New mini-series on ML and Econometrics! Covers ML basics, double/debiased ML, post-double-selection LASSO, and other applications. Main focus is on preserving appropriate econometric inference when utilizing ML. 9-videos playlist here: youtube.com/watch?v=Y2HgL7rA…

New mini-series on sensitivity analysis and partial identification! Covers limits of IV and how to bound causal effects in OLS regression models. Very useful; give it a look if you're interested. youtube.com/watch?v=zjwznLCy…

Brand-new mini-series: this is an 8-parter on learning models in economics. Topics include: - What is learning - What is Bayesian updating - Generalizations beyond Bayesian updating - Multidimensional learning - Recent empirical papers about learning youtube.com/watch?v=zrQVqqNg…

New 8-part YouTube series on factor models & measurement error is now posted! Covers PCA, factor analysis, identification, maximum likelihood estimation, and Heckman's work on cognitive/non-cognitive skills + frontier papers. Check it out! youtube.com/playlist?list=PL…

Just dropped a new 4-part video series covering model assessment and counterfactual simulation. Covers model fit, validation, and counterfactual simulation. Playlist here: youtube.com/watch?v=2n-2HMIb…

New mini-series on Conditional Choice Probability (CCP) estimation for dynamic discrete choice models! Covers Hotz-Miller inversion, renewal actions, finite dependence, unobserved heterogeneity, and more. Watch here: youtube.com/watch?v=WQIM47u1…

Finished another video series! This one: dynamic discrete choice models and optimal stopping. Bellman equations, backward recursion, value function iteration, and why John Rust's 1987 bus paper is a masterpiece. Watch here: youtube.com/watch?v=g3agdg9M…

Another mini-series is live! This one is on mixed logit & preference heterogeneity. It covers: • random coefficients • identification • simulation methods (quadrature vs MC) • finite mixtures • EM/MM algorithms • practical implementation Enjoy! youtube.com/playlist?list=PL…

New 7-part series on nested logit models! It covers the full pipeline from GEV error structures through estimation and real-world applications. Ideal if you've always wondered about nested logit but felt too intimidated to jump in! youtube.com/watch?v=-QECdbQO…

I just finished an 8-part YouTube series on discrete choice models! It covers the full pipeline from random utility → logit derivation → MLE → welfare analysis. Each video builds on the last with both math and intuition. Enjoy! youtube.com/playlist?list=PL…

I just posted a new 8-video YT playlist covering the process of producing an empirical structural model. In each video, I go through a (contrived) example of each step in hopes of elucidating the process. youtube.com/playlist?list=PL…

The reduced form vs. structural debate is a non-starter. A school voucher study in India shows why: neither method alone could answer the key policy question. When researchers combined both approaches, they found *new* mechanisms! Video: youtu.be/BMYrFhasj64

I had a lot of fun with my latest video tracing the structural vs. reduced form "war" in applied microeconomics! (credit: @causalinf's history series). Check out how the war got started, who the key figures were, and why I believe it's (mostly) over: youtu.be/N4vEM3CNC5s

My latest video explores a paradox of empirical economics: "credibility" ultimately rests on untestable assumptions. Parallel pre-trends ≠ proof of parallel post-trends Model fit ≠ proof of correct specification New video exploring why 👇 youtu.be/cRyuBCFbyYY

🚀 What do Galileo, Newton & Einstein teach us about economics? Galileo experimented, Newton modeled, and Einstein refined. Economics evolves the same way. 🎥 youtu.be/_qd_NXDXzGE #Economics #Science #EmpiricalMethods

When should you use a structural model vs. a simple RCT or diff-in-diff? It depends on whether you're evaluating existing policies or designing new ones. New video breaking down the tradeoffs: youtu.be/CoLWdN0CU_A?si=cdB_…

Have you ever wondered about the difference between "reduced form" and "structural" econometrics? This video takes cues from @PhilHaile and argues that both methods exist on a single spectrum. youtu.be/K7XSiH98nuU?si=kePx…
