This paper deals with two issues. By linking culture and political systems, alternatives to the Developmental State approach are developed and the Bureaucratic State, among other types, is proposed for explaining the case of Japan. The Laffont-Tirole (L-T) model of regulatory capture is extended and a bureaucratic capture model is proposed. Variations of capture are shown to apply, given particular cultural predispositions. The case of atomic energy in Japan and the United States is then studied to assess the predictive efficacy of the extended L-T model. The paper concludes that cultural predispositions and the corresponding state types affect the degree to which capture takes place.
