The Interest Rate

AbstractThis paper integrates a money and credit market into a static approximation of the baseline New Keynesian model based on a money-and-credit-in-the-utility approach, in which real balances and borrowing contribute to the household’s utility. In this framework, the central bank has no direct control over the interest rate on bonds. Instead, the central bank’s instrument variables are the monetary base and the refinancing rate, i. e. the rate at which the central bank provides loans to the banking sector. Our approach gives rise to a credit channel, in which current and expected future interest rates on the bond and loan market directly affect current goods demand. The credit channel amplifies the output effects of isolated monetary disturbances. Taking changes in private (inflation and interest rate) expectations into account, we find that - contrarily to BERNANKE and BLINDER (1988) - the credit channel may also dampen the output effects of monetary disturbances. The expansionary effects of a monetary expansion may be substantially diminished if the monetary disturbance is accompanied by a contractionary credit shock. In a dynamic version of our model, in which expectations are formed endogenously, we find that the credit channel amplifies output responses.

This paper studies the determinacy of equilibrium in a new Keynesian model with deep habits under different interest rate rules. The main finding is that an interest rate rule satisfying the Taylor principle is no longer a sufficient condition to guarantee determinacy. Including interest rate smoothing and a response to output deviations from steady state significantly enlarges the regions of determinacy. However, under all the simple interest rate rules considered, determinacy is not guaranteed for a very high degree of deep habits. Deep habits give rise to countercyclical markups, which is in line with empirical evidence and makes them an appealing feature in the study of demand shocks. The countercyclicality of markups also leads to multiple equilibria because of self-fulfilling expectations for a high degree of deep habit formation.

Abstract This paper develops a New Keynesian model featuring financial intermediation, short- and long-term bonds, credit shocks, and scope for unconventional monetary policy. The log-linearized model reduces to four equations – Phillips and IS curves as well as policy rules for the short-term interest rate and the central bank's long-bond portfolio (QE). Credit shocks and QE appear in both the IS and Phillips curves. In equilibrium, optimal monetary policy entails adjusting the short-term interest rate to offset natural rate shocks, but using QE to offset credit market disruptions. Use of QE significantly mitigates the costs of a binding zero lower bound.

Keynesian Model

We examine optimal monetary policy in a New Keynesian model with unemployment and financial frictions where banks produce loans using equity as collateral. Firms and households demand loans to finance externally a fraction of their flows of expenditures. Our findings show amplifying business-cycle effects of a more rigid loan production technology. In the monetary policy analysis, the optimal rule clearly outperforms a Taylor-type rule. The optimized interest-rate response to the external finance premium turns significantly negative when either banking rigidities are high or when financial shocks are the only source of business cycle fluctuations.

Keynesian Model

We introduce increasing returns to scale into an otherwise standard New Keynesian model with capital, and study the determinacy and E-stability of equilibrium under Taylor-type interest rate rules. With very mild increasing returns supported by empirical research, the conventional wisdom regarding the design of interest rate rules can be overturned. In particular, the “Taylor principle” no longer guarantees either determinacy or E-stability of the rational expectations equilibrium.
