Terms of Trade Shocks and Inflation Targeting in Emerging Market Economies

Emerging market economies (EMEs) have persistently experienced different waves of commodity terms of trade disturbances, generating macroeconomic instabilities. The adoption of inflation targeting (IT) by many EMEs has raised questions about its relative suitability in dealing with these shocks compared with other monetary policy regimes. This paper tests the robustness of IT compared with monetary targeting and exchange rate targeting regimes in coping with commodity terms of trade shocks using the panel vector autoregressive technique. The results show that in general, IT countries respond better to commodity terms of trade shocks especially with respect to inflation and output gap. However, exchange rates are more volatile in IT countries than in exchange rate targeting countries. The results suggest that EME countries can reduce the adverse effects of commodity terms of trade fluctuations when they adopt IT, but they also need to pay attention to exchange rate movements.     

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.     

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.     

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.     

Structural Reform and Transparency in a Monetary Union

We assess how central bank transparency affects the incentives for labour market reform in a monetary union. We introduce transparency as affecting unemployment forecasts that provide information that the central bank has to the private sector and the governments. Under conditions of monetary policy opaqueness and inflation bias, we show that monetary union may induce more reform (as governments mitigate inflation surprises under idiosyncratic shocks), albeit to a lesser extent when inflation bias is only present at the national level. In the absence of inflation bias, central bank transparency, by eliminating inflation surprises in the face of idiosyncratic shocks, induces less reform in a currency union relative to monetary autonomy. Altogether, these results point to the need for a strong political commitment to reform so that member states benefit most from the combination of a credible and transparent single monetary policy with measures aimed at improving competitiveness and enhancing long-term growth.     

The macroeconomic effects of monetary policy: Evidence from Japan

This study examines the macroeconomic effects of monetary policy in Japan. We apply the new identification strategy proposed by Bu et al. (2021) to the Japanese case and estimate monetary policy shocks that bridge periods of conventional and unconventional monetary policymaking. We show the macroeconomic effects of monetary policy; a contractionary monetary policy shock significantly decreases output and inflation rates even under the effective lower bound. However, because the shorter-term and longer-term nominal interest rates are already close to zero, the magnitude of monetary policy shocks on the macroeconomic variables is modest.     

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.

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.     

Inflation targeting in India: A comparison with the multiple indicator approach

The empirical literature on identification and measurement of the impact of monetary policy shocks on the real side of the economy is fairly comprehensive for developed economies, but very limited for emerging and transition economies. In this study, we propose an identification scheme for a developing economy (taking India as a case study), which is able to capture the monetary transmission mechanism for that economy without giving rise to empirical anomalies. Using a VAR approach with recursive contemporaneous restrictions, we identify monetary policy shocks by modelling the reaction function of the central bank and structure of that economy. The effect of monetary policy shocks on the exchange rate and other macroeconomic variables is consistent with the predictions of a broad set of theoretical models. This set-up is used to build a hypothetical case of inflation targeting where the monetary policy instrument is set after assessing the current values of inflation only. This is in contrast with the ‘multiple indicator approach’ currently followed by the Reserve Bank of India (RBI). The results in this study suggest that the demand effects of interest rate are stronger than the exchange rate effects. There is also evidence of the mitigation of potential conflict between exchange rate and interest rate, one of main monetary policy dilemmas of the RBI in inflation targeting.     

Determinants of households’ inflation expectations in Japan and the United States

Using a VAR model that includes survey data on households’ inflation expectations for Japan and the US, we investigate their determinants and influences on the economy and compare their properties in two countries. Short-term non-recursive restrictions are imposed taking account of simultaneous co-dependence between realized and expected inflation. We find that responding to changes in exogenous prices and to monetary policy shocks, inflation expectations adjust more quickly than does realized inflation. Compared with Japan, the effects of exogenous prices on inflation and inflation expectations in the US are not only large but also long lasting and shocks to expectations have self-fulfilling effects on inflation.     

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.     

Global food prices and monetary policy in an emerging market economy: The case of India

This paper investigates a perception in the political debates as to what extent poor countries are affected by price movements in the global commodity markets. To test this perception, we use the case of India to establish in a standard SVAR model that global food prices influence aggregate prices and food prices in India. To further analyze these empirical results, we specify a small open economy New-Keynesian model including oil and food prices and estimate it using observed data over the period 1996Q2 to 2013Q2 by applying Bayesian estimation techniques. The results suggest that a big part of the variation in inflation in India is due to cost-push shocks and, mainly during the years 2008 and 2010, also to global food price shocks, after having controlled for exogenous rainfall shocks. We conclude that the inflationary supply shocks (cost-push, oil price, domestic food price and global food price shocks) are important contributors to inflation in India. Since the monetary authority responds to these supply shocks with a higher interest rate which tends to slow growth, this raises concerns about how such output losses can be prevented by reducing exposure to commodity price shocks.     

