So here's the conclusion:
The poultry industry is the only unequivocal winner of the implementation of COOL. We assumed that the poultry industry's cost structure was unaffected by COOL because poultry is currently excluded from COOL legislation. Consequently, increased COOL marketing costs in the beef and pork sectors that increase retail beef and pork prices encourage consumers to substitute towards poultry products. This demand increase causes subsequent increases in poultry prices, quantities, and producer and consumer surplus in the poultry industry.
For authors from Montana State University (Gary Brester, John Marsh, and Joseph Atwood) and magazine editors from Texas A&M university, the conclusion that "the poultry industry benefits at the beef industry's expense" counts as very faint praise for COOL.
