Abstract
The emergence of social networks has enabled e-commerce at the local scale, facilitated by sites such as Craigslist and Facebook Marketplace, allowing individuals to discover and exchange goods with each other directly. Sellers can use social networks to match items with buyers in diverse or saturated markets. This thesis investigates auctions with graphical structure, in which bidders can both submit bids for the item and refer other bidders to participate in the auction. This thesis has two main contributions. First, the average revenue is derived across distinct graph structures for an existing auction format under assumptions on bidder valuation distributions and strategic behavior. Second, a new auction format is proposed for multi-item auctions and is shown to outperform existing multi-item auctions in a specific simulation scenario.
