A group of dozens of companies is pledging to invest at least 631 billion euros ($733 billion) in Germany over the next three years. That sends a signal of confidence in Europe’s biggest economy as the new government tries to breathe new life into it. The economy has shrunk for the past two years and is expected to stagnate this year. Chancellor Friedrich Merz’s administration has made revitalizing it a top priority since it took office May 6. On Monday, Merz welcomed representatives of an initiative titled “Made for Germany” to the chancellery to send a signal of confidence from and to private investors. The group currently includes 61 companies from across the economy.
