Quantitative Comparisons on the Intrinsic Features of Foreign Exchange Rates between the 1920s and the 2010s: Case of the USD-GBP Exchange Rate * 20世纪20年代至2010年代汇率内在特征的定量比较——以美元兑英镑汇率为例*

This paper quantitatively compares the intrinsic features of the daily USD-GBP exchange rates in two different periods, the 1920s and the 2010s, under the same freely floating exchange rate system. Even though the foreign exchange markets in the 1920s seem to be much less organized and developed than in the 2010s, this paper finds that both the long memory volatility property and the structural break appear to be the common intrigue features of the exchange rates in the two periods by using the FIGARCH model. In particular, the long memory volatility properties in the two periods are found to be upward biased and overstated because of the structural breaks in the exchange markets. Thus this paper applies the Adaptive-FIGARCH model to consider the long memory volatility property and the structural breaks jointly. The main finding is that the structural breaks in the exchange markets affect the long memory volatility property significantly in the two periods but the degree of the long memory volatility property in the 1920s is reduced more remarkably than in the 2010s after the structural breaks are accounted for; thus implying that the structural breaks in the foreign exchange markets in the 1920s seem to be more significant.
本文定量比较了在同一自由浮动汇率制下,20世纪20年代和2010年代两个不同时期美元兑英镑每日汇率的内在特征。尽管20世纪20年代的外汇市场似乎远不如2010年代有组织和发达,但本文通过使用FIGARCH模型发现,长记忆波动性和结构性断裂似乎是这两个时期汇率的共同特征。特别是,由于外汇市场的结构性断裂,这两个时期的长记忆波动特性被发现是向上偏倚和夸大的。因此,本文采用自适应figarch模型综合考虑了长记忆波动特性和结构断裂。研究发现,外汇市场的结构性断裂显著影响了两个时期的长期记忆波动特性,但在考虑结构性断裂后,20世纪20年代的长期记忆波动特性的程度比2010年代显著降低;因此,这意味着20世纪20年代外汇市场的结构性断裂似乎更为显著。

This research intends to investigate the progress made in East Asian bond market integration thus far. Price-based measures (AAD indicator and beta-convergence measure), quantity-based measures and econometric techniques (co-integration test, error correction model based Granger causality test) are employed in the analysis. Even though East Asian government bond markets have become more integrated since 2001, the differentials among the markets still remain significantly high. The bond market integration process seems slow. The convergence of bond markets sped up in 2003 and after the 2008 world financial crisis, implying the important role of government policies in integrating the regional bond markets. East Asian bond market integration may need more government-directed measures.
本研究旨在探讨东亚债券市场整合至今所取得的进展。在分析中采用了基于价格的测度(AAD指标和贝塔收敛测度)、基于数量的测度和计量经济学技术(协整检验、基于误差修正模型的格兰杰因果检验)。尽管东亚政府债券市场自2001年以来一体化程度有所提高,但市场之间的差异仍然很大。债券市场一体化进程似乎缓慢。在2003年和2008年世界金融危机之后,债券市场的趋同速度加快,这意味着政府政策在整合区域债券市场方面发挥了重要作用。东亚债券市场一体化可能需要更多政府主导的措施。

In this study, we examined the fractal structure of the Nikkei225, HangSeng, Shanghai Stock Exchange and Straits Times Index of Singapore. Empirical analysis was performed via non-parametric, semi-parametric long memory tests and also fractal dimension calculations. In order to avoid spurious long memory features, besides the Detrended Fluctuations Analysis (DFA), we also used Smith's (2005) modified GPH method. As for fractal dimension calculations, they were conducted via Box-Counting and Variation tests. According to the results, while there is no long memory property in log returns of any index, we found evidence for long memory properties in the volatility of the HangSeng, the Shanghai Stock Exchange and the Straits Times Index. However, we could not find any sign of long memory in the volatility of Nikkei225 index using either the DFA or modified GPH test. Fractal dimension analysis also demonstrated that all raw index prices have fractal structure properties except for the Nikkei225 index. These findings showed that the Nikkei225 index has the most efficient market properties among these markets.
在本研究中,我们检验了日经225指数、恒生指数、上海证券交易所指数和新加坡海峡时报指数的分形结构。通过非参数、半参数长记忆测试和分形维数计算进行实证分析。为了避免虚假的长记忆特征,除了使用去趋势波动分析(DFA)外,我们还使用了Smith(2005)改进的GPH方法。分形维数的计算采用Box-Counting和Variation试验。结果显示,虽然任何指数的对数回报都不存在长记忆性,但我们在恒生指数、上证指数和海峡时报指数的波动率中发现了长记忆性的证据。然而,无论是DFA还是修正GPH检验,我们都没有发现日经225指数波动率存在长记忆的迹象。分形维数分析也表明,除日经225指数外,所有原始指数价格均具有分形结构特征。这些发现表明,日经225指数在这些市场中具有最有效的市场属性。

