Abstract
This paper provides a selfcontained review of the introduction of the animal spirits hypothesis into the infinite horizon optimal growth model. The analysis begins with an economic discussion of Pontryagin’s maximum principles. Thereafter, I develop a version of the increasingreturns BenhabibFarmer model by showing the possible suboptimality of the central planner solution and deriving the bifurcation condition for indeterminacy. Moreover, I give some insights on how to model intrinsic and extrinsic uncertainty. Finally, analysing the equilibrium condition of the labour market, I provide an intuitive rationale for the mechanism that in this model might lead prophecies to be selffulfilling.
