The exchange of price-related information between horizontally aligned competitors is often a no-no in the US.
“U.S. Poultry Producers Face Scrutiny,” The Wall Street Journal, December 12, 2016 B2. The Georgia Department of Agriculture compiles a price index based on input from chicken sellers, but not chicken buyers. This index is then used in establishing the prices paid by some buyers.
Is the government facilitating price fixing? For the chicken sellers, is it risky to share price information with anybody other than the buyer? Is this exchange contrary to company policy? Did the lawyers approve?
