1/ Week 30: The theory paper(s) in focus this week are KMR 93 & Young 93, which provided a remarkably elegant evolutionary perspective to equilibrium selection in games. If games have multiple equilibria, which is more "reasonable", if at all? A deep problem in game theory.

1/ Week 28: Theory paper in focus this week is the seminal article by Anthony Atkinson and @josephestiglitz.bsky.social that is now famously referred to as the "zero commodity/ capital taxation" benchmark in public economics. It has led to much technical & policy debates. Let's find out.

1/ Week 27: This week two related theory papers in focus: simultaneous & seminal in helping us elegantly formalize herd behavior / information cascades & triggering a fascinating literature across subfields in economics. Banerjee 1992 and Bikhchandani, Hirshleifer & Welch 1992.

Week 9: The theory paper in focus this week is the seminal paper on the theory of the firm by Grossman and Hart published in the JPE in 1986. The voyage starts with a remarkable observation by Coase: Why does a firm exist or differently why is the entire economy not a firm?

Week 7: The theory paper in focus this week is "Kidney Exchange" by @alroth.bsky.social, @tayfunsonmez.bsky.social, @muunver.bsky.social. Undoubtedly, one of the most influential (in terms of research in econ) and impactful (in terms of goodness in society) papers of 21st century (micro)economics.

Week 6: The theory paper in focus this week is the iconic "Electronic mail game" by @arielrubinstein.bsky.social. It is characteristic Rubinstein---communicating a big idea with elegant simplicity. It brought into focus failures of common knowledge, by extension failures in coordination.

Week 5: With apologies for the hiatus, this week's theory paper in focus is a super creative take on how to design RCTs when unobserved effort of treatment group limits external validity. It is a beautiful exercise in putting principal-agent theory to the design of experiments.

Week 3: This week's theory paper in focus is Political Correctness (2001) by Stephen Morris. It is a masterpiece in what economists called applied theory--crafty story telling about interesting facts around us that uses elegant mathematical modeling. www.jstor.org/stable/10.10...

Week 2: This week's theory paper in focus is a brilliant conceptual puzzle piece by Thomas & Worrall (1990). What are the implications of risk sharing/insurance provision over time when income is private? They have a surprising answer: it necessarily leads to long-term impoverishment.

Week 1: This year, I'll (try my best to) summarize & bring to attention one cool economic theory paper a week (so hopefully 52 in total). First up is one of my all time favorites: Bargaining and Reputation by Dilip Abreu and Faruk Gul. It is theoretical elegance, personified.

Drawing the year to a close, hiked up Taktsang, the Tiger’s Nest. Padmasambhava, considered to be the pioneer of Tibetan Buddhism, and a revered figure in Bhutan, meditated and practiced from here in the 8th century. Happy New Year everyone. Be kind to yourself and others :)

With the rapid progress in AI, learning “how to learn” is going to be significantly more important than “what to learn”, for what to learn would be a moving target, moving at a pace much faster then recent human history.

Finals day. 400 students packed in an auditorium to take the exam you’ve written. Observing the anxiety from the other side still seems surreal. The calmness before putting ink to the storm of preparation inside. tinge of guilt perhaps that I could’ve prepared better.
