The conceptualization of political and economic determinants of public policy as interactive rather than sufficient causes is subjected here to a comparative state analysis. An examination of interactive effects of culture, wealth, and gubernatorial power on AFDC grants and Medicaid benefits offers empirical illustration of Stonecash's reconceptualization of the classic politics-process-policy model. The results indicate that political dispositions become more potent in combination with increasing concentrations of wealth and executive power.
