Economic Liberalization and Conditional Volatility of Exchange Rate in Sub‐Saharan Africa: Asymmetric GARCH Analysis

Abstract: For small open economies, an understanding of movements in the exchange rate is imperative in analyzing trade and capital flows. In addition, reliable forecasting of exchange rate volatility is important in risk‐taking assessment and investment decision‐making, both of which are critical to long‐term growth. Using an asymmetric GARCH‐type approach, this paper examines the implications of economic liberalization on the stochastic behavior of the exchange rate series in a sample of sub‐Sahara African (SSA) countries over the 1970–2004 period. The results indicate that exchange rate volatility is variable, and is less volatile under fixed exchange rate regime (pre‐economic liberalization) and higher under flexible regime (post‐economic liberalization), that is, it is asymmetric. For most of the countries, the EGARCH and TGARCH models are robust to parameter stability and gives better forecasting performance compared to the standard GARCH model.     

The relationship between the monetary regime and output volatility: a multivariate GARCH-M model of the Japanese experience, 1919–1996

In this paper we tried to determine whether or not adherence to a floating exchange rate regime helped the Japanese economy to absorb shocks which originated from domestic and foreign sources based on the Japanese experience from the interwar to the post Bretton Woods floating exchange rate period. Using a multivariate GARCH-M model, we analyzed the relation of exchange rate volatility and output volatility directly. The results imply that the floating exchange rate regime has helped the Japanese economy to insulate itself from foreign shocks. The estimated coefficient which represents the response to the foreign shocks decreases and the decrease is significant in the floating exchange rate regime.     

What Drives Monetary Policy in Post-Crisis East Asia? Interest Rate or Exchange Rate Monetary Policy Rules

This paper estimates a simple small open macroeconomic model to analyse the effectiveness of monetary policy rules (MPRs) where either the nominal interest rate or the nominal exchange rate is the policy instrument. The aim is to ascertain which of those MPRs are best suited for a selection of inflation targeting economies of Asia. Normally, one would associate inflation targeting with interest rate rules but it is thought that, due to fear of floating, exchange rate rules may well be more effective given the openness of these economies. It is found that interest rate rules seem to better reflect the prevailing policy regime than exchange rate rules. It is also found that stronger relationships pertaining to the interest rate rules are found in the case of Korea and Thailand than for Indonesia and the Philippines. Exchange rates appear to be very influential in determining the value of the nominal interest rate but not in a policy sense.     

Monetary autonomy in selected Asian economies: The role of international reserves

With the increased financial integration of Asian countries, monetary policy takes on the additional role of maintaining the stability of the financial system along with the traditional objectives of promoting growth and employment with price stability. Given the importance and relevance of monetary policy in Asian countries, we examine monetary autonomy and its interaction with financial integration, currency regimes and international reserves for the past two decades in the following Asian countries: Thailand, Korea, Indonesia, the Philippines, and India. The empirical analysis reveals two significant and interesting findings that have policy implications. First, Thailand, Korea and Indonesia, countries that have moved towards a floating currency regime, experienced simultaneous declines in the sensitivity of their interest rates (thereby increasing monetary autonomy), while India continues to increase the sensitivity of its interest rates with a pegged exchange rate and increased financial integration. Second, in all of the studied economies, the accumulation of international reserves has contributed, to some extent, to the retention of monetary autonomy in terms of preventing the sensitivity of the interest rates from rising. We speculate that the accumulation of reserves plays the role of an anchor for monetary autonomy in emerging market economies facing a “fear of floating”.     

Surfing the waves of globalization: Asia and financial globalization in the context of the trilemma

Using the “trilemma indexes” developed by Aizenman et al. (2010) that measure the extent of achievement in each of the three policy goals in the trilemma—monetary independence, exchange rate stability, and financial openness—we examine how policy configurations affect macroeconomic performances, with focus on the Asian economies. We find that the three policy choices matter for output volatility and the medium-term level of inflation. Greater monetary independence is associated with lower output volatility while greater exchange rate stability implies greater output volatility, which can be mitigated if a country holds international reserves (IR) at a level higher than a threshold (about 20% of GDP). Greater monetary autonomy is associated with a higher level of inflation while greater exchange rate stability and greater financial openness could lower the inflation rate. We find that trilemma policy configurations affect output volatility through the investment or trade channel depending on the openness of the economies. Our results indicate that policy makers in a more open economy would prefer pursuing greater exchange rate stability while holding a massive amount of IR. Asian emerging market economies are found to be equipped with macroeconomic policy configurations that help the economies to dampen the volatility of the real exchange rate. These economies’ sizeable amount of IR holding appears to enhance the stabilizing effect of the trilemma policy choices, and this may help explain the recent phenomenal buildup of IR in the region.

