This paper addresses the issue of selecting pricing institutions in a bilateral monopoly. Suppose a buyer and seller can benefit from exchanging one unit of a good. The seller is entitled to select the pricing institution. He can either make a take-it-or-leave-it offer or enter a bargaining game. Under incomplete information, a take-it-or-leave-it offer performs two tasks. When informaion is one-sided incomplete, it prevents the occurrence of a Coase conjecture outcome. When uncertainty is two-sided, it signals the seller's cost in providing the good. Thus, a seller who finds it unprofitable to commit under one-sided incomplete information, may be prepared to do so when the buyer is uncertain about his type. This leads to conclude that pricing institutions are endogeneous with respect to the information available to the trading parties.
