Resumen de After the immigration shock: The causal effect of immigration on electoral preferences

Rune Jørgen Sørensen

• The influx of immigrants to Norway over the last decades is a large-scale natural experiment. This paper exploits municipal-level variations in the immigrant population (1977–2011) to estimate the causal effects on voter support for the right-wing, anti-immigration Progress Party. The results indicate that voters keep incumbents accountable for permissive immigration policies. Immigration from non-Western countries (Africa, Asia, Latin America) has increased electoral support for the Progress Party. However, the effects are quite modest and noticeable only in the initial phases of immigration. Survey data covering ten elections (1989–2011) indicate a similar development in anti-immigration attitudes. The primary immigration shock tends to burn out quite fast as people get direct experience of immigrants on a daily basis.
