I'm really very different when I teach causal inference because I make us use spreadsheets to calculate individual treatment effects off of potential outcomes, make us write down treatment assignments based on a hypothesized treatment assignment mechanism, use the switching… …equation to select a potential outcome based on that treatment assignment, and then use all of that to emphasize the difference between a potential outcome and a realized outcome.

I think Goldin and Katz idea of skill biased tech change is the right paradigm to use when understanding ChatGPT as a disruptive force. We don’t have a good understanding of its longrun effects bc all studies are short run so far as it’s so new. But consider this. 1/ @erikbryn et al have a study looking at a staggered rollout of generative AI at a firm of customer service agents; workers had access iow to a ChatGPT bot to assist them with customer complaints. As with many studies I’ve seen, big increased productivity gains. 2/

We are now t-1 days away from the first Mixtape Sessions workshop of 2023 - my flagship intro to causal inference aptly named "Causal Inference 1". Here's the link:

I'm teaching a class this semester called "Issues in Economics" for undergrads, non-majors, from outside the business school. I had such an amazing experience teaching my history of econ thought class as a readings and discussion class, I decided to do it again. 1/ I googled "how many pages should I assign each week for college" and found that on average college students were reading between 30-40 pages a week in their classes. I wasn't sure if that was total pages, or per class. 2/

Just wanted to pop in and share abt some upcoming workshops at Mixtape Sessions. There's two coming in February that I wanted to first announce, then another one later. The first is my causal inference I workshops. You can see the description here:

mixtapesessions.io/session/ci_i_f… I'm currently rewriting the Mixtape. In my mind it's called "New Edition", and it's really taking a lot of willpower not to mine 1980s R&B boy band New Edition lyrics to find lines for each design. Knock on wood at least one is out there. Anyway, the workshops reflect updates.
