东亚经济冲击对称性分析与东亚货币合作

经济冲击的对称性程度,是判断一组经济体是否可以进行货币合作的一个良好指标。本文在前人研究的基础上,对经济冲击的分解变量进行了重新选择,将东亚9个经济体的经济冲击分解为供给冲击、需求冲击和货币冲击。静态与动态实证结果都显示东亚目前的冲击对称性程度还不高。未来东亚货币合作的方向,除了在整体上继续推动东亚各经济体在各领域的合作外,重点是要推进大国之间的经济合作与协调。     

Emerging Asia: Decoupling or Recoupling

In this paper, we investigate the degree of real economic interdependence between emerging East Asian and major industrial countries to shed light on the heated debate over the ‘decoupling’ of emerging East Asia. We first document the evolution of macroeconomic interdependence for emerging East Asian economies through changing trade and financial linkages at both the regional and global levels. Then, by employing a panel vector autoregression (VAR) model, we estimate the degree of real economic interdependence before and after the 1997/98 Asian financial crisis. Empirical findings show that real economic interdependence increased significantly in the post‐crisis period, suggesting ‘recoupling’, rather than decoupling, in recent years. Output shocks from major industrial countries have a significant positive effect on emerging East Asian economies. More interestingly, the reverse is also true. Output shocks from emerging East Asia (and China) have a significant positive effect on output in major industrial countries. The result suggests that macroeconomic interdependence between emerging East Asia and industrial countries have become ‘bi‐directional’, defying the traditional notion of the ‘North–South relationship’ as one of ‘uni‐directional’ dependence.

FDI,Growth and the Asian Financial Crisis: The Experience of Selected Asian Countries

This paper studies the trends in foreign direct investment (FDI) flows into selected South‐East Asian and East Asian economies after the Asian crisis. Empirical evidence indicates that South‐East and East Asian economies are recovering from the Asian crisis with strong output growth driven largely by export growth. However, output growth in the post‐crisis period is also accompanied by rising unemployment rates, growing government deficits, and declining FDI inflows into the South‐East Asian region. The declining FDI inflows into South‐East Asia after the crisis is of concern, as our empirical results show that FDI is important for output growth in the region. Our results also suggest that there might have been structural changes in the regional economies that could have led to a downward shift in the output growth of Asian economies in the post‐crisis period. This raises the issue of the sustainability of their output growth in the post‐crisis period.     

金融危机与区域经济发展模式的转变——以沿海四大区域经济模式为例

全球性的金融危机已经开始对我国实体经济产生较明显的影响,代表我国四大区域经济发展模式的苏州地区、温州地区、泉州地区及东莞地区经济也在此次危机中遭受了不同程度的冲击。本文依据此次金融危机前的数据,从人均经济指标、经济活动主体特征、贸易方式、经济开放度等方面综合比较了四种模式的异同,并利用2008年的数据,通过比较外贸出口额、失业率等八个经济指标的变化,分析了各地区在金融危机下的经济稳定性和抗风险能力,进而对我国区域经济发展模式的转型和调整提出建议。     

全球经济危机对我国出口贸易的影响

首先定性地分析了发达国家的经济发展和我国出口贸易十多年的走势,探究不同时期两者之间的变化是否趋同;然后选取美国、欧元区的国内GDP和商品相对价格指标,建立这两个因素对我国的出口贸易的影响程度的计量方程;随后,建立两个不同的VAR模型,第一个模型考察我国出口贸易和美、欧实体经济间的长期协整关系,运用脉冲响应函数分析外部冲击的滞后效应;针对当前金融危机造成货币紧缩,各国均采取一系列的刺激经济恢复的手段,在第二个VAR模型中,选取了较为代表性的外部因素——欧美的信贷政策和居民消费,以及作为国际资本流动因素的我国FDI,并运用脉冲响应函数考察这些政策因素对我国出口贸易产生的长期影响。最后根据实证结论提出政策建议。     

Human development effects of large changes in food prices: Does openness policy matter?

This paper analyses the effects of food price shocks on selected disaggregated human development indicators and investigates the role of openness policy in mitigating the adverse effects of large changes in food prices. Using a panel of 74 developing countries from 1980 to 2012, I find that positive food price shocks reduce life expectancy at birth both in the fixed-effect model and in the dynamic panel model while negative food price shocks do not seem to matter for this human development indicator in the static model but adversely affect it in the dynamic model. I also find that both positive and negative shocks have no effect on youth literacy rate; this probably means that households do not react to food price shocks by taking children out of school. Analysing the role of commercial openness, I find that openness policy enhances countries’ capacity to manage the adverse effects of food price shocks on life expectancy at birth. This suggests that the tempting policy option of reducing openness to trade during food price shocks is not an efficient choice as regards the human development. Countries must therefore set institutional arrangements that could prevent policy-makers from taking this inefficient policy option.     

Explaining business cycles in small open economies: ‘How much do world prices matter?’

