In Part I of this dissertation I study executive compensation contracts that reward managers based on revenue in addition to profit. I find that the cost of incentive provision is higher under revenue-oriented contracts. Such contracts could be a profit-enhancing tool for shareholders in oligopolistic markets, a phenomenon known as strategic delegation. I analyze the interplay between strategic delegation and incentive provision. Results depend non-trivially on the model of competition and whether the manager cuts costs or increases demand. In Part II I study how review systems affect the behavior of customers and firms in a large marketplace called Steam. Chapter 2 compares two approaches to estimating the effect of reviews on sales: a panel regression and a regression discontinuity design. I find that having better reviews increases sales by 3-7%. I uncover an identification issue with the regression discontinuity design based on the review score of a product and propose an alternative design. In Chapter 3 I document that firms in online marketplaces use price promotions to facilitate transitions to better review tiers (similar to the number of stars on Amazon.com). I find that firms close to upgrading their tier are 4-9% more likely to discount. Two effects are at play. First, a selection effect arises because customers who buy during a discount could be different from the regular ones. Second, a variance effect reflects the idea that positive reviews could help the firm move up a review tier, while negative reviews would keep the tier unchanged. I estimate a tractable structural model of demand and reviewing behavior, and find evidence of the importance of the variance effect.
