A message from Professor David E. Weinstein:

It is with profound sadness that we share the news of Professor Takatoshi Ito’s passing. Taka was the director of the Program on Public Pension and Sovereign Funds at the Center on Japanese Economy and Business (CJEB) at Columbia Business School and a professor at the School of International and Public Affairs (SIPA) at Columbia University.

Taka was a giant in the field of international macroeconomics. He authored the definitive book on the Japanese economy that trained generations of students and scholars, along with countless research articles, policy reports, working papers, and op-eds, and actively shaped discourse in the field through his editorial oversight. His contributions to our understanding of Japan’s economy and to policy earned him two imperial medals: the National Medal with Purple Ribbon and the Order of the Sacred Treasure, Gold Rays with Neck Ribbon. He collaborated extensively on academic, government, and private sector projects in Japan, the United States, and worldwide, with institutional commitments spanning decades and transcending national borders. He has left an indelible mark at CJEB through the programming he helped shape at the Center—notably his annual lecture on the Japanese economy, the Program on Public Pension and Sovereign Funds, and the Japan Economic Seminar—as well as the network of thought leaders he introduced to our audience. He was beloved by the CJEB faculty, staff, Visiting Scholars, sponsors, and indeed our entire constituency, particularly Columbia’s student and alumni community. I will remember him most as a mentor, good friend, and colleague throughout my entire academic career. He was a gentleman and a scholar, and he will be sorely missed at Columbia, at CJEB, and in the world of economics.

Blog Post Co-Authored by CJEB’s Director, Professor David Weinstein, Has Been Widely Cited in Prominent Publications

A research blog post co-authored by CJEB's Director, Professor David Weinstein, “Who Is Paying for the 2025 U.S. Tariffs?” was published on the Liberty Street Economics blog, which features insight and analysis from New York Fed economists working at the intersection of research and policy. The post and its contents have been widely cited in over 100 articles, including prominent publications such as the Wall Street Journal, the New York Times, the Financial Times, and many more. A selected list of these and other articles referencing the post and its contents is included below.“Who Is Paying for the 2025 U.S. Tariffs?”  begins with this text to explain what it covers: “Over the course of 2025, the average tariff rate on U.S. imports increased from 2.6 to 13 percent. In this blog post, we ask how much of the tariffs were paid by the U.S., using import data through November 2025. We find that nearly 90 percent of the tariffs’ economic burden fell on U.S. firms and consumers.”US Firms Paid Nearly 90% of 2025 Tariff Costs, NY Fed Study Says (Bloomberg, 2/12/2026)https://www.bloomberg.com/news/articles/2026-02-12/us-firms-paid-nearly-90-of-2025-tariff-costs-ny-fed-study-saysTrump Plays Risky Political Game on Tariffs Ahead of Midterms (Bloomberg, 2/12/2026)https://www.bloomberg.com/news/articles/2026-02-12/trump-plays-risky-political-game-on-tariffs-ahead-of-midterms US businesses and consumers pay 90% of tariff costs, New York Fed says (Financial Times, 2/12/2026)https://giftarticle.ft.com/giftarticle/actions/redeem/7de0cca1-b592-4d63-a819-daeaa9d20639  Americans Are Paying the Bill for Tariffs, Despite Trump’s Claims (The New York Times, 2/12/2026)https://www.nytimes.com/2026/02/12/business/economy/americans-pay-tariffs-trump-fed.html?unlocked_article_code=1.L1A.9JSO.dIMgfYtVvXWs&smid=url-shareInflation measure falls to nearly five-year low as gas prices fall and housing costs cool (Associated Press, 2/13/2026)https://apnews.com/article/inflation-trump-economy-prices-d489cfa4b48e32232f136830333d1db0Trump Trade Team Working to Narrow Scope of Metals Tariffs (Bloomberg, 2/13/2026)https://www.bloomberg.com/news/articles/2026-02-13/trump-trade-team-working-to-scale-back-scope-of-metals-tariffsTrump plans to roll back tariffs on metal and aluminium goods (Financial Times, 2/13/2026)https://www.ft.com/content/f2eff736-12de-4c33-9826-847d2fdf8be3    "U.S. Inflation Eased at Start of the Year " (The New York Times, 2/13/2026)https://www.nytimes.com/2026/02/13/business/inflation-cpi-report-january.htmlYou’re Paying 90% of Trump’s Tariffs (The Wall Street Journal, 2/13/2026)https://www.wsj.com/opinion/donald-trump-tariffs-consumers-new-york-federal-reserve-study-95bed1bc Trump’s Broad Use of Metals Tariffs Starts to Backfire, Requiring a Rethink (Bloomberg, 2/16/2026)https://www.bloomberg.com/news/newsletters/2026-02-16/trump-to-scale-back-steel-tariffsWH adviser Hassett urges 'discipline' for Fed economists over tariff study (Associated Press, 2/18/2026)https://apnews.com/article/trump-federal-reserve-hassett-2329928f9e19b73472fbdc8d961db8d4Hassett Attacks NY Fed for Study on Tariff Burden Hitting US (Bloomberg, 2/18/2026)https://www.bloomberg.com/news/articles/2026-02-18/hassett-attacks-ny-fed-for-study-on-tariffs-hurting-us-companies-mls3r5yiTrump adviser says NY Fed economists should be ‘disciplined’ for publishing study on tariffs (Financial Times, 2/18/2026)https://giftarticle.ft.com/giftarticle/actions/redeem/cdec78a4-2034-40c5-b81e-3df40efad287Trump adviser Hassett suggests New York Fed researchers be punished for tariffs argument (Reuters News, 2/18/2026)https://www.reuters.com/world/us/trump-adviser-hassett-suggests-new-york-fed-researchers-be-punished-tariffs-2026-02-18/Fed Minutes Show No Rush to Restart Rate Cuts (The New York Times, 2/18/2026)https://www.nytimes.com/2026/02/18/business/economy/fed-officials-minutes-interest-rates.htmlWhite House Economic Adviser Criticizes NY Fed Finding on Tariffs (The Wall Street Journal, 2/18/2026)https://www.wsj.com/livecoverage/stock-market-today-dow-sp-500-nasdaq-02-18-2026/card/white-house-economic-adviser-criticizes-ny-fed-finding-on-tariffs-dGFOcjM0fiV8ojOmTPpRTariffs paid by midsized US firms tripled last year, new analysis from JPMorganChase Institute shows (Associated Press, 2/19/2026)https://www.kob.com/ap-top-news/tariffs-paid-by-midsized-us-firms-tripled-last-year-new-analysis-from-jpmorganchase-institute-shows/Kashkari Rips Hassett Criticism of NY Fed Tariff Analysis (Bloomberg, 2/19/2026)https://www.bloomberg.com/news/articles/2026-02-19/kashkari-rips-hassett-criticism-of-new-york-fed-tariff-analysisDonald Trump’s tariffs exert heavy burden on midsized US companies (Financial Times, 2/19/2026)https://giftarticle.ft.com/giftarticle/actions/redeem/d15b63ed-2f32-4a48-b86b-f327f6111cc6Top Fed official says White House is escalating its assault on central bank (Financial Times, 2/19/2026)https://giftarticle.ft.com/giftarticle/actions/redeem/7c5adca1-1554-409b-8823-4c1c977a316dMentioned / linked in Andrew Ross Sorkin's Dealbook (The New York Times, 2/19/2026)https://www.nytimes.com/2026/02/19/business/dealbook/markets-oil-iran.htmlU.S. Imports Grew in 2025, as Trump’s Tariffs Reshuffled Global Trade (The New York Times, 2/19/2026)https://www.nytimes.com/2026/02/19/business/economy/imports-tariffs-trade-deficit.html

