ABSTRACT
In the classical model of economic development, population growth was believed to be dependent on the quality of agricultural resources. The induced innovation perspective directs attention both to conditions under which the growth of population induces agricultural productivity growth and under which resource endowments, which act as a constraint on growth of productivity in rural areas, are released by advances in technology. It seems clear that the dominant effects of biased technical change in US agriculture on the production structure were labor-saving and power-using throughout the entire period of analysis. Until the end of the 1950s, Philippine agriculture followed the traditional vent-for-surplus pattern of agricultural development characteristic of much of Southeast Asia. The epochal change in the agricultural growth momentum in the Philippines between the 1950s and the 1960s is clearly reflected in the spurt in rice yield per hectare in the 1960s.
