Studie zweier Wissenschaftler der Princeton- und Northwestern University zum politischen Einfluss gesellschaftlicher Eliten in den USA, 9.4.2014 (engl. Originalfassung)
Each of four theoretical traditions in the study of American politics – which can be characterized as theories of Majoritarian Electoral Democracy, Economic Elite Domination, and two types of interest group pluralism, Majoritarian Pluralism and Biased Pluralism – offers different predictions about which sets of actors have how much influence over public policy: average citizens; economic elites; and organized interest groups, mass-based or business-oriented.
A great deal of empirical research speaks to the policy influence of one or another set of actors, but until recently it has not been possible to test these contrasting theoretical predictions against each other within a single statistical model. This paper reports on an effort to do so, using a unique data set that includes measures of the key variables for 1,779 policy issues.
Multivariate analysis indicates that economic elites and organized groups representing business interests have substantial independent impacts on U.S. government policy, while average citizens and mass-based interest groups have little or no independent influence. The results provide substantial support for theories of Economic Elite Domination and for theories of Biased Pluralism, but not for theories of Majoritarian Electoral Democracy or Majoritarian Pluralism.
Who governs? Who really rules? To what extent is the broad body of U.S. citizens sovereign, semi-sovereign, or largely powerless? These questions have animated much important work in the study of American politics.
While this body of research is rich and variegated, it can loosely be divided into four families of theories: Majoritarian Electoral Democracy, Economic Elite Domination, and two types of interest group pluralism – Majoritarian Pluralism, in which the interests of all citizens are more or less equally represented, and Biased Pluralism, in which corporations, business associations, and professional groups predominate) Each of these perspectives makes different predictions about the independent influence upon U.S. policy making of four sets of actors: the Average Citizen or “median voter,” Economic Elites, and Mass-based or Business-oriented Interest Groups or industries.
Each of these theoretical traditions has given rise to a large body of literature. Each is supported by a great deal of empirical evidence – some of it quantitative, some historical, some observational – concerning the importance of various sets of actors (or, all too often, a single set of actors) in U.S. policy making. This literature has made important contributions to our understanding of how American politics works and has helped illuminate how democratic or undemocratic (in various senses) our policy making process actually is. Until very recently, however, it has been impossible to test the differing predictions of these theories against each other within a single statistical model that permits one to analyze the independent effects of each set of actors upon policy outcomes.
Here – in a tentative and preliminary way – we offer such test, bringing a unique data set to bear on the problem. Our measures are far from perfect, but we hope that this first step will help inspire further research into what we see as some of the most fundamental questions about American politics.
The central point that emerges from our research is that economic elites and organized groups representing business interests have substantial independent impacts on U.S. government policy, while mass-based interest groups and average citizens have little or no independent influence. Our results provide substantial support for theories of Economic Elite Domination and for theories of Biased Pluralism, but not for theories of Majoritarian Electoral Democracy or Majoritarian Pluralism.
In what follows, we briefly review the four theoretical traditions that form the framework for our analyses and highlight some of the most prominent empirical research associated with each. We then describe our data and measures and present our results. We conclude by discussing the implications of our work for understanding American democracy and by identifying some of the directions for future research that our findings suggest.