This paper provides a theoretical setup for an analysis of strategic relationships inherent to activities of an innovative multinational enterprise (MNE) and a local company in a host country. Additionally, we explore the incentives of the host country's government to provide subsidies to attract foreign direct investment (FDI) and to protect outcomes of R&D activities conducted by the MNE. We show that the MNE's commercial interests may collide with local companies’ over protection of IPRs. Therefore, the extent of knowledge spillovers from the MNE to the local company and the magnitude of incentives to the MNE perform a crucial function in determining the optimal policy mix of IPR protection and FDI subsidies of the host country's government.
本文为分析创新型跨国企业(MNE)与东道国当地公司活动中固有的战略关系提供了理论框架。此外,我们还探讨了东道国政府提供补贴以吸引外国直接投资(FDI)和保护跨国公司开展的研发活动成果的激励机制。研究表明,跨国公司的商业利益可能与当地公司对知识产权的过度保护发生冲突。因此,跨国公司对当地公司的知识溢出程度和对跨国公司的激励程度在决定东道国政府知识产权保护和外国直接投资补贴的最优政策组合方面发挥着至关重要的作用。

Alternative Monetary Policy Rules in a Small Open Economy with Financial Frictions: The Case of Korea 具有金融摩擦的小型开放经济中的货币政策规则选择——以韩国为例

This paper first shows an empirical result of VAR that Korean economy has experienced a severe economic contraction to an exogenous country spread shock. To analyze the effect of alternative monetary policy on the economy, the paper sets up a multi-sector small open economy new Keynesian (NK hereafter) model with financial frictions due to asymmetric information between firms and financial intermediaries along the line of Bernanke et al. (1999). It shows that the small economy with financial frictions is more vulnerable to the exogenous shocks such as the foreign exchange rate shock under the fixed exchange rate regime than under the flexible exchange regime. It also shows that the interest rate rule that responds to financial market conditions is better than any other interest rate rules only if it does not react to the exchange rate fluctuations. Moreover, an interest rate rule that responds to the exchange rate fluctuations, i.e. the monetary policy under the managed floating exchange rate regime is inferior to the monetary policy rules that do not respond to the exchange rate fluctuations. Finally, it shows that the monetary authority needs to stabilize a narrow price index such as domestic price index rather than a general price index such as consumer price index under the financial friction circumstances.
本文首先展示了VAR的实证结果,即韩国经济经历了严重的外生国家蔓延冲击的经济收缩。为了分析替代货币政策对经济的影响,本文按照Bernanke et al.(1999)的思路,建立了一个考虑企业和金融中介机构之间信息不对称导致的金融摩擦的多部门小型开放经济新凯恩斯模型(以下简称NK)。结果表明,存在金融摩擦的小型经济体在固定汇率制度下比在浮动汇率制度下更容易受到汇率冲击等外生冲击的影响。它还表明,只有在对汇率波动不作出反应的情况下,对金融市场情况作出反应的利率规则才比任何其他利率规则更好。此外,对汇率波动作出反应的利率规则,即有管理的浮动汇率制度下的货币政策,不如不对汇率波动作出反应的货币政策规则。最后表明,在金融摩擦环境下,货币当局需要稳定的是国内物价指数等狭义物价指数,而不是消费者物价指数等广义物价指数。

Decomposition into Tradables and Nontradables and the Purchasing Power Parity (PPP) Hypothesis of the Real Won-dollar Exchange Rate 可贸易品和不可贸易品的分解和韩元兑美元实际汇率的购买力平价(PPP)假设

The purpose of this paper is to test the purchasing power parity (PPP) hypothesis using the won-dollar real exchange rate and analyze the effect of the decomposition into tradables and non-tradables on the change of the won-dollar real exchange rate. This paper decomposes the CPI-based real exchange rate into two parts according to Engel (1999); one is the relative price of traded goods between the countries, the other is a component that is a weighted difference of the relative price of nontraded-to traded-goods prices in each country. We construct this by comparing the component subsection weights in CPI. The empirical analysis of this paper consists of two parts as follows. First, we conducted a traditional time series analyses of the real exchange rate, tradable and non-tradable parts respectively, thereby testing the PPP hypothesis and other important hypotheses. Secondly, this paper conducted a Mean Squared Error (MSE) analysis to evaluate the relative contribution of tradable and non-tradable parts to the change of real exchange rate. From the time series analysis, it is not guaranteed that the PPP hyThe purpose of this paper is to test the purchasing power parity (PPP) hypothesis using the won-dollar real exchange rate and analyze the effect of the decomposition into tradables and non-tradables on the change of the won-dollar real exchange rate.