This paper analyzes the role of world price shocks - fluctuations in the prices of capital, intermediate, and primary goods, and in the world real interest rate - in the generation and propagation of business cycles in small open developing countries. I construct a stochastic dynamic multi-sector small open economy model. The model is a variant of the specific-factors model and reflects the major structural characteristics of developing economies. I utilize variance decomposition methods to quantitatively evaluate the impact of world price shocks. The results indicate that world price shocks account for a significant fraction of business cycle variability in developing countries.     

On the Causes and Effects of Exchange Rate Volatility on Economic Growth: Evidence from Ghana

What drives exchange rate volatility, and what are the effects of fluctuations in the exchange rate on economic growth in Ghana? These questions are the subject matter of this study. The results showed that while shocks to the exchange rate are mean reverting, misalignments tend to correct very sluggishly, with painful consequences in the short run as economic agents recalibrate their consumption and investment choices. About three quarters of shocks to the real exchange rate are self-driven, and the remaining one quarter or so is attributed to factors such as government expenditure and money supply growth, terms of trade and output shocks. Excessive volatility is found to be detrimental to economic growth; however, this is only up to a point as growth-enhancing effect can also emanate from innovation, and more efficient resource allocation.     

Possible External Shocks to Asia in 2001: How Vulnerable Are the Regional Economies?

In 2001, threats of a U.S. economic slowdown, a moderation of economic growth in the EU, sharp deceleration of the global electronics cycle, and high oil prices could be some of the potential external shocks clouding Asia's economic outlook. This article analyzes these external shocks and assesses which Asian economies are most (or least) vulnerable to these exogenous shocks. © 2001 John Wiley & Sons, Inc.     

On the Relationship Between Openness and Growth in China: Evidence from Provincial Time Series Data

The effect of increasing openness on real output growth in China is examined. The framework of analysis is a regression model that uses time‐series data for each province. For east coastal provinces, increasing openness is found to have positive effects on real output growth, and some of the effects are statistically significant. The results appear to be broadly consistent with the new growth theories that openness enhances long‐run growth through its impact on technological improvement. However, inland provinces in China have been isolated from world trade for several decades and their economies devastated. An increased openness in these provinces is found to have, in most cases, negative effects on real output growth.     

Commodity currencies

This paper looks at real exchange rate behavior by focusing on three OECD economies (Australia, Canada, and New Zealand) where primary commodities constitute a significant share of their exports. For Australia and New Zealand especially, we find that the US dollar price of their commodity exports (generally exogenous to these small economies) has a strong and stable influence on their floating real rates, with the magnitude of the effects consistent with predictions of standard theoretical models. However, after controlling for commodity price shocks, there is still a purchasing power parity puzzle in the residual. The results here are relevant to developing commodity-exporting countries as they liberalize their capital markets and move towards floating exchange rates.     

系统性金融风险的度量及其时变经济效应研究

基于TVP-SV-SVAR模型，分析六个不同金融子市场风险对实体经济的实时冲击效应，结合时变脉冲响应方法构建了动态权重系统性金融风险综合指数，并区分高低风险状态探讨其对实体经济的影响。结果表明，银行部门、股票市场和外部金融市场对系统性金融风险的贡献较大；基于对实体经济冲击视角的动态权重系统性金融风险综合指数与样本期内实际金融经济事件的发展趋势一致；不同状态下系统性金融风险对经济增长的冲击效应不同：短期来看，高风险点系统性金融风险抑制经济增长，低风险点系统性金融风险促进经济增长；长期来看，系统性金融风险在高低状态下对经济增长均有负向冲击效应。研究结论对于防范和化解系统性金融风险的宏观审慎政策制定具有重要的参考意义。     

中国在东亚生产网络中的分工地位检验——基于贸易增长途径的视角

运用贸易增长分解方法,将东亚各国对中国的出口增长分解为广度增长、数量增长与价格增长,从贸易增长途径这一新视角探讨了中国与东亚各国的相对分工地位。研究结果显示,日本、韩国、新加坡和马来西亚四国对中国的出口以价格增长为主,而菲律宾、泰国和印度尼西亚三国主要以数量增长带动对中国的出口贸易。这说明中国并非位于分工体系的底端,而且其分工地位将逐步提高,因为在东亚七国对中国的出口贸易中,数量增长表现出了趋于主导的态势。由此看来,中国在东亚生产网络中的分工地位处在上升阶段,并逐步向分工体系的高端收敛。     

Determinants of FDI inflows to Arab economies

The paper studies location determinants of foreign direct investment (FDI) to 16 Arab economies over the period from 1984 to 2012, by employing Arellano–Bover/Blundell–Bond linear dynamic panel data estimation. We find that market size, trade openness, preferential trade agreements and financial development have significant positive impact on FDI inflows to Arab economies. FDI in Arab economies appears to be resource seeking since the total oil supply variable is positive and significant. The paper finds that better institutions and educated labour force may play a key role in attracting FDI inflows. We suggest that Arab economies should sequence their economic policy measures with the institutional ones, beginning with a focus on privatization and trade liberalization, and subsequently shift to improvement in economic growth.     

