    Canaries in the Treasury Coal Mine with Bill Dudley & Jonathan Payne | Markus Academy | 167-2

This is part 2. Dudley is a Senior Advisor to Princeton’s Griswold Center and a former President of the Federal Reserve Bank of New York. Payne is an Assistant Professor at Princeton. A summary in three bullets: ● The expectations hypothesis holds in general throughout US history except in the period of 1965-1990, so that the risk premium on government debt was time-varying only then. ● The fact that Microsoft’s yields have widened with respect to other AAA corporates or sovereigns suggests growing default risks around AI, not that the government may be crowding out AI investment ● R* has drifted up, from zero after the financial crisis to 1.2% today (as projected by the Fed) Timestamps: [0:00] R* has moved up, and we only learn it through its works [8:15] The expectations hypothesis and the stock-bond correlation [23:12] Is the government crowding out AI investment? [27:25] Hope is not a strategy The views expressed by Jonathan's coauthors in the papers discussed are those of the authors and do not necessarily reflect the views of the Board of Governors of the Federal Reserve System.

    The Government Funding Advantage is No Free Lunch with Bill Dudley & Jonathan Payne | Ep. 167-1

This part covered the history of American debt starting in minute 21:09. Before then it started with a refresher on basic concepts to study yield curves. Dudley is a Senior Advisor to Princeton’s Griswold Center and a former President of the Federal Reserve Bank of New York. Payne is an Assistant Professor at Princeton. A summary in three bullets: ● There is no Phillips-style curve between debt-to-GDP ratios (safe asset scarcity) and the government funding advantage. The simple relationship disappears when adjusting our prior measures of the funding advantage for the tax treatment of the government’s long-term debt during the Great Inflation ● The US government’s funding advantage was largest in the 19th century during the national banking era, not after WWII or Bretton Woods. ● Governments face financing trilemma, having to pick two among: (1) a large funding advantage, (2) a solvent banking sector, (3) a regime that inflates the debt away. The funding advantage is a reward for prudence Timestamps: [00:00] Today’s yields are not high by historical standards [11:52] Fiscal-monetary interactions [22:38] The history of America’s debt [34:30] The national banking era was a stablecoin regime [41:15] The funding advantage is a reward for prudence The views expressed by Jonathan's coauthors in the papers discussed are those of the authors and do not necessarily reflect the views of the Board of Governors of the Federal Reserve System.

    A Mini-Series on AI for Economic Theorists & Mathematicians, Part 4: Promtps and Agent Swarms | Markus' Academy | Ep. 166-4

    Follow the link for the full summary: https://markusacademy.substack.com/p/ai-for-economic-theorists-and-mathematicians Link to sign up for the webinar series: https://markusacademy.substack.com/ Pietro Ortoleva and Fedor Sandomirskiy joined Markus' Academy for a mini-series on AI for economic theorists and mathematicians. This is episode 4. Both are economic theorists at Princeton University.The value has shifted from prompt engineering to context engineering: specify the task. Write a lazy two-line prompt, ask the same model that will do the work to expand it. Never let one session grade its own work, but run a separate verifier and, if the two disagree, a third instance as a judge. Fedor dissected the prompt OpenAI published for the cycle double cover proof - 64 agents, running at least eight hours, a supervisor eliminating agents that converge on the same route. And in his work adds tricks of his own.Timestamps:[0:00] Is prompt engineering still a thing?[3:40] Prompt expansion: let the model write the prompt[9:45] Prover versus verifier, LaTeX not PDF, and when to restart[16:43] Agent swarms, and AI proofreading

    A Mini-Series on AI for Economic Theorists & Mathematicians, Part 3: Which Model to Use | Markus' Academy | Ep. 166-3

    Follow the link for the full summary: https://markusacademy.substack.com/p/ai-for-economic-theorists-and-mathematicians Link to sign up for the webinar series: https://markusacademy.substack.com/ Pietro Ortoleva and Fedor Sandomirskiy joined Markus' Academy for a mini-series on AI for economic theorists and mathematicians. This is episode 3. Both are economic theorists at Princeton University.An AI's intelligence and stamina are substitutes. A slightly shallower model that grinds all day often gets further than a deeper one you can only afford to run for twenty minutes. Pietro compared the models available today: their preference, narrowly, is GPT-5.6, since it has more stamina than Fable. Pietro also argues that agents are fundamental in empirical work, but that for theory the browser is still enough for brainstorming.Timestamps:[0:00] The frontier since June: Fable 5, GPT-5.6, Opus 5[4:13] Intelligence and stamina are substitutes[8:53] The verdict, and what to run on a Pro, $20, or free budget[11:10] Browser or agents?

    A Mini-Series on AI for Economic Theorists & Mathematicians, Part 2: Can AI Be Creative? | Markus' Academy | Ep. 166-2

    Follow the link for the full summary: https://markusacademy.substack.com/p/ai-for-economic-theorists-and-mathematicians Link to sign up for the webinar series: https://markusacademy.substack.com/ Pietro Ortoleva and Fedor Sandomirskiy joined Markus' Academy for a mini-series on AI for economic theorists and mathematicians. This is episode 2. Both are economic theorists at Princeton University.In this video, Fedor asks whether models can actually generate new ideas. In economic theory this is hard to settle because a model's quality is subjective, while in math a proof either holds or it does not. AI is poor at attribution, but superb at aggregation of knowledge.Timestamps:[0:00] Can models be creative, and why the evidence comes from math[2:20] The ten Erdős problems episode, and Terence Tao's ledger[5:19] The unit distance conjecture falls[8:44] Jacobian, cycle double cover, and what it means for theory

    A Mini-Series on AI for Economic Theorists & Mathematicians, Part 1: Core Uses of AI for Economic Theory | Markus' Academy | Ep. 166-1

    Follow the link for the full summary: https://markusacademy.substack.com/p/ai-for-economic-theorists-and-mathematicians Link to sign up for the webinar series: https://markusacademy.substack.com/ Pietro Ortoleva and Fedor Sandomirskiy joined Markus' Academy for a mini-series on AI for economic theorists and mathematicians. This is episode 1. Both are economic theorists at Princeton University.In this first video, Pietro sets out where AI fits into theory research. Unlike mathematics, a theory paper does not set out to prove a stated conjecture; it searches for a fixed point between defensible assumptions, interesting statements, and proofs that certify them. AI changes the cost of each loop of that search. Pietro lists seven use cases for AI in theory, and argues that sketching is the most underused of them. On proofs, frontier models can now generate reliable proofs of the kind of model economists typically write. The higher-value uses are attack (a hostile referee hunting for weak steps), repair (which assumption rescues a false statement) and inspiration: even a wrong proof can point to the right route.Timestamps:[0:00] Introduction, and economic theory as a fixed point[5:12] Seven use cases, and why sketching is the most underused[8:46] Proofs: attack, repair, and inspiration[15:12] Extensions, microfoundations, simplifications
