Design and development criteria for metal bellows

Experimental research describes fluid flow and the fluid-elastic mechanism causing bellows flow excitation, and aids in design of conventional bellows liner which suppresses flow-induced vibrations. Analytical models facilitate prediction of flow excitation occurrence and estimation of severity of bellows vibrations

FED CATTLE SPATIAL TRANSACTIONS PRICE RELATIONSHIPS

Delineation of geographic markets for fed cattle is essential in monitoring price behavior and determining geographic markets. This study uses transactions data from 28 U.S. fed cattle slaughter plants to determine the extent of the geographic market for fed cattle. Results indicate a national market for fed cattle with prices across most plants cointegrated. In addition, price discovery originates predominantly at plants located in Nebraska, and typically one-third of the total price adjustment to spatial integration occurs in one day.Cointegration, Relevant market, Spatial prices, Demand and Price Analysis, Livestock Production/Industries,

DETERMINANTS OF FEEDER CATTLE PRICE-WEIGHT SLIDES

Feeder cattle price-weight slides are analyzed using transactions data on 46,123 pens of feeder cattle over a 10-year period. Fed cattle futures prices and corn prices are important determinants of price-weight slides. Cattle producers can use this information when making sell timing decision, purchase decisions, and managing production.Livestock Production/Industries,

HEDGING WHOLESALE BEEF CUTS

Live cattle futures markets do not offer much opportunity for effective hedging of wholesale beef cuts. If a Choice-to-Select price spread futures contract were introduced this would enhance hedging effectiveness although likely not enough to encourage cross hedging. If a Choice boxed beef futures contract were introduced, hedging Choice wholesale beef cuts would be less risky and the addition of a Choice-to-Select price spread would enhance hedging effectiveness especially for Select wholesale beef cuts.Livestock Production/Industries, Marketing,

Price Dynamics in International Wheat Markets

Vector autoregressions are used to evaluate dynamic relationships among prices in six important international wheat markets. The effects of freight rates and exchange rates are also considered. The results indicate that Canada is the dominant market, supporting views that Canada is an oligopolistic price leader.international trade, vector autoregressions, wheat markets, International Relations/Trade,

Determinants of Beef and Pork Brand Equity

A set of consumer-level characteristic demand models were estimated to determine the level of brand equity for pork and beef meat cuts. Results indicate that brand premiums and discounts vary by private, national, and store brands; and brand equity varies across meat cuts carrying the same brand name. Other results are that product size discounts are linear, meat items on sale are significantly discounted to non-sale items, specialty stores typically do not garner higher prices than supermarket/grocery store, and warehouse/super center stores typically premium price to supermarket/ grocery store.Demand and Price Analysis,
