Distortionary effects of inflation on relative prices are the main argument for inflation stabilization in macro models with sticky prices. Under indexation of non-optimized prices, those models imply a nonlinear and dynamic impact of inflation on the cross-sectional price dispersion (relative price or inflation variability, RPV). Using US sectoral price data, we estimate such a relationship between inflation and RPV, also taking into account the endogeneity of inflation by using two- and three-stage least-squares and GMM techniques, which turns out to be relevant. We find an effect of (expected) inflation on RPV, and our results indicate that average (??trend??) inflation is important for the RPV?Cinflation relationship. Lagged inflation matters for indexation in the CPI data, but is not important empirically in the PPI data.  相似文献

This paper addresses three related aspects of monetary and fiscal management in Europe and elsewhere. First, I discuss the implications of economic integration for monetary and fiscal policy, especially the narrow focus on low inflation as the main objective of monetary policy. I argue that because inflation springs from several sources, monetary authorities held responsible by law for maintaining low inflation need to exercise their newfound independence by reserving the right to address all sources of inflation. In this context, I also ponder the question as to whether the increased independence of fiscal policy from short-term political interference would be desirable. Second, I present new empirical evidence of the relationship between inflation, finance, and economic growth across countries, arguing that long-run growth considerations provide an important additional justification for why price stability ought to remain a priority of independent policy makers. Third, I review some further aspects of the relationship between fiscal policy and economic growth, emphasizing the traditional three-pronged role of fiscal management: stabilization, allocation, and distribution, all of which can be conducive to growth. The argument leads to the conclusion that only the stabilization function of fiscal policy and, perhaps, some aspects of the allocation function as well could be usefully delegated in an attempt to immunize them from shortsighted and socially counter-productive political interference, but not the distribution function.  相似文献

In this paper we analyze two different target regimes, flexible inflation targeting and nominal income targeting, under discretion in a simple dynamic macro model. The key results of our paper are: First, for both targeting regimes optimal monetary policy response leads to a shock-dependent feedback rule. Second, a demand shock is completely offset by both monetary strategies. Third, in case of a supply shock there is a significant difference between the two different targeting regimes. Under inflation targeting the policy makers face a trade-off between inflation and output stabilization. This trade-off depends on the weight Φ the policy makers attach to output stabilization relative to inflation stabilization in the loss function. In contrast, under nominal income targeting policy makers face a constant trade-off between inflation and real output growth: an increase in inflation leads to a fall in real output growth by an equal amount. Furthermore, in Appendix A we analyze a (linear) commitment solution for inflation targeting and compare it with the discretionary case. Under commitment, inflation is smaller and the output gap is larger than under discretion. In Appendix B, we investigate inflation targeting in a two-period time-lag version of the model. The qualitative results on the trade-off between inflation and output growth remain the same as in the basic model without time lag.

This study investigates the role of hybrid inflation-price-level targets as a solution to the well-known stabilization bias problem that arises under discretionary policies. The analysis shows that social welfare will be improved by employing a weighted average of inflation and price level as one of the central bank's target variables in addition to the output gap growth target. The reason is that imposing the optimal hybrid target will reduce inflation variability in a highly efficient way. In particular, the optimal hybrid regime outperforms other previously suggested regimes when the degree of inflation persistence is moderate.  相似文献

This paper explores the role that inflation forecasts play in the uncertainty surrounding the estimated effects of alternative monetary rules on unemployment dynamics in the euro area and the US. We use the inflation forecasts of 8 competing models in a standard Bayesian VAR to analyse the size and the timing of these effects, as well as to quantify the uncertainty relative to the different inflation models under two rules. The results suggest that model uncertainty can be a serious issue and strengthen the case for a policy strategy that takes into account several sources of information. We find that combining inflation forecasts from many models not only yields more accurate forecasts than those of any specific model, but also reduces the uncertainty associated with the real effects of policy decisions. These results are in line with the model-combination approach that central banks already follow when conceiving their strategy.  相似文献

This paper examines a Rose-Wicksell, as opposed to a Stein-Keynes-Wicksell, model of Monetary Dynamics. Here, all money is of the “pure credit,” or “inside,” variety. Suppliers of money (banks) do not suffer from money illusion just as demanders do not; their decision to supply real balances is, likewise, based on profit maximization. The stability properties of the model are derived both in the short and the growth runs. It is shown that if interest is paid on demand deposits and if this rate is manipulated by the Central Bank, according to the rate of inflation, then all sources of instability can be eliminated. Moreover, stabilization of the short run guarantees stabilization of the growth model.  相似文献

