通货膨胀目标制实践经验的国际考察

作为一种新型的货币政策制度框架,标准型通货膨胀目标制在全球的中央银行中已经获得了一定的认同.然而迄今为止,我们还缺乏一个对目前大量的通货膨胀目标制实践经验进行简洁而全面的概括,借以对货币政策的实践和通货膨胀目标钉住者的前景展望提供相应指南.而这种指南之所以必要,是因为队伍不断庞大的发展中国家和新兴市场经济体正在考虑是否采纳通货膨胀目标制.借鉴标准型通货膨胀目标制国家在控制通货膨胀过程中所积累的经验,探讨通货膨胀目标制国家面临的主要问题、发展趋势、政策实践,其目的是为了从国家的角度来思考是否应该采纳通货膨胀目标制;而对于已经实施通货膨胀目标制的国家,则要考虑如何健全这一制度框架.     

Monetary policy and commodity terms of trade shocks in emerging market economies

Commodity terms of trade shocks have continued to drive macroeconomic fluctuations in most emerging market economies. The volatility and persistence of these shocks have posed great challenges for monetary policy. This study employs a New Keynesian Dynamic Stochastic General Equilibrium (DSGE) model to evaluate the optimal monetary policy responses to commodity terms of trade shocks in commodity dependent emerging market economies. The model is calibrated to the South African economy. The study shows that CPI inflation targeting performs relatively better than exchange rate targeting and non-traded inflation targeting both in terms of reducing macroeconomic volatility and reducing the losses of a non-benevolent central bank. However, macroeconomic stabilisation comes at a cost of increased exchange rate volatility. The results suggest that the appropriate response to commodity induced exogenous shocks is to target CPI inflation.     

Exchange Rate Asymmetry and Flexible Exchange Rates under Inflation Targeting Regimes: Evidence from Four East and Southeast Asian Countries

While many have underscored the role of a flexible exchange rate policy under an inflation targeting (IT) regime, very few studies have examined what actually happens to exchange rate policy once the emerging market announces that it will adopt inflation targeting. The central contention of this paper is that while the adoption of an inflation targeting (IT) policy may lead to more flexible exchange rate movements, for various reasons it is possible that the degree of flexibility will be significantly higher on one side of the market. In this study, we demonstrate that four Asian economies—namely, Indonesia, Korea, the Philippines and Thailand—whom were among the first group of emerging markets to embrace the inflation targeting framework of monetary policy, tend to adopt a form of asymmetrical exchange rate behavior, wherein appreciation pressures are restrained more substantially than depreciation pressures.     

Inflation targeting regimes

This paper divides the monetary frameworks of countries that use an inflation target to define their monetary framework into three different regimes: (i) full-fledged inflation targeting, (ii) implicit price stability anchor, and (iii) inflation targeting lite. The regimes are differentiated by the clarity and credibility of the commitment to the inflation target. The revealed preference for different regimes is related empirically to cross-country structural differences in economic and financial development. Policy implications of moving from one regime to another are drawn, especially for emerging market countries aiming at full-fledged inflation targeting.     

Inflation targeting in emerging market and transition economies: Lessons after a decade

Starting in the early 1990s, several emerging market and transition economies adopted inflation targeting (IT). In this paper we discuss a number of issues that arise in this context: (a) the definition of IT, (b) the role of preconditions for IT, (c) the use of intermediate exchange rate targets, and (d) the specification of inflation targets. Our overall conclusion is that, suitably modified, IT is a useful policy strategy for EMEs.     

Inflation,openness, and exchange-rate regimes: The quest for short-term commitment

This paper further tests Romer's [Romer, D., 1993. Openness and inflation: theory and evidence. Quarterly Journal of Economics 58, 869–903] extension of Kydland and Prescott's [Kydland, F., Prescott, E., 1977. Rules rather than discretion: the inconsistency of optimal plans. Journal of Political Economy 85, 473–491] predictions for dynamic inconsistency problems in open economies. In a panel data set of developed and developing countries from 1973 to 1998, I find that openness does not play a role in restricting inflation in the short run. On the other hand, a fixed exchange-rate regime plays a significant role. The results are robust to controlling for other variables that determine inflation, performing sensitivity analysis, and using a de facto exchange-rate regime classification.     

How should emerging economies float their currencies?

Floating exchange rates seem to be gaining ground in Latin America, East Asia and the transition economies. The recent crises left many economies with no alternative but to float. Others have moved toward floating, searching for greater flexibility and insulation from external shocks. The question for most emerging market economies, then, is no longer to float or not to float, but how to float. Four issues arise in this regard. The first is how to float and have low inflation. The second is whether floating provides as much insulation as conventional theory predicts, especially in the presence of dollarized liabilities. Which leads to the third point: the relationship between the stability of the exchange rate and that of the financial system. The fourth is how to conduct monetary policy under a float, and the role of inflation targeting. We consider each of these points in turn, and conclude that a workable model of how to float seems to be emerging from the so‐far successful experience of countries like Chile and Brazil. It involves the adoption of an inflation target as the main anchor for monetary policy, coupled with a monetary policy reaction function that — aside from reacting to the output gap and other determinants of the inflation rate — reacts also partially to movements in the nominal exchange rate.

