Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

As I understand it, we're never supposed to pick comparative advantages that are as potentially unsustainable as some of the financial instruments Mig has referred us to... it's not something the theory seems to consider, but then, IANAE either...

Since, as not-economists (ie dummies), the kind of analogies we are offered by way of explanation of comparative advantage generally concern Bob and Alice who grow tomatoes and lettuces, or some such agricultural object lesson, it's interesting to note that the theory never takes into account that it might be a more sustainable practise to rotate the cultures of tomatoes and lettuces rather than specialise.

This takes on real-world proportions when applied to rain-forest clearance for monocultures. Yet we're still being told, in the name of comparative advantage, that the Doha Round is the way to go.
