Oil shocks and monetary policy rules in emerging economies

We examine the effects of shocks in the oil market on key macroeconomic variables in small open economies using a dynamic stochastic general equilibrium model with sticky prices and imperfect competition under different monetary policy rules. The numerical solutions show that the types of exchange rate regimes and monetary policies could partly explain the trends in macroeconomic volatilities considering negative shocks to oil supply (Hamilton, 1983) and positive shocks to oil demand (Kilian, 2009). These findings are confirmed in vector autoregressive responses for Chile and Israel with inflation targeting under flexible exchange regimes and Hong Kong with fixed regime.     

The impact of inflation targeting: Testing the good luck hypothesis

Starting in the mid‐1980s, the level and volatility of inflation decreased across industrial countries. The inflation stabilization can be explained by a shift in monetary policy or by a lucky period of low volatility in business cycle shocks. To test the “good luck hypothesis,” we examine the inflation experience of Canada, one of the earliest and most successful adopters of an inflation targeting monetary policy. We Kalman‐filter the historical structural shocks consistent with an estimated dynamic stochastic general equilibrium (DSGE) model of the Canadian economy. The estimated shocks are used to build counterfactual histories. The good luck hypothesis can explain only a minor portion of the change in the path and volatility of inflation after the shift in policy. Most of inflation and output stabilization is accounted by the impact on expectations. Unconditionally, the inflation targeting policy does not improve on the previous policy in terms of inflation volatility, but supports a more favourable trade‐off, reducing substantially output volatility.     

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.     

Macroeconomic dynamics in Macedonia and Slovakia: Structural estimation and comparison

This paper estimates a structural macroeconomic model using data for Macedonia and Slovakia to characterize possible challenges Macedonia can face concerning macroeconomic stabilization during its transition process. A comparison of the estimated model parameters suggests that, in Slovakia, the output gap is less sensitive to real interest rate movements and prices experience greater inertia. The estimated monetary policy reaction functions show Macedonia and Slovakia as inflation targeters, with Macedonia as the more conservative one, despite its officially applied exchange rate targeting regime. The differences in the estimated parameters imply differing transmission mechanisms for Macedonia and Slovakia. Consequently, the variance of domestic variables in Slovakia is most influenced by monetary policy shocks, while there is no single dominating shock explaining the volatility of Macedonia's macroeconomic variables. The exchange rate shock, the monetary policy shock and the demand shock are jointly important in determining the volatility of Macedonia's variables. The model simulations indicate that Macedonia experiences lower output gap and inflation volatility than Slovakia. This comes, nevertheless, at the cost of higher interest rate and real exchange rate volatility in Macedonia, which could be an indication of more volatile financial markets with possible negative implications for financial stability.     

人民币汇率波动与货币政策调控难度

文章采用动态随机一般均衡（DSGE）模型研究了中国货币政策实施时不能忽略的人民币汇率波动特征。文章构建了人民币汇率波动与中国货币政策及其宏观经济系统影响机制的理论模型,并在模型参数校准的基础上进行了政策模拟。研究结果表明,较大的人民币汇率波动会在一定程度上减弱中国货币政策的调控效果,但是对每个变量冲击响应的影响程度有所不同。较大的人民币汇率波动将显著干扰货币政策对宏观经济需求的调控,人民币汇率升值波动幅度较大时,货币政策对需求变量的调控作用会减弱,但不会影响相关需求变量在不同时点的冲击响应走势特征。较大的汇率波动会减弱利率上行对出口的负面影响,有利于缓解货币政策对出口的负面冲击,但会导致贸易条件（出口价格和进口价格的比值）进一步恶化。     

Should Commodity Exporters Peg to the Export Price?

To account for the specific situation of commodity exporters, pegging to export prices (PEP) has been proposed elsewhere as an alternative to other conventional monetary regimes such as an exchange rate peg or inflation targeting. PEP is supposed to deliver automatic accommodation to terms‐of‐trade shocks, while retaining the credibility gain from a nominal anchor. This paper analyzes the PEP proposal in a dynamic general‐equilibrium model and compares it with a standard Taylor rule, consumer price index (CPI)‐level targeting and a nominal exchange rate peg. Judged by the degree of output stabilization, PEP performs very similar to CPI targeting for export demand as well as domestic demand shocks and underperforms in the case of shocks to the export price. The results suggest that PEP is not superior to conventional CPI targeting from a macroeconomic stabilization perspective.     

