How do data revisions affect the evaluation and conduct of monetary policy?
Many economic data series are revised as more comprehensive information becomes available and as methodologies improve. Even the latest available data are subject to uncertainty, and at some point historical data may be replaced by more accurately measured observations. Because monetary policy decisions are made with an eye to the state of the economy, data uncertainty complicates the evaluation and conduct of monetary policy. ; Kozicki focuses on revisions to data that policymakers often examine when assessing monetary policy options. While other studies have looked at the impact of data ...

Breathing room for beta
This paper argues that a test of beta insignificance, commonly used in empirical studies of the CAPM, predisposes studies toward rejecting the CAPM. Under the null hypothesis of these tests, the CAPM is false. Consequently, insufficient evidence to reject the null is taken as sufficient evidence to reject the CAPM. Simulations suggest that this framework typically leads to false rejection rates of more than 1/2. An alternative test, with a null hypothesis consistent with the CAPM, is proposed. Based on statistics from published studies, the proposed test does not reject the CAPM.

Shifting endpoints in the term structure of interest rates
This paper links the term structure to perceptions of monetary policy. Long-horizon forecasts of short rates needed in empirical term structure models are heavily influenced by the endpoints, or limiting conditional forecasts, of the short rate process. Mean-reversion or unit roots are commonly assumed, but do not provide realistic yield predictions. Failures occur because neither accounts for historical shifts in market perceptions of the policy target for inflation. This paper links endpoint shifts to a learning model where agents must detect shifts in long-term policy goals. With ...

Term premia : endogenous constraints on monetary policy
Monetary policy evaluation using structural macro models suggests that historical monetary policy responds less aggressively to inflation and the output gap than would an optimal policy rule. However, these results are obtained using models with constant term premia. This paper shows how term premia may depend on the policy rule specification and policy rate uncertainty. A more aggressive policy rule involves an economically important increase in term premia. Consequently, conclusions about the specification of optimal monetary policy rules based on counterfactual simulations of models that ...

How useful are Taylor rules for monetary policy?
Over the past several years, Taylor rules have attracted increased attention of analysts, policymakers, and the financial press. Taylor rules recommend a setting for the level of the federal funds rate based on the state of the economy. Taylor rules have become more appealing recently with the apparent breakdown in the relationship between money growth and inflation. But, the usefulness of rule recommendations to policymakers has not been well established.> To be useful to policymakers, rule recommendations should be robust to minor variations in the rule specification. For example, if ...

Dynamic specifications in optimizing trend-deviation macro models
As noted in surveys by Goodfriend and King (1997) and Walsh (1998) and exemplified by models analyzed in Taylor (1999), there is encouraging progress in developing optimizing trend-deviation macro models that provide useful insights into the transmission and design of monetary policy. Several controversial features of a minimalist trend-deviation model, with optimizing households, firms, and bond traders, are examined. Dynamic specifications are suggested to improve the data-based realism, while preserving the simplicity, of the minimalist model.

Predicting inflation with the term structure spread
It is tempting to interpret empirical evidence in a number of recent studies as suggesting that term structure spreads help predict future inflation over moderate horizons of 3 to 5 years. This paper argues that common measures of the predictive power of the term structure spread for future inflation are misleading. In particular, R2s for estimated inflation-change equations can drastically overstate the predictive power of spreads. The paper explains why the overstatement is likely to be particularly large in countries whose monetary authorities have strong reputations for credibly targeting ...

Moving endpoints and the internal consistency of agents' ex ante forecasts
Forecasts by rational agents contain embedded initial and terminal boundary conditions. Standard time series models generate two types of long-run "endpoints"--fixed endpoints and moving average endpoints. Neither can explain the shifting endpoints implied by postwar movements in the cross-section of forward rate forecasts in the term structure or by post-1979 changes in survey estimates of expected inflation. Multiperiod forecasts by a broader class of "moving endpoint" time series models provide substantially improved tracking of the historical term structure and generally support the ...

Minding the gap : central bank estimates of the unemployment natural rate
A time-varying parameter framework is suggested for use with real-time multiperiod forecast data to estimate implied forecast equations. The framework is applied to historical briefing forecasts prepared for the Federal Open Market Committee to estimate the U.S. central bank?s ex ante perceptions of the natural rate of unemployment. Relative to retrospective estimates, empirical results do not indicate severe underestimation of the natural rate of unemployment in the 1970s.

Perhaps the FOMC did what it said it did : an alternative interpretation of the Great Inflation
This paper uses real-time briefing forecasts prepared for the Federal Open Market Committee (FOMC) to provide estimates of historical changes in the design of US monetary policy an in the implied central bank target for inflation. Empirical results and FOMC transcripts support a neglected interpretation of policy during the Great inflation of the 1970?s
