We propose a simple agency framework in which although competing producers always find it optimal to share information about their list (undiscounted) prices, consumers are not necessarily harmed by these agreements. In particular, when sales are delegated to self-interested parties (such as salesmen or retailers), we find that expected discounts are higher with than without information sharing if and only if agency costs are sufficiently low. This shows that agreements according to which firms disclose list prices to their competitors should be presumed neither as anti-competitive nor as pro-competitive.
