Inflation Uncertainty and Monetary Policy in China

This paper uses a stochastic volatility model structural break tests with unknown point, and a counterfactual simulation method to discuss the significant decline in inflation uncertainty in China over 1978-2009. We attempt to quantify the contributions of better monetary policy and smaller structural shocks （including demand, supply and policy impacts） on the reduced inflation uncertainty. Empirical results in the present paper suggest that improved monetary policy accounts for only a small fraction of the reduction in inflation uncertainty from the pre-1997 period to the post-1997 period in China. The bulk of the significant moderation in inflation uncertainty arises from smaller shocks. This finding indicates that the quiescence of inflation in China over the past decade could well be followed by a return to a more turbulent inflation era. Therefore, the use of preemptive monetary policy to anchor inflationary expectations and keep moderate inflation uncertainty is warranted.     

Monetary Aggregates Targeting,Inflation Targeting and Inflation Stabilization in Ghana

The central bank of Ghana (BoG) has operated monetary aggregates targeting and inflation targeting since the 1980s, to ensure enhanced output growth, low unemployment and stable, low inflation. Under inflation targeting, the inflation rate averaged 13.26 per cent per annum between 2007 and 2015, compared with 29.22 per cent per annum under monetary aggregates targeting. The relatively lower inflation rates notwithstanding, an average inflation rate of 13.2 per cent per annum is far above the medium‐term target of 8 per cent. This paper has examined the effectiveness of monetary aggregates targeting and inflation targeting in keeping inflation at moderate levels. The autoregressive distributed lag (ARDL) model was applied to the data covering the period 1970–2015. The results show that monetary targeting has steered inflation to moderate levels only in the short run while inflation targeting has maintained low inflation rates in both short run and long run. But neither regime has kept inflation at stable levels and within the target band, due to the sluggish transmission of broad money supply and prime rate changes to inflation. We implore the monetary authorities to strengthen the institutional setup for steering short‐term interest rates in Ghana. They should also enhance the BoG Act 2002 (Act 612), to develop secondary anchors and rules around output, money supply and fiscal deficit. Finally, the monetary policy committee should monetary policy credibility and transparency through strengthening its communication framework.     

Monetary Policy Uncertainty and Inflation: The Role of Central Bank Accountability

We analyse the issue of central bank accountability with the aid of a simple monetary policy game with uncertainty about the agent's inflation stabilisation preferences. We find that there may be an important economic role for accountability in addition to its political function of making the central bank answerable to voters through its accountability to the executive. The model suggests that for countries with relatively little central bank independence, or perhaps a poor inflationary track record, significant reductions in inflation can be achieved by lowering monetary policy uncertainty. These reductions are much smaller for inflation-averse central banks, when monetary policy uncertainty is reduced by the same absolute amount. Thus, the effectiveness of accountability – as a means of lowering both inflation and inflation uncertainty – is higher the lower the degree of central bank conservativeness.     

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.     

On the Sources of Inflation in Kenya: A Model‐Based Approach

We develop a semi‐structural new‐Keynesian open‐economy model – with separate food and non‐food inflation dynamics to study the sources of inflation in Kenya in recent years. To do so, we filter international and Kenyan data (on output, inflation and its components, exchange rates and interest rates) through the model to recover a model‐based decomposition of most variables into trends (or potential values) and temporary movements (or gaps) – including for the international and domestic relative price of food. We use the filtration exercise to recover the sequence of domestic and foreign macroeconomic shocks that account for business cycle dynamics in Kenya over the last few years, with a special emphasis on the various factors (international food prices, monetary policy) driving inflation. We find that while imported food price shocks have been an important source of inflation, both in 2008 and more recently, accommodating monetary policy has also played a role, most notably through its effect on the nominal exchange rate. We also discuss the implications of this exercise for the use of model‐based monetary policy analysis in sub‐Saharan African countries.     

Does Money Have a Role in Monetary Policy for Price Stability under Inflation Targeting in Thailand?

This paper deploys Thai quarterly data for the study period 1999q1–2014q4 to econometrically investigate the proposition that money growth is an important, if not the sole, determinant of inflation under inflation targeting and that the money growth-inflation relation is not conditional on the stability of the money-demand function. The autoregressive distributed-lag (ARDL) bounds-testing results suggest that, across the study period, the Thai money stock (narrow or broad), real output, prices, interest rates and exchange rates maintained a long-run equilibrium relationship. The associated error-correction model of inflation confirms the cointegral relationship among money (narrow or broad), real output, prices, interest rates and exchange rates. It also suggests that money growth has a significant distributed-lag impact on inflation. The presence of this money growth-inflation relationship was associated with a stable narrow money-demand function, whereas the broad money-demand function remained unstable. These results for the study period are consistent with the view that the causal relationship between money growth and inflation holds in Thailand under inflation targeting when the Bank of Thailand deploys a short-term policy interest rate, rather than a monetary aggregate, as the instrument of monetary policy and that this relationship is not conditional on the stability of the money-demand function.     

Inflation and inflation uncertainty in the ASEAN-5 economies

This study explores the linkage between inflation and inflation uncertainty in the ASEAN-5 countries over the period 1970:01–2007:12. Inflation uncertainty is estimated as a conditional variance in an AR(p)-EGARCH(1,1) model. Granger causality tests show that rising inflation increases inflation uncertainty and that rising inflation uncertainty increases inflation in all five countries. The ASEAN-5 have had low inflation rates relative to other emerging markets. Thus, our study shows that even in low inflation emerging markets inflation can lead to inflation uncertainty and uncertainty can lead to inflation. Given current inflationary pressures in these countries, our results warn of possible costs of not keeping inflation in check.

