If the market rate has increased sufficiently, all fundamentalists will consider that market rate to be too high, and will expect it to go down in the future. Their weight in the formation of market expectations will be high, so that the weight given to the chartists becomes correspondingly small. We now implement these two assumptions about the speculative dynamics as follows. We write the change in the expected future exchange rate as consisting of two components, a forecast made by the chartists and a forecast made by the fundamentalists: Et (St+1 )/St = (Ect (St+1 )/St )mt (Ef t (St+1 )/St )1−mt (5) where Et (St+1 ) is the market forecast made in period t of the exchange rate in period t + 1; Ect (St+1 ) and Ef t (St+1 ) are the forecasts made by the chartists and the fundamentalists, respectively; mt is the weight given to the chartists and 1 − mt is the weight given to the fundamentalists.

A sensitivity analysis revealed that the results are not very sensitive to these parameter values. these different initial conditions. Note that small changes in the initial conditions lead to large and discontinuous displacements of the attractors. This characteristic is a natural result of the non-linear nature of our model. We return to this to give an interpretation to this phenomenon. 5. Sensitivity Analysis We obtain a multiplicity of fixed-point solutions for a relatively broad range of parameters.
