Monopoly Politics: Competition and Learning in the Evolution of Policy Regimes

Abstract. Motivated by the contemporary extremes of monopoly power in the United States and globally, this book uses an in-depth comparison of the United S

Good reporting on the South Shore raid from South Side weekly here.

Confirms one thing I was told but didn't put in my own piece because I didn't have a second source and it seemed too insane: border agents segregated arrested residents by race

Federal Agents Storm South Shore Building, Detaining Families and Children

Families were woken by flashbangs and helicopters as hundreds of federal agents raided their homes. Days later, neighbors are still searching for the missing.

The idea that people have been able to claim that Identifying public officials who are working for the state (which pays them with OUR tax dollars) is doxing is just 🤯!

hannah gais @hannahgais.bsky.social · 2d

Identifying public officials isn't "doxing." People have the right to know who is working for their government. Nor, for that matter, is it "radical left-wing terrorism." So it's frustrating to see platforms caving to these bad faith characterizations. www.technologyreview.com/2025/10/06/1...

Another way of looking at this same picture: The euro zone is a system that use the leverage of a central bank outside the control of national governments to force deep austerity on countries like Spain, which sent them into deep depressions that created fiscal deficits that didn't previously exist.

Robin Brooks @robin-j-brooks.bsky.social · 3d

The Euro zone is a system where fiscally responsible countries subsidize chronically irresponsible ones like Italy & Spain. This happens via open-ended, no-strings-attached transfers by way of joint EU debt issuance and periodic ECB yield caps. A system that will fail because incentives are broken.

9 months in, the pattern is clear:

1) If you tell Trump to pound sand, he often leaves you alone to look for weaker targets

2) If you give the authoritarian mouse the cookie, he will shake you down for a glass of milk again and again

If you still opt for #2, you're either a fool or a sympathizer

Poll after poll shows corruption is THE issue voters care about. And Jeffries goes out of his way to praise Adams, whose public corruption charges were dropped after Trump’s DOJ unceremoniously shut the case down?

Democrats have the winning hand right in front of them. Wild that they won’t play it.

statement titled “Leader Jeffries Statement on Mayor Eric L. Adams.” It says Democratic Leader Hakeem Jeffries thanked Adams for decades of service as an NYPD officer, state senator, Brooklyn Borough President, and New York City’s 110th mayor. The statement highlights achievements under Adams, including reduced violent crime, more affordable housing, and recovery from COVID-19. Jeffries acknowledges ongoing challenges like the high cost of living but says meaningful progress was made. He thanks Adams for his service and says that in the coming days his focus will shift to Republican healthcare and government funding issues, and that he will comment on the remaining mayoral candidates before early voting begins.

coming back to this, what are we even doing with this funding bill negotiation or indeed any budget at all?

Matt Ford @mford.bsky.social · 12d

Supreme Court rules 6-3 that congressional appropriations are optional: www.supremecourt.gov/opinions/24p...

On September 3, the United States District Court for the District of Columbia entered a preliminary injunction directing the Executive to obligate roughly $10.5 billion of appropriated aid funding set to expire on September 30. Of that $10.5 billion, $4 billion was proposed to be rescinded in a “special message” transmitted pursuant to the Impoundment Control Act. See 2 U. S. C. §681 et seq. After the District Court and the United States Court of Appeals for the District of Columbia Circuit denied stays of that order, the Government filed this application to stay the District Court’s injunction. The application for stay presented to THE CHIEF JUSTICE and by him referred to the Court is granted. The Government, at this early stage, has made a sufficient showing that the Impoundment Control Act precludes respondents’ suit, brought pursuant to the Administrative Procedure Act, to enforce the appropriations at issue here. The Government has also made a sufficient showing that mandamus relief is unavailable to respondents. And, on the record before the Court, the asserted harms to the Executive’s conduct of foreign affairs appear to outweigh the potential harm faced by respondents. This order should not be read as a final determination on the merits. The relief granted by the Court today reflects our preliminary view, consistent with the standards for interim relief.
