Optimal Monetary Policy in China

Using the structural vector autoregression model, we estimate the current responses of monetary policy to contemporaneous shocks from macroeconomic variables. Our findings indicate that the People's Bank of China responded to inflation and output changes, but did not react to asset price fluctuations during the period from January 1997 to March 2010. The optimal monetary responses to exogenous shocks are also examined. It is revealed that using asset prices to formulate monetary policy would not help to improve monetary authorities' performance in lowering the volatilities of output growth and inflation while keeping output growth and inflation in their safety zones. The effectiveness of monetary policy and fiscal policy in reacting to external shocks is also discussed.     

Low Inflation,Pass-through,and a Discrete Inflation-targeting Framework for Monetary Policy in China

The performance of inflation in China over the past few decades has been remarkable. This paper characterizes the statistical nature of the inflation series in China over the past quarter of a century and presents an interesting scenario of large decline in inflation pass-through accompanied with low inflation since the end of the 1990s. How should monetary policy in China be conducted under these new economic conditions? We propose a discrete inflation-targeting framework for monetary policy,which is likely to be suitable for the regime of low inflation and inflation pass-through. The advantages and caveats of adopting such a framework are also discussed.     

Why is Inflation in China a Monetary Phenomenon？

This paper proposes that inflation in China during the post‐reform era (1978 onwards) is always a monetary phenomenon. We construct a multivariate dynamic model based on Friedman's quantity theory of money and use the standard Granger causality test to show that money growth contains significant predictive power for inflation during the underlying period. The finding is robust to alternative measures of monetary aggregates and both closed and open economy frameworks. The baseline finding of the paper indicates that quantitative tools remain the most important policy instruments for China to manage its inflation effectively.     

New Keynesian Explanations of Cyclical Movements in Aggregate Inflation and Regional Inflation Differentials

What determines the cyclical behavior of aggregate inflation and regional inflation differentials? The answer has strong implications for monetary policy and in Europe for the Stability and Growth Pact. In the United States, inflation rates move pro-cyclically, and across the Euro Area, inflation differentials are positively correlated with growth differentials. This suggests that demand shocks are the primary determinants of the cyclical behavior of aggregate inflation and regional inflation differentials. In this paper, we discuss New Keynesian explanations of these correlations, and we argue that demand shocks are either missing or inadequately modeled in the in typical New Keynesian model.     

Effect of Money Supply on Real Output and Price in China

Over the past 30 years, China has achieved remarkable long-term economic growth. Using quarterly data, we study the effects of money supply on real output and inflation in China between 1993 and 2008. To this end, we use money supply shocks afler filtering out the expected component of the money supply. Our findings provide evidence supporting the asymmetric effect of positive and negative money supply shocks on real output and inflation in China. That is, real GDP growth in China responds to negative money supply shocks but not positive money supply shocks. In addition, inflation responds to positive money supply shocks but not negative money supply shocks. We conclude that the People＇s Bank of China＇ s policy of steady monetary growth appears to be appropriate. Our study offers important policy implications for China.     

Central Bank Autonomy,the Exchange Rate Constraint and Inflation: The Case of Italy, 1970–1992

This paper analyzes the determinants of inflation in Italy over the period 1970–1992. Particular emphasis is placed on the role of central bank independence in influencing monetary growth, and on the role of monetary growth and of the Exchange rate Mechanism (ERM) in affecting inflation. In the 1970s and early 1980s, when the Bank of Italy lacked independence and the ERM was still not credible, monetary growth was highly unstable and was the main determinant of Italian inflation, although oil price and tax shocks also played a role. After the March 1983 general exchange rate realignment and the French U-turn, the ERM became more credible and monetary growth stopped being a significant determinant of inflation; instead, the German inflation became the main variable influencing Italian inflation.     

Re‐Examining the Role of Structural Change and Nonlinearities in a Phillips Curve Model for South Africa

Although studies generally find evidence of a Phillips curve‐type relationship in South Africa, uncertainty remains about the relevance of the model over a relatively long sample period, and whether conventional output gap measures are suitable proxies for demand pressure. This paper reviews research which shows that the Phillips curve model prevails over an extended sample, provided that the benchmark specifications include major structural changes in the balance‐of‐payments and labour market, and account for shifts in the root causes of inflation. When this is done, a linear specification with an output gap in levels correctly predicts the non‐trended inflation pattern over the period 1971(Q1)–1984(Q4), whereas a piecewise concave curve with an output gap in growth rates accurately forecasts the decelerating inflation pattern during 1986(Q1)–2001(Q2). A novel feature of the concave model is that it remains statistically robust and structurally stable when it is estimated until 2015(Q4). The concave model imparts a disinflationary bias, which suggests that monetary policy should be more expansionary during downswing phases of the business cycle and neutral during upswing phases. The analysis also considers how the shape of the Phillips curve might change if the balance‐of‐payments constraint on demand is relaxed in a significant way.     

