Evidence is mixed on the effects of multinational activity on productivity and competitiveness in host economies. This column provides new evidence that multinationals’ productivity effects may be previously under-estimated. Results suggest that ownership structure of multinationals and foreign acquisitions play an important role in driving aggregate productivity growth.

Economists have largely ignored the deep interdependency between integration and delegation. This column describes a new theory of integration and delegation choices aimed at shedding light on how these distinct elements of organisational design interact. Contrary to what is suggested by a naïve one-dimensional approach, the model predicts that delegation and outsourcing should be negatively correlated, a prediction that holds up well when the model is applied to data for thousands of firms across many industries and countries.