The main objective of this article is to reexamine the role of the Phillips curve for monetary policy analysis in South Africa by augmenting the model for major structural changes in the balance-of-payments and labor market. The main findings show that a linear Phillips curve with an output gap in levels accurately describes South Africa's nontrended inflation experience during 1971(Q1)–1984(Q4), whereas a piecewise concave curve with an output gap in growth rates correctly predicts the decelerating inflation pattern during 1986(Q1)–2001(Q2). The concave curve after 1985 imparts a deflationary bias that requires expansionary demand-side policies to stabilise the inflation rate. An important corollary is that expansionary demand-side policies can raise the average growth rate of the output gap over time without sacrificing stabilization objectives.

The primary goal of this article is to investigate whether properly modelling real-time data and optimal real-time decision-making of a monetary planner provides new insights into monetary policy behaviour and outcomes. This article extends a variant of the asymmetric preference model suggested by Ruge-Murcia to investigate the use of real-time data available to policymakers when making their decisions and revised data which more accurately measure economic performance, but is only available much later. In our extended model, the central banker targets a weighted average of revised and real-time inflation together with a weighted average of revised and real-time output. Moreover, we allow for an asymmetric central bank response to real-time data depending on whether the unemployment rate is high or low. Our model identifies several new potential sources of inflation bias due to data revisions. Our empirical results suggest that the Federal Reserve Bank focuses on targeting revised inflation during low unemployment periods, but it weighs heavily real-time inflation during high unemployment periods. The inflation bias due to data revisions is comparable in magnitude to the bias from asymmetric central banker preferences with the bias being somewhat larger during high unemployment.  相似文献

Using a New Keynesian framework, this paper shows that, under optimal discretion and optimal pre‐commitment in a timeless perspective, imperfect transparency about the relative weight assigned by the central bank to output‐gap stabilization generally reduces the average reaction of inflation to inflation shocks and the volatility of inflation, but increases those of the output gap in static and dynamic terms, and more so when inflation shocks are highly persistent. When inflation shocks are moderately persistent, opacity could improve social welfare if the weight assigned to output‐gap stabilization is low and this is more likely under pre‐commitment than under discretion.  相似文献

Using a small empirical model of inflation, output, and money estimated on U.S. data, we compare the relative performance of monetary targeting and inflation targeting. The results show monetary targeting to be quite inefficient, yielding both higher inflation and output variability. This is true even with a nonstochastic money demand formulation. Our results are also robust to using a P∗ model of inflation. Therefore, in these popular frameworks, there is no support for the prominent role given to money growth in the Eurosystem's monetary policy strategy.  相似文献

Households' inflation perceptions and expectations play a key role in many dynamic macroeconomic and monetary models and are important for the ability of central banks to reach their objective of price stability. This paper revisits the issue of overestimation bias in inflation perceptions and expectations based on new and unique microdata from the Danish part of the EU-Harmonised Consumer Expectations Survey linked to rich household-level data from administrative registers. The analysis shows that accounting for even several of the household characteristics and social gradients usually addressed in the literature is far from sufficient to explain the inflation perception bias. Furthermore, we find that respondents participating in the survey more than once tend to be persistent in their degree of perception bias and that overpessimistic households have larger perception bias than other households. This indicates that inflation perception bias is related to fundamental personality traits. Finally, households' expectations of the future inflation level tend to be mean reverting and associated with the same types of bias as inflation perceptions.  相似文献

This paper offers an alternative explanation for the occurrence of an inflation bias with and without an output goal exceeding natural output. A monetary game model is developed from which an inflation bias emerges because the policymaker increases money growth in order to avoid a recession due to a possible negative control error. Whereas higher additive instrument uncertainty increases the inflation bias, higher multiplicative uncertainty decreases it. Delegating monetary policy to an independent and conservative central banker decreases the inflation bias for all types of control errors.  相似文献

In this paper, we examine the inflation persistence puzzle by applying the robust control approach of Hansen and Sargent (2008). In line with the literature suggesting that inflation persistence may be affected by the monetary policy design and its institutional characteristics, we find that inflation persistence is positively related to the central bank's preference for model robustness. In effect, model uncertainty and robust decision making may be considered as a mechanism generating inflation persistence, for a given non-zero degree of autocorrelation in supply-side shocks. Further, the policy implication is that the central bank's monetary policy under model uncertainty renders, in terms of the sacrifice ratio, the output-cost of inflation stabilization more important.  相似文献

