The most telling part of the choice was the formal statement of the Royal Swedish Academy of Sciences explaining the choice. It said, in part:
Traditional trade theory assumes that countries are different and explains why some countries export agricultural products whereas others export industrial goods. The new theory clarifies why worldwide trade is in fact dominated by countries which not only have similar conditions, but also trade in similar products – for instance, a country such as Sweden that both exports and imports cars.So, the ladies and gentlemen of the Prize Committee who must have been locked up incommunicado in the basement of Ricardo household since the 18th century think that everyone thinks that Japanese are supposed to export rice; Americans, car; Germans, beer and French, cheese. Naturally, Krugman who has “shown” that they all could and do export cars is an outstanding economic mind.