CJEB’s JMLP Program Co-Founder, Yumiko Shimabukuro, Co-Authored Book: Misery Beneath the Miracle in East Asia

Dr. Yumiko Shimabukuro, Faculty, School of International and Public Affairs, Columbia University; Co-Founder, Japanese Management Leadership, co-authored a book titled Misery Beneath the Miracle in East Asia, published by Cornell University Press.“Misery Beneath the Miracle in East Asia challenges prevailing views of the East Asian economic miracle. Existing scholarship has overlooked the severity, persistence, and harmful consequences of the region’s social welfare crises. Arvid J. Lukauskas and Yumiko Shimabukuro fill this gap and put a major asterisk on East Asia's economic record.  Combining big-picture analysis, abundant data, a dynamic interdisciplinary framework, and powerful human stories, they shed light on the social ills that governments have failed to address adequately, including low wages, child abuse, elderly poverty, and substandard housing. One of the major forces behind the multidimensional welfare crises is the region's productivist welfare strategy, which prioritizes economic growth while abandoning a robust social safety net, leaving the most vulnerable segments of society largely unprotected.  Misery beneath the Miracle in East Asia brings the region into debates over the dangers of seeking growth at all costs that are currently embroiling the United States and other advanced industrialized countries.”The book is available for purchase here.

Preeminent Academic Research Center

The Center on Japanese Economy and Business Has Been the Preeminent Academic Research Center for Over 36 Years. Established at Columbia Business School in 1986 under the direction of its founder, Professor Hugh Patrick, and led currently by its director, Professor David Weinstein, the Center on Japanese Economy and Business (CJEB) promotes knowledge and understanding of Japanese business and economics in an international context. CJEB is a research organization widely recognized for its vigorous research activities, international symposia, conferences, and lectures, held in New York City and Tokyo, and most recently online, which provide prominent speakers from the public and private sectors a forum for collaboration and reflection on Japan, the United States, and the global economy.

Under the leadership of Professors David Weinstein and Takatoshi Ito, CJEB’s associate director of research, CJEB supports research projects and library and computer-based resource initiatives. Other core faculty members are Japan specialists drawn from Columbia’s Business School, School of International and Public Affairs, Department of Economics, and Department of Political Science. While CJEB is an independent and nonpartisan research center that takes an objective stance on political or economic policies, we encourage our researchers and scholars to hold their own individual perspectives. Funding and resources are provided by corporate sponsors, foundations, individuals, Columbia Business School, and Columbia University.
