A. Kamara, THE RELATION BETWEEN DEFAULT-FREE INTEREST-RATES AND EXPECTED ECONOMIC-GROWTH IS STRONGER THAN YOU THINK, The Journal of finance, 52(4), 1997, pp. 1681-1694
The relation between default-free interest rates and expected economic
growth is substantially stronger than suggested by extant literature.
Futures-implied Treasury bill yield spreads are more highly correlate
d with future real consumption, investment, and GNP growth than spot s
preads. This stronger relation arises because using futures removes a
component of the spot term structure that covaries negatively with rea
l economic growth. Treasury forward rates from spot bills contain a pr
emium for the risk that short-sellers will default. This risk premium
is negatively related to expected economic growth.
