Public policy by the principal developed country (DC) governments since about 1979 has accepted, and probably caused, this interest upsurge. These governments, reacting against and inappropriately Keynesian response to the first (1973) oil price shock, decided to squeeze out inflation (and inflationary expectations) after the second (1978) shock. Around 1978-1984, this squeeze was attempted mainly by restraining the growth of the money supply, which led to increases in the nominal rate of interest. At the same time, the United States public sector deficits (and perhaps those in some other developed countries) added market-based upward pressure on interest rates. Rates charged by leading public institutions to borrowing governments – even on old loans – since the late 1970s have responded quickly to market conditions. There is no reason to doubt that these changes are passed on to final borrowers, especially in view of pressures by donors upon developing country governments to phase out interest rate subsidies.

Exogenous Technical Progress

In the long run, at least in the more vibrant regions of developing country farming technology probably affects farm-level incentives more than prices do. For example, the productivity levels of land, labor, fertilizer, and irrigation in rice or wheat production in the Indian Punjab have probably changed faster over the 1964-1992 period than their respective input/output price ratios. Farmers’ selection from an available set of generated production technologies determines whether their response to the joint pressures of population and changing prices will be resource-enhancing or resource-degrading.
