The yield curve, recessions, and the credibility of the monetary regime

"This paper brings historical evidence to bear on the stylized fact that the yield curve predicts future growth. The spread between corporate bonds and commercial paper reliably predicts future growth over the period 1875-1997. This predictability varies over time, however, particularly across different monetary regimes. In accord with our proposed theory, regimes with low credibility (high persistence of inflation) tend to have better predictability"--National Bureau of Economic Research web site.
