The analysis presented here is an effort to elaborate the patron-client model of association, developed largely by anthropologists, and to demonstrate its applicability to political action in Southeast Asia. Inasmuch as patron-client structures are not unique to Southeast Asia but are much in evidence, particularly in Latin America, in Africa, and in less developed portions of Europe, the analysis may possibly have more general value for understanding politics in preindustrial societies. After defining the nature of patron-client ties and distinguishing them from other social ties, the paper discriminates among patron-client ties to establish the most important dimensions of variation, examines both the survival and transformations in patron-client links in Southeast Asia since colonialism and the impact of major social changes such as the growth of markets, the expanded role of the state, and the creation of local regimes. Finally, the paper shows how patron-client bonds interact with electoral politics to create distributive pressures which, in turn, often lead to inflationary fiscal policies and vulnerability of regimes to losses of revenue.
