Mundell om valutakurser, pengepolitikken og inflation

Professor Robert Mundell, der fik nobelprisen i 1999 for studier om internationale monetær økonomi, herunder teorien om optimale valutaområder, efterlyste for nylig fastkurspolitik mellem Dollar og Euro. Det skriver Sean Rushton på bloggen The Supply Side og i WSJ (23/5). Fastkurspolitik skal erstatte kvantitative lettelser i pengepolitikken, som er gennemført to gange siden 2009 (QE1 og QE2). Mundell forudser, at kursen på dollar i forhold til euro stiger, når QE2 udløber, hvilket vil føre til stagnation og skabe pres for en QE3. Rushton skriver:

"With a fixed exchange rate, prices could move free from the scourge of sudden deflation and inflation, allowing investment horizons and planning timelines to expand along with production levels on both sides of the Atlantic. To supercharge the U.S. recovery, he also recommends permanently extending the Bush tax rates and lowering the corporate income tax rate to 15% from 35%.

Above all, he made it clear that the volatile exchange rate is the responsibility of the U.S. Treasury, not the central bank. Without a breakthrough on exchange rates, he predicted another dollar appreciation following QE2, resulting in a return to recession and a worsening of the U.S. debt crisis. This would likely lead to a third round of quantitative easing, continuing the dysfunctional cycle".
