A test of the revealed-preference phenomenon in congressional elections

This study tests for the existence of a revealed-preference phenomenon in recent congressional elections. A revealed-preference analysis predicts that if candidate one defeats incumbent candidate two, then candidate one has been revealed preferred to candidate two, and can expect to secure higher pluralities in subsequent reelection contests than candidate two would have expected. I collect data on incumbents in 1946–1980 congressional elections to examine this prediction. The data provide qualified support for the presence of a revealed-preference phenomenon. The essay closes with a discussion of the possible connection between the revealed-preference phenomenon and the recent electoral experience of congressional incumbents.
