by From Lars Syll Plenty of people will try to convince you that globalization and free trade could benefit everyone, if only the gains were more fairly shared … This belief is shared by almost all politicians … and it’s an article of faith for the economics profession. You are right to reject it … It’s a fallacy based on a fantasy, and it has been ever since David Ricardo dreamed up the idea of “Comparative Advantage and the Gains from Trade” two centuries ago. The best way to prove that is to apply real-world scepticism to the original argument in favour of free trade … Ricardo’s model assumed that you could produce wine or cloth with only labour, but of course you can’t. You need machines as well, and machinery is specific to each industry. The essential machinery for making wine can’t be used to make anything else, if its use becomes unprofitable. It is either scrapped, sold at a large loss, or shipped overseas. Ditto a spinning jenny, or a steel mill: if making steel becomes unprofitable, the capital involved in its production is effectively destroyed … Ricardo’s little shell and pea trick is therefore like most conventional economic theory: it’s neat, plausible, and wrong. It’s the product of armchair thinking by people who never put foot in the factories that their economic theories turned into rust buckets.

As always with Keen — thought-provoking and interesting. But I think he misses the most powerful argument against the Ricardian paradigm — what counts to day is not comparative advantage, but absolute advantage. 
What has changed since Ricardo’s days is that the assumption of internationally immobile factors of production has been made totally untenable in our globalised world. When our modern corporations maximize their profits they do it by moving capital and technologies to where it is cheapest to produce. So we’re actually in a situation today where absolute — not comparative — advantages rules the roost when it comes to free trade.
And in that world, what is good for corporations is not necessarily good for nations.
