociology of markets by explaining how private equity and strategic acquisitions spill over to affect the employment and earnings of higher- versus lower-positioned workers.
