Berlin, July 10 (BridgeNews) - Presenting the lowest economic growth forecast issued by a leading research institute so far, Berlin-based think-tank DIW lowered its German economic growth outlook to 1.0% for this year from 2.1% and to 2.3% for next year. As measurements to stimulate growth, the institute urged the European Central Bank to cut interest rates while euro-zone countries should accept higher deficits because a "rigid holding on to agreed deficit targets would provoke a recession."
