Choi’s research interests are in real effects of accounting, earnings quality, aggregate earnings, voluntary disclosure, and macroeconomics.
Choi’s current project studies the impact of accounting fraud on labor markets. Anecdotal evidence suggests that former employees of Enron suffered financially after the Enron accounting scandal broke. The question this project addresses is whether their labor market outcomes could have been different if Enron had not engaged in accounting fraud. Using the U.S. Census Bureau’s matched employer-employee panel dataset, this project investigates how accounting fraud influences labor markets.
Brandon Gipper completed his PhD at the University of Chicago Booth School of Business in 2016. He earned a BS in economics and mathematics and a master’s in accounting from the University of Michigan Ross School of Business.
Gipper’s primary research focuses on empirical accounting topics, including the effects of disclosure on corporate governance, regulatory interaction in the audit industry, and accounting standard setting, as well as economic questions related to auditing, the firm’s information environment, and capital formation.
John Kepler joined Stanford Graduate School of Business as an assistant professor of accounting in July 2019. He studies the interrelated nature that firms’ explicit and implicit contracts play in shaping firms’ financial reporting and corporate governance practices. His recent work has examined the role of executive bonus plans in facilitating cooperation among management team members. Other work examines how corporate insiders exploit their private information advantage about corporate audit findings for personal gain.
Kepler received his PhD in accounting from the the Wharton School of the University of Pennsylvania and a BA in accounting and finance from the Foster School of Business of the University of Washington. Prior to his studies at Wharton, he worked in financial planning and analysis for Nordstrom in Seattle, Washington.
Kepler’s research relates to documenting and understanding the interrelated nature that firms’ contracts — both explicit and implicit — play in driving firms’ financial reporting and corporate governance practices.
Charles M. C. Lee is the Moghadam Family Professor of Management and professor of accounting at Stanford Graduate School of Business.
Lee received his BMath from the University of Waterloo in 1981, and his MBA in 1989 and PhD in 1990 from Cornell University. He has been a faculty member at the Michigan Business School from 1990 to 1995 and the Johnson Graduate School of Management, Cornell University from 1996 to 2004. From 1995 to 1996, he was visiting economist at the New York Stock Exchange. At Cornell, he held the Henrietta Johnson Louis Professorship in Management and was director of the Parker Center for Investment Research.
From 2004 to July 2008, Lee was managing firector at Barclays Global Investors (BGI; now Blackrock). He joined Stanford GSB as visiting professor in July 2008 while continuing to serve as an exclusive senior consultant to BGI, and became a full-time faculty member in July 2009.
Broadly speaking, Dr. Lee is interested in the effect of human cognitive constraints on market participants and other factors that impact the efficiency with which market prices incorporate information. His publications have been in the areas of behavioral finance, equity valuation, financial analysis, quantitative investing, market microstructure, and security market regulation.
Rebecca Lester joined Stanford Graduate School of Business as an assistant professor of accounting in July 2015. She studies the effects of accounting rules and tax policies on domestic and multinational firm investment and employment decisions. She received her PhD in Accounting from the MIT Sloan School of Management and both a BA and Masters of Accountancy from the University of Tennessee. Prior to her studies at MIT, she was a Manager in the M&A Transaction Services practice of Deloitte in Chicago, Illinois.
Lester’s research focuses on the economic consequences of U.S. tax policies on multinational companies. Specifically, her work studies how accounting rules and tax policies affect firm investment and employment decisions. A recent project looked at the effect of the firm’s information environment on the choice between foreign outsourcing and integration.
Projects in Economics
Susan Athey’s research is in the areas of industrial organization, microeconomic theory, and applied econometrics. Her current research focuses on the design of auction-based marketplaces and the economics of the internet, primarily on online advertising and the economics of the news media.
