The advantages or disadvantages firms experience as a result of their size, referred to in the economic literature as returns to scale, are of central importance in many economic models. Increasing returns to scale, whereby unit costs decrease as output volume increases, could explain productivity differences between Europe and the United States. We present fresh evidence on the returns to scale of European firms: most exhibit constant returns to scale, but a non-trivial share also show increasing returns to scale.

A new weekly activity index (WAI) published by the Bundesbank is designed to measure real economic activity in Germany in a timely manner. Measured by the WAI, economic activity between 16 March and 14 June 2020 was 7.4% below the activity recorded between 16 December 2019 and 15 March 2020.

Germany’s current account recorded a surplus of €21.3 billion in November 2020, down €1.6 billion from the previous month’s level. This was primarily attributable to a decrease in the goods account surplus. By contrast, the surplus in invisible current transactions, which comprise services as well as primary and secondary income, expanded only slightly.