Price Stability and the Case for Flexible Exchange Rates

We revisit Friedman’s case for flexible exchange rates in a small open economy with several distortions and rigidities and a variety of domestic and external shocks. We find that, for external shocks, the flexible exchange rate regime outperforms the fixed regime independent of the source of domestic nominal rigidities provided that the monetary authorities pursue a policy of strict inflation targeting. For domestic supply shocks, a joint policy of a flexible exchange rate and strict inflation targeting fares well when the main source of nominal rigidities is in the domestic goods markets, but not if rigidities arise in the labor markets.     

The effectiveness of monetary policy in China: Evidence from a Qual VAR

Analyzing monetary policy in China is not straightforward because the People's Bank of China (PBoC) implements policy by using more than one instrument. In this paper we use a Qual VAR, a conventional VAR system augmented with binary policy announcements, to extract a latent indicator of tightening and easing pressure, respectively, for China. The model acknowledges that policy announcements are endogenous and summarizes policy by a single indicator. The Qual VAR allows us to study the impact of monetary policy in terms of unexpected changes in these latent variables, which we identify using sign restrictions. We show that the transmission of monetary policy impulses to the rest of the economy is similar to the transmission process in advanced economies in terms of both output growth and inflation despite a very different monetary policy framework. We find that bank loans are not sensitive to policy changes, which implies that window guidance is still a necessary policy tool. We also find that the impact of monetary policy shocks is asymmetric in terms of asset prices, that is, the asset price reactions differ in their sensitivity to tightening shocks and easing shocks, respectively. In particular, an easing of monetary conditions boosts stock prices while a tightening shock leaves stock prices unaffected. This shows that monetary policy is not a suitable tool to stabilize asset prices, which raises implications for financial stability and macroprudential policy.     

Monetary Policy and Risk-Based Asset Allocation

This paper focuses on the effects of the Fed’s monetary policy on stock and bond returns co-movement and their implications to risk-based asset allocation. Using a regime-switching model that controls for the economic effects of monetary policy we identify three co-movement regimes. We document that risk-based portfolio strategies poorly perform in the low correlation regime which features inflation shocks. We find outperformance evidence under the negative correlation regime with a high stock market risk and a very accommodating Fed policy. Less effectiveness is demonstrated under the positive correlation regime where bonds are regarded as risky assets and interest rate volatility is fueled by monetary policy.     

Deep habits and the dynamic effects of monetary policy shocks

We introduce deep habits into a sticky-price sticky-wage economy and examine the resulting models ability to account for the impact of monetary policy shocks. The deep habits mechanism gives rise to countercyclical markup movements even when prices are flexible and interacts with nominal rigidities in interesting ways. Key parameters are estimated using a limited information approach. The deep habits model can account very precisely for the persistent impact of monetary policy shocks on aggregate consumption and for both the price puzzle and inflation persistence. A key insight is that the deep habits mechanism and nominal rigidities are complementary: the deep habits model can account for the dynamic effects of monetary policy shock at low to moderate levels of nominal rigidities. The results are shown to be stable over time and not caused by monetary policy changes.     

A nonlinear ARDL model of inflation dynamics in the Philippine economy

This study investigated whether global oil price changes, exchange rate, interest rate, and economic output exert symmetric or asymmetric pass-through effects on inflation in the Philippines. A Nonlinear Autoregressive Distributed Lag (NARDL) model was fitted to the observable data using quarterly observations from 1998 to 2019. Knowledge of these relationships is important in monetary policy setting in achieving targeted inflation; the Philippines adopted inflation targeting in 2002. The finding shows that world oil price shocks are still prominent and the most important determinants of inflation variations in the country. There is prima facie evidence on the short-run asymmetry of oil price changes to inflation. Exchange rate pass-through to inflation was very minimal in the short-run, and there is no long-run effect. Evidence that interest rate and demand shocks have a long-run asymmetric effect on inflation was found. These findings imply that monetary policy setting should account for the asymmetric effects of inflation determinants. Study results provide a deeper understanding of how positive and negative changes of inflation determinants affect actual inflation, which aids policymakers in achieving targeted inflation.     

A Model for Monetary Policy Analysis for Sub-Saharan Africa

We develop a small open economy DSGE model usable for monetary policy in Sub-Saharan Africa. In this paper we apply the model to quarterly data from Ghana from 1981–2007. We find that permanent, but not transitory, technology shocks are the most important source of fluctuations. We find that the estimated monetary policy rule suggests that policy is aimed almost exclusively at fluctuations in output and ignores inflation, imports and exports. A negative result is that there appears to be significant issues in identifying some important parameters.     

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.
