European Monetary System
Labour market effects

Many argue that the EMS has assisted disinflation by providing its members with a `credibility bonus': commitment to the Exchange Rate Mechanism has linked the non-German EC member countries' macroeconomic policies to Germany's and hence encouraged expectations that their inflation will ultimately converge on the German level. In Discussion Paper No. 598, Research Fellow Michael Artis and Paul Ormerod model the effect of German inflation on the inflation predictors of the other ERM members, using a model that marks the beginning of the `EMS period' (with a flexible break point) and in which they incorporate country-specific information on significant institutional changes derived from the relevant OECD Economic Surveys. For France and Italy, they find that German inflation had a significant influence on inflation after the break points; for Belgium and the Netherlands, it had a significant influence in both pre- and post-EMS estimates; German inflation itself was a notably stable process over the whole period. These results indicate that the ERM has caused German inflation to exert a significant influence on the other members' inflation processes, while its own has remained remarkably stable, which is entirely consistent with the `German leadership' hypothesis.
Artis and Ormerod also investigate the implications of ERM membership for European labour market structures by estimating a general model of wage determination. They report a marked reduction or even stagnation in the real wage growth of all the nonGerman members shortly after the ERM began and also a change in the trend of realized real wages after some significant disturbances to previous relationships, which coincided with a period of sharp institutional change in some countries.
These findings may indicate both the emergence of German inflation as a major predictor of domestic inflation and a modification of wage determination processes as a result of the `EMS effect'. Alternatively, the institutional adjustments may simply be correlated with the entry of German inflation into the other member countries' inflation processes, with a residual adjustment achieved through changes in the determinants of their wage inflation. The wage equations indicate that Belgium experienced a very sharp downward shift in the implied rate of increase of the real wage sought; in France and Italy there was a period of disturbed transition shortly after entry to the ERM. Although many of these institutional adjustments proved temporary, there is evidence of some large structural changes (e.g. in Belgium). While the `EMS effect' therefore appears to have had some effect on European labour markets, assessments of its extent must be qualified by also considering the strength of the rise in unemployment everywhere.

Is there an `EMS' Effect in European Labour Markets?
