This paper analyzes the puzzling behavior of real interest rates over
the 1970-1990 period. Using data on expectations of future prices chan
ges to estimate the expected real rate of interest, we find that the r
eal rate was not so low as reported in the 1970s nor so high as report
ed in the 1980s. However, the expected real rate is still substantiall
y lower in the 1970s than in the 1980s and the abrupt large structural
change that occurred in 1979-81 still exists.
