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.     

亚洲区域汇率的短期变动——对亚洲货币单位(AMU)月度指标的检验

在亚洲汇率合作进程中,区域篮子货币的设想最为引人注目。本文针对Ogawa等(2005)推出的亚洲货币单位(AMU)指数,运用月度数据对双边汇率变动进行说明,试图揭示影响区域货币对AMU汇率变动的主要经济因素和国别差异,评价AMU作为区域篮子货币的合理性。实证结果表明,区域各主要经济体与货币篮子之间的汇率变动具有某些共同特征,汇率表现的时间惯性基本一致,对美元汇率比较敏感,这意味着将上述指标纳入到区域汇率合作监控体系下具有现实合理性,但是影响变量的差异同时也意味着汇率合作上仍将面临很大的挑战。     

Food prices and long-run purchasing power parity in Africa

The purchasing power parity (PPP) theory is a cornerstone of exchange rate models in international economics. PPP is very important for two main reasons: first, it can serve as a prediction model for exchange rates, and second, it can serve as a benchmark in judging the level of exchange rate movements. This article utilised the Johansen cointegration technique in examining whether or not there is empirical support for long-run PPP in Africa. Annual data were used for exchange rates and food price indices in 25 countries covering the 1958-97 period. The empirical evidence showed strong support for long-run PPP in Africa, thereby providing wider acceptance for the applicability of PPP in exchange rate and other macroeconomic adjustment policies.     

Asia's contribution to global rebalancing

Developing Asia remains at the core of global payment imbalances. While the geographical concentration of current account imbalances is significant—with the People's Republic of China accounting for the lion's share of the region's current account surplus—how Asia contributes to global rebalancing also depends critically on the newly industrialising economies and larger Association of Southeast Asian Nations economies. Given the region's huge diversity, the necessary national macroeconomic and structural policies will vary significantly across Asia's emerging economies. Whereas near‐term rebalancing efforts will be driven primarily by macroeconomic and exchange rate policies, structural reforms are essential for boosting domestic and regional demand as sources of economic growth over medium to long‐term. We argue that regional rebalancing will depend critically on the adoption of deeper and more comprehensive structural reforms and further trade liberalisation to unlock the potential of strong domestic and regional spending—thus reducing Asia's high dependence on extra‐regional demand. Priority policies should include infrastructure spending, competition, trade, financial development, investment, immigration, and other social policies to reduce national savings.     

Business cycle synchronisation in East Asia

Against the background of the rapid inter- and intra-regional integration of East Asia, we examine the extent and nature of synchronisation of business cycles in the region. We estimate a dynamic common factor model for output growth of 10 East Asian countries. A significant common factor is shared by all Asian countries considered, except China and Japan. The degree of synchronisation has fluctuated over time, with an upward trend particularly evident for the newly industrialised economies. Synchronisation appears to mainly reflect strong export synchronisation, rather than common consumption or investment dynamics. A number of external factors, such as the oil price and the JPY–USD exchange rate, appear to play a role in synchronising activity.     

Global Financial Crises and Time‐Varying Volatility Comovement in World Equity Markets

This paper studies volatility comovement in world equity markets between 1994 and 2008. Global volatility factors are extracted from a panel of monthly volatility proxies relating to 25 developed and 20 emerging stock markets. A dynamic factor model (FM) is estimated using two‐year rolling‐window regressions. The FM's time‐varying variance shares of global factors map variations in volatility comovement over time and across countries. The results indicate that global volatility linkages are significantly stronger during financial crisis periods in Asia (1997‐1998), Brazil (1999), Russia (1998) and the United States (2000, 2007‐2008). Emerging markets are weakly synchronised with world volatility in comparison with developed markets. In particular, emerging market comovement is significantly lower than developed market comovement during the Asian and US sub‐prime crises. This suggests a degree of decoupling of emerging markets from the global drivers of volatility during these periods.     

Forecasting Performance of Exponential Smooth Transition Autoregressive Exchange Rate Models

This paper compares the forecasting performance of the Smooth Transition Autoregressive (STAR) model with the conventional linear Autoregressive (AR) and Simple Random Walk (SRW) models. The empirical analysis was conducted using quarterly data for the yen-based currencies of six major East Asian countries. We discovered strong evidence on nonlinear mean reversion in deviation from purchasing power parity (PPP). The results suggest that both the STAR and AR models outperform or at least match the performance of the SRW model. The results also show that the STAR model outperforms the AR model, its linear competitor in a 14-quarter forecast horizon. This finding is consistent with the emerging line of research that emphasizes the importance of allowing nonlinearity in the adjustment of exchange rate. JEL Classification Numbers: F31, F47     

