Texas-Oklahoma Producer Cotton Market Summary: 2000/2001 AgEcon
Ward, Jason; Nelson, Jeannie; Misra, Sukant K.; Ethridge, Don E..
The size of the Texas-Oklahoma spot market analyzed by the Daily Price Estimation System (DPES) for the 2000/2001 marketing year decreased considerably from the previous year. The average price received by producers during the 2000/2001 marketing year was about 50.9 cents/lb. The 2000 crop was generally of good quality, but the averages for the first digit of the color grade and leaf grade detoriated as compared with the 1999 crop. The percentage of bales having level 1 and 2 bark, and level 1 and 2 other extraneous matter decreased in comparison to the 1999 crop. With the exception of the second digit of the color grade price discounts for the 2000 crop decreased for all quality attributes. The premiums for the first digit of the color grade and strength...

Texas-Oklahoma Producer Cotton Market Summary: 1999/2000 AgEcon
Nelson, Jeannie; Hoelscher, Kevin; Misra, Sukant K.; Ethridge, Don E..
The size of the Texas-Oklahoma spot market for the 1999/2000 marketing year increased considerably from the previous year and the average producer price declined for the fourth year in a row. The average price received by producers during the 1999/2000 marketing year was about 37.82 cents/lb., which was 13.32 cents/lb. lower than the previous marketing year. The 1999 crop was generally of good quality, but the average for staple length and strength declined compared to the 1998 crop. The percentage of bales having level 2 bark, and level 1 and 2 other extraneous matter also increased marginally when compared to the 1998 crop. With the exception of the first digit of the color grade, level 1 bark, and level 2 other extraneous matter, price discounts for the...

ESTIMATION OF EFFICIENT REGRESSION MODELS FOR APPLIED AGRICULTURAL ECONOMICS RESEARCH AgEcon
Ramirez, Octavio A.; Misra, Sukant K.; Nelson, Jeannie.
This paper proposes and explores the use of a partially adaptive estimation technique to improve the reliability of the inferences made from multiple regression models when the dependent variable is not normally distributed. The relevance of this technique for agricultural economics research is evaluated through Monte Carlo simulation and two mainstream applications: A time-series analysis of agricultural commodity prices and an empirical model of the West Texas cotton basis. It is concluded that, given non-normality, this technique can substantially reduce the magnitude of the standard errors of the slope parameter estimators in relation to OLS, GLS and other least squares based estimation procedures, in practice, allowing for more precise inferences...