Athey’s project uses data from internet browsing to show that abnormal volumes of ticker lookups at major finance sites is predictive of abnormal asset returns. Prior studies of this phenomena used Google Trends data, which does not incorporate lookups at major finance sites and is too aggregate and noisy to provide precise identification of the effects of lookups, especially for medium and low-volume stocks. Her project examines the impact of lookups on returns over time and further studies the relationship between other types of browsing activities, such as visiting trading websites and financial news websites, and ticker lookups, in order to understand what drives ticker lookups, as well as to disentangle which types of traders seem to have the greatest impact on stock prices. She is also looking at asymmetries between lookups associated with declining or increasing stock prices to further understand the scenarios in which individual investor behavior impact price.
Rebecca Diamond is an associate professor of economics at Stanford Graduate School of Business where she teaches Data and Decisions. Her current research studies the causes and consequence of segregation of households by income and education level across neighborhoods and labor markets. She was a postdoctoral fellow at the Stanford Institute for Economic Policy Research from 2013 to 2014. She received her PhD in economics from Harvard University in 2013 and her BS in physics, economics, and mathematics from Yale University in 2007.
Diamond is an applied micro economist studying local labor and housing markets. Her recent research focuses on the causes and consequences of diverging economic growth across U.S. cities and its effects on inequality. A recent project analyzes why U.S. households have become increasingly geographically segregated by education level and how this segregation led to increased economic well-being inequality. Her work uses large datasets related to local labor and real-estate markets and a combination of structural and reduced-form estimation techniques.
Guido Imbens is The Applied Econometrics Professor and professor of economics at Stanford Graduate School of Business. After graduating from Brown University Guido taught at Harvard University, UCLA, and UC Berkeley. He joined Stanford GSB in 2012.
Imbens does research in econometrics and statistics. His research focuses on developing methods for drawing casual inferences in experimental and observational studies, including matching, instrumental variables, synthetic control, and regression discontinuity designs. Recent projects include the use of generative adversarial networks to guide Monte Carlo studies.
Paulo Somaini studies industrial organization, econometrics and microeconomic theory. His work shows how the behavior of agents in strategic environments can reveal their preferences and information. In “Competition and Interdependent Costs in Michigan Highway Procurement Auctions” he finds that contrary to naïve theoretical predictions, firms in Michigan did not bid more aggressively for projects closer to their competitors’ plants. He shows that firms’ response to competitive pressure reveals the extent and magnitude of the winner’s curse in this type of auctions.
Somaini’s most recent work analyses the assignment mechanism used to assign Kindergarten students to schools in Cambridge, MA. This work shows that while parents have strong incentives to misreport their preferences to the school district, their reports provide valuable information about how much they like each school which is useful to simulate their welfare under alternative assignment rules.
Takuo Sugaya is an associate professor of economics at Stanford Graduate School of Business, where he teaches Managerial Economics. His current research focuses on dynamic games — repeated games, stochastic games, and dynamic Bayesian games — and the environments in which different sides will engage in cooperative long-run relationships. Takuo received his PhD in economics from Princeton University in 2012 and his MA in economics and BA in international relations from University of Tokyo.
Sugaya’s research is in the area of microeconomic theory. His work in game theory examines how entities with their own objectives and information can sustain cooperation in the long term. In a recent paper, he proposes a self-enforcing mechanism that incentivizes firms to maintain collaborative relationships although they are uncertain about the information and strategic behavior of the other parties.
Ali Yurukoglu is an associate professor at Stanford Graduate School of Business, where he teaches Data and Decisions in the first year of the MBA program. He received a BA in economics and mathematics from Northwestern University, and a PhD in economics from New York University’s Stern School of Business.
Yurukoglu’s research is in the area of industrial organization. Recently, he used the tools of game theory and statistics to study pricing regulation in the cable and satellite television industry, and the effect of mergers between firms at different points on the supply chain.

