Policy Diversity and Policy Learning in a Federation: The Case of Australian State Betting Law

A case study of the evolution of gambling laws in Australiais the vehicle for an analysis of changing patterns of diversityand uniformity in state policies. A pattern of diverse responsesto the gambling problem in 1930–1960 is explained as theexpression of distinctive state political and other factors.In accounting for the rapid adoption from 1960 of a uniformpolicy in each of the states, explanations are sought both inthe changing nature of these differences and in the interactiveeffects of membership in a federal polity. Particular attentionis paid to the role of "policy learning" among the states andto the "domino effect" of state-by-state adoptions. It is concludedthat such "federal effects" can account for diversity givingway to uniformity in outputs, and that this uniformity doesnot imply a rejection of underlying rationales for federalism.
