In its semi-annual autumn forecasts, the EU raised its growth forecast for
Germany this year to 3.7%, a fraction above the German government's own
forecast of 3.4%, which the Commission had also given as its most recent
estimate in an interim report in September.
For 2011, the EU raised its German growth forecast to 2.2% from 1.6% in its
spring estimate. That is also higher than the government's own current
forecast of 1.8%.
