SUNSPOTS AND CREDIT FRICTIONS [PDF]
Macroeconomic Dynamics, 2012 We examine a general equilibrium model with collateral constraints and increasing returns to scale in production. The utility function is nonseparable, with no income effect on the consumer's choice of leisure. Unlike this model without a collateral constraint, we find that indeterminacy of equilibria is possible.
