Privately optimal contracts and suboptimal outcomes in a model of agency costs
This paper derives the privately optimal lending contract in the celebrated financial accelerator model of Bernanke, Gertler and Gilchrist (1999). The privately optimal contract includes indexation to the aggregate return on capital, household consumption, and the return to internal funds. Although privately optimal, this contract is not welfare maximizing as it leads to a sub-optimally high price of capital. The welfare cost of the privately optimal contract (when compared to the planner outcome) is significant. A menu of time-varying taxes and subsidies can decentralize the planner?s ...

Gaps versus growth rates in the Taylor Rule
There are many possible formulations of the Taylor rule. We consider two that use different measures of economic activity to which the Fed could react, the output gap and the growth rate of GDP, and investigate which captures past movements of the fed funds rate more closely. Looking at these rules through the lens of a partial-adjustment Taylor rule, we conclude that the gap rule does a better job of explaining the actual funds rate data, and provides a better rule-of-thumb for understanding historical monetary policy.

Price-level and interest-rate targeting in a model with sticky prices
An examination of a standard sticky-price monetary model whose conditions are perturbed relative to the canonical real-business-cycle model by two varying distortions: marginal cost and the nominal rate of interest. The paper explores the implications of two monetary policies that are frequently advocated: (1) an inflation target and (2) an interest rate target.

The fiscal theory of the price level
A traditional function of the central bank is to control the price level. The fiscal theory of the price level challenges this assumption, arguing instead that the fiscal authority's budgetary policy is the primary determinant of the price level. The authors provide a critical review of the fiscal theory and its implications for monetary policy.

Taylor rules in a model that satisfies the natural rate hypothesis
The authors analyze the restrictions necessary to ensure that the interest-rate policy rule used by the central bank does not introduce real indeterminacy into the economy. They conduct this analysis in a flexible price economy and a sticky price model that satisfies the natural rate hypothesis. A necessary and sufficient condition for real determinacy in the sticky price model is that there must be nominal and real determinacy in the corresponding flexible price model. This arises if and only if the Taylor rule responds aggressively to lagged inflation rates.

Monetary policy and self-fulfilling expectations: the danger of forecasts
What rule should a central bank interested in inflation stability follow? Because monetary policy tends to work with lags, it is tempting to use inflation forecasts to generate policy advice. This article, however, suggests that the use of forecasts to drive policy is potentially destabilizing. The problem with forecast-based policy is that the economy becomes vulnerable to what economists term ?sunspot? fluctuations. These welfare-reducing fluctuations can be avoided by using a policy that puts greater weight on past, realized inflation rates rather than forecasted, future rates.

Explaining apparent changes in the Phillips curve: the Great Moderation and monetary policy
Observations that the Phillips curve may be deviating from historical norms are important to policymakers because deviations would imply that more or less output has to be sacrificed to achieve a permanent reduction in long-term inflation. But we argue that recent economic shocks and a shift in the Fed?s response to inflation may be leading economists to misestimate the curve.

Term Premium Variability and Monetary Policy
Two traditional explanations for the mean and variability of the term premium are: (i) time-varying risk premia on long bonds, and (ii) segmented markets between long- and short-term bonds. This paper integrates these two approaches into a medium-scale DSGE model. We consider two sources of business cycle variability: shocks to total factor productivity (TFP), and shocks to the marginal efficiency of investment (MEI). The ability of the risk approach to match the first moment of the term premium depends upon the relative importance of these two shocks. If MEI shocks are an important driver of ...

Monetary shocks, agency costs, and business cycles
This paper integrates money into a real model of agency costs. Money is introduced by imposing a cash-in-advance constraint on a subset of transactions. The underlying real model is a standard real-business-cycle model modified to include endogenous agency costs. The paper?s chief contribution is to demonstrate how the monetary transmission mechanism is altered by these endogenous agency costs. In particular, do agency costs amplify and/or propagate monetary shocks?

The benefits of interest rate targeting: a partial and a general equilibrium analysis
An argument that an interest rate peg is desirable because it mitigates the distortions that arise in a monetary economy, and that money growth should be procyclical in order to achieve the interest rate peg.