Inflation targeting in emerging economies: Panel evidence

This paper shows there is no evidence that the inflation targeting regime (IT) improves economic performance as measured by the behavior of inflation and output growth in developing countries. The control of common time effects results in less negative and less significant IT impacts on inflation, inflation volatility and output growth volatility than previously found in the literature. Additionally, our analysis shows robust evidence of lower output growth during IT adoption. On balance, although lower long-run mean inflation signals that the central banks of emerging economies with inflation targeting are more inflation-averse, the costs of disinflation have not been lower than under other monetary regimes.     

Forecasting South African inflation using non-linearmodels: a weighted loss-based evaluation

The conduct of inflation targeting is heavily dependent on accurate inflation forecasts. Non-linear models have increasingly featured, along with linear counterparts, in the forecasting literature. In this study, we focus on forecasting South African inflation by means of non-linear models and using a long historical dataset of seasonally adjusted monthly inflation rates spanning from 1921:02 to 2013:01. For an emerging market economy such as South Africa, non-linearities can be a salient feature of such long data, hence the relevance of evaluating non-linear models’ forecast performance. In the same vein, given the fact that 1969:10 marks the beginning of a protracted rising trend in South African inflation data, we estimate the models for an in-sample period of 1921:02–1966:09 and evaluate 1, 4, 12, and 24 step-ahead forecasts over an out-of-sample period of 1966:10–2013:01. In addition, using a weighted loss function specification, we evaluate the forecast performance of different non-linear models across various extreme economic environments and forecast horizons. In general, we find that no competing model consistently and significantly beats the LoLiMoT’s performance in forecasting South African inflation.     

A generalization of modern production theory

This paper analyses the relationship between inflation and equity returns in Australia over the period January 1974 to March 1996. Analysis is based on monthly and quarterly data, using value weighted equity indices at both the aggregate market and industry level. Three price indices, the consumer price index (CPI) (quarterly) and the manufactured materials used index (MMU) and the manufacturing articles produced index (MAP) (both monthly and quarterly) are used to measure inflation. Results provide little evidence of the statistically significant negative relationship observed in the US for the full study period. Analysis is also conducted on three subperiods, ‘monetary targeting’ (July 1976–January 1985), ‘checklist approach’ (February 1985–December 1989) and anti-inflation (January 1990–March 1996). At the market level the anti-inflation subperiod does provide some evidence of a negative relationship between inflation and equity returns though statistical significance is not apparent with quarterly time series. The impact of expected inflation on industry returns varies considerably. Consistent with the overall market analysis, the incidence of negative expected inflation betas increases in the latter anti-inflation subperiod. Finally, changes in Government inflation policy appear to have greatest impact on industrial company expected inflation betas.     

Destabilizing effects of a successful stabilization: a forward-looking explanation of the second Hungarian hyperinflation

Summary. The extreme severity of the second Hungarian hyperinflation is argued to be related to the unusual way in which the inflation was eventually stabilized. The historical features of this episode are represented in a general equilibrium model, which incorporates a transition from one monetary regime to another. During the inflation the government finances a fixed deficit with seigniorage revenue. After the stabilization the government budget is balanced and the central bank engages in a program of subsidized lending to the private sector. Stabilization is achieved by targeting a low inflation rate path through adjustments in the quantity of central bank lending. I show that under this stabilization policy (1) the dynamic equilibrium path of the economy is indeterminate and (2) arbitrarily high pre-stabilization inflation rates are possible.

Exchange Rate Passthrough Effects and Inflation Targeting in Emerging Economies: What is the Relationship?

Several studies have shown that over the past 10 years the passthrough effect from currency depreciation into domestic inflation has been decreasing in emerging economies that adopted inflation targeting (IT) during the mid and late 1990s. Therefore the nominal exchange rate effect on domestic inflation is becoming less of an issue for these countries. The literature has offered different explanations for these declines but so far they have not been directly related to the adoption of IT. This paper shows that lower passthrough effects can also be the result of the implementation of an IT regime and argues, contrary to previous studies, that the effects of the nominal exchange rate on inflation are still a relevant issue for emerging IT countries. The reason for this is that the empirical evidence offered for the lower passthrough misses the nature of the relationship between inflation and the nominal exchange rate under IT.     

