Falling Birth Rates Haven't Hurt Economic Growth — and the Reason Why Should Reassure Us About the Future

voxeu

• Seven decades of cross-country and U.S. regional data show that lower birth rates are actually associated with higher GDP per worker and faster wage growth, contradicting widespread fears that aging, shrinking populations doom economies to stagnation.
• The likely mechanism: labor scarcity caused by fewer young workers pushes companies and countries toward labor-saving innovation, with low-fertility countries showing the largest shifts toward high-tech exports, R&D-intensive industries, and automation patents.
• The authors caution that future demographic shifts — especially in China, where the working-age population could fall from 1 billion to 300 million by 2100 — will be far faster and larger than anything in the historical record, so current optimism shouldn't be taken as a guarantee.

Economists Show Why a Price Cap on Russian Oil Can Actually Increase Supply and Lower Global Prices

aea

• Standard economic intuition says price caps reduce production, but a new paper in the American Economic Review argues the opposite applies to Russia: capping oil prices strips away Russia's incentive to withhold supply and drives it to pump more oil to fund the war.
• A perfectly enforced $60/barrel cap could cut Russia's oil revenues by the equivalent of wiping out more than half its reserves while simultaneously keeping global prices stable — achieving both goals of sanctions policy at once.
• The real-world catch is leakage: as Russia shifted two-thirds of sales to a shadow fleet outside the cap, it regained the ability to exercise market power, reintroducing the risk of global price spikes that the cap was designed to prevent.

The U.S. Government Shut Down an AI Model With No Clear Rules. Congress Needs to Fix That.

atlantic_council

• The Commerce Department ordered Anthropic to cut off access to its Fable 5 AI model for all foreign nationals, with just 90 minutes' notice, after researchers found a way to bypass its safety guardrails — but no specific threat was publicly disclosed and the entire process happened behind closed doors.
• The action was a poor fit for existing export control tools, which target specific prohibited uses rather than pulling an entire deployed service offline, and the resulting deal between Anthropic and Commerce was negotiated privately with no public criteria.
• The author argues Congress should establish transparent, public standards for when the government can restrict a deployed AI model, clarify which agencies have authority, and require written findings and congressional notification before any emergency shutdown.

The Case for Letting Oman and Europe — Not Washington — Reopen the Strait of Hormuz

atlantic_council

• More U.S. airstrikes won't budge Iran: the regime has repeatedly shown it will absorb punishment rather than capitulate, and now holds two points of leverage — its nuclear program and control of the Strait of Hormuz.
• The article argues the best path forward is to convince Oman, as the strait's other bordering state, to assert equal sovereign claim over it, undercutting Iran's unilateral grip.
• Oman could then invite a European-led naval mission into its waters, forcing Iran to choose between attacking a multinational coalition or accepting a force that neutralizes its newest bargaining chip.

US avocado import rules accidentally cleaned up Mexico's water — and it holds lessons for future trade deals

the_conversation

• When the US expanded avocado import rules in 2016 to require strict phytosanitary certification, Mexican growers reduced pesticide use to avoid shipments being rejected at the border — and that led to less fertilizer use and less nitrogen pollution in nearby waterways.
• Researchers comparing avocado-growing municipalities to similar non-growing ones found nitrogen concentrations in waterways fell about 10% after the 2016 rules took effect, suggesting the trade agreement — not other factors — drove the improvement.
• The finding challenges the "pollution haven" theory that wealthy countries simply export environmental damage, and suggests well-designed trade conditions can improve environmental outcomes in exporting countries.