This paper develops a nonlinear vector autoregression of inflation and money growth subject to changes in regime. The regimes are fully characterized by the mean and variance of inflation and are conjectured to be the result of alternative government policies. Agents are unable to observe directly whether government actions are indeed consistent with the inflation rate targeted as part of a stabilization program. However, as part of their money demand decision, agents construct probability inferences regarding the regime. Government announcements are assumed to provide agents with additional, possibly truthful information regarding the regime.  This specification is estimated using data from the Israeli and Argentine high-inflation periods. Results indicate that the successful stabilization program implemented in Israel in July 1985 was more credible than either the earlier Israeli attempt in November 1984 or the Argentine programs. Government's signaling might simplify the agents' inference problem and increase the speed of their learning but, under certain conditions, it might also increase inflation volatility. Welfare gains from a temporary increase in real balances might be high enough to induce agents to raise their money demand in the short-term even if they are uncertain about the nature of government policy and the eventual outcome of the stabilization attempt. Statistically, the model restrictions cannot be rejected at the 1% significance level. First version received: August 1998/Final version received: January 1999  相似文献

This study examines the transmission and response of inflation uncertainty and output uncertainty on inflation and output growth in the UK using a bi-variate EGARCH model. Results suggest that inflation uncertainty has positive and significant effects on inflation before the inflation-targeting period, but that the effect is significantly negative after the inflation-targeting period. On the other hand, output uncertainty has a negative and significant effect on inflation and a positive effect on growth, while oil price rises significantly increase inflation for the UK. Results also indicate that inflation uncertainty significantly reduces output growth before and after the inflation-targeting period. These findings are robust and the Generalized impulse response functions corroborate the conclusions. These results have important implications for an inflation-targeting monetary policy, and for stabilization policy in general.  相似文献

This paper investigates the linkages between inflation, economic growth and terrorism using annual frequency data over the period of 1971–2010, the maximum time period for which consistent data is available for Pakistan. The ARDL bounds testing approach to cointegration has been applied while robustness of long run relationship is established by using rolling window approach. The empirical evidence confirms the cointegration between inflation, economic growth and terrorism in Pakistan. An increase in inflation raises terrorist attacks while economic growth is also a major contributor to terrorism. Moreover, bidirectional causality is found between inflation and terrorism as investigated by the VECM Granger-causality approach while variance decomposition approach also supports the findings by the VECM Granger causality analysis. Our results therefore points to benefits of pursuing sustainability of low inflation in reducing terrorism. However, it also implies some difficulties for policy-makers in Pakistan in their pursuit for economic growth as latter would result in an increase in terrorism activities crowding out some of the benefits of economic growth.  相似文献

In this classroom experiment, students develop a price index based on candy-purchasing decisions made by members of their class. They use their index to practice calculating inflation rates and to consider the strengths and weaknesses of the consumer price index (CPI). Instructors can use the experiment as an introduction to the topic of inflation and how it is measured. The exercise also provides a concrete example of the sources of bias in the CPI, promoting discussion of the measures the Bureau of Labor Statistics has taken to reduce bias. The experiment, including follow-up discussion, fits into a 50-minute class period. The authors and other professors have used the exercise in introductory and intermediate macroeconomics courses, in classes of 10 to 135 students.  相似文献

This paper analyzes the relevance of the inflation targeting (IT) policy in achieving its primary goal of medium-term price stability. Contrary to previous studies, we propose, in this work, a new approach; an intermediate approach that consists in conducting a time-series analysis (employed in the literature under unilateral cases-absolute approach) with a comparison of inflation performance of IT countries and those of non-IT countries (comparison made in literature under the relative approach). Empirically, we employ a frequency analysis based on evolutionary spectral theory of Priestley (1965–1996) in order to distinguish between different inflation horizons; short-run and the medium-run inflation rates. To check the stability of spectral density functions for inflation series for each country under studied frequencies, we apply a Bai and Perron (2003a,b) test. Our results show that after IT framework implementation, there is no break point in inflation series in short and medium terms. This result is not verified for non-IT countries. Therefore, IT is more relevant in achieving price stability and consequently more effective on inflation expectation anchoring than other monetary policies.  相似文献