A general equilibrium open economy model for emerging markets: Monetary policy with a dualistic labor market

An optimizing model of a small open emerging market economy (SOEME) with dualistic labor markets and two types of consumers, delivers a tractable model for monetary policy. Differences between the SOEME and the SOE are derived. Parameters depend on features of the labor market and on consumption inequality, and affect the natural interest rate, terms of trade and potential output. The supply curve turns out to be flatter and more volatile, with a larger number of shift factors, including policy-determined terms of trade. A simple basic version of the model is simulated in order to compare different policy targets in response to a cost shock. Flexible domestic inflation targeting gives the lowest volatility although there are trade-offs. Exchange rate volatility is relatively lower but still makes a major contribution to controlling inflation. Flexible CPI inflation targeting performs better when combined with some kind of managed floating. Inflation targeting has to be flexible. With more backward-looking behavior the policy response to a shock is reduced.     

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.     

Modelling the impact of central bank intervention on exchange rate volatility under inflation targeting

This article empirically investigates the effect of central bank’s foreign exchange interventions on the level and volatility of the Uganda shilling/US dollar exchange rate (UGX/USD) under an inflation-targeting regime. Utilizing daily data spanning the period 1 September 2005, to 31 December 2015, we estimate a foreign exchange intervention model within a GARCH theoretic framework. Empirical results indicate that foreign exchange interventions have had mixed impact on the volatility of the exchange rate. We find that inflation targeting is capable of curbing temporary exchange rate shocks. Empirical results indicate that while order flow is capable of reducing exchange rate volatility, an increase in the operating target rate, the 7-day interbank rate tends to exacerbate exchange rate volatility. Our empirical results are robust to alternative model specifications. We argue that inflation targeting is an effective monetary policy tool for curbing exchange rate volatility.     

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.

The effect of a Chinese slowdown on inflation in the euro area and the United States

We investigate the effect of a Chinese slowdown on inflation in the euro area and the United States using the NiGEM multi-country model. We construct different scenarios including a fall in Chinese aggregate demand, a commodity price slump, financial market corrections and a devaluation of the renmimbi. While the commodity slump has the strongest impact on inflation, the demand and exchange rate shocks also play a role; on the contrary, financial turbulences have minor effects. Finally, we study the extent to which monetary policy in advanced economies can succeed in reflating the economy following such a Chinese slowdown. The room for central bank interventions is large.     

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.     

Macroeconomic transitions and the transmission mechanism: Evidence from Turkey

This paper investigates changes to the macroeconomic transmission mechanism in Turkey following a major reform of monetary policy in the early 2000s. We use a Threshold VAR (TVAR) framework to test for and then estimate a model with endogenous transitions between regimes. We detect two regimes, with a clear transition between them in 2003–4. The pre-reform regime is characterized by high inflation, passive monetary policy and persistent responses to shocks. The post-reform regime is characterized by low inflation, active and credible monetary policy and markedly less persistent responses to shocks. Using a model that contains sufficient variables to capture diverse transmission mechanisms, working through the real exchange rate, domestic credit and monetary policy, we find evidence of sharp changes in transmission mechanisms. Post-reform, the response of Turkey to macroeconomic shocks has changed to be similar to those in other modern, market-orientated economies.     

Exchange market pressure and primary commodity – exporting emerging markets

This paper studies short-term sensitivity between exchange market pressure and various domestic and external factors in primary commodity-exporting emerging markets. The paper focuses on the top country-commodity groups in sugar, cereal, fuels, ores and coffee during the pre-peak and post-peak commodity price periods across floating and pegged exchange rate regimes, using the price of crude oil as a general benchmark. Employing a panel model and panel VAR analysis, the paper finds the heterogeneity of response patterns unique to country-commodity groups and exchange rate regimes. According to the results, in flexible regimes, volatility occurs via the foreign exchange market, interest rates, and domestic credit cycles, feeding into the social costs for structurally weaker economies. Hard exchange-rate pegs often result in a drain on international reserves as the terms of trade deteriorate following post-price peaks, leading to unpopular depreciation. These results accentuate concerns over uneven international trade patterns, an open economy’s short-term foreign exchange policy, and speculative capital flows. Such sensitivity has broad implications for macroeconomic balance and the sustainability of implied exchange rate targets in the presence of a foreign exchange constraint across emerging markets.     

