The rational behavior theory of voting participation: Evidence from the 1970 and 1982 elections

In recent years a substantial literature on the determinants of voting participation has been developed. In many of these studies voting is assumed to be an expression of rational behavior. That is, people vote when they expect that the benefits will exceed the related costs. Voting is largely an act of consumption based upon the widely held belief that one should vote to fulfill a civic duty or upon some combination of personal characteristics which is sufficiently vague to make precise measurement impossible. The rational behavior theory, however, holds that voting is influenced at the margin by personal and environmental factors which incrementally affect expected benefits and costs, making the act of voting more or less rational. Those factors which increase expected benefits will, ceteris paribus, enhance the probability that one will vote. Those factors which increase expected costs will, of course, have the opposite effect. This study is presented as a primarily empirical contribution to the literature which assumes that, since voting is an expression of rational behavior, it can be modeled and tested using standard economic analysis and methodology. The study is designed to fulfill several purposes. First, we update previous empirical work using data from the 1980 census and from the 1982 congressional elections. The results of our regressions strongly support the rational behavior theory. In addition, we test to determine whether it is less rational for southern blacks to vote as compared to their white counterparts. Our results suggest that the answer is affirmative. Tests of parameter equivalency between the 1970 and 1982 congressional elections are performed with some interesting results. Finally, tests for specification error provide evidence that the rational behavior model and congressional district data generate statistically valid estimates of the determinants of voting participation.
