The president just gathered the highest ranking officers in the military to tell them that he may order them to kill American citizens -- and that they better follow his orders. All in response to a series of crises that have no basis in reality.

I don't know how to yell any louder.

PhD students underestimate the value (and difficulty) of writing well.

Hiring faculty skim dozens of JMPs in a short time. If your contribution is unclear, you will get fewer interviews.

Higher costs from the new tariffs will be felt across sectors of the economy, from housing and health care to logistics. The president also said the United States would begin imposing a 50 percent tariff on imported kitchen cabinets, bathroom vanities and associated products, along with a 30 percent tariff on imported furniture and a 25 percent tariff on foreign trucks.

The tariffs will be issued under a national security related law, known as Section 232, that Mr. Trump has used to issue tariffs on steel, aluminum, cars and copper. On Wednesday, the Trump administration announced that it was beginning new investigations under the law into imports of robotics, industrial machinery and medical devices, which could result in tariffs.

How Do Restrictions on High-Skilled
Immigration Affect Offshoring?
Evidence from the H-1B Program
Britta Glennon
WORKING PAPER 27538
DOI 10.3386/w27538
ISSUE DATE July 2020
REVISION DATE February
2023
Highly-skilled workers are not only a crucial and relatively scarce inputs into firms' productive and innovative processes, but are also a critical resource determining competitive advantage. An increasingly high proportion of these workers in the US were born abroad and permitted to work on skilled worker visas. How do multinational firms respond when artificial constraints, namely policies restricting skilled immigration, are placed on their ability to hire scarce human capital? This paper combines visa microdata and comprehensive data on US multinational firm activity to demonstrate that firms respond to restrictions on H-1B immigration by increasing foreign affiliate employment at the intensive and extensive margins, particularly in China, India, and Canada. The most impacted jobs were R&D-intensive ones, but there is some evidence that non-R&D employment was also affected. The paper highlights a means by which firms can circumvent constraining policies and mitigate country-level risk, but it also suggests that, for the average MNC, this means is imperfect; for every visa rejection, they hire 0.4 employees abroad. The most globalized MNCs are the most likely to respond to these restrictions by offshoring, highlighting that firm capabilitiesβ€”in the form of prior internationalization-shape the decision and ability to offshore in response to skilled immigration restrictions; indeed, these firms hire 0.9 employees abroad for every visa rejection. More broadly, the paper provides evidence of a push factor for internationalizing knowledge activity: artificial constraints on resources result in firms circumventing restrictive policies in ways that may not be anticipated by policy makers.

Restricting visas doesn’t lead to hiring non-immigrantsβ€”it leads to hiring foreigners. For every H-1B visa rejection, multinationals add ~0.4–0.9 foreign employees, especially in R&D hubs like India, China, and Canada.

"Young ordered the restoration of $783 million in federal funding for fiscal year 2025 β€” a portion of which, totaling millions, was allocated to Harvard β€” before the Supreme Court stayed the order nearly two months later. (The total multi-year funding pool affected by Young’s ruling included $3.8 billion in grants, many of which were partially paid out before the freeze. According to a Crimson analysis of court filings, Harvard was awarded more than 140 grants within that pool, with a combined multi-year value exceeding $60 million.)

Harvard expected the grants listed in Young’s ruling to flow back to researchers, according to a person familiar with the matter, even though the White House had imposed a block on all Harvard grants as part of its initial funding cut in April.

But the funds never arrived, and Harvard wrote in an August press release from the School of Public Health that the NIH was continuing to β€œblock disbursement of any funds to Harvard University.”

According to one person, Harvard has been unable to access any funds from the NIH since April because of the restrictions imposed by DOGE through its oversight of the NIH’s payment system, including in the two-month period in which Young’s ruling mandated that grant awards listed in the ruling be resumed."

Student Arrivals to US Continue to Plummet, With Asia Hit Especially Hard Visitors to the US arriving on student visas plunged in July, falling year-on-year for a fourth straight month.

Your occasional reminder -- as arrivals on student visas decrease 28% -- that tuition from foreign students counts as an export, which means that every rejected student visa is going to contribute to the US trade deficit.
