The concept of political clientelism is one if the few genuinely crosscultural concepts available to political scientists for the comparative study of transitional systems. As a descriptive concept, political clientelism helps us uncover patterns of relationships which deviate markedly from those ordinarily associated with class or ethnicity. As an analytic concept political clientelism provides crucial insights into the internal dynamics of social and political change. Moreover, if, as some contend, patterns of resource allocation are more meaningful indicators of political development than their conceptual opposites, political clientelism may well supply the critical “missing link” between micro- and macro-sociological or system-centered theories of political development.