Causes of Inflation in China： Inflation Expectations

This paper argues that the main causes of inflation in China since the early 21st century are changes in the public's inflation expectations. The conventional wisdom, the quantity theory of money, may not be adequate to capture the relationship between price changes and money supply growth, as the economic system evolves and people's income and wealth grow. An examination of China's GDP deflator and broad money supply relative to nominal GDP shows that the relationship between the two series is relatively weak. A further examination of China's monthly CPI series over the period 2001–2010 reveals that the autoregressive models are a better fit than the moving average models, which suggests that the role of CPI expectations has been significant and important. Because of the importance of inflation expectations in CPI movement, we believe the Central Bank's monetary policy that targets CPI inflation should emphasize the use of policy instruments that have direct and strong communication links with the public. Quantitative measures would have their own use, but their effectiveness would be unlikely to match that of interest rate measures, especially from a short‐term perspective.     

What Causes China＇s High Inflation？ A Threshold Structural Vector Autoregression Analysis

China＇s astonishing economic growth implies a necessity to understand its inflation. The present paper employs threshold nonrecursive structural vector autoregression analysis to explore the asymmetric effects of macro-variables on inflation in low and high inflation regimes. The empirical evidence demonstrates, first, that the reactions of inflation to various shocks are inflation-regime-dependent and asymmetric. Second, monetary policy influences China ＂s high inflation and adjusting the domestic interest rate in China may be an effective way to control inflation in a high inflation regime, but not in a low inflation regime. In a high inflation regime, a high inflation rate may cause the macro-policy authorities to increase the domestic interest rate, in an attempt to stabilize high inflation. Third, contrary to expectations, the world oil price is not a strong cost-push factor in a low inflation regime. Oil price increases may increase inflation in a high inflation regime, but there is no such obvious effect in a low inflation regime. Finally, China ＂s nominal effective exchange rate influences inflation in both low and high inflation regimes. A nominal effeetive exchange rate appreciation might be effective in controlling domestic inflation in both regimes.     

Inflation targeting in Indonesia, 1999–2012: an ex-post review

Around the end of 1999, Bank Indonesia (BI) adopted inflation targeting as part of its approach to monetary policy. This article reviews the experience up to 2012, examines BI's performance in hitting its inflation targets and considers certain broader indicators of success. Overall, inflation targeting in Indonesia has been a messy, evolutionary process, and BI's implementation record compares unfavourably with that of its peers. Yet Indonesia recorded a significant downward trend in inflation during this period and maintained strong economic growth. Also, almost all of its inflation-targeting arrangements are now in line with common international practice. Looking ahead, this article offers suggestions for sustaining progress in inflation targeting, such as setting more ambitious targets in the outer years and implementing strong policies to reduce inflation further, including after large administrative price shocks.

The case for price level or inflation targeting—What happened to monetary policy effectiveness during the Japanese disinflation?

This paper examines whether price level or inflation targeting would have been appropriate policy choices for Japan during its disinflation and deflation period. We employ Markov switching and structural vector autoregressions, together with structural IS equations, to investigate monetary policy effectiveness during the Japanese disinflation. We find evidence of regime switching in the mid-1990s in a model including the nominal policy interest rate. When monetary policy shocks are identified by using the McCallum rule for monetary base, a monetary expansion is found to have a statistically significant impact on prices. Moreover, a lower real ex ante interest rate can still stimulate the economy despite the zero lower bound on nominal interest rates.     

地方政府赤字财政下的物价控制与货币政策选择

货币经济学的一个基本观点就是,紧缩的货币政策能够降低通货膨胀,而扩张性的货币政策能够导致通货膨胀。费德斯坦指出,没有充分考虑财政政策的影响,这是货币经济学的严重缺陷。因此,文章结合我国当前的财政政策,探讨了在地方政府赤字财政下,中央银行如何控制和治理通货膨胀。文章认为,在地方政府赤字财政下,如果政府通过银行融资具有优先权的话,紧缩的货币政策不仅不能够控制通货膨胀,反而加速了通货膨胀。     

Will the Sarb always Succeed in Fighting Inflation with Contractionary Policy?

The conventional view is that a monetary policy shock has both supply‐side and demand‐side effects, at least in the short run. Barth and Ramey show that the supply‐side effect of a monetary policy shock may be greater than the demand‐side effect. We argue that it is crucial for monetary authorities to understand whether an increase in expected future inflation is due to supply shocks or demand shocks before applying contractionary policy to forestall inflation. We estimate a standard New Keynesian dynamic stochastic general equilibrium model with the cost channel of monetary policy for the South African economy to show that whether the South African Reserve Bank should apply contractionary policy to fight inflation depends critically on the nature of the disturbance. If an increase in expected future inflation is mainly due to supply shocks, the South African Reserve Bank should not apply contractionary policy to fight inflation, as this would lead to a persistent increase in inflation and a greater loss in output. Our estimation results also show that with a moderate level of cost‐channel effect and nominal rigidities, a New Keynesian dynamic stochastic general equilibrium model with the cost channel of monetary policy is able to mimic the price puzzle produced by an estimated vector autoregressive model.     

