These are tools I've built for my courses and students since 2023.
Virtual Econ (2023): Game-based economics assessments with randomness embedded in the outcomes, so there is no single answer to copy. Scored on whether a student's reasoning moves in the right direction, not whether they hit a number.
Principles of Macroeconomics (2024 – 2026): A full course site with AI-adjacent activities designed for classes where every student has a frontier model available.
Sifter Finance (2026): Institutional-grade financial tools for student-managed investment funds, with a credentialing layer that measures calibration against reality rather than performance for a grader. Available to individual students and investment funds.
Stanford IFDM Resource Hub (2026): The financial-education toolkit I built and operate for Stanford GSB's Initiative for Financial Decision-Making.
I also wrote Introduction to Macroeconomics (available at Tophat): An interactive macroeconomics textbook used in my large-enrollment courses.
