文章针对花旗研究（Citrini Research）关于人工智能将引发经济崩溃的流行观点提出了质疑，指出其逻辑在经济学原理上存在缺陷。该文分析了所谓“幽灵GDP”的预言，即AI虽然创造了巨大产出，但因失业导致消费能力消失，从而引发生产过剩的危机。作者通过引用古典经济学中的赛伊定律以及凯恩斯的理论，阐明生产本身即创造需求，且政府拥有多种调节工具来应对可能的需求疲软。最终，文章强调当前的AI企业更倾向于重新投入资本而非积压现金，因此那种产出激增而需求枯竭的极端预测在现实中极难成立。
The Citrini effect
A viral research note on AI gets its economics wrong

AS STOCKS WOBBLED in the last week of February, some found a cause in a note by Citrini Research, a firm of equity analysts. It imagined a world in 2028 in which artificial intelligence had rendered a lot of white-collar work obsolete—along with firms from American Express to DoorDash and much of the software industry. The note went viral. But its economics are shaky.
▶ 中文翻译：
在2月最后一周股市波动之际，一些人将原因归咎于股票分析公司Citrini Research发布的一份报告。该报告设想了2028年的世界，届时人工智能将淘汰大量白领工作——以及从美国运通（American Express）到DoorDash等公司以及大部分软件行业。这份报告迅速传播开来，但其经济学分析却站不住脚。
▶ 英文段落：
In Citrini’s near future, output keeps growing, “driven by AI agents that don’t sleep, take sick days or require health insurance”, while consumer spending collapses: workers have no jobs and no incomes to spend. “Economic pundits popularised the phrase ‘Ghost GDP’: output that shows up in the national accounts but never circulates through the real economy.”
▶ 中文翻译：
在Citrini设想的近期未来，产出持续增长，“由不睡觉、不请病假也不需要健康保险的AI代理驱动”，而消费支出却崩溃了：工人没有工作，也没有收入可供消费。“经济专家们普及了‘幽灵GDP’这一说法：即出现在国民账户中，但从未在实体经济中流通的产出。”
▶ 英文段落：
Economists have been here before. In the early 19th century David Ricardo, a financier, and Thomas Malthus, a clergyman, debated the possibility of a “general glut”. Grain prices were falling and industrial output surging, but workers were visibly unemployed. A surge in output was seemingly matched by an absence of spending power. There was too much of everything all at once.
▶ 中文翻译：
经济学家们以前也曾遇到过类似情况。19世纪早期，金融家大卫·李嘉图（David Ricardo）和神职人员托马斯·马尔萨斯（Thomas Malthus）曾争论“普遍过剩”的可能性。当时粮价下跌，工业产出激增，但工人却明显失业。产出的激增似乎与购买力的缺失相伴。一切都一下子变得太多了。
▶ 英文段落：
Ricardo thought such a thing impossible. It violated Say’s Law, that “production creates its own demand”. How does a farmer buy textiles? He produces food and swaps it: real output is the income with which to buy something else. Only a “partial glut” was possible. One sector (say software today) might produce so much that its prices collapse and its workers lose jobs, but that should allow another to purchase more. Some people and firms lose and others win, but that is the nature of economic disruption.
▶ 中文翻译：
李嘉图认为这样的事情是不可能的。这违反了萨伊定律，即“生产创造其自身的D需求”。农民如何购买纺织品？他生产食物并交换它：实际产出是购买其他商品的收入。只有“局部过剩”是可能的。一个部门（比如今天的软件业）可能生产过剩，导致其价格暴跌，工人失业，但这应该能让另一个部门购买更多。有些人或公司受损，另一些人或公司获益，但这正是经济颠覆的本质。
▶ 英文段落：
Yet economy-wide recessions do happen. Later economists, such as John Maynard Keynes, pointed out that money could get in the way. Production and consumption do not have to be simultaneous: a firm can make something, sell it and then hold on to the cash. A general glut was therefore possible. Perhaps this time the owners of AI companies will simply sit on the cash their bots generate. But that would be deflationary, rather than lead to the surge in nominal GDP Citrini predicts. Unemployment would indeed rise, but GDP would fall.
▶ 中文翻译：
然而，全经济范围的衰退确实会发生。后来的经济学家，如约翰·梅纳德·凯恩斯（John Maynard Keynes），指出货币可能会从中作梗。生产和消费不必同时进行：一家公司可以生产某物，出售它，然后持有现金。因此，普遍过剩是可能的。或许这次人工智能公司的所有者会简单地坐拥他们的机器人所产生的现金。但这将是通货紧缩性的，而非导致Citrini预测的名义GDP飙升。失业率确实会上升，但GDP会下降。
▶ 英文段落：
Is this a plausible future? It doesn’t look that way. If anything AI companies are desperate to redeploy cash to build more data centres, not to hoard it, even though big productivity gains· are elusive so far. Many investors worry that AI companies will run out of funding. And policymakers have tools of stimulus—interest-rate cuts, bond-buying and handouts—with which to fight demand slumps. It is unlikely that an AI take-off would bring about an economy that lacks spending.
▶ 中文翻译：
这是一个可能实现的未来吗？似乎并非如此。如果说有什么的话，人工智能公司正迫切地希望重新部署现金以建设更多数据中心，而不是囤积现金，尽管迄今为止大规模的生产力提升仍难以捉摸。许多投资者担心人工智能公司会耗尽资金。而且政策制定者拥有刺激工具——降息、购买债券和发放补贴——可以用来对抗需求低迷。人工智能的腾飞不太可能导致一个缺乏消费的经济。
