The Central-Bank Balance Sheet as an Instrument of Monetary Policy

While many analyses of monetary policy consider only a target for a short-term nominal interest rate, other dimensions of policy have recently been of greater importance: changes in the supply of bank reserves, changes in the assets acquired by central banks, and changes in the interest rate paid on reserves. We extend a standard New Keynesian model to allow a role for the central bank's balance sheet in equilibrium determination, and consider the connections between these alternative dimensions of policy and traditional interest-rate policy. We distinguish between “quantitative easing” in the strict sense and targeted asset purchases by a central bank, and argue that while the former is likely be ineffective at all times, the latter dimension of policy can be effective when financial markets are sufficiently disrupted. Neither is a perfect substitute for conventional interest-rate policy, but purchases of illiquid assets are particularly likely to improve welfare when the zero lower bound on the policy rate is reached. We also consider optimal policy with regard to the payment of interest on reserves; in our model, this requires that the interest rate on reserves be kept near the target for the policy rate at all times.

Monetary policy under sudden stops

This paper proposes a model to investigate the effects of monetary policy in an emerging market economy that experiences a sudden stop of capital inflows. The model features credit frictions, debt denominated in foreign currency, imported inputs, and households that have access to the international capital market only indirectly, through their ownership of leveraged firms. The sudden stop is modeled as a change in the perceptions of foreign lenders that brings about an increase in the cost of borrowing. I show that the higher the elasticity of foreign demand, the lower the contraction in output - leading, at the extreme, to the possibility of an expansion, depending on policy. A second result is that the recession is most severe in a fixed exchange rate regime. Taylor rules that react to inflation and output are more stabilizing. A comparison of alternative rules shows that low commitment to inflation stabilization allows for less contraction in output and even expansion but at the cost of much stronger contraction in capital inflows and higher interest rates. Credibility is also shown to have an important role, with low credibility and the risk of loose policy implying increased trade-offs, stronger contraction of the economy, and higher interest rates.Emerging markets ; Monetary policy ; Capital movements ; Loans, Foreign

Credit Spreads and Monetary Policy

We consider the desirability of modifying a standard Taylor rule for interest rate policy to incorporate adjustments for measures of financial conditions. We consider the consequences of such adjustments for the way policy would respond to a variety of disturbances, using the dynamic stochastic general equilibrium model with credit frictions developed in C�rdia and Woodford (2009a). According to our model, an adjustment for variations in credit spreads can improve upon the standard Taylor rule, but the optimal size of adjustment depends on the source of the variation in credit spreads. A response to the quantity of credit is less likely to be helpful. Copyright (c) 2010 The Ohio State University.
