Economic integration has certainly deepened and, more recently, changed enormously. Until the late 1990s integration was mostly trade-centred, while it now can be better described as institutions-centred. This column introduces the notion of ‘institutional integration’, identifies its main features, and provides estimates of its net benefits. With one of the first applications of the synthetic difference-in-differences estimator and using data from the 1995 enlargement of the EU, the authors find that the failure to embrace institutional integration by Norway (compared to ‘only’ embracing deep integration) generates yearly productivity losses of about 0.6 percentage points.
