Forecasting future economic growth : the term structure of interest rates, volatility and inflation as leading indicators
… of future real economic activity. Steeper slopes presage increasing growth, and downward sloping term structures presage declining growth or even recession. Some instances of slope's misleading signals were recorded in 2006 (the term structure was flat, indicating decline in economic activity when …
