Collateral monetary equilibrium with liquidity constraints in an infinite horizon economy.

This paper considers an infinite-horizon monetary economy with collateralized assets. A Central BanK lends money to households by creating short- and long-term loans. Households can deposit or borrow money on both short- and long-term maturity loans. If households want to sell a financial asset, they are required to hold certain commodities as collateral. They face a cash-in-advance constraints when buying commodities and financial assets. Under Uniform or Sequential Gains to Trade Hypothesis, the existence of collateral monetary equilibrium is ensured. I also provide some properties of equilibria, including the liquidity trap.
