Title: Simultaneous Equations Linear Models with Forecast Feedback
Abstract: In this paper we first give the specification and stochastic assumptions for the general simultaneous
equations model with finitely many (multivariate) expectation terms. For sake of illustration we work out the
two-markets cobweb example given in the introduction. The next part contains the relevant results for models
with a single expectation term, thereby following the way adopted in Kottmann (1988) for single equation
models and arriving at similar conclusions: Under kind-of-ergodicity assumptions and in the influence of the
forecast terms is not too large, the OLS-forecasts will converge to (constrained) rational expectations.
present the specification and the results for the general model with finitely many expectation terms. The proofs
of these results are straightforward generalizations of those given before.
