The weakening of price and economic growth poses serious problems for the ECB

European Central Bank (ECB) Vice President Gonzal Thani said Friday that the link between price and economic growth weakened, making the central bank in the control of inflation is not only cost increase is even more difficult, so as to bring serious problems to decision-making officials.

In a scholarly-based speech, Gonzádse said that new research shows that the impact of exchange rate fluctuations on prices may be less than in the past, suggesting that the recent rally in the euro could be more modest to price than expected.

The major economies are in a relatively long steady expansion period, but the pay growth is sluggish, which makes decision makers feel confused. Salary growth is not only to curb inflation, but also to force the central bank to provide longer than expected to stimulate.

"The apparent disjunction between inflation and economic idle production seems to make it harder to interpret and control inflation, which has a significant impact on the implementation of monetary policy," said Gonzán Thani Europe at a conference.

"From the point of view of the decision maker, it is clear that the disjunction is so serious." He also pointed out that dealing with high inflation would have a greater drag on the real economy, but because of the need for large-scale stimulus, coping with low inflation is a test of the limits of policy instruments.
