Behind the Headlines: Understanding Caroline Ellison's Accomplished Economist Parents

The high-profile sentencing of Caroline Ellison, former CEO of Alameda Research, has drawn significant public attention not only to her involvement in the FTX-Alameda fraud scandal but also to her family background. When Ellison received her two-year federal prison sentence on September 24, 2024, her parents—Glenn and Sara Fisher Ellison—were present in the courtroom, observing the proceedings alongside her two younger sisters. This moment highlighted a striking contrast: while Ellison faced serious legal consequences for her role in the collapse that brought down Sam Bankman-Fried, her parents represent a world of academic achievement and integrity at one of America’s most prestigious institutions.

The Ellison Family at MIT’s Economics Department

Both of Caroline Ellison’s parents hold distinguished positions within MIT’s Department of Economics. Glenn Ellison serves as a full professor, having previously completed two terms leading the entire department. His academic work spans multiple disciplines, with research interests encompassing game theory, industrial organization, education, and finance. Beyond his theoretical contributions, Ellison has authored the “Hard Math” educational textbook series for younger students and published extensively on topics ranging from technological market dynamics to the gender gap in mathematics education.

Sara Fisher Ellison maintains the role of senior lecturer within the same department. Her scholarly focus gravitates toward practical economic applications, particularly examining e-commerce platforms and pharmaceutical industry structures. Through her work, she has analyzed how internet technologies reshape market competition, pricing mechanisms, and supply-demand relationships across various sectors.

Glenn and Sara Ellison’s Diverse Research Portfolios

The two economists’ individual research trajectories demonstrate complementary approaches to modern economic challenges. While Glenn’s work leans toward theoretical frameworks and educational innovation, Sara’s research addresses real-world market phenomena. Glenn’s publications touch on tax policy, technology adoption, and niche academic interests, whereas Sara investigates how digital transformation affects consumer pricing and competition in specific industries.

Academic Collaboration and Shared Scholarly Interests

Throughout their careers at MIT, the Ellisons have frequently joined forces on joint research projects. In 2005, they jointly published “Lessons About Markets From the Internet,” followed by “Search and Obfuscation in a Technologically Changing Retail Environment” in 2018. Their most recent collaborative project examined home-sharing platforms like Airbnb, exploring how such services might simultaneously enhance social welfare through more intensive property utilization while potentially creating challenges for primary housing availability. This research reflects their shared commitment to understanding how technological disruption reshapes economic systems and consumer welfare.

The Sentencing and Family Support

Judge Lewis Kaplan’s decision to impose a two-year prison sentence proved harsher than many had anticipated. Although Ellison’s legal representatives had sought no incarceration, and prosecutors had advocated for a reduced sentence given her substantial cooperation in the case against Bankman-Fried, federal sentencing guidelines in New York require her to serve at least two-thirds of her term. One concession granted by the judge was permission for Ellison to serve her sentence at a facility near Boston, allowing proximity to her family. As of March 2026, she has become eligible for parole consideration, marking a significant milestone for the Ellison family members who continue to maintain their positions and reputation at MIT’s esteemed economics faculty.