Hanno Lustig has worked at the intersection of macroeconomics and finance. Recently, his research has focused on understanding the forces that determine exchange rates in currency markets. His research has shown how currencies have different risk characteristics that are determined by a country’s role in the global economy. These risk characteristics help to understand the behavior of exchange rates. In addition, Lustig has explored the impact of government guarantees on the pricing of tail risk borne by large financial institutions. More recently, Lustig has also worked on understanding the determinants of a firm’s volatility (volatility of sales, cash flows, stock returns etc).
Matteo Maggiori is an associate professor of finance at Stanford Graduate School of Business. His research focuses on international macroeconomics and finance. His research topics have included the analysis of exchange rate dynamics, global capital flows, the international financial system, the role of the dollar as a reserve currency, tax havens, bubbles, expectations and portfolio investment, and very long-run discount rates.

A particular area of interest is the application of Bayesian econometric methods to problems in marketing and empirical industrial organization.
Projects in Operations, Information & Technology
Jann Spiess holds a PhD in economics from Harvard University. Previously, Jann obtained a master’s degree in public policy from the Harvard Kennedy School. His background is in mathematics with a focus on probability theory and combinatorics, which he studied at the University of Cambridge (Part III of the Mathematical Tripos) and the Technical University of Munich. Jann also studied and worked in Hangzhou, China and Ouagadougou, Burkina Faso.
Jann works on integrating techniques and insights from machine learning into the econometric toolbox. His research brings together microeconometric methods, statistical decision theory, and mechanism design to clarify the use of flexible prediction algorithms in causal inference and data-driven decision-making. He is particularly interested in the role of human and machine decisions in replicable and robust inferences from big data.
Projects in Organizational Behavior
Julien Clement studies organization design and its impact on collaboration within and across organizations. He is generally interested in understanding the link between formal organizational structure and informal social relationships: how does an organization’s structure affect how its members form relationships and develop routines? How can it help them adapt these routines when environmental demands change? And when can organizations thrive without any formal structure?
Julien investigates these issues through a ‘micro-analytic’ approach: rather than study organizations as broad aggregates, he starts by observing social interactions among individuals and tries to understand how organizational structure enables these interactions to aggregate into organizational outcomes. His work has relied on a variety of analytical methods (network analysis, agent-based models, big-data analytics) applied in a variety of contexts including the television game-show industry, professional videogaming (e-Sports) and mobile healthcare in Africa. Most recently, Julien started studying how the deployment of artificial intelligence inside organizations may affect collaboration and learning among their members.
Aruna Ranganathan studies questions of work and employment in the context of economic development. By applying novel methods that combine field-experimental and quantitative research designs with ethnography and interviews, her research investigates how low-income occupations in developing countries are governed, organized, seek meaning through their work and navigate the market. Through her research, Ranganathan strives to advance our theoretical understanding of work, while informing the design of labor-market institutions and policy for the developing world.
Over the last year, Ranganathan has been working with a large garment manufacturer in southern India and is investigating the impact of several internal organizational practices in the garment factories on worker outcomes. In particular, she is working with a research fellow to look at the impact of employer-sponsored childcare on working mothers’ labor force participation and is further investigating how this effect varies based on the gender composition of the working mothers’ children.
Projects in Political Economics
Katherine Casey is an associate professor of political economy at Stanford Graduate School of Business. She teaches a Strategy Beyond Markets course for first year MBAs that is tailored to the particular opportunities and challenges facing firms investing in developing economies. Her current research examines how asymmetric information in electoral contests affects voting choice and public sector performance, and the impact of foreign aid on collective action and economic development. Katherine holds a PhD in economics from Brown University and a master’s in public policy from Harvard University. She has worked as a consultant for the World Bank in Madagascar, the Comoros, and Indonesia, and has spent several years working with the government of Sierra Leone. Her research explores political economy issues in developing countries. Her approach combines applied theory, original data collection, and randomized trials.
One of Casey’s current research projects looks at the long run impacts of institution building. Her current project is a long run follow-up to an experimental evaluation of a community driven development program in Sierra Leone.
