Two approaches have been taken to the modeling of poultry demand in U.S. me
at demand studies. One has been to ignore turkey, and estimate demands for
beef, pork, and chicken. The second has been to include turkey by combining
it with chicken, and estimating demands for beef, pork, and poultry. The v
alidity of these two approaches is examined using quarterly U.S. time-serie
s data from 1980-96. The results indicate that either approach to the model
ing of poultry demand is appropriate.
