Denmark, Finland, Norway and Sweden face similar problems of integrating large groups of immigrants, especially low-educated ones from outside the EU, into their labour markets. In this volume, researchers from across the Nordic Region analyse how labour market integration of immigrants can be promoted. Education policy, active labour market policy, social benefit policy and wage policy are analysed. A key conclusion is that no single policy is likely to suffice. Instead, various policies have to be combined. The exact policy mix must depend on evaluations of the trade-offs with other policy objectives.
