New blog post! In which I explain the issue with mediation analysis and sketch out one way to deal with the underlying causal inference problem -- in just a bit over 1,000 words!

Reviewer notes: That’s a very nice mediation analysis you have there. It would be a shame if something happened to it.
Mediation analysis has gotten a lot of flak, including classic titles such as “Yes, but what’s the mechanism? (Don’t expect an easy answer)” (Bullock et al., 2010), “What mediation analysis can (not) ...

The zoning process is more than just a map & a code. Many projects require special hearings & city council review.
In new research @urbaninstitute.bsky.social, I show that in Chicago, 58% of permitted housing units undergo that sort of discretionary review.

Markets gonna market!
Every student in Iowa will be eligible for a voucher next year, regardless of income. That amount is $7,826 this year.
So these Iowa private elementary schools increased tuition from $4780 in 2022-23 to $11,100 in 2025-26 - a 132% increase in just 3 years.

As school vouchers become available to all Iowa families, parents at a large private school operator in Dubuque are experiencing tuition sticker shock.

Highways are really awful barriers to the urban fabric, as we can all intuitively grasp
A cool paper this year used smartphone data to show that highways create a meaningful distortion in how people move around cities, especially for non-work trips

Does #randomization ensures balance of risk factors between groups? Consider this:
In Denmark 860 individuals were randomly allocated to either intervention or control. Individuals were unaware of their allocation. No intervention took place. Mortality was higher in the intervention group (p=0.003)
