In a survey experiment with 8,500 participants from Italy, Germany and Hungary, we find that providing information about the positive relationship between allowing more migrant in a country and its economic prospects (via the influx of more working-age individuals) increased support for more open immigration policies. A related real-stake task conveyed findings consistent with the participant's stated policy preferences. Information of economic consequences affected policy preferences by alleviating the influence of overall political and cultural views on these preferences, especially for right-wing leaning and more cultural identitarian respondents.
