Monetary Policy, Inflation Expectations and the Price Puzzle

This paper re-examines the VAR evidence on the price puzzle and proposes a new theoretical interpretation. Using actual data and two identification strategies based on zero restrictions and model-consistent sign restrictions, we find that the positive response of prices to a monetary policy shock is historically limited to the sub-samples that are typically associated with a weak interest rate response to inflation. Using pseudo data generated by a sticky price model of the US economy, we then show that the structural VARs are capable of reproducing the price puzzle only when monetary policy is passive. The omission in the VARs of a variable capturing expected inflation is found to account for the price puzzle observed in simulated and actual data.

The Monetary Policy of the European Central Bank

The first six years of ECB monetary policy are examined using a general framework that allows central bankers to weight differently positive and negative deviations of inflation, output and the interest rate from their reference values. The empirical analysis on synthetic euro-area data suggests that the objective of price stability is symmetric, whereas the objectives of real activity and interest-rate stabilizations are not. Output contractions imply larger policy responses than output expansions of the same size, while movements in the interest rate are larger when the level of the interest rate is relatively high. The hypothesis of M3 growth-rate targeting is rejected.

Evolving U.S. Monetary Policy and the Decline of Inflation Predictability

Using a structural VAR with time-varying parameters and stochastic volatility on post-WWII U.S. data, we document a striking negative correlation between the evolution of the long-run coefficient on inflation in the monetary rule and the evolution of the persistence and predictability of inflation relative to a trend component. Using a standard sticky-price model, we show that a more aggressive policy stance towards inflation causes a decline in inflation predictability, providing a possible interpretation for the findings of the structural VAR.

The price puzzle: fact or artefact?

This paper re-examines the empirical evidence on the price puzzle and proposes a new theoretical interpretation. Using structural VARs and two different identification strategies based on zero restrictions and sign restrictions, we find that the positive response of price to a monetary policy shock is historically limited to the sub-samples associated with a weak central bank response to inflation. These sub-samples correspond to the pre-Volcker period for the US and the pre-inflation targeting regime for the UK. Using a micro-founded New Keynesian monetary policy model for the US economy, we then show that the structural VARs are capable of reproducing the price puzzle on artificial data only when monetary policy is passive and hence multiple equilibria arise. In contrast, this model never generates on impact a positive inflation response to a policy shock. The omission in the VARs of a variable capturing the high persistence of expected inflation under indeterminacy is found to account for the price puzzle observed on actual data.

THE COST CHANNEL OF MONETARY POLICY AND INDETERMINACY

We study the conditions that guarantee equilibrium determinacy in a standard sticky price model augmented with a cost channel. A central bank that assigns some positive weight to the output gap in its reaction function makes the economy more prone to multiple equilibria relative to the standard case. The value of the threshold on the interest rate response to inflation is above one and depends on the fraction of firms that need to borrow their bills payment.

Measuring the time-inconsistency of US monetary policy

This paper offers an alternative explanation for the behavior of postwar US inflation by measuring a novel source of monetary policy time- inconsistency due to Cukierman (2002). In the presence of asymmetric preferences, the monetary authorities end up generating a systematic inflation bias through the private sector expectations of a larger policy response in recessions than in booms. Reduced-form estimates of US monetary policy rules indicate that while the inflation target declines from the pre- to the post-Volcker regime, the average inflation bias, which is about one percent before 1979, tends to disappear over the last two decades. This result can be rationalized in terms of the preference on output stabilization, which is found to be large and asymmetric in the former but not in the latter period.

Bank lending and monetary transmission in the euro area

To what extent does the availability of credit depend on monetary policy? And, does this relationship vary with bank characteristics? Based on a common source of balance sheet data for the four largest economies of the euro area over the period 1999-2011, we uncover three main regularities. First, the effect of monetary policy on bank lending is significant and heterogeneous in Germany and Italy, which are characterised by a large number of banks; but it is very weak in Spain and more homogeneous in France, where the banking industry has a higher degree of market concentration. Second, there is some evidence that monetary policy exerts larger effects on cooperative and savings banks with lower liquidity and less capital in Germany and savings banks with smaller size in Italy. Third, heterogeneity across groups of banks belonging to the same category in any particular country is found to be less pronounced. JEL Classification: C33, E44, E52, G21

A Century of Inflation Forecasts

We investigate inflation predictability in the United States across the monetary regimes of the twentieth century. The forecasts based on money growth and output growth were significantly more accurate than the forecasts based on past inflation only during the regimes associated with neither a clear nominal anchor nor a credible commitment to fight inflation. These include the years from the outbreak of World War II in 1939 to the implementation of the Bretton Woods Agreements in 1951 and from Nixons closure of the gold window in 1971 to the end of Volckers disinflation in 1983.

Evolving International Inflation Dynamics: Evidence from a Time-varying Dynamic Factor Model

Several industrialised countries have had a similar inflation experience in the past 30 years, with inflation high and volatile in the 1970s and the 1980s but low and stable in the most recent period. We explore the dynamics of inflation in these countries via a time-varying factor model. This statistical model is used to describe movements in inflation that are idiosyncratic or country specific and those that are common across countries. In addition, we investigate how comovement has varied across the sample period. Our results indicate that there has been a decline in the level, persistence and volatility of inflation across our sample of industrialised countries. In addition, there has been a change in the degree of comovement, with the level and persistence of national inflation rates moving more closely together since the mid-1980s.

Us Monetary Policy Rules: The Case for Asymmetric Preferences

This paper investigates the empirical relevance of a new framework for monetary policy analysis in which decision makers are allowed to weight differently positive and negative deviations of inflation and output from the target values. The specification of the central bank objective is general enough to nest the symmetric quadratic form as a special case, thereby making the derived policy rule potentially nonlinear. This forms the basis of our identification strategy which is used to evelop a formal hypothesis testing for the presence of asymmetric preferences. Reduced-form estimates of postwar US policy rules indicate that the preferences of the Fed have been highly asymmetric with respect to both inflation and output gaps, with the latter being the dominant source of nonlinearity after 1983.
