Globalisation offers many benefits, some of which cannot be separated from other types of policy. This column examines how the benefits from removing regulations that impede competition are partly contingent on openness to import competition. Using recent firm-level analyses of productivity growth, it argues that those firms that contribute the most to overall growth could also be held back by reduced openness, harming overall advances in incomes.

The negative impact of higher capital requirements under Basel II on the provision of trade finance has been cited as one of the factors behind the Great Trade Collapse. This column exploits the adoption of the Basel II framework in Turkey in 2012 to investigate how a shock to the supply of trade-specific finance (in this case, letters of credit) affected firm-level exports. Changes in the cost of letters of credit affected Turkish firms’ reliance on trade finance, but the regulatory shock did not affect firm-level export growth.

Innovation is typically seen as a cumulative process, with new technologies building on existing knowledge - but our knowledge of how progress in a specific area is influenced by knowledge in other, ‘upstream’ areas is limited. Using US patent data, this column identifies a stable ‘innovation network’ that serves as a conduit for cumulative knowledge development. Technological advances in one field can advance progress in multiple neighbouring fields, but will have a stronger influence on more closely related areas.

A high correlation of business cycles is usually seen as a key criterion for an optimum currency area. This column argues that the elasticity with which countries react to the common cycle is equally important. A country with a non-unitary growth elasticity relative to the common area will experience cyclical divergences at the peak and trough of the common cycle. Despite being characterised by highly-correlated business cycles, the Eurozone suffers from widely differing amplitudes.

EU budget reform is a key issue in policy debates, in particular the redistributive effects between member states. This column assesses redistribution within the EU budget over the period 2000 to 2014. It finds that the net redistributive impact of the EU budget is rather small and, contrary to common belief, that the revenue side is more progressive than the expenditure side.
