Figure 2
Average GDP per capita growth in Euro Area Member States (% p.a.): difference-in-difference to the US and an average of selected mature non-euro area (NEA) countries (1998-1992 vs. 1991-1981; 2009-1999 vs. 1998-1992; 2018-2010 vs. 2009-1999)

Source: Author’s compilation based on IMF data. Euro area aggregates for unemployment (before 1991) and inflation (before 1992) are calculated based on individual EAMS data (the original EAMS + Greece) weighted by the respective EAMS population share; for GDP growth (before 1992) and government debt-to-GDP (before 1995) the weighting is performed by using the respective EAMS shares in total GDP.
