Cost and the calculus of voting

Downs's (1957) theory of voting maintains that individuals balance the costs of voting against anticipated benefits in deciding whether to vote. However, most empirical tests of his theory have concluded that costs play little role in individuals' decisions to vote or abstain, and that benefits are the determining factor. Unfortunately, the existing empirical tests of the theory have been inadequate, especially in regard to the measurement of the cost of voting. Using data from the Comparative State Elections Project, we develop an improved indicator of the cost of voting. When this measure of cost is used in a test of Down's theory, we find, contrary to most earlier research, that the cost of voting seems to be a more important determinant of participation than the factors associated with voting benefits in Downs's model.The authors shared equally in the research reported; the order in which they are listed was determined randomly.
