central banks bought bonds

University of Chicago blames step two, low rates. But step one was buying debt from a single sector, government. Treasury and the debt cartel engineered the low rates, that was part of the tax and sequester agreement.  The tax payer cannot afford a ten year rate near 3%, and can barely afford the rate we pay now. That is the problem, no discretionary surplus in Congress makes federal debt shaky.

The paper,“Low interest rates, market power and productivity growth” by Ernest Liu, Atif Mian and Amir Sufi, examines the behavior of firms in a competitive marketplace as interests decline, and demonstrates that, although lower interest rates at first increase competitiveness through increased investment, they also increase the comparative advantage of large firms, thus after a time discouraging the smaller firms from investing and making the market less competitive. If low interest rates persist and approach zero, eventually even the larger firms stop investing, because they are no longer subject to significant competition and thus do not need to invest.The paper provides theoretical backing to and a possible mechanism for the observation set out in this column on several occasions in the last few years: that ultra-low interest rates in Japan, the Eurozone, Britain and the United States were closely correlated with unprecedented declines in the rate of productivity growth in those countries. In all the high-income industrial countries where interest rates were held artificially low after 2008, productivity growth by 2016 had effectively disappeared altogether, or close to it. The worst effects were seen in the eurozone and in Britain, where inflation continued, making real interest rates sharply negative. Even in Japan, where interest rates have been held artificially low for two decades, the productivity dearth worsened substantially after 2009.
