Eighteen empirical studies from fourteen different researchers provide evidence that prepaid monetary incentives have a strong positive impact on the response rate in mail surveys. One of these studies is described here and an attempt is made to generalize from all eighteen about the relationship between size of incentives and reduction in nonresponse. These generalizations should be of value for the design of mail survey studies.
