Research Statement

The growth of the Internet and other digitization technologies has enabled the unbundling of the physical and information components of the value chain and has led to an explosion of information made available to online consumers. In addition, digitization has transformed the dynamics of many traditional settings including retail, media and advertising, leaving firms to compete in markets with new rules and players. The fundamental changes brought about by digitization call for a systematic analysis of their impacts. Understanding the implications of this new informational landscape for theory and practice is one of the key objectives of my research. Online technologies have equipped firms with tools that allow them to move closer to offering targeted information. A key resource that aids in this strategy is the online search conducted by users. One stream of my research seeks to understand how firms can use their knowledge of online consumer search and information seeking behaviors to design optimal information provision strategies in online markets. A second stream examines the economic outcomes in paid search auctions or sponsored search advertising contexts. I am interested in learning about how firms make bidding and advertising decisions, and ways in which they can improve their strategies by better understanding how consumers search in these markets. A third and most recent stream examines the emergent crowd-based platforms for capital and labor, namely crowdfunding and crowdsourcing. I am very interested in examining the economic and social factors that are at play on crowdfunding platforms such as Kickstarter and Sellaband. My work attempts to model how peer influence and observational learning affect participant decisions when they fund multiple projects across time. Another related study examines participant dynamics in crowdsourced design contests, and ways in which platforms can improve both the quality and efficiency of submissions, and post-contest earnings.
