Tornquist input quantity indexes derived from USDA/SRS/FEDS survey data along with yield data are used to derive total and partial factor productivity measures across time and region for a sample of representative u.s. cotton enterprises. Total factor productivity for u.s. cotton increased only...

The purpose of this paper is to estimate the cost structures and resource productivities involved in production of four major U.S. field crops and to estimate the distribution among producers of benefits from production related technology. These field crops include corn, soybeans, wheat and...

Tornquist input quantity indices were used to derive total and partial factor productivity measures for U.S. cotton across time, region, and scale. Total factor productivity for U.S. cotton increased .2 percent per year between 1974 and 1982. Partial productivity measures revealed that yield...

Between 1974 and 1983, intertemporal cost efficiency for u.s. field crops increased about 1.4 to 1.2% percent for corn, soybeans, and wheat and .2% per year for cotton. competitive advantage in 1983 was held by central Illinois and north central Iowa in corn, central Illinois in soybeans, the...

The total factor productivity index for u.s. wheat was 1.5% per year between 1974 and 1983. The conservation tillage productivity index for u.s. wheat was about 1.1% per year during this time period, or about 75% of the T.F.P. North Dakota and Washington were equal in competitive advantage in...