Monetary Model of Exchange Rate for Thailand: Long-run Relationship and Monetary Restrictions

Abstract

This paper examines the long-run relationship between exchange rate and its determinants based on the flexible-price monetary model. The multivariate cointegration approach is adopted to attain our objective of this study. The empirical results provide evidence favoring the monetary approach to exchange rate for a small and open emerging economy, namely Thailand. In addition, the validity of the underlying assumptions of the monetary approach to the determination of exchange rate is established. The findings suggest that exchange rate players may effectively monitor and forecast the exchange rate movement via the money supplies, incomes, and interest rates variables of both Thailand and Japan. Besides, one has to follow the economic development of Thailand's major trading partner, Japan, to understanding the movement of exchange rate for Thailand. Moreover, our findings add new insights to accompany previous studies that documented the important influence of the US in the emerging Asian economies.     

Exchange rate expectations and foreign direct investment flows

Exchange Rate Expectations and Foreign Direct Investment Flows. — Theories about exchange rate expectations are difficult to check empirically. We study FDI data to find indirect evidence on the formation of exchange rate expectations by foreign direct investors. Using panel data techniques on exchange rate movements and FDI flows from the United States to 20 OECD countries we find that skewness of devaluations has a robust positive impact on FDI flows while average devaluation and its volatility do not. We view this evidence as consistent with the hypothesis that relatively large exchange rate movements generate mean-reverting long-run expectations. This finding is consistent with survey-based evidence on exchange rate expectations.     

Real Exchange Rates, Valuation Effects and Growth in Emerging Markets

We compare the relationship between net capital inflows, real exchange rate movements and growth for twenty emerging markets and twelve developed countries over the period 1985–2004. In developed countries low real exchange rates are associated with faster growth, but in emerging markets depreciations depress growth, even outside crisis periods, and are closely correlated with declines or reversals in net capital inflows. To investigate valuation effects of currency movements, we construct debt-weighted real exchange rate indices for emerging markets, which are more closely correlated with growth than trade-weighted indices.

文章基于协整的VAR模型从实证的角度研究了我国地区收入不平等与贸易自由化之间的长期均衡和短期动态关系。研究发现：（1）地区收入不平等、贸易自由化与经济增长之间存在长期均衡关系,贸易自由化和经济增长对于关注参数而言是弱外生变量;（2）贸易自由化在长期内减缓了我国地区收入不平等程度,但在短期内却导致了我国地区收入不平等程度的上升;（3）经济增长长期内趋于提高了我国地区收入不平等程度,但短期的影响方向不确定;（4）地区收入不平等是一个随机游走过程,不是一个含有结构突变的趋势平稳过程。     

从应对全球经济失衡视角看东亚经济金融合作

经常项目收支失衡加剧是全球经济失衡的重要体现。近年来,以美国为一极的发达国家经常项目逆差急剧膨胀;而包括中国在内的东亚国家和地区的经常项目顺差不断扩张。由于经常项目赤字滚雪球般地急剧膨胀,加上美国储蓄率过低、财政赤字高涨,导致了美国对国际资本的巨大需求。而东亚地区由于汇率体制和对美经济依存等原因,被动地持有大量美元资产并向美国提供大量资金。全球国际收支失衡不断向主要几个国家和地区集中,从中长期来看这种不均衡现象是不可持续的,东亚国家面临极大的风险。这一背景下,加强东亚区域经济金融合作是必然的选择。     

Long-Run Comovements in East Asian Stock Market Volatility

Two integrated stock markets are generally subjected to common shocks revealing that commonalities in fundamentals drive their underlying return processes. In such a case, volatility series should share a long-run component although their transitory components might temporary diverge. In this paper, we investigate stock market integration in East Asia by analyzing the co-persistent nature of their ex-post observed volatility. Using recent fractional cointegration techniques, we find that volatility of several markets converges in the long run to a common equilibrium. Our results reveal that a global integration process drives the most developed markets of the region, while no evidence of co-persistence appears for emerging markets.     

Monetary policy,exchange rate targeting and fear of floating in emerging market economies

This paper investigates whether central banks in emerging markets systematically respond to exchange rate movements. It estimates a structural general equilibrium model of a small open economy with an exchange rate-augmented Taylor-type rule for four countries. The results show that over the entire sample-period, South Africa and Mexico do not target the exchange rate, whereas Indonesia and Thailand do. In the 1980s and 1990s, all four countries targeted the exchange rate but in the aftermath of the Asian financial crisis, the Mexican peso crisis, and the end of apartheid, they all liberalized their exchange rate regimes, shifting toward inflation targeting.     