The impact of foreign interest rates on the economy: The role of the exchange rate regime

It is often argued that many economies are affected by conditions in foreign countries. This paper explores the connection between interest rates in major industrial countries and annual real output growth in other countries. The results show that high foreign interest rates have a contractionary effect on annual real GDP growth in the domestic economy, but that this effect is centered on countries with fixed exchange rates. The paper then examines the potential channels through which major-country interest rates affect other economies. The effect of foreign interest rates on domestic interest rates is the most likely channel when compared with other possibilities, such as a trade effect.     

Monetary policy in developing countries: lessons from Kenya

We estimate and then simulate a model of Kenyan economic development from 1965 to 1997 with two objectives in mind. The first is to demonstrate the degree of volatility of cyclical shocks that developing countries experience and to calculate the domestic nominal adjustments required by these shocks under both irrevocably fixed and free exchange rates.A comparison of these counterfactual nominal adjustments identifies the short-run implications for an economy of the choice of exchange rate regime. The second objective is to provide an estimate of the consequences for the economic development of Kenya of the lack of a coherent monetary order (excessive domestic credit expansion and overvalued exchange rate) throughout most of the period since 1965.A neoclassical convergence growth model based on Barro and Sala-i-Martin (1992) is employed and calibrated to represent the long-run growth path of real GDP in Kenya. A short-run four-sector CGE model is constructed that allows for cyclical movements of real GDP about the convergence growth path. The cyclical model focuses on the adjustment of the relative price of non-traded goods that is required to ensure short-run equilibrium in the non-traded goods sector. Given that terms of trade shocks dominated the macro environment of Kenya over the sample period, we find that a free exchange rate regime would have insulated the economy to a greater degree than an irrevocably fixed regime. In the growth decomposition exercise, we estimate that the two largest (and negative) influences on Kenyan economic growth were the decline in the external terms of trade from 100 in 1965 to an average of 79.5 over the 32-year time period, and the overvalued Kenyan shilling represented by a premium on the parallel market for foreign exchange. Overall, we estimate that the overvalued exchange rate reduced economic growth by an average of 0.47 per cent per annum over the 32 years.     

AFTA,Income Growth,and Income Convergence in ASEAN

The rapid economic growth experienced by the core ASEAN members (comprised of Singapore, Malaysia, Thailand, the Philippines, and Indonesia) since the 70s was generally attributed to openness policies adopted by the respective governments. Despite this contention, however, there is little evidence to suggest that greater openness will eventually lead to a convergence of the member countries, particularly with the present of external shocks. The introduction of ASEAN Free Trade Area (AFTA) in 1992 was also partly an attempt to hedge the region from external shock, while possibly further promoting economic development in the region. This study, therefore, is an attempt at examining in greater detail the impact of AFTA and openness on ASEAN economic growth, in the present of external shock. The results indicate that convergence in ASEAN is conditional upon several control variables taking place, in addition to openness. Additionally, while AFTA has a positive effect on economic growth, its impact on convergence is somewhat ambiguous in the presence of external shocks.     

Demand shifts and willingness to pay in applied trade models

Emerging issues facing open economies, including global value chains and non-tariff measures, have important implications for demand that are often not well suited for analysis with the supply-side mechanisms commonly found in economic models – namely taxes and productivity. The aim of this paper is to provide a methodological approach for implementing demand-side changes. Specifically, the approach adapts the Armington equation to model a change in consumers' willingness to pay for imports. To illustrate, we estimate the impacts of the World Trade Organization's Trade Facilitation Agreement (TFA). Estimated ad valorem equivalents of the TFA are applied as demand-side shocks to consumers' willingness to pay in a global applied general equilibrium model and the results compared to those obtained using Samuelson's iceberg approach. We find that the iceberg approach results in a technical change which increases the productivity of imports, raising real GDP, while the willingness-to-pay approach causes a smaller rise in real GDP, although trade increases further. The impact on the terms of trade differs significantly between the two mechanisms, with prices falling as costs fall, under the iceberg method, and rising with increased willingness to pay. Our results clearly show that the choice of mechanism matters.     

汇率、贸易开放度与经济增长:短期波动与长期均衡——基于自回归分布滞后模型的经验研究

文章通过构建自回归分布滞后模型研究了汇率波动情况下贸易开放度与经济增长的长期关系,然后建立误差修正模型对两者之间的短期关系进行了刻画,重点考察了1978-2008年我国贸易开放度与经济增长在不同阶段的影响机制。经验分析结果表明,外商直接投资和贸易开放度对经济增长的短期效应大于长期效应;而人民币实际汇率对于经济增长的效应,则是长期效应大于短期效应。当外商直接投资、贸易开放度和人民币实际汇率造成的短期波动偏离长期的均衡时,经济增长能够通过自动调整趋于稳定。
