This paper surveys the economic impacts of immigration for host countries. Empirical
evidence is drawn from the older and extensive literature regarding traditional destination coun-
tries like the US and Canada. However, this review also emphasizes the recent experiences of
Northern Europe and Scandinavia; a central goal is to highlight studies and lessons that have
particular application within this region. Migrant ows to some European countries are now
of similar magnitude to ows to the US, and it is helpful to identify relevant lessons from the
experiences of the US and other traditional destination countries. Looking forward, the hetero-
geneity in recent European experiences and policy environments provides an excellent laboratory
for identifying immigrations e¤ects in a new setting.
