Several quantitative methods have been developed to evaluate the Impacts of technological change on U.S. agriculture. The major weakness of prevailing models is that they consider the impact of technology on supply alone and are based on partial equilibrium analysis in one market. The use of...

This paper examines the impact that publicly funded agricultural research has on productivity in crop production within Thailand. It tests empirically the two hypotheses that, first, publicly funded research and development (R&D) in crop production is a significant determinant of total factor...

Prices of basic food staples and feed crops have soared in recent years, renewing concerns about the ability of global food supplies to meet the projected growth in aggregate demand. Notwithstanding these concerns, and apparently at odds with a vast body of economic evidence reporting...

Recent trends in farm productivity and food prices raise concerns about whether the era of global agricultural abundance is over. Agricultural R&D is a crucial determinant of agricultural productivity and production, and therefore food prices and poverty. In this paper we review past and present...

Proper stationarity assumptions (trend stationarity or difference stationarity)are important for modeling agricultural supply response in the context of time series analysis Test reults show that the assumption of trend stationarity should be a tested rather than a maintained hypothesis We...

The conservation compliance provision of the 1985 Food Security Act requires farmer to implement conservation plans on highly erodible croplan as a prerequisite for elegibility in agricultural commodity programs Reducing erosion to the soil loss tolerance level on about 46 million highly...
