Theoretical models of the exchange rate are developed where
information on the model is not fully available to agents. It is an
application of Benjamin Friedman's (1979) theme that full rational
expectations may be a possibility only in the long-run, even for
completely rational individuals. The thesis attempts to develop the
theory of exchange rate behaviour by considering some neglected
The three substantive chapters each consider specific aspects of
relevance to the determination of the exchange rate from an asset market
view of perfect capital mobility. These are the possible current
account inter-relationship, the persistence of interest rate
differentials between the two currencies and the subjectivity of and the
regress in beliefs across a decentralised market.
Generally, limited information on the model will give rise to
erroneous beliefs, on the one hand, and encourage the acquistion of
information and the revision of beliefs, on the other. Erroneous
beliefs will cause correlations between variables, which may not
normally occur inside full rational expectations. The revision of
beliefs will bring a particular source of non-stationarity to the data.
And the stability of certain learning forms may require limitations on
the degree of capital mobility.
These conclusions would suggest that any empirical work on
modelling the exchange rate may gain from relaxing certain a priori
restrictions, which properly belong to models with stronger assumptions
on the availability of information.
