Essays on applied mircoeconomics and finance

This dissertation consists of four chapters. Chapter 1 studies the effect of online review manipulations on review systems. Chapter 2 and Chapter 3 are co-authored with Ali Kakhbod and focus on post-trade transparency in dynamic over-the-counter markets. Chapter 4 is co-authored with Umut Dur, Parag A. Pathak and Tayfun Sönmez and studies the effect of the Taiwan mechanism, a mechanism that allocates high school seats to applicants. Chapter 1 shows that the conventional impression holds in the short-run that review manipulation makes review systems less informative. In the long-run, however., a manipulated review system can contain the same level of information as an un-manipulated counterpart. I develop a dynamic programming model with fixed product quality and naive buyers who are unaware of manipulation. I then extend it to consider endogenous product quality and sophisticated buyers. I also identify an unexpected effect of a policy to target sellers and check for manipulation.