Inflation and Exchange Rate Targeting Challenges Under Fiscal Dominance

Countries have significantly increased their public-sector borrowing since the Global Financial Crisis. As a consequence, monetary authorities may face pressure to deviate from their policy targets in ways designed to ease the debt burden. In view of this consideration, we test for greater fiscal dominance over 2000-2017 under Inflation Targeting (IT) and non-IT regimes. We find that evidence of fiscal dominance varies across countries and debt configurations. Higher ratios of public debt-to-GDP may appear associated with lower policy interest rates in advanced economies. However, a declining natural rate of interest largely explains the pattern of lower rates and higher debt in these countries. The most robust evidence of fiscal dominance lies among emerging markets under non-IT regimes, composed mostly of exchange rate targeters. For these countries, policy interest rates are non-linearly associated with public debt levels, depending on both the level of hard-currency public debt-to-GDP and the currency composition of public debt. We also show that emerging market economies with greater exchange rate volatility, inflation volatility, and underlying commodity exposure exhibit stronger associations between public debt and policy interest rates.     

PRICE-BASED MEASUREMENT OF FINANCIAL GLOBALIZATION: A CROSS-COUNTRY STUDY OF INTEREST RATE PARITY

Abstract.   We characterize the relationship between ex post exchange rate depreciation and the interest differential for both developed and emerging market economies. The measured ex post uncovered interest differentials in terms of both levels and absolute values are then related to a set of variables that capture macroeconomic and policy conditions. We find that a wide diversity in the coefficient relating depreciations and interest differentials can be attributed to differences in inflation volatility, financial development, capital account openness, legal development and the nature of the exchange rate regimes. The robust results are mainly found in the emerging market country grouping.     

Monetary policy, oil shocks, and TFP: Accounting for the decline in US volatility

An equilibrium model is used to assess the quantitative importance of monetary policy for the post-1984 decline in US inflation and output volatility. The principal finding is that monetary policy played a substantial role in reducing inflation volatility, but a small role in reducing real output volatility. The model attributes much of the decline in real output volatility to smaller TFP shocks. We also investigate the pattern of output and inflation volatility under an optimal monetary policy counterfactual. We find that real output volatility would have been somewhat lower, and inflation volatility substantially lower, had monetary policy been set optimally.     

Exchange rate volatility and export performance: a cointegrated VAR approach

During the last decades Norwegian exporters have–despite various forms of exchange rate targeting–faced a rather volatile exchange rate which may have influenced their behaviour. Recently, the shift to inflation targeting and a freely floating exchange rate has brought about an even more volatile exchange rate. We examine the causal link between export performance and exchange rate volatility across different monetary policy regimes within the cointegrated Vector Autoregression (VAR) framework using the implied conditional variance from a Generalized Autoregressive Conditional Heteroskedasticity (GARCH) model as a measure of volatility. Although treating the volatility measure as either a stationary or a nonstationary variable in the VAR, we are not able to find any evidence suggesting that export performance has been significantly affected by exchange rate uncertainty. We find, however, that volatility changes proxied by blip dummies related to the monetary policy change from a fixed to a managed floating exchange rate and the Asian financial crises during the 1990s enter significantly in a dynamic model for export growth–in which the level of relative prices and world market demand together with the level of exports constitute a significant cointegration relationship. A forecasting exercise on the dynamic model rejects the hypothesis that increased exchange rate volatility in the wake of inflation targeting in the monetary policy has had a significant impact on export performance.     

Asymmetric effects of monetary policy shocks on economic performance: empirical evidence from Turkey

This study investigates the asymmetric effects of monetary policy shocks on the macroeconomic variables of exchange rate, output and inflation for an emerging economy ? Turkey ? by using monthly data between 1990 and 2014. We employ the innovative nonlinear vector autoregressive model of Kilian and Vigfusson (2011), which allows us to observe the effect of different stances (tight or loose) and different sizes (small or large) of monetary policy actions. Our empirical evidence reveals that tight monetary policy, which, in this case, is captured with a positive shock to interest rate, decreases exchange rate, output and prices, as economic theory suggests. Loose monetary policy, which is captured with a negative shock to interest rate, has the opposite effect on these variables. However, the effects of loose monetary policy are weaker than the effects of tight monetary policy because loose monetary policy shocks are less effective than tight monetary policy shocks. Moreover, as the magnitude of a shock increases, the difference between the effects of tight and loose monetary policy policies also increases.     

Identifying terms of trade shocks in a developing country using a sign restrictions approach

Using annual data for Botswana from 1960 to 2012, we examine the responses of macroeconomic variables to four generalized positive terms of trade shocks – global demand, globalizing, sector-specific and global supply. A sign-restricted structural vector autoregression model with a penalty function is estimated to identify the four possible shocks. While positive global demand and globalization shocks are both expansionary, they have opposite effects on inflation. A positive commodity market specific shock dampens real GDP growth and is inflationary, suggesting a possible Dutch disease response. A negative global supply shock suppresses both output growth and inflation. All but the last shock leads to a significant declining interest rate. Monetary policy contraction is recommended for the first shock and expansion for the others.