Structural Changes and the Scope of Inflation Targeting in Korea *

A small, open macroeconomic model that accounts for new financial accelerator effects (the effects of fluctuations in asset prices on bank credit and economic activity) is developed to evaluate various policy rules for inflation targeting. Given the conditions of asset markets and the fragility of the financial sector, monetary policy responses can potentially amplify the financial accelerator effect. Simulations are used to compare various forms of inflation targeting using a model that emphasizes long-term inflation expectations, output changes, and the asset price channels. The simulations suggest that a successful outcome can be obtained by adhering to simple forward-looking rules, rather than backward-looking policy rules. Furthermore, inflation targeting can contribute to price as well as output stability by helping to keep the financial accelerator from being activated. Inflation targeting in emerging economies can provide an environment conducive to long-term capital market development. [E51,F3,F4]     

Financial distress and fiscal inflation

Is inflation ‘always and everywhere a monetary phenomenon’ or is it fundamentally a fiscal phenomenon? The answer hinges crucially on the underlying monetary–fiscal policy regime. Scant attention has been directed to the role of credit market frictions in discerning the policy regime, despite its growing importance in empirical macroeconomics. We augment a standard monetary model to incorporate fiscal details and credit market imperfections. These ingredients allow for both interpretations of the inflation process in a financially constrained environment. We find that introducing financial frictions to the model and adding financial variables to the dataset generate important identifying restrictions on the observed pattern between inflation and measures of financial and fiscal stress, to the extent that it overturns existing findings about which monetary–fiscal policy regime produced the U.S. data. To confront policy regime uncertainty, we propose the use of dynamic prediction pools and find strong cyclical patterns in the estimated historical regime weights.     

Unemployment–inflation trade-offs in OECD countries

Inflation and unemployment reduce welfare of individuals and should be as low as possible in any economy. Cointegration and Granger causality tests suggest that there are long run relations between these two variables among the OECD economies. While rates of unemployment vary significantly among these economies, rates of inflation have stabilised at lower rates as a result of inflation targeting policies adopted in them during the last two decades. The Phillips curve phenomena are still empirically significant for 28 out of 35 of these OECD economies in country specific regressions; in fixed and random effect panel data models and in a panel VAR model for 1990:1 to 2014:4. Country specific supply curves and Okun curves are consistent to thin Phillips curve relations. Leftward shifts in the Beveridge and Phillips curves require labour market reforms balancing between job creations and destructions. Complementing macro stimulations by microeconomic structural and institutional reforms can bring efficiency in bargaining for wages and employment among firms and workers to make unemployment–inflation trade-offs more significant and relevant in these economies.     

Has globalization shrunk manufacturing labor share in transition economies?

The objective of this paper is to investigate the nexus between the labor share and globalization in transition economies, with a reference to the skill intensity. We put these developments in the context of the structural and reform developments in transition economies. We rely on the predictions of the efficient bargaining model, whereby globalization forces are set to affect workers’ market bargaining power, which then produces certain developments in the labor share. We use industry-level data for 23 transition economies of Central and Southeast Europe and the Commonwealth of Independent States over the late transition period of 2000–2015. Results robustly suggest that globalization forces played important role for the stagnant labor shares in transition economies, mainly in low-skill industries. Workers’ shares in high-skill industries largely remained intact. Results further suggest that the negative effect has been the strongest for the low-skilled workers in the early transition phase and then lessened or vanished as countries turned a higher development stage. The key finding advises that if governments of transition countries attempted to or undertook steps to seize globalization by offering ‘cheap labor’, then it has been the wrong strategy.     

Monetary policy rules for financially vulnerable economies

One distinguishable characteristic of emerging market economies is that they are not financially robust. These economies are incapable of smoothing out large external shocks, as sudden capital outflows imply abrupt swings in the real exchange rate. Using a small open-economy model, this paper examines alternative monetary policy rules for economies with different degrees of liability dollarization. The paper answers the question of how efficient it is to use inflation targeting (IT) under high liability dollarization. Our findings suggest that it might be optimal to follow a nonlinear policy rule that defends the real exchange rate in a financially vulnerable economy.     

The role of monetary policy credibility in explaining the decline in exchange rate pass-through in South Africa

This paper investigates the key factors that explain the documented decline in the exchange rate pass-through in South Africa over the past two decades. The paper finds that this outcome is largely due to improved monetary policy credibility. The South African Reserve Bank has become more credible since the adoption of the inflation target regime through improved communication, transparency, and independence. We show that credibility is enhanced through a gradual disinflation process and reduction of inflation volatility. As result, expectations of agents have become well-anchored at levels that are consistent with its objectives of keeping inflation within the official target range of 3–6 percent even in the presence of external shocks. This in turn reduces the exchange rate pass-through. This finding is important from a monetary policy perspective not only for South Africa but other emerging economies such as Turkey as it shows that improving monetary policy credibility is a key ingredient to reducing exchange rate pass-through.     

NOMINAL GDP TARGETING AND CENTRAL BANK CONSERVATIVENESS

In the literature on monetary economics, there is the ‘inflationary bias’ result which predicts that the rate of inflation will be biased towards a higher level under discretionary monetary policy than under a rule‐based policy regime. It is established that a credible nominal target can eliminate this ‘inflationary bias’. In this paper, we examine the case of nominal GDP targeting, which is a rule‐based monetary regime. Depending on the degree of conservativeness by the central bank, we show in a stylized model the choice of different combination of inflation and real GDP targets can still result in an ‘inflationary bias’, and there also exists the possibility of a ‘dis‐inflationary bias’.
