  ABSTRACT: It is the aim of this paper to model involuntary unemployment in Magill and Quinzii's (2003) seminal stock market model with non-shiftable capital and affine equity-price expectations. In contrast to New-Keynesian macro-models, unemployment is not traced back to inflexible prices and wage rates, but to inflexible aggregate investment based on investors'“beliefs” (Farmer, 2020) about investment demand. After setting up the stock market model, sufficient conditions for the existence and dynamic stability of a Golden Rule steady state with involuntary unemployment are presented and the comparative dynamics of this steady state are investigated. While an increase in investor optimism decreases unemployment in the short and long run, a smaller savings rate does this only temporarily.
