GRID PRICING VERSUS AVERAGE PRICING FOR SLAUGHTER CATTLE: AN EMPIRICAL ANALYSIS

The paper compares weekly producer revenue under grid pricing and average dressed weight pricing methods for 2560 cattle over a period of 102 weeks. Regression analysis is applied to identify factors affecting the revenue differential.Livestock Production/Industries,

Public Reporting of Fed Cattle Grid Prices: Policy Reform Consequences

Mandatory livestock price reporting was implemented in April 2001. Empirical evidence indicates a significant change in volatility occurred in publicly reported fed cattle grid premiums and discounts after its implementation. Empirical analysis of grid premiums and discounts across the pre-and post-reform periods indicates that increased transparency is compatible with either an increase or a decrease in price volatility in the post-MPR period. Furthermore, it appears that the public price reporting system for weekly grid premiums and discounts failed to provide an adequate level of transparency prior to the implementation of price reporting reforms. Our methodology extends the literature on the use of volatility measures for investigating issues associated with market transparency. This extension can be applied to the development of volatility measures for monitoring the price reporting behavior of firms.cattle pricing, grid pricing, farm policy

Carcass Quality Volume and Grid Pricing: An Investigation of Cause and Effect

The relationship between publicly reported weekly grid premiums and discounts for specific carcass characteristics and the percentage of those characteristics reflected in total weekly slaughter volume (i.e., proportional slaughter volume) is investigated. Granger Causality and multi-lag VAR models were used to investigate if grid premiums and discounts were efficiently transmitting market signals to producers with respect to carcass quality attributes. The empirical evidence indicates that there is little evidence to suggest that grid prices are providing efficient price signals to buyers and sellers with respect to market valuation of desirable and undesirable beef carcass characteristics.grid pricing, price discovery, price reporting, slaughter cattle

GRID PRICING FOR FED CATTLE: AN EMPIRICAL ANALYSIS

Weekly grid premium and discount price date for fed cattle have been collected over a 3-year period. The grid price data are combined with carcass data (2590 South Dakota slaughter steers) to investigate the variability in the average weekly carcass premium is affected by changes in packer-determined grid premiums and discounts on a weekly basis. The three-stage recursive model is then estimated using an autoregressive procedure. The results of the empirical analysis indicated that among all grid premiums and discounts, it is the choice-select discount that plays the dominant role in determining weekly changes in the average weekly carcass premium (discount).slaughter cattle, grid pricing, average pricing, value-based-marketing, Marketing,

Price Transparency in the Voluntary Price Reporting System for Live Cattle: Theory and Empirical Evidence

Interregional spatial linkages between South Dakota and Nebraska cash markets for slaughter cattle are investigated. Econometric procedures are used to test whether a thinning market effect or strategic price reporting behavior by packers has degraded market transparency under the voluntary price reporting system. Empirical evidence suggests transparency was not degraded.Demand and Price Analysis,

Side-slipping of a radiating particle

Radiation reaction is revisited, first in a new classical aproach, where the physical particle 4-momentum is redefined as the energy-momentum flux across the future light cone and is not parallel to the 4-velocity. Then in a semi-classical approach, it is shown that, when emitting a photon, the particle "side-slips" transversaly to its initial momentum, justifying the non-colinearity between momentum and mean velocity. Side-slipping is finally checked in a pure quantum mechanical treatment of synchrotron radiation.Comment: 8 pages, 6 figures. presented at the Int. Conf.

Grid Marketing and Beef Carcass Quality: A Discussion of Issues and Trends

Beef industry data suggest that improvements in carcass yield and quality grades have stagnated recently. Empirical analysis, based on USDA market reports, indicates that the share of steer slaughter volume marketed on a grid is less than industry estimates and the growth in market share has stagnated. Trend analysis of market share suggests that grid pricing has become an important marketing channel, but has not become the dominant marketing channel. The lack of industry progress toward achieving the carcass quality goals suggests that grid pricing has not captured the level of market share needed to realize the goals envisioned for it as a value based marketing system.cattle pricing, grid pricing, farm policy

NAFTA INTRA INDUSTRY TRADE IN AGRICULTURAL FOOD PRODUCTS

The paper focuses on NAFTA's impact on intra-industry and inter-industry trade in agricultural food products. Bilateral trade among U.S., Canada, and Mexico, as well as their trade with the rest of the world during 1990 and 1995 are investigated. U.S. trade patterns for agricultural food products are slowly changing.International Relations/Trade,

SEGREGATING TRANSGENIC GRAINS: RESULTS OF A SURVEY AMONG COUNTRY ELEVATORS IN SOUTH DAKOTA

Using responses from a mail survey conducted among 203 South Dakota grain elevator managers in 2002, we analyzed the degree to which the elevators were prepared to segregate non-transgenic from commodity grains. Only 17 and two percent reported having buyers inquire about segregated non-transgenic or identity preserved corn, and such soybeans, respectively. Among those handling corn (soybeans), 53 (58) percent were willing to participate in non-transgenic corn (soybean) markets at an average premium of 28 (37) cents per bushel. It appears that one in five elevators are able to participate in segregating non-transgenic and commodity grains without additional capital outlays.Crop Production/Industries, Research and Development/Tech Change/Emerging Technologies,
