Most long-run estimates of U.S. intergenerational mobility only include white men. What does mobility over the 20th century look like when we include non-whites *and* women? A thread on my new paper with @ikuziemko and @snaidunl

Retrospective power analyses demonstrate that most studies were underpowered to detect all but large effect sizes. We conclude that many published findings using the RD design are exaggerated if not altogether spurious. [4/4]

We show that the literature demonstrates some pathological behavior consistent with selective reporting of findings. The figure below demonstrates that findings cluster just at or just above the t-statistic threshold of 1.96 (i.e. a p-value of less than or equal to 0.05). [2/4]

New paper with @caryfrydman in Management Science. Summary: Slow choices generally signal uncertainty. So, when people see others choosing slowly, they tend to ignore those choices and follow their own private information. This helps them to avoid “herding” on bad choices. 1/5

Thrilled to see our paper coming out with @SakiBigio Standard macro models assume the central bank controls a single interest rate that guides all saving/borrowing decisions of all agents. But the target rate for the Fed and many central banks is the interbank market rate.

The plumbing of monetary policy matters for macro. We develop a model of the transmission and implementation of monetary policy and show that how a central bank implements the target for the interbank market rate affects credit and economic activity https://t.co/jl9651Njs9 https://t.co/eQlqJzGDNB

Despite a massive increase in demand for higher ed over the last 30 years, "supply" at elite colleges has stayed basically the same. When ranked on SAT scores, colleges in the 1-98% range have met demand while elite colleges' share of total enrollment has been shrinking.

I'm going to write a blog post on the pros and cons that economists (PhD students, post-docs & faculty) considering joining Twitter should know about. #EconTwitter, what are your biggest pros and cons? (The ability to pose questions like these will clearly be listed as a pro!)

Excited & slightly terrified that all materials & videos of my MIT undergrad psychology & economics course (aka behavioral econ) from Spring 2020 are online on OCW! As an undergrad, I loved browsing OCW classes. I hope this one will be useful for others!

This course covers recent advances in behavioral economics by reviewing some of the assumptions made in mainstream economic…

After advising PhD & Master students for over a decade, there is one thing I find most students need to unlearn: the half-ass work mentality acquired during years of tests and homework. Let me explain (thread 🧵). 1/N #AcademicTwitter

The discussion around this thread suggests that many economists use “utility” in senses other than what the theory supports. Economics is not based on the idea that people maximize life satisfaction, or maximize pleasure minus pain. vNM utility is not hedonic utility!

I don’t like phrases of the form “agents derive utility from the common good” or “agents derive utility from the well-being of others.” Better replacements are “agents care about the common good” or “agents care about the well-being of others”

This is completely wrong but in an interesting way. See if your principles or intermediate micro students can answer. #EconTwitter

Psaki seems right to me. If a company had the power to raise prices at a higher tax level, why wouldn't it raise prices now at current levels? Either the pricing power exists or it doesn't. https://t.co/OYXOLz5uXT
