The Nobel Prize Committee explains Krugman's contributions in Trade and Geography – Economies of Scale, Differentiated Products and Transport Costs

Since the explanation all has to do with the phenomenon of the effect of increasing returns to scale on trade, I am not sure what you think is Marxist about it.

Ah, Andy m'friend. Read that wonderful little paper. You'll see, straightaway. I'll give you a hint: guess what Krugboy suggests as a remedy when geography ''interferes'' with what he describes as ''normal patterns of trade''.

Three guesses. First two don't count.

Have fun, laddy!
