The inflow of low-skilled migrants may encourage natives to upgrade their skills, taking advantage of immigrant-native complementarity. This column uses exogenous dispersion of refugees in Denmark to investigate this issue. The findings confirm that for low-skilled native workers, the presence of refugee-country immigrants spurred mobility and increased specialisation into complex jobs.

Business investment in advanced economies contracted sharply during the global crisis and has recovered little since. This column argues that the main factor holding back investment is overall economomic weakness. In some countries other contributing factors include financial constraints and policy uncertainty.

An oft expressed view is that the Eurozone is a straitjacket on periphery members and income convergence has slowed, halted or reversed.  This column argues that EZ convergence never stopped. What changed was the type of convergence. Today’s convergence is neither nominal nor real, it is structural.  Structural convergence presents a basis for renewed real convergence. However, for this to happen, the right institutions and policies need to be in place at both European and national levels.

Despite a significant progress over the past decades, European integration still needs improvement in some areas. This column presents a long-term narrative of European integration by using a recently published European index of regional institutional integration. The index maps developments in European integration from 1958 to early 2015 on the basis of a new monthly dataset. The evidence shows that successful integration could be achieved with reforms that are inclusive, widely explained, understood, and accepted.