Mix of Fiscal and Monetary Policy Rules and Inflation Dynamics in China

The present paper examines the role of the mix of fiscal and monetary policy rules in determining inflation dynamics using fiscal and monetary policy reaction functions and Markov‐switching vector autoregression methods based on quarterly data in the period 1992–2007. Our results show that fiscal and monetary policies in China can be adequately described using some simple rules, and that significant regime shifts took place around 1998. Fiscal policy tended to be active and countercyclical in the pre‐1998 period, then switched to be passive and more countercyclical, whereas monetary policy was characterized as passive and procyclical in the pre‐1998 period, and switched to be active and countercyclical afterwards. The mix of fiscal and monetary policy rules can explain inflation dynamics better than the monetary policy rule alone. Therefore, price stability requires not only appropriate monetary policy but also appropriate fiscal policy.     

Reactions to Shocks and Monetary Policy Regimes: Inflation Targeting Versus Flexible Currency Board in Sub‐Saharan Africa

The paper examines the monetary policy actions through which central banks in sub‐Saharan Africa have tried to eliminate the negative impacts of the shocks facing their economies. We compare two different monetary policy regimes: a currency board regime (in the CFA zone) and an inflation targeting policy regime (Ghana and South Africa) when central banks respond to demand, supply, and fiscal shocks. We extend the usual forecasting and policy analysis system models to replicate the economic features of these economies during the period 2002–12 and to evaluate the impact of several policies in response to these shocks. We find that both policies are inappropriate in helping the economies escape from the effects of negative demand shocks, both are essential when negative shocks to primary balance occur, while inflation targeting dominates the currency board regime as a strategy to cope with positive shocks to inflation.     

Dynamics of Money Market Interest Rates in Ghana: Time-Frequency Analysis of Volatility Spillovers

As the second longest practicing inflation targeting economy in Africa, it is of interest to investigate the degree to which policy interest rate influences other money market rates so as to gauge the overall effectiveness of monetary policy transmission in Ghana. This study evaluates the degree of connectedness among money market rates and also determines the most dominant money market rate(s) in Ghana. The basic finding is that the monetary policy rate has a low-to-moderate influence on volatility dynamics of other money market rates in Ghana across historical time-interval and time-frequency domains. This is a reflection of a generally weak capability of policy interest rate to drive other market rates in Ghana. Both monetary policy rate and Treasury bill rate are net transmitters of shocks, while interbank, lending and saving rates are net receivers of shocks in the money market. However, the Treasury bill emerges as the largest shock transmitter in the money market, across all forecast horizons and analytical domains. The lending rate is the largest shock recipient in the money market, largely from the Treasury bill rate which suggests ample evidence of fiscal dominance in Ghana. The study accentuates the exigency for monetary and fiscal policies to expeditiously address the domestic structural bottlenecks, especially in the financial sector and the fragile fiscal profile, in order to strengthen policy transmission in Ghana.     

The Impact of Inflation Uncertainty on Output Growth and Inflation in Thailand*

We explore the impact of inflation uncertainty on output growth in Thailand, an emerging market economy with moderate inflation. Inflation and output uncertainty are modeled in a bivariate constant conditional correlation generalized autoregressive conditional heteroskedastic (AR(p)‐cccGARCH(1,1)) specification. We include the exchange rate in the mean equations, and use the headline and core inflation rates and industrial production to generate inflation and output uncertainty series. These series are then used in Granger causality tests to make inferences about the effect of monetary policy‐induced inflation uncertainty. Causality tests show a positive relation from inflation to inflation uncertainty. Additionally, increased inflation uncertainty decreases output. These results are consistent with real costs associated with moderate inflation. Finally, we find no evidence that monetary policy reduced these costs.

通胀率动态与通胀惯性度量

本文从通胀惯性的理论模型出发,构建无限状态Markov区制转移的计量模型,实现对通胀惯性的有效度量。对美国通胀惯性的实证分析,证实货币政策工具的频繁使用会付出通胀惯性的代价,暴露出其单一目标货币政策框架的缺陷。我国央行的调控也已经对市场利率形成了显著的传导作用,谨慎地使用货币政策工具,使我国的通胀惯性在被货币政策短暂影响后,得以有效恢复。这表明坚持实行多目标、多手段与宏观审慎政策相结合的调控模式,对维护经济环境稳定与长期发展的重要性。十国通胀惯性的度量结果与对比分析,进一步佐证了本文观点。
