Chapman points out that the Phillips curve did not hold in low inflation years since 1948 when low inflation was accompanied by low unemployment and higher growth rates. It did hold in the higher inflation years after 1948 when higher inflation was accompanied by high unemployment and low growth rates. So can the Federal Reserve hold onto the idea of a Philips curve hoping that higher inflation will somehow lead to lower unemployment and higher growth as it lowers interest rates. What it may end up doing is hurting the dollar, while increasing inflation and leading to lower growth. Without the demand for Treasurys the way there is now because of the confidence in the dollar, interest rates would rise and domestic savings would be diverted to service the debt, and output would be lower and prices higher. McKinnon at Stanford and others have been arguing the case for a strong dollar in the WSJ recently. Chapman is accepting that interest rate cuts may help the economy but only by a little bit in the current situation and temporarily because there are too many forces at work pushing the economy into recession. So the comparitively small dividends from interest rate cuts should not be allowed to give up the bigger dividends from having international confidence in the dollar not erode. Especially as the current market imbalances cannot be fixed by the mechanism of interest rates, and its not the Fed's job to fix the considerable challenges facing the economy today which will take time to work out and require political leadership from Congress and a new President.
