A Ricardo-Sraffa Paradigm Comparing Gains from Trade in Inputs and Finished Goods

Paul Samuelson

Journal of Economic Literature, 2001, vol. 39, issue 4, 1204-1214

Abstract: Here is how the 1817 Ricardo comparative advantage trade benefit analysis has to be modified to take account of post-1960 Sraffian benefits from capital-using technologies. By bringing J. S. Mill's demand model up to date in terms of its implicit geometric-mean money-metric utility, specific measurements for real net national product are calculated to partition sources of welfare gains (from output enhancements and taste-preference accommodations) in scenarios of (1) trade between equals, (2) trade between poor and rich nations, and (3) for biased inventions that enable a poor country to take over production of items in which formerly the rich place enjoyed comparative advantage. History of economic doctrine is mined to advance today's frontier of scientific knowledge--a forward-looking function for "Whig history."