Is an Optimum Currency Area Feasible in East and South East Asia?

Abstract

In the backdrop of the recent economic crisis in the European Union, this study attempts to assess the degree of regional integration and the suitability of a monetary union in the East and South-East Asian (ESEA) region. For this purpose, we analyse the issue in a variety of ways. First, a long-run linkage of real output of the countries is tested using the cointegration analysis. Results suggest that real output of most of the countries in the region is cointegrated and move together in the long-run. To analyse the issue in detail, we focus on the impact of three different shocks, namely global, regional and country-specific, on real output of the countries. Results of impulse response and variance decomposition analysis reveal that regional shocks do not dominate in the sample countries, which is an indication of unfavourable condition to form an optimal currency area (OCA) in the region. These results are further confirmed by the outcome of computation of the modified Bayoumi and Eichengreen's Indices. Finally, we employ the concept of Generalized Purchasing Power Parity (G-PPP), which however reveals that the bilateral real exchange rate of ESEA countries move together in the long-run and share a common stochastic trend, which in turn provides some empirical support for an OCA in the region.     

An empirical analysis of China's equilibrium exchange rate: A co-integration approach

This paper estimates time specific values for China's long-run equilibrium exchange rate and develops measures of the direction and extent of misalignment based on a reduced-form real effective exchange rate (REER) model. An appropriately specified long-run equilibrium model is estimated and tested following Johansen and Juselius (1990) procedures, which is then used to construct an estimated time path for long-run equilibrium exchange rate values.Unit root tests indicated that each series can be considered as I(1) and that there was one cointegrating relationship linking the RMB series with its “fundamentals” – openness, money supply, productivity and government spending – with long-run elasticities of (0.41), (0.97), (0.51) and (0.75), respectively. The estimated error-correction model of REER determination showed that during China's latest exchange rate regime (from 2005:Q3) the RMB was undervalued by an average of 6.7 percent, which is modest compared to related studies.Estimation of the associated short-run error correction model shows that the error correction term has a statistically significant value of 0.85, implying that the actual real effective exchange rates would converge relatively quickly (just over one quarter, on average) towards their long-run equilibrium level in the absence of central bank intervention.     

Exchange Rate Volatility and Growth in Emerging Europe and East Asia

The paper investigates the impact of exchange rate volatility on growth in Emerging Europe and East Asia. Exchange rate stability has been argued to affect growth negatively as it deprives countries from the ability to react in a flexible way to asymmetric real shocks and increases the probability of speculative capital inflows and overheating. In contrast, exchange rate stability can be argued to affect growth in emerging market economies positively as transactions costs for international trade decline, uncertainty for international capital flows is less and macroeconomic stability is enhanced. Cross country panel estimations provide evidence for a negative impact of the exchange rate volatility on growth in both Emerging Europe and East Asia. Parts of this negative growth effect can be associated with exchange rate volatility caused by macroeconomic instability.     

The monetary exchange rate model in the long run: An empirical investigation

The Monetary Exchange Rate Model in the Long Run: An Empirical Investigation. — This paper uses the Johansen multivariate cointegration method to examine three variants of the monetary approach to the long-run exchange rate model: flexible price, forward-looking and sticky price monetary models. Evidence is provided for four bilateral sterling exchange rates. The sensitivity of the results to the measurement of monetary aggregates is also examined. The cointegration results provide dismal evidence for the flexible price and forward-looking models irrespective of the measurement of money. The findings are more mixed for the sticky price model, particularly when broad money is used.     

The common trend and common cycle of exports and the real exchange rate: Empirical results from Swiss data

Conclusion This paper contains an empirical analysis of the relationship of Swiss goods exports, the real exchange rate and world trade, using the common-trend-common-cycle methodology. This exercise shows that the trend and cyclical dependence of these variables are strongly different: exports and the real exchange rate exhibit a positive long-run or trend dependence of world trade whereas the short-run or cyclical relationship of exports to the real exchange rate is strongly negative with approximately a unit elasticity. These results, which differ strongly from standard dynamic regression or error correction estimates, can be interpreted as follows. In the short run we observe the strong negative cyclical relationship between exports and the real exchange rate, which we expect from short-run macroeconomic models with sticky prices. If we make the reasonable assumption that short-run real exchange rate movements are exogenous to exports and, for instance, caused by monetary policy then we come to the conclusion that cyclical real exchange rate variations lead to strong export cycles. However, in the long run, there is a completely different positive comovement of these two variables, which are both driven by the world trade trend. This common trend of exports and the real exchange rate can be understood as an equilibrium reaction of both variables, price and quantity of the exported goods, to exogenous changes in world trade given a production technology available for the country.
