In this study, we explain a half-century of crop yield growth along an 800-mile transect of the forty-first parallel North in the U.S. Great Plains. Using 101 county-level observations from 1960-2008 we jointly estimate a biomass production function with cost shares for fertilizer and chemicals while controlling for environmental factors. The main contributors to yield increases in this region were non-specific technical change +62%, irrigation +17%, fertilizer +13% and chemicals +11%. Environmental changes had a minor impact on regional yield changes. The wide range of agroclimatic conditions present along this transect produced significant sub-regional deviations from the aggregate estimates. While …

Young (1995) estimated Total Factor Productivity (TFP) growth for Hong Kong, Taiwan, Singapore and South Korea. He reported moderate growth rates for these four regions. This means that rapid growth of GDP in these four economies is due mainly to fast increase of inputs. Young (2000) also estimated the TFP growth rate of China to be 1.4% per year during the period of 1978 to 1998. Similar to his claim for the four 'Asian Tigers', he concluded that 'the productivity performance of the non-agricultural economy (of China) during the reform period is respectable, but not outstanding.' China's real GDP grew …
Price-Conditional Technology, Lilyan E. Fulginiti
Price-Conditional Technology, Lilyan E. Fulginiti
Department of Agricultural Economics: Faculty Publications
Economics theorists for years have considered the possibility that the direction of technical change is altered by changes in relative prices. Prices also have been identified as one of the determinants of technical change through innovation, This article extends the theory of the firm to cover situations in which the firms technology set is conditional on expected prices. The basic idea is to distinguish between "market prices," or the prices that guide the firm's choices subject to the technology that is in place, and "normal prices," the prices conditioning the choice of technology. A “generalized" price effect is obtained that …
