The concepts of core and periphery remain ubiquitous and elusive in the European integration debate. This column documents the formation and evolution of a core and periphery in EMU, unearthing an increasingly integrated core, an entrenched periphery, and a third set of countries marked by in-and-out movements.  Using a novel measure to capture the probability of a country being classified as peripheral, it reveals that this probability positively correlates with euro membership and flexible product market regulations.

From the introduction of the euro in 1999 to the Greek crisis in 2010, the Eurozone witnessed external imbalances between countries at its core and those at its periphery. These imbalances have been attributed either to differences in competitiveness or to the effect of financial integration. This column argues that in order to understand the imbalances within the Eurozone, it is necessary to consider credit costs and capital flows. The lower real cost of credit for high-inflation countries must be taken into account, as well as the inflow of capital to the non-tradable sector that this implies. Monetary policy cannot be conducted in a ‘one size fits all’ manner.
