Important thread. Is the econ profession about to get flooded with a bunch of good-looking papers of dubious or hard-to-ascertain quality?

In macro, this already happened ~20 years ago with DYNARE. Over night it became very hard to publish macro-theory papers, and the field split apart.

A bird's-eye view of a former Auschwitz II-Birkenau camp showing a wide dirt pathway flanked by parallel rows of barbed-wire fences. Groups of visitors walk along the path, surrounded by the remnants of brick structures and barracks, now reduced to foundations. Green grass contrasts with the somber history of the site, as the path leads toward a guard tower in the distance.

Auschwitz was at the end of a process. We must remember that it did not start from gas chambers.

This hatred gradually developed: from ideas, words, stereotypes & prejudice through legal exclusion, dehumanization & escalating violence... to systematic and industrial murder.

Auschwitz took time.

This line graph illustrates the percentage change in agency staff levels from the previous year for nine major U.S. federal scientific and health organizations between the fiscal years 2016 and 2025. The agencies tracked include the CDC, Department of Energy, EPA, FDA, NASA, NIH, NIST, NOAA, and NSF. For the majority of the timeline between 2016 and 2023, the agencies show relatively stable fluctuations, generally staying within a range of +5% to -5% change per year. However, there is a dramatic and uniform plummet starting in the 2024–25 period. Every agency depicted shows a sharp downward trajectory, with staffing losses ranging from approximately -15% to over -25%. The Environmental Protection Agency (EPA) shows the most significant decline, dropping to roughly -26%, while the National Institute of Standards and Technology (NIST) shows the least severe but still substantial drop at approximately -15%.

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again.

Chinese leader Xi Jinping hails 'turnaround' in China-Canada ties as Mark Carney visits Beijing Trade tops the agenda in what is a Canadian leader's first visit to China after years of strained ties.

Canada has agreed to allow 49k Chinese EVs into the Canadian market, with the most-favored-nation tariff rate of 6.1%.
As Canada intends to double its energy grid capacity and move towards clean power, the prime minister also welcomed China to invest in his country in these areas.

It begins. Canadians will soon experience the vast superiority of Chinese EVs, and the US will lose its largest vehicle export market. The transition will happen much faster than people think.

German industry association proposes “mandatory charging” for PHEVs - electrive.com The VDA (Verband der Automobilindustrie, Germany’s main automotive industry association) is known for advocating that new plug-in hybrids (PHEVs) should

Policy ideas are evolving fast: German industry groups are proposing mandatory charging for PHEVs to boost real-world EV use, showing how evidence like ours feeds directly into policy debate.

Since PHEVs drive in electric mode for only half the distance suggested by official test cycle values,
fuel prices are effective in improving the environmental performance of these vehicles.

When fuel prices rise, PHEVs reduce fuel consumption more than gasoline and diesel cars. They do not proportionally
reduce their mileage; instead, they increase electric charging: evidence policymakers need as real-world emissions face scrutiny.

The brilliant Kate Ho has passed away.

She was an amazing economist and a genuinely kind human being. Her work shaped how we think about healthcare markets and her generosity touched everyone lucky enough to know her.

The profession and the world are poorer without her.

A new article in the WSJ on reverse acquihires. The main point it makes is that one group that loses out in a reverse acquihire are the employees who are left behind. This will make it more difficult for future startups to attract employees.

Just as dog whistles are high pitched so as to be only heard by dogs, some academic papers now have prompts for large language models invisibly inserted, in case the referee is a nLLM.

Shift Key podcast episode: the U.S. auto industry wasn't built for tariffs

Trump may have given Canada & Mexico a brief reprieve, but talk of tariffs is rattling the economy and forcing a rethink of key industries & supply chains. Chief among them: the North American auto industry. This week on SHIFT KEY, we talk to Ford's former chief economist about Trump's tariffs. 🔌💡

While most of the cost in a traditional car is the engine, most of the cost in an electric car is somewhere else: the battery.
And this is disastrous for Europe.
Because a) we don't make many batteries and b) making batteries is a v v different skill to making engines
