The Mythical Causes of the Republican Supply-Side Economics Revolution

In this paper we analyze the two conventional explanations of the Republican Party's adoption of supply-side economic philosophy in the 1977-81 period: first, that the position change was induced by the Sunbelt component of the party; and second, that the doctrinal shift was brought about by widespread concern with tax policy among the public and the Republican mass in particular. We reveal both arguments to be flawed and suggest that the party's advocation of large across-the-board tax cuts was the result of calculated and coordinated decisions by Washington elites within the party. We provide empirical and theoretical justification for a national elite-led explanation of this event. As a result, our study helps solidify contemporary scholarship that counteracts conventional wisdom in comparative politics and suggests that national American parties, at least when it comes to policy formation, can be relatively hierarchical institutions that shape as much as respond to mass and local behavior.
