JOSEPH LOEWENBERG AND WILLIAM A. KLEINTOP Although the legislative framework for interest arbitration of municipal-police impasses in Pennsylvania has remained unchanged since 1968, survey data revealed that the rate of negotiations ending in conventional interest arbitration was significantly lower in the second decade than that in the first decade. In testing four hypotheses, the study found some support for the narcotic effect and for larger municipalities being more likely to receive an arbitration award than smaller ones; however, there was no support for arbitration to occur more often where other employees are organized or for arbitration to be invoked more frequently if negotiations take place early in a particular bargaining year.
