- 요약Markets are increasingly mediated by digital platforms. This dissertation studies the design of platforms with the goal of improving market efficiency through appropriate prices on externalities users impose on one another. This echoes the lessons from the field of market design, which has shown that even with a fixed set of market participants, the design of a market can have a significant impact on outcomes. At the same time, this dissertation takes seriously the distorted incentives of platforms as profit-seeking entities rather than benevolent social planners, following the long literature on competition between two-sided platforms.In the first chapter, I study pricing equilibria among micro mobility platforms in Washington D.C., which offer electric scooters with flexible drop off locations. Current pricing schemes use simple two-part tariffs based on distance or time, ignoring the externality of users' destination choices on the supply distribution, and pricing fails to account for varying demand across origins. Full origin-destination pricing faces both regulatory barriers (due to equity concerns) and implementation challenges. To address these issues, I develop a reinforcement learning algorithm to compute flexible profit-maximizing prices and estimate a demand model for Washington D.C. to evaluate distributional impacts of flexible pricing. My analysis reveals that while peripheral neighborhoods experience modest negative effects, these are outweighed by substantial welfare gains in the city core, with no clear correlation to neighborhood income levels.The next two chapters both focus on the US trucking market, using data from a digital broker's auction platform. In the second chapter, I focus on temporal frictions in the dynamic shipment allocation process: as carriers search for shipments sequentially, they may exit the market before seeing their ideal shipment. As a remedy, the platform's generous cancellation policy allows carriers to tentatively match with a shipment while continuing to search for better opportunities. To evaluate the efficient price of cancellations, I estimate a structural model of the market and simulate the effects of different cancellation policies on market outcomes. I find that low penalties for reneging are both welfare- and profit-maximizing, so long as the penalties are imposed through a non-pecuniary reputational mechanism that does not generate any direct revenues. If pecuniary penalties can feasibly be collected with minimal transaction costs, I find that the platform can extract more surplus from the market by marking up the fee for the right to renege.The third chapter shifts attention to the spatial dimension of the trucking market. Using data from the same digital brokerage platform, we first develop a more stylized auction model that abstracts away the temporal dimension, allowing us to invert bids into costs on a large scale. Using the inverted costs, we estimate a flexible carrier cost function to separate fixed costs, per-mile costs, home preferences, and continuation values. We then develop a spatial equilibrium model allowing us to simulate various policy interventions in the freight market. Our richly micro-founded model enables us to evaluate both conventional supply-side interventions like entry subsidies and changes to the design of the broker's auction platform.
