David Ricardo Quotes

“Economists have always been haunted by the spectre of ‘diminishing returns’. Ricardo had famously seen ‘diminishing returns’ in agriculture leading to a progressive fall in the rate of profit, a progressive shift of the terms of trade between manufacturing and agriculture in favour of the latter and the eventual denouement of a stationary state where further growth became impossible. Even Keynes in the aforementioned work saw ‘diminishing returns’ in food production as undermining the Eldorado even if the war had not done so. And yet none of these fears have come true. The terms of trade between manufacturing and agriculture have shown a secular tendency to shift against, rather than in favour of, the latter; and while the growth rate under capitalism has come down of late, this has nothing to do with any fall in the profit rate caused by ‘diminishing returns’. Likewise, the advanced capitalist world has no difficulty to this day in meeting its food requirements, belying the fears of Keynes. How then do we explain this contrast between fears and reality?”
