Keystone Applies Data Shapley Model in Prediction of Credit Defaults

SEATTLE, WA – Keystone, an innovative economics, technology, and strategy consulting firm, presented their latest research on data valuations in credit default predictions leveraging a Data Shapley application at the fifth annual National Association of Business Economists - Tech Economics Conference (NABE TEC2021). The Keystone team of authors included Junsu Choi (an Engagement Manager at the firm), and Jill Furzer, PhD, and Vitoria Rabello De Castro, both economists at Keystone. The conference is one of the marquee events for economists across sectors, bringing together hundreds of economists, data scientists, and business leaders and this year, the event's theme centered around “Economics in the Age of Algorithms, Experiments, and A.I.” Attendees joined the virtual TEC2021 conference to discuss and learn from experts how artificial intelligence (AI), behavioral economics, and other tools are impacting businesses. Keystone Expert and the Economics of Technology Professor at Stanford, Susan Athey, spoke on the topic of economists in the tech sector and joined other leading economists and academics in the space, including Pat Bajari (VP Core AI and Chief Economist, Amazon), David Card (Nobel Laureate; Class of 1950 Professor of Economics, UC Berkeley), Hal Varian (Chief Economist, Google). Other session topics included the future of remote work, market design and behavior, as well as the evolving landscape of competition policy. Keystone's own economists Jill Furzer and Vitoria Rabello De Castro presented their research assessing the value of data for a bank's decision of who to lend to. Their application of a Data Shapley method shows how this data valuation technique can inform firm data acquisition and discarding decisions. The empirical results also reveal a tradeoff between short run costs associated with lending to individuals who are more likely to default and long-term savings from algorithmic learning from underrepresented data points. “This research brings Keystone's economic expertise and technical knowledge about machine learning methodologies to solve of challenging problems affecting businesses,” notes Vitoria Rabello De Castro.
