Market Equilibrium Models in Large-Scale Internet Markets

Innovative Technology at the Interface of Finance and Operations


Markets and their corresponding equilibrium concepts have traditionally been used as very powerful building blocks to find allocations and prices. This chapter provides examples of the use of Fisher markets in the technology industry. We focus on Internet advertising auctions, fair division problems, content recommendation systems, and robust abstractions of large-scale markets. After introducing these markets, we describe how these models fit the relevant application domains and what insights they can generate, exhibiting the most important theoretical and computational results from the recent literature on these topics.
