We analyze the term structure of interest rates when markets anticipat
e a fiscal-policy change in the near future. Lf the anticipated change
consists of spending cuts, a fiscal retrenchment, interest rates of a
ll maturities increase, but short rates increase more than longer rate
s (the yield curve therefore becomes inverted), If however there is un
certainty on the type of the fiscal-policy change, the prediction of t
he model can be radically different: provided agents attach a positive
probability to an increase in public spending, the yield curve may be
come steeper in anticipation of a reform. (C) 1997 Elsevier Science B.
