Epistemological Econ Question: We have many frictionless benchmarks. I.e., Modigliani-Miller, Ricardian Equivalence, Real-Business Cycle, Arrow-Debreu, Wallace, Backus-Kehoe-Kydland, Atkison-Stiglitz, etc. How do you explain the value developing such benchmarks to students?

@SakiBigio When deriving those benchmark results, you discover the precise (often narrow) assumptions needed for them to hold — making you more aware of the limitations and setting the stage for subsequent work. Once aware of needed assumptions, you know where you can work to relax them

Important tips from #EconMeToo: (1) save text messages/emails that could be evidence of bad behavior; (2) tell a friend if/when something happens, even if you're not sure you'll ever want to tell anyone else; (3) save a report in @callisto once it expands to all .edu emails.

Revision rooky mistake story time:
I was lucky to get three positive reviewers who gave very constructive comments. One of the comments highlighted that it is confusing to use two samples of the data in different sections. I agreed, and then...

``Consumers are left-digit biased, buying as if $3.00 is 22 cent more expensive than $2.99. However, firms underestimate this bias and price heuristically, forgoing profits.''

Since 2000, as income has continued to rise, per capita holiday gift spending has actually fallen. While holiday gift spending remains normal in post-2000 cross-household comparisons, it appears inferior in the national time series. US holiday gift giving is in retreat.

Tyler Ransom@tyleransom
As I was grading my final exam for my upper-level undergraduate Economics of Education course, I decided to check how ChatGPT would do on the exam.
Answer: ChatGPT scored a 77%, which was just slightly below the class average.

ChatGPT is bad at economics. A few examples:
1⃣ It does not understand Ricardo's 1817's comparative advantage theory. Its view is stuck on Smith's 1776 absolute advantage theory.
