Abstract

Under the assumption that the income Yt follows a Samuelson-Hicks type of model, we calculate a policy variable Gt, in closed form, so that Yt satisfies an ideal law Yt = F(Ut*), Ut* being an influence variable. The approach uses some recently developed tools of non-linear feedback design; it is fully parameterized and allows the dynamic change of the influence variable Ut*. From the control theory point of view, we solve a non-linear model matching problem and produce a policy instrument that shapes the income Yt within a desired family of behaviours.
