FACTORS AFFECTING WHEAT PROTEIN PREMIUMS

This study used Rosen's methodology of deriving a marginal implicit price series from traditional hedonic modeling and then using this series to estimate a demand model. This procedure was applied to Kansas Hard Red Winter wheat protein. Results were mixed. Own-district protein level was not economically significant; however, an increase in other Kansas district's protein level and the North Dakota Hard Red Spring protein level may have a slight economic impact on own-district protein premium. The results of this study indicate that new varieties of wheat developed that increase protein content without loss of yield and that are regional specific can impact the price or wheat in other areas.Wheat, Characteristic Demand Model, Protein, Crop Production/Industries, Research Methods/ Statistical Methods,

JAPANESE DEMAND FOR WHEAT CHARACTERISTICS: A MARKET SHARE APPROACH

This research took from the work of Kohli and Morey in the economics literature to apply a quality derived market share demand function to the international wheat market. Specifically, a Japanese wheat import demand market share model was derived using data for Hard Red Winter, Hard Red Spring, Canadian Western Red Spring, and Australian Standard White wheat. Results indicate that the four wheat classes analyzed here are relatively good substitutes for each other, the own-price elasticity for each wheat class is elastic, and the own-characteristic Protein elasticity for Hard Red Winter 13% protein wheat increased over the period analyzed.Crop Production/Industries, Marketing,

Factors Affecting Wheat Proteins Premiums

This revision is dated October 2003.This study used the Rosen methodology of deriving a marginal implicit price series of a characteristic from traditional first-stage hedonic modeling and then using this series to estimate a demand model for the characteristic wheat protein. This procedure was applied to Kansas Hard Red Winter and North Dakota Hard Red Spring wheat. Estimated flexibilities indicate an elastic demand for both Hard Red Winter and Hard Red Spring wheat protein. Also, cross-price flexibilities for wheat protein indicate that an increase in the demand for protein in one region has a significant impact on the value of the other regions' wheat crop.Funding for this research was supported by a grant from the National Research Initiative of the United States Department of Agriculture

Are Hedonic Second-Stage Characteristic Demand Reflective of Actual Characteristic Demands?

This revision is dated October 2003.Employing characteristic demand modeling theory to derive input characteristic values, we used these values to estimate characteristic demand models and compare results from this procedure (indirect) to characteristic demand model results using a direct procedure. We model wheat protein because of the extensive previous research on valuing wheat protein and the availability of data to estimate direct protein demand models. Our results indicate concern in using indirect generated data to estimate factors affecting the demand for characteristics. In particular, we find that the magnitude of difference between the direct and indirect estimated flexibilities for wheat protein differs by around a factor of forty.Funding for this research was supported by a grant from the National Research Initiative of the United States Department of Agriculture

Guaranteeing Solar Access in Virginia

The idea of using solar rays as a source of power is certainly not new. History records Archimedes\u27 use of a solar concentrator to burn enemy vessels. The use of solar heat engines for over 150 years, the operation of a massive solar still to convert sea water to potable water in Chile for 40 years, and the development of an elaborate solar furnace in France are noted examples ofthe long standing and highly successful application of solar power

The lives and deaths of positrons in the interstellar medium

We reexamine in detail the various processes undergone by positrons in the ISM from their birth to their annihilation using the most recent results of positron interaction cross sections with H, H2 and He. The positrons' lives are divided into two phases: the 'in-flight' phase and the thermal phase. The first phase is treated with a Monte Carlo simulation that allows us to determine the fraction of positrons that form positronium and annihilate as well as the characteristics of the annihilation emission as a function of the medium conditions. The second phase is treated with a binary reaction rate approach, with cross sections adopted from experimental measurement or theoretical calculations. An extensive search and update of the knowledge of positron processes was thus undertaken. New reaction rates and line widths have been obtained. We investigate the treatment of the complicated interactions between positrons and interstellar dust grains. New reaction rates and widths of the line resulting from the annihilation inside and outside of the grain have been obtained. The final results of our calculations showed that dust is only important in the hot phase of the ISM, where it dominates all other processes. Combining the new calculations, we have constructed annihilation spectra for each phase of the ISM, considering various grain contents, as well as an overall combined spectrum for the ISM as a whole.Comment: 16 pages, 6 figures. accepted in Astronomy and Astrophysic
