The long climb

    The world economy is fitfully getting back to normal, but it will be a “new normal”. This phrase has caught on, even if people disagree about what it means. In the new normal, as defined by Pimco´s CEO, Mohamed El-Erian, growth will be subdued and unemployment will remain high. “The banking system will be a shadow of its former self,” and the securitization markets, which buy and sell marketable bundles of debt, will presumably be a shadow of a shadow. Finance will be costlier and investment weak, so the stock of physical capital, on which prosperity depends, will erode.
    The crisis invited a forceful government entry into several of capitalism´s inner sanctums, such as banking, American carmaking and the commercial-paper market. Mr El-Erian worries that the state may overstay its welcome. In addition, national exchequers may start to feel some measure of the fiscal strain now hobbling California. America´s Treasury, in particular, must demonstrate that it is still a “responsible shepherd of other countries´ savings.”
