Economist at George Mason University, co-author of Marginal Revolution, host of Conversations with Tyler. Writes in short, dense claims about economics, culture and AI, and has moved his position on AI in public more than once.

Tyler Cowen did not write this page.

We collected these quotes from things they published elsewhere, and every quote links to where it was said. They have no account here and have not endorsed this site. Quotes are word for word; the short line under each one is our own restatement, not their wording. Their own site. Is this you? Claim it or ask us to remove it. Or tell us what is wrong here.

Five ideas Tyler Cowen's claims keep coming back to. The grouping and the labels are ours; every quote under them is in Tyler Cowen's own words.

  1. AI mostly complements human knowledge, and the strongest fears about it look overstated
  2. AI policy has to start with China, and regulation that ignores it deserves suspicion
  3. Economics is messier than its simple models, so macro and policy certainty deserve skepticism
  4. Successful societies solve problems bit by bit, and pessimism about them often outruns the record
  5. Great economists are shaped by temperament and place, and Mill and Hayek hold up unusually well

AI mostly complements human knowledge, and the strongest fears about it look overstated

Our label. 10 claims in Tyler Cowen's own words.

The core prediction is that a huge positive shock to AI-boosted Intelligence increases marginal returns, employment, and real wages in the Polanyi (tacit) knowledge sector.

  1. Tyler Cowen Economist at George Mason University Now recently the U.S. economy has experienced a huge positive shock to its Intelligence, with more to come. The core prediction is that this increases marginal returns, employment, and real wages in the Polanyi knowledge sector.

In a simple model of AI-aided growth, intelligence and Polanyi knowledge are mostly complements, with fairly limited substitutability in producing output.

  1. Tyler Cowen Economist at George Mason University In the model, intelligence and Polanyi knowledge combine to produce output. Substitutability is fairly limited. For instance, if you have problems of norms in your office, a mere dose of AI-drenched technocratic knowledge does not usually solve those problems. Sometimes it even can make those problems worse, by empowering rent-seekers further. Intelligence and Polanyi knowledge are not quite Leontief complements, but they are mostly complements.

In this model, commandeering the Intelligence sector would give much more limited power over society than might appear at first, because necessary complements are lacking.

AI policy has to start with China, and regulation that ignores it deserves suspicion

Our label. 6 claims in Tyler Cowen's own words.

AI policy discussions should start with China rather than treating it as an afterthought.

  1. Tyler Cowen Economist at George Mason University Whatever your ideas for regulating AI, I say start with China. Do not put China as an afterthought at the end of your proposal, mentioned in a vague wish that something good ought to happen and that maybe the future of humanity can be secured.

AI regulation proposals that do not address China issues specifically and forthrightly should be treated with suspicion.

  1. Tyler Cowen Economist at George Mason University If you are reading proposals or for that matter tweets for AI regulation, and the writer does not deal with these China issues in a forthright and very specific manner, you should be very suspicious indeed.

A ban on self-recursive improvement in AI models would create a big incentive for some other parts of the world to invest a lot more in compute.

China declined U.S. nuclear-talk proposals in 2023 and broke off meaningful arms control talks.

  1. Tyler Cowen Economist at George Mason University During the 2023 U.S.-China nuclear talks, America proposed missile-launch notifications, a nuclear crisis hotline, and processes to limit the use of outer space for military conflict. China declined all of those. Blame the U.S. if you wish (do we always keep our word?), but that is what happened. China also broke off meaningful arms control talks.

Economics is messier than its simple models, so macro and policy certainty deserve skepticism

Our label. 11 claims in Tyler Cowen's own words.

Milton Friedman's chief intellectual flaw was wanting to make economics too simple.

Neither monetarist money-supply-focused models nor Keynesian macro models have outperformed simple random-walk models at forecasting the macroeconomy.

  1. Tyler Cowen Economist at George Mason University Friedman’s focus on the money supply has not held up, as Samuelson suggested, but the alternative Keynesian macro models recommended by Samuelson in the same interview have not done better and they were not outperforming simple random walk models of predicting the macroeconomic future.
