Regulators often impose price floors to protect producers from suspected oligopsony power. However, if price floors are set too high, traded quantities and market efficiency fall. We study the threshold from which price floors are set too high in markets with intermediaries. A theoretical model...

This is a survey of the economic principles that underlie antitrust law and how those principles relate to competition policy. We address four core subject areas: market power, collusion, mergers between competitors, and monopolization. In each area, we select the most relevant portions of...
