A tax on remittances is basically a tax on global poverty reduction. It must be one of the most regressive policies being considered by the current admin, yet I haven't seen much discussion or analysis

House Republicans’ proposed tax on remittances spooks financial sector
“This came totally out of nowhere,” one cryptocurrency executive told Semafor.

One of my best students just had his funding offer for a PhD in the US withdrawn. Meanwhile we've had a massive surge in applications to our program from really strong US and international students. It feels like a shift is already underway.

Probably better off creating an index if the goal is dimensionality reduction.

Comments welcome! We are currently working on a more econ-audience version of this paper which will replicate a few existing studies that use remotely sensed dependent variables.

We outline several other ways this type of error can occur in the paper, and propose methods for fixing it - described by @lcsanford.bsky.social in his thread above.

Another example - say you are measuring air pollution using satellite data. We know that satellite measures of pollution saturate at higher concentrations. If your treatment only has an effect in highly polluted areas, the satellite data might detect no change, even if there was an effect.

Imagine that you are measuring deforestation and your ML model sometimes confuses forests for irrigated cropland. If your treatment affects cropland, this might mistakenly look like an increase in forest to your model.
mdgordo.bsky.social
But it is really differential measurement error that matters - errors that are correlated with treatment status. How can this happen, even in an RCT?
mdgordo.bsky.social
One thing that sometimes surprises people, is that, even in an experimental setting, treatment effects can be biased if the dependent variable has measurement error. This is clearly the case if the dependent variable is a prediction from a machine learning model.

Check out our new working paper on using techniques from the algorithmic fairness literature to correct machine learning prediction errors in a causal inference setting.

A recent report showed that the destruction of just one USAID program, the anti-AIDS PEPFAR initiative, would lead to the deaths of one million people *every year* www.vox.com/future-perfe...

PhD students consider submitting to our annual conference run by and focused on doctoral students in economics. April is a nice time to visit Paris

In 2015 Pakistan was signing 30 year contracts with coal producers. That was the year solar became cheaper than coal.

Lecture slides for 'Air Pollution and Welfare' this week. I try to use the topic to teach an appreciation for synergies between reduced form and structural methods:

I'm on the job market! My #EconJMP examines climate adaptation inequality in labor markets (see ⬇️).

This is part of my research on the effects of climate change/plastic pollution on workers & society - often with unique data & an interdisciplinary lens.

PSE is hiring for two positions this year - applications due next week: www.parisschoolofeconomics.eu/en/job-oppor...

Reupping my thread from last year about why Americans should consider applying.
