Growth rates have been stubbornly low since the financial crisis, and many have noted that the interest rate environment has been weakening since the 1980s. This column places recent episodes in the context of longer-term economic history, going back to the 14th century.

There remains, however, ample potential for innovation in payment systems.

This column uses data on Norwegian banks to show that efficiency may be eroded by international financial flows in a small open economy. This raises several challenges for central banks and financial regulatory agencies in such economies.