A role model for China? Exchange rate flexibility and monetary policy in Japan

A substantial number of papers have proposed to allow for more exchange rate flexibility of the Chinese yuan. But few papers have tried to project how Chinese monetary policy will behave under flexible exchange rates. As Japan provides an important role model for China, this paper studies the role of the yen/dollar exchange rate for Japanese monetary policy after the shift of Japan from a fixed to a floating exchange rate regime. In contrast to prior studies, we allow for regime shifts in the impact of the exchange rate on monetary policy. The results show that the exchange rate had a substantial impact on Japanese monetary policy in periods of appreciation. This implies that repeated attempts to soften the appreciation pressure by interest rate cuts have led Japan into the liquidity trap. The economic policy conclusion for China is to keep the exchange rate pegged (to the dollar).     

“三元悖论”与人民币汇率制度选择

“三元悖论”从宏观上揭示货币政策独立性、汇率稳定、资本自由流动三大金融目标之间的相互制衡关系, 是汇率制度选择问题的一个基本理论分析工具。我国现行的汇率制度实质上是钉住美元的固定汇率制,在金融进一步开放的背景下,其弊端日益凸现,改革现行的汇率制度势在必行。我国现实经济条件决定了我国汇率制度改革的近期目标只能是建立汇率目标区,长期目标则是建立浮动汇率制。

The Relationship Between Price Stability and Financial Stability: Evidence From Major Emerging Economies

We examine the relationship between price stability and financial stability for major emerging economies using a Markov regime-switching model. Empirical results suggest that monetary policy is consistent with the Taylor rule in all countries except for India and all countries followed both low and high inflation targeting monetary policy regimes. Low inflation targeting regime seems to be more persistent and has higher duration than high inflation targeting regimes except for Indonesia and South Africa. All countries seem to have had financial stability concerns when they formulated their monetary policy as the coefficient of the financial stress index is statistically significant at least in one regime. Overall the results suggest that Taylor rule-based monetary policies have been implemented to various degrees in major emerging economies to achieve economic stability, price stability, and financial stability.     

新兴市场经济国家通货膨胀与汇率制度选择

本文利用23个新兴市场经济国家20年间的面板数据,对汇率制度和通货膨胀的关系进行实证研究,对我国汇率改革实践进行了考察。从我国的实际情况看,汇率波动的幅度越大则通胀率均值越大,2005年实行管理浮动以来我国通胀率处于明显的上升趋势。我国应该限制人民币升值幅度,发挥汇率的"名义驻锚"的作用,以此遏制通胀的进一步发展。     

Macroeconomic Policy, Exchange Rate Regimes and Economic Growth

China has been keeping high economic growth rate since it carried out managed floating exchange rate regimes in 1994, while now begins to face retrenchment pressure brought by the depression of internal and external economy. The establishment of RMB exchange rate regime should take account of the validity of macroeconomic policy, macroeconomic growth and the regional internationalization of RMB.     

Effectiveness and commitment to inflation targeting policy: Evidence from Indonesia and Thailand

The chief objective of our paper is to highlight basic features of the Information Technology (IT) policies adopted by Indonesia and Thailand, and to evaluate the commitment of the monetary authorities and the overall performances of the IT regime. The results demonstrate that the IT regime in these two economies has had some success, but not during the immediate aftermath of the Lehman Brothers’ collapse in the last quarter of 2008. Furthermore, the implementation IT policy in these economies has largely been “flexible” during the stable period, seeking the balance between narrowing the output gap, managing exchange rate volatility, and anchoring inflationary pressure. However during the turbulent period, there had been a heightened focus on anchoring inflationary expectations.     

