Hortaçsu's work is focused on empirically assessing the efficiency of markets. He utilizes detailed micro-level data from the markets studied to estimate preference and technology parameters that rationalize individual behavior.

This comparison also motivates discussions of how market rules can be altered to improve efficiency. He has applied the above framework...
