This paper attempts to provide a logical overview of the literature which e
xploits survey data to examine issues of expectations formation and risk av
ersion in financial markets. Our survey suggests that: short term expectati
ons are excessively volatile and exhibit bandwagon effects, while longer te
rm expectations appear to be regressive and therefore stabilising; in bond
and foreign exchange markets the standard result of forward rate biasedness
is due in part to time-varying premia; recent research using disaggregate
foreign exchange survey data demonstrates the importance of heterogeneous e
xpectations.
