I have now posted 14 decks of slides covering a lot of DiD materials.
I also want to add a few more decks:
- Triple Differences
- DiD with Continuous Treatment
- Instrumented DiD
- Synthetic DiD and related extensions
- Heterogeneity analysis in DiD
I also want to add more applications to these!

New feed just dropped.
Econ conference feed displays posts with #EconConf or #AEA, #2025AEA, #AEA2025, #AEA25 & similar for APPAM, ASHE, LERA, SEA, & SOLE. Displays posts from last 7 days.
Better than different feeds for each conference, each active just 1 week a year?

Today, I will talk very briefly about a few recent methodological papers that I think are super useful to applied researchers. Basically, below, you will find some new tools that may help you to answer relevant empirical questions.

Just back from giving a talk to 2nd year students on how to approach research, how to write a paper. Abhijit was coming after me (good thing he didn't go first, tough act to follow!)

Just finished making a monster slideshow aimed at covering the basics of measuring poverty. It has a tilt towards Canadian content, but is pretty general and is for an intro international development MA course. Slides are temporarily here in case anyone wants them: www.dropbox.com/scl/fi/q3f4l...
