Many economists and antitrust experts claim that ocean shipping confer
ences are essentially legalized cartels. They often advocate eliminati
ng ocean shipping conferences' antitrust immunity. This paper argues t
hat conferences also help to coordinate their members' joint investmen
ts and thereby allow the historically small firms in this industry to
exploit vast network economies (akin to those in other transportation
industries) that small firms could not capture on their own. The paper
proposes reducing rather than eliminating immunity and calls for an e
nd to many of the regulations currently stifling the industry.