Performance of Core Inflation Measures

This paper assesses the performance of core inflation measures based on the structural VAR approach. Since core or monetary inflation is not directly observable, we develop a monetary general equilibrium model that fits real aggregated European data and we use this model to generate time series for headline as well as core inflation. For five different schemes which attempt to identify core inflation within a VAR framework it is investigated whether the estimated core inflation series recover the true series sufficiently precise in order to be useful for monetary policy.     

Evidence on the Effects of Money Growth on Inflation with Regime Switching

Since the latter half of 2010, a new round of inflation has gradually been manifesting in China. The debate regarding whether excess money supply is responsible for this inflation has attracted scholars to investigate the effects of money growth on inflation. In this paper, we use correlation analysis to confirm the comovement between growth of monetary aggregates and inflation. We explore the asymmetric effects of monetary policy on inflation using the Markov regime‐switching model. The empirical results show that monetary policy can be more effective in curbing inflation in a high inflation state than in boosting the price level in a low inflation state. However, simply tightening the money supply might not be sufficient to suppress the price level. To this end, the Chinese Government should adopt other policies, such as supply stabilization policies, to help suppress the price level. Our study can help policy‐makers to determine the actual economic state and provides some policy implications for the current inflation.

Inflation and inflation uncertainty: The case of Cambodia,Lao PDR,and Vietnam

This paper studies the relationship between inflation and inflation uncertainty in Cambodia, Lao PDR, and Vietnam. Inflation uncertainty is estimated as the conditional variance in a family of generalized autoregressive heteroskedasticity (GARCH) models. This paper finds that inflation causes inflation uncertainty in these countries, which supports the argument of Friedman (1977). Moreover, the analysis demonstrates that inflation uncertainty causes inflation only in Lao PDR, which implies that Cukierman and Meltzer's (1986) argument can be supported in Lao PDR. This paper also investigates how inflation in the United States is related to inflation and inflation uncertainty in Indochina countries. The result shows that inflation positively responds to US inflation only in Cambodia.     

How should Central Banks Respond to Non-neutral Inflation Expectations?

This paper investigates the net real inflation effect on output in ten countries, comprising both advanced and developing countries. An indicator is introduced to compute the net inflation effect on output (NIEO) based on the difference between two concepts of core inflation, where both are computed using the decomposition of VAR residuals. We find that for all countries, when inflation is increasing the NIEO is significantly positive and is negative during periods of decreasing inflation. Typically, countries which follow anti-inflationary policies if the NIEO is of small magnitude suffer relatively minimal damage in output, whereas if the same policies are undertaken when the NIEO is large the damaging effects on output could be much greater. This suggests that the NIEO could be a useful indicator of the likely effects of policy, especially for countries which have frequent episodes of high inflation, and in those countries which employ inflation-targeting policy, as the timing of monetary policy actions could be optimized to take account of this real effect of inflation.     

Revisiting the Exchange Rate Pass‐Through to Inflation in Africa’s Two Largest Economies: Nigeria and South Africa

This paper revisits the exchange rate pass‐through (ERPT) to inflation in Nigeria and South Africa by incorporating structural breaks and using time series variables, namely the consumer price index, nominal effective exchange rate, gross domestic product, and crude oil price. Based on the Maki cointegration test and a flexible estimation approach of the Autoregressive Distributed Lag (ARDL) model, our empirical evidence suggests that the long‐ and short‐run ERPT to inflation is complete for Nigeria, while for South Africa it is incomplete both in the long run and short run. This result indicates that prices are stickier in South Africa compared to Nigeria. The comparison between Nigeria and South Africa confirms the role of inflation targeting and central bank credibility on the ERPT. The results divulge further that output growth in Nigeria increases inflation in the long run while it is anti‐inflationary in the short run. For South Africa, the effect of output growth is negatively insignificant. In addition, the long‐run effect of oil price is negative and significant for Nigeria, while for South Africa the short‐run effect of oil price is positive and significant. Therefore, the findings of this paper will assist the monetary authorities to achieve monetary policy objectives.     

Economic Globalization and Inflation in China: A Multivariate Approach

This paper evaluates whether globalization has increased the role of global factors in driving inflation in China. Unlike other published studies on the relationship between globalization and inflation, which mostly use Phillips curve models, this paper uses multivariate dynamic models to examine the dynamic interactions between globalization and inflation in China. Empirical results with quarterly data spanning from 1995 to 2012 show that the global output gap significantly affects the dynamics of inflation in China. In particular, the global output gap is superior to the domestic output gap in predicting domestic inflation. Impulse response and variance decomposition analyses reinforce this finding. Our results indicate that the central bank of China should take developments in global output into account in its monetary policy‐making process.

On Determinacy and Learnability in a New Keynesian Model with Unemployment

We analyse determinacy and stability under learning (E‐stability) of rational expectations equilibria in a new Keynesian model of inflation and unemployment, where labour market frictions due to costs of hiring workers play an important role. We derive results for alternative specifications of monetary policy rules and alternative values of hiring costs as a percentage of gross domestic product. We find that in general the region of indeterminacy and E‐instability in the policy space increases with hiring costs. Thus, higher hiring costs – consistent with European and South African “sclerotic” labour market institutions – seem to play an important part in explaining inflation and unemployment instability. Moreover, under lagged data‐based rules, the area where monetary policy delivers both determinacy and E‐stability shrinks. These rules also perform worse according to these two dimensions when hiring costs go up. Finally, under expectations‐based rules an additional explosive region is introduced. For South Africa, a rule based on current data – not unlike the original Taylor rule – works better than a forward‐looking rule.     

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.
