The cyclical nature of numbers and prices of sheep and lambs was examined from 1924 through 1993. Tests for structural change also were conducted utilizing the minimization of Akaike's information criterion (MAIC). Results indicate that cyclical length in both stock sheep numbers and lamb prices has decreased over time, with a current 10- and 27-year cycle in stock sheep numbers and nine- and 27-year cycle lamb prices. Structural changes occurred in 1951 and 1968 for stock sheep number and in 1952 and 1972 for lamb prices.

A laboratory experimental auction was used to determine factors influencing the relative value consumers place on alternative retail beef packaging. Results indicate information is very important for the successful introduction and marketing of the vacuum skin package. Physical appearance of the beef plays a major role in purchasing decisions by consumers, with fat and shape significantly decreasing the value of beef in the vacuum skin package relative to beef in the overwrapped styrofoam tray package. Experimental economics procedures, when combined with traditional marketing research techniques, can provide useful information for marketing decisions and economic analyses.
