Financial Intermediation Versus Stock Markets in a Dynamic Intertemporal Model

We consider the transitions among intragenerational and alternative intergenerational financing and liquidity risk sharing mechanisms, in an overlapping generations model with endogenous levels of long-lived investments. The existence and characterization of a self-sustaining mechanism, stable across generations, is established. The long-run equilibrium outcome, in a proposal game across generations, is shown to depend on the risk aversion and propensity for early liquidity needs of the agents.