Exchange rate regime switching in Malaysia and Singapore in response to China’s move to a basket peg: A DSGE analysis

Motivated by the observation that when China broke from its US dollar peg in 2005, Malaysia and Singapore likewise loosened their currency ties to the US dollar, this paper considers how these two countries might best respond to a hypothetical transition by China to a new basket peg regime. We specify five alternative exchange rate strategies that encompass fixed, basket, and floating regimes and gradual versus sudden transitions. To project outcomes for macroeconomic variables under these alternative regimes, we apply a dynamic stochastic general equilibrium (DSGE) model of a small open economy and incorporate exogenous shocks as actually occurred from 2005 Q1 to 2014 Q4. We then compare the strategies based on values of a cumulative loss function defined on the output gap, the inflation rate, and the real effective exchange rate. The exercise reveals that a gradual adjustment to a basket peg with long-term optimal weights is the first-best policy for both countries, where optimal weights are derived to minimize the loss function. Further, both a sudden shift to a basket peg with optimal weights and a sudden shift to a floating rate regime are superior to maintaining the dollar peg in Malaysia, but not to maintaining the existing basket peg in Singapore.     

金砖国家汇率制度演进研究——兼论危机前后金砖五国汇率表现

在发达经济体遭遇债务和高失业困扰、经济增长乏力的背景下,新兴经济体经济依然呈现快速增长、经济规模不断扩大的发展态势。以金砖五国为代表的新兴经济体在全球舞台上的地位得到提升。但是,相比第一、第二产业的强势发展,这些后起之秀在金融等软实力产业方面的表现相对较弱。随着全球化进程的推进,汇率作为一国对外交换的主要制度,成为影响国内经济稳定发展的关键问题。本文分析了金砖国家汇率制度演进的过程,总结其中的经验与教训,并对危机前后这五个国家主要汇率的变动进行了比较,以期为中国汇率制度的安排提供参考与借鉴。

Dynamic Transition of Exchange Rate Regime in China

Thepaper considers the optimal transition path for China＇s exchange rate regime. How can China successfully make the shift from the current dollar peg regime to a more desirable regime, whether a basket peg or a floating regime？ To answer this question, we develop a dynamic small open economy general equilibrium model. We construct four transition policies based on a basket peg or a floating regime and compare the welfare gains of these policies relative to maintaining the dollar peg regime. Two main results are derived from the quantitative analysis using Chinese data from 1999Q1 to 2010Q4. First, following a gradual adjustment to a basket peg regime is the most appropriate path for China to take, with minimal welfare losses associated with the shift in the exchange rate regime. Second, a sudden shift to the basket peg is the second best solution, and is superior to a sudden shift to floating because the monetary authority can efficiently determine optimal weights to attach to currencies in the basket to achieve policy goals once they adopt a basket peg regime.     

Europe’s hard fix: the Euro area

One of the most important economic policy issues is the selection of exchange rate regime. The possible choices range from the hard peg to a freely floating nominal exchange rate. Since the early 1990s a move towards the two corners of the exchange rate regime spectrum has been observed, especially in Europe with the creation of EMU. The move towards the corners is discussed from the perspective of Mundell’s “impossible trinity” which states that among the three desirable objectives (1) stabilisation of the exchange rate, (2) free international capital mobility, and (3) an effective monetary policy oriented towards domestic goals, only two can be mutually consistent. Issues related to economic integration and EMU are reviewed, focusing on the famous question: Does one size fit all? Since monetary union raises some interesting issues of political nature, not present in other exchange rate arrangements, the paper ends with a discussion about some political aspects of monetary union.     

ON THE PATH TO ECONOMIC GROWTH,DO REMITTANCES HELP? EVIDENCE FROM PANEL VARs

Despite the emergence of remittances studies, knowledge about their effect on economic development is still ambiguous. This paper investigates the impact of remittances at macroeconomic level in developing countries controlling for endogeneity problems with the use of panel vector autoregression (panel VAR). The findings suggest that remittances have a positive, albeit small, impact on economic growth even without considering the role of institutions. When institutions are included, the pattern of response remains unaltered. A distinction between low versus high remittances participation in economic activity evidences that, although the impact of remittances on growth is similar, appreciation of the exchange rate occurs in economies with high remittances participation. Finally, a distinction by geographical region reveals that Eastern European economies receive the greatest benefit from these flows, followed by the Americas and Asia; however, African economic growth does not appear to have a statistically significant impact.
