| Abstract: | If individuals receive utility directly from the value of their wealth, equilibrium may be indeterminate so that sunspot equilibria may exist. In such an equilibrium, the price of an asset may fluctuate stochastically, as a result of spontaneous revisions of agents' expectations. A neoclassical growth model with such a utility function is used to show that those fluctuations in asset prices can generate co-movement among output, consumption and investment, even without assuming non-convex technology. In particular, numerical results show that the model can replicate well the business cycles in Japan over the period 1986–1999. |
