Frank Hollenbeck writes in today’s Mises Daily:
Since 2008, the central bank has reduced interest rates to almost zero with little to show for it. You can bring a horse to water in a trough, pond, or lake, but you cannot make him drink. Most of the added liquidity has found its way into excess reserves. Banks are not lending because they have few creditworthy customers who want to borrow. The household sector is still deleveraging and has less appetite for more debt, and the business sector is careful about making future investments in a financial and economic environment on unstable footing. Businesses are keenly aware of the malinvestments never cleaned up after the last bubble and of the price distortions of current monetary policy. Why would businesses stick their necks out if they suspect a painful adjustment is around the corner?
Since the first channel has failed, only the second channel remains. Economists are generally in agreement, however, that there is no long-run trade-off between inflation and unemployment. The Keynesians and monetarists believe that there may be a short-run trade-off. If people have adaptive expectations, (based on the recent past) then monetary policy that creates inflation will reduce unemployment by lowering a worker’s real wages. Of course, once a worker realizes he has been fooled, he will demand an increase in nominal wages to bring his real wages back up to previous levels. The gain in employment is only temporary. If, instead, people base their expectations rationally and are not fooled, the neo-classical position, there is no short- or long-run trade-offs between inflation and unemployment.
