Finance explains the difference between the United States and the euro zone
A significant part of the growth gap between the United States and the euro zone since the crisis can probably be attributed to two aspects of finance: The stop to capital mobility between the euro-zone countries and the segmentation of the euro zone’s financial markets along country lines has created a major inefficiency in the euro zone that does not exist in the United States: savings in one country no longer finance investments in other countries; The weakening of euro-zone banks, whose profitability and return on equity have become low as a result of flat yield curves and regulatory holdings of very-low-yielding assets. Accordingly, banks have shrunk , cannot attract capital and have difficulty taking risks.
