Three US-based academics yesterday won the Nobel Prize in Economics for research that revolutionized empirical work in their field and brought better understanding of how labor markets work, the jury said.
Canadian David Card, Israeli-American Joshua Angrist and Dutch-American Guido Imbens shared the prize for providing new insights about the labor market and showing “what conclusions about cause and effect can be drawn from natural experiments,” the Nobel committee said in a statement.
Card’s work has focused on the labor market effects of minimum wages, immigration and education. Angrist and Imbens demonstrated how precise cause and effect conclusions can be.

Half of the 10 million kronor (US$1.14 million) prize went to Card, a professor at the University of California, Berkeley, who was born in Canada in 1956, for his empirical contributions to labor economics.
The other half went jointly to Angrist, 61, a professor at the Massachusetts Institute of Technology, and Imbens, 58, a professor at Stanford University, “for their methodological contributions to the analysis of causal relationships.”
“I was absolutely stunned to get a telephone call,” Imbens told reporters during a telephone interview following the announcement.
“Josh Angrist was actually the best man at my wedding so he is a good friend, both professionally and personally, and I’m just thrilled to share the prize with him and David,” he said.
The three laureates “have revolutionized empirical work in economics. They have shown that it’s indeed possible to answer important questions, even when it’s not possible to conduct randomized experiment,” Nobel Committee member Eva Mork told reporters in announcing the prize.
The trio was honored for their work using so-called “natural experiments,” in which chance events or policy changes result in groups of people being treated differently, in a way that resembles clinical trials in medicine.
The economics prize, officially the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, was the only prize not among the original five set out in the will of Nobel, who died in 1896. It was instead created through a donation from the Swedish central bank in 1968.
Just like this year, the economics prize has generally been male-dominated. It has only been awarded to two women in history, Elinor Ostrom in 2009 and Esther Duflo in 2019.
The combined effect of the monsoon, the outer rim of Typhoon Fengshen and a low-pressure system is expected to bring significant rainfall this week to various parts of the nation, the Central Weather Administration (CWA) said. The heaviest rain is expected to occur today and tomorrow, with torrential rain expected in Keelung’s north coast, Yilan and the mountainous regions of Taipei and New Taipei City, the CWA said. Rivers could rise rapidly, and residents should stay away from riverbanks and avoid going to the mountains or engaging in water activities, it said. Scattered showers are expected today in central and
COOPERATION: Taiwan is aligning closely with US strategic objectives on various matters, including China’s rare earths restrictions, the Ministry of Foreign Affairs said Taiwan could deal with China’s tightened export controls on rare earth metals by turning to “urban mining,” a researcher said yesterday. Rare earth metals, which are used in semiconductors and other electronic components, could be recovered from industrial or electronic waste to reduce reliance on imports, National Cheng Kung University Department of Resources Engineering professor Lee Cheng-han (李政翰) said. Despite their name, rare earth elements are not actually rare — their abundance in the Earth’s crust is relatively high, but they are dispersed, making extraction and refining energy-intensive and environmentally damaging, he said, adding that many countries have opted to
SUPPLY CHAIN: Taiwan’s advantages in the drone industry include rapid production capacity that is independent of Chinese-made parts, the economic ministry said The Executive Yuan yesterday approved plans to invest NT$44.2 billion (US$1.44 billion) into domestic production of uncrewed aerial vehicles over the next six years, bringing Taiwan’s output value to more than NT$40 billion by 2030 and making the nation Asia’s democratic hub for the drone supply chain. The proposed budget has NT$33.8 billion in new allocations and NT$10.43 billion in existing funds, the Ministry of Economic Affairs said. Under the new development program, the public sector would purchase nearly 100,000 drones, of which 50,898 would be for civil and government use, while 48,750 would be for national defense, it said. The Ministry of
UNITED: The other candidates congratulated Cheng on her win, saying they hoped the new chair could bring the party to victory in the elections next year and in 2028 Former Chinese Nationalist Party (KMT) lawmaker Cheng Li-wun (鄭麗文) yesterday won the party’s chair election with 65,122 votes, or 50.15 percent of the votes. It was the first time Cheng, 55, ran for the top KMT post, and she is the second woman to hold the post of chair, following Hung Hsiu-chu (洪秀柱), who served from 2016 to 2017. Cheng is to succeed incumbent Eric Chu (朱立倫) on Nov. 1 for a four-year term. Cheng said she has spoken with the other five candidates and pledged to maintain party unity, adding that the party would aim to win the elections next year and
