🧵 (1/7) With @knittelmit.bsky.social and @cwolfram.bsky.social, happy to announce our new paper on “Who Bears the Burden of Climate Inaction?”, just posted for BPEA @brookings.edu.

We find large climate cost impacts that vary by both geography and income.

My theory is that he views everything through the lens of zero-sum games. He can get away with that with real-estate transactions for the most part.

Then they came after the naturalized citizens' speech,
whose status could still be questioned,
and I did not speak out—
because I was born here.

Then they came after my speech—
and there was no one left to speak for me.

Then they came after the green card holders' speech,
who had nearly all constitutional protections, and I did not speak out—
because I was not a permanent resident.

Then they came after the visa holders' speech,
who had limited protections under the Constitution,
and I did not speak out—
because I was not on a visa.

First they came after the undocumented immigrants' speech,
who had few constitutional protections,
and I did not speak out—
because I was not undocumented.

Frying a turkey in a log cabin in the middle of a New Hampshire forest? What can go wrong!? At least there isn’t an open flame.

A quick calculation on #Trump's #tariffs. We import ~$900B from Ca and M. 25% tariff. Assume a 75% pass-through (low?), that's a $1,000 tax on the avg US household. We import $430B from China. 10% tariff => $250/HH.

Here comes a $1,250/year tax on US households?

Hey #energysky #econsky #academicsky,

If you haven't tried, try #Google's #NotebookLM podcast feature. Just upload a paper and hit go. I plan to use these for my class. It seems to do a decent job at AI generating the podcast.

Implications for Platforms: Simple, evidence-based design tweaks can significantly curb bias without overhauling systems. Also, and totally self-serving, collaboration between platforms and researchers is key to tackling systemic discrimination.

Looking forward to your thoughts!

Broader Impacts: Highlighting quality metrics not only reduced bias but also increased pickups in areas with a higher share of African American residents. This suggests that thoughtful design can enhance equity and access.

Unexpected Insights: Showing names upfront didn’t strongly reduce bias. Possible reasons:

Drivers might not process names pre-acceptance.

Habitual biases tied to name recognition remain strong.

Why the Rating-Font Treatment Worked: We believe (although more work to be done) highlighting passenger quality shifted driver focus away from biased heuristics (e.g., names) and toward objective measures (ratings). Small changes can drive big behavioral shifts.

Second, can minor interventions help?
Increasing the font size of ratings reduced cancellations by 71.7%, effectively eliminating racial bias.
Displaying names upfront? Less effective. While there was a 30% reduction, it wasn’t statistically significant.

Key Findings:
First, we confirm the previous work. In the control group, drivers were more likely to cancel rides when passenger names were associated with African Americans.
