The European Central Bank supports the Bundesbank in its appeals for higher wage deals in Germany, Der Spiegel magazine quoted ECB Chief Economist Peter Praet as saying on Sunday (27 July).

Low wage agreements were needed in some crisis-hit countries in the eurozone to bolster competitiveness, Praet said.

By contrast, in countries like Germany where "inflation is low and the labour market is in good shape", higher earnings increases were appropriate. This would help bring average wage developments in the eurozone in line with the ECB's inflation target of close to 2%, he said.

The Bundesbank historically has been a strong advocate of wage restraint, but with eurozone inflation stuck below 1% and consumer prices rising just 1% in June in Germany, Europe's biggest economy, some fear deflation.

Bundesbank Chief Economist Jens Ulbrich was widely reported to have encouraged German trade unions to take a more aggressive stance in wage negotiations, given the low levels of inflation.

Earlier this month, the German Bundestag gave the green light to a minimum wage of €8.50 per hour. The law, which will apply as of 1 January 2015, will be the first time that Germany has a minimum wage, although some exceptions will continue to apply in certain sectors until 1 January 2017.
