Replication Data for: Against the Flow: Differentiating Between Public Opposition to the Immigration Stock and Flow

Vast research on immigration lumps together native citizens' attitudes toward two different groups: the immigrant stock of non-naturalized resident aliens, and the immigrant flow, i.e. the future arrival of foreigners seeking to enter and live in the country. Does popular opposition to immigration distinguish between the two, and if so, how? We analyze theoretically the reasons the stock and flow might induce different views among natives, and present experimental evidence from the U.S showing that natives are systematically more accepting of the former. Our analysis indicates that this \"stock premium\" partly stems from a sense of moral obligation toward people residing in the country. Replicating two widely-cited experiments, we show that the stock-flow distinction has important implications for the interpretation of earlier findings on immigration attitudes, as well as for understanding voter preferences regarding policies aimed at curtailing immigration.
