Abstract:We study the determination of interest rates in a New Monetarist framework with public and private liquidity provision. We link the provision of liquidity to collateral constrains in the credit market, and explore the implications of this link for optimal monetary policy. We show that for decentralized trade it is optimal to have zero liquidity premium on interest-bearing assets, but for the credit market it is optimal to allow for positive liquidity premium on interest-bearing assets as long as lenders and borrowers (entrepreneurs) differ in time preferences and there is positive haircut for collateral assets. The Friedman rule is suboptimal because it traps the equilibrium real interest rate in its maximum possible value, which is detrimental to the credit market.
