This paper examines the time series properties of real GDP in the Euro area (EU 11), both prior to and after the adoption of the Euro in January 1999. We employ the relatively recent "optimal approximation" band pass filter developed by Christiano and Fitzgerald (2003) in order to identify a Euro-zone business cycle. We also utilise two alternative assumptions regarding the behaviour of the trend component of Euro area real GDP. The empirical results suggest that the single currency experiment appears to have reduced trend growth in the Euro zone, both ex-ante during the Maastricht nominal convergence phase, and also ex-post, during the period 2001Q1 to 2005Q4. With respect to cyclical behaviour, we identify a very robust measure of the Euro zone business cycle in the post 1994 period which does not appear to be sensitive to the particular assumption made regarding the trend rate of growth of real GDP. This type of result should facilitate a more accurate assessment of the extent to which individual countries and groups of countries are converged with respect to the Euro area business cycle.

AbstractThis paper employs Hansen's (1999) panel threshold regression model [Journal of Econometrics 39 (1999) 345–68] based on a time series dataset of 109 countries from 1960 to 2007 to investigate the threshold relationship between the change in real GDP per capita and the consumption size (consumption‐income ratio, APC). The results show that the consumption level should not exceed the 49.68% threshold of real GDP per capita for each country regardless of the income level. Also, the relationship between the change in real GDP per capita and the consumption size seems to have 'Armey curve' or 'inverted‐U shape' characteristic. In order to promote real GDP growth, our results suggest that the high‐income, low‐APC countries should encourage more consumption while the low‐income, high‐APC countries should encourage more saving.
