ASIAN REAL EXCHANGE RATES AND OIL PRICES: A COINTEGRATION ANALYSIS UNDER STRUCTURAL BREAKS

We examine the long‐run relationship between Asian real exchange rates and oil prices in the presence of structural breaks. The relevance of considering breaks is demonstrated by utilizing the Johansen et al. procedure that allows for up to two predetermined breaks. Using conventional tests that do not consider breaks reveals no evidence of cointegration. However, the Johansen et al. procedure clearly demonstrates the importance of considering breaks and provides strong support for a stable long‐run relationship in all but Japan and the Philippines. Moreover, the results suggest evidence of bi‐directional causality in Malaysia and Thailand, uni‐directional causality from exchange rates to oil prices in Korea, the Philippines, and Singapore, uni‐directional causality from oil prices to the exchange rate in Indonesia, and no evidence of causality in Japan.     

金融发展与全要素生产率增长:区域差异重要吗?——来自中国省级面板数据的经验证据

基于1997-2008年中国省级面板数据以及分全国层面、沿海地区与内陆地区三个样本对金融发展与全要素生产率增长的联系及其中间渠道重新进行检验,结果发现:中国金融发展的全要素生产率增长效应与区域因素有关;中国金融发展促进全要素生产率增长的中间渠道是技术进步效应而非技术效率增长效应。这意味着,加快中国金融体系改革,从而推动金融发展对于经济增长质量的提高是非常重要的。     

Convergence in Per Capita Income Levels, Productivity Dynamics and Real Exchange Rates in the EU Acceding Countries

During a catch up process – such as the one that thecountries acceding to the EU are undergoing – there emergesa fundamental economic link between nominal and realvariables which surfaces in the dynamics of the realexchange rate (the ``Balassa–Samuelson effect'). Thisarticle analyzes some of the implications of this process forthe acceding countries addressing three main issues.First it focuses on the empirical measurement of convergencebetween acceding countries and EU-member states. Thenit analyzes the economic fundamentals of a catch up processarguing that for this process to be self-sustained, it must bebased on differential productivity growth whereby productivityin the acceding countries grows faster than that in the incumbents.Thirdly, an attempt is made to test empirically theBalassa–Samuelson effect in the EU acceding countries. Finally the article discusses some of the policy implications of thedichotomy ``real-cum-nominal convergence' on the way to EUand EMU accession.     

Do currency undervaluations affect the impact of inflation on growth?

In this paper, we investigate how the level of currency undervaluations affects the effect of inflation on growth in a sample of 62 countries over the 1980–2015 period. While previous studies find a positive effect of an undervalued currency, we show that higher currency undervaluations reinforce the contractionary effect of inflation on growth. As an undervalued currency is associated with supplementary inflation pressures arising from a cost-push inflation phenomenon and economy overheating, growth is thus penalized. This result is shown to be robust to the exclusion of currency crises episodes from our sample, and dependent of the development level of countries. Specifically, it holds in the case of emerging countries, but not for developing economies. Consequently, policies based on undervaluations should not be encouraged for emerging economies as they tend to reinforce the contractionary effect of inflation on growth.
