📰 Do the effects of partisan media fade quickly or accumulate over time? ➡️ Using multiwave experiments, M Baum et al. show a single exposure can have effects lasting up to a week, while cumulative effects are hard to detect www.cambridge.org/core/journal... #FirstView

My friend and colleague at @harvardkennedy.bsky.social @tedsvo.bsky.social shared his expert perspective on the use of AI in education on @npr.org ’s All Things Considered today: www.wbur.org/upnext/2025/...
How one college professor uses AI in the classroom
Harvard Kennedy School Professor Teddy Svoronos is mostly optimistic on the benefits of AI in higher education.

Yet again, Trump is falsely claiming that Democrat-controlled cities like DC are letting crime get out of control. Our research – from cities across the US – shows that this just isn't true @chriswarshaw.bsky.social @dbjones.bsky.social @matttheeconguy.bsky.social
Trump mentions NYC, Baltimore, and Oakland, says "they're so far gone," and adds, "this will go further. We'll starting very strongly with DC."
Crime is nonpartisan, and neither party is better at fighting crime in cities. But evidence-backed programs like youth jobs initiatives can help improve public safety. buff.ly/RGmW1ht @jdbk.bsky.social @harvardkennedy.bsky.social and Christopher S. Warshaw, George Washington University #polisky
Crime is nonpartisan and the blame game on crime in cities is wrong – on both sides
Mayors from the Democratic Party aren’t making cities any more – or less – dangerous than mayors from the Republican Party.

Well said, from my colleague David Deming @harvardkennedy.bsky.social: "If government funding goes away, so will much of the research. The long-run cost will be staggering. We’ll have fewer medical breakthroughs, the progress of lifesaving medical treatments will stall, and America may fall behind."
The Trump administration’s cuts to university research grants will make America sicker and poorer in the long run, David Deming writes. DOGE should stop "confusing efficiency with ill-conceived budget cuts."
Are Democratic leaders making cities more dangerous than Republicans? Trump + others have repeatedly made claims like this. New paper in Science Advances w/ @chriswarshaw.bsky.social, Dan Jones & Matt Harvey shows that, in short, the answer is no.

Can developers compensate nearby residents to win support for their housing projects? In a new @jpublicpolicy.bsky.social article, @jdbk.bsky.social and I unpack how compensation works, when it fails, and what that teaches us about symbolic attitudes and housing policy. 1/11

Great to have the culmination of 8+ years collecting election data finally published! Excited to see these data help the next generation of scholars working on local politics 🤓
Our paper introducing the "American Local Government Elections Database" is online at Scientific Data. The data includes 78,000 candidates in 57,000 electoral contests in races for seven distinct local political offices in most medium and large cities and counties over the last three decades.
Lots of discussion on how economy will affect 2024 election. Evidence indicates that election year economy matters a lot (esp. real wage growth), but the economy this year prob. doesn't matter much. So a lot depends on what happens next year! See this figure from my paper w/ @jdbk.bsky.social.
