Abstract: Haltiwanger and Harrington (1991) reveal that, while the gain from deviating from a collusive agreement in an oligopolistic industry is greatest during booms, it is most difficult to collude during recessions since foregone profits inflicted on defection arc relatively low in recessions. Their numerical simulations show that firms price more counter-cyclically during recessions than during booms to deter relatively greater incentive to defect in recession. This paper tests for a potential asymmetry in the response of margins to the level of demand across booms and slumps, using panel data covering 180 U.S. four-digit level SIC manufacturing industries over the 1963-1987 period. The principal findings accept this theoretical prediction.
