What unites the essays in this thesis is their focus on studying the aggregate effects of individual firm decisions. Chapter 2 demonstrates that pressure from foreign competition can reduce managerial slack in domestic firms, and that this was a substantial source of productivity gains in Chile following the country's unilateral trade liberalization in the 1970s. Chapter 3 demonstrates theoretically how firms' choices of organizational structure lead to the high skill premium seen among large firms. Finally, in Chapter 4, I show that in an environment where firm market power differs across industries, firm technological upgrading decisions amplify market distortions and increase allocative inefficiency.en-USDevelopmentTradeThesis or Dissertation