Secondly, this paper conducted a Mean Squared Error (MSE) analysis to evaluate the relative contribution of tradable and non-tradable parts to the change of real exchange rate. From the time series analysis, it is not guaranteed that the PPP hypothesis hold in the long run. The Balassa-Samuelson hypothesis is not either, since the sample size is too small to avoid the 'power problem.' In addition, the result of the Mean Squared Error analyses show that tradable goods are more important in explaining the won-dollar real exchange rate dynamics than that of the non-tradable goods. All in all, the results of this empirical analysis are in contrast with the explanation that if the long-run PPP hypothesis does not hold, it is mainly caused by the transaction cost and the non-tradable goods.
本文的目的是利用韩元-美元实际汇率检验购买力平价(PPP)假设,并分析可贸易和不可贸易的分解对韩元-美元实际汇率变化的影响。根据Engel(1999)的理论,本文将基于cpi的实际汇率分为两部分;一个是国家间贸易商品的相对价格,另一个是每个国家非贸易商品相对价格与贸易商品价格的加权差异。我们通过比较CPI中的组件子权重来构建此模型。本文的实证分析分为以下两部分。首先,我们分别对实际汇率、可贸易部分和不可贸易部分进行了传统的时间序列分析,从而检验了PPP假设和其他重要假设。其次,采用均方误差(Mean Squared Error, MSE)分析,评价可交易部分和不可交易部分对实际汇率变动的相对贡献。从时间序列分析来看,并不能保证购买力平价的变化。本文的目的是利用韩元-美元实际汇率来检验购买力平价(PPP)假设,并分析分解为可贸易和不可贸易对韩元-美元实际汇率变化的影响。根据Engel(1999)的理论,本文将基于cpi的实际汇率分为两部分;一个是国家间贸易商品的相对价格,另一个是每个国家非贸易商品相对价格与贸易商品价格的加权差异。我们通过比较CPI中的组件子权重来构建此模型。本文的实证分析分为以下两部分。首先,我们分别对实际汇率、可贸易部分和不可贸易部分进行了传统的时间序列分析,从而检验了PPP假设和其他重要假设。其次,采用均方误差(Mean Squared Error, MSE)分析,评价可交易部分和不可交易部分对实际汇率变动的相对贡献。从时间序列分析来看,不能保证PPP假设在长期内成立。巴拉萨-萨缪尔森假设也不是,因为样本量太小,无法避免“功率问题”。此外,均方误差(Mean Squared Error)分析结果显示,在解释韩元兑美元实际汇率变动时,可贸易商品比不可贸易商品更重要。总而言之,这一实证分析的结果与长期PPP假设不成立的解释形成了对比,这主要是由交易成本和非贸易品造成的。

From the time series analysis, it is not guaranteed that the PPP hypothesis hold in the long run. The Balassa-Samuelson hypothesis is not either, since the sample size is too small to avoid the 'power problem.' In addition, the result of the Mean Squared Error analyses show that tradable goods are more important in explaining the won-dollar real exchange rate dynamics than that of the non-tradable goods. All in all, the results of this empirical analysis are in contrast with the explanation that if the long-run PPP hypothesis does not hold, it is mainly caused by the transaction cost and the non-tradable goods.","PeriodicalId":41122,"journal":{"name":"East Asian Economic Review","volume":"15 1","pages":"129-161"},"PeriodicalIF":0.8,"publicationDate":"2011-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64812497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using the US Treasury International Capital (TIC) data, this paper attempts to analyze the size and trend of foreign investment in the U.S. in the form of equities, bonds and bank lending during the period of 2001-2007. In addition, this paper assesses the determinants of foreign investment in the U.S., using the financial gravity model which includes an East Asian dummy as an explanatory variable. The results show that most East Asian countries have invested more in the U.S. than the optimal level suggested by the gravity model. Such an over-investment is more evident in long-term bond investment than in equity investment or bank lending. Thus, the results confirm that global imbalance does exist between East Asian countries and the U.S.
本文利用美国财政部国际资本(TIC)数据,试图分析2001-2007年期间以股票、债券和银行贷款形式在美国的外国投资的规模和趋势。此外,本文利用金融引力模型评估了外国投资在美国的决定因素,该模型包括一个东亚虚拟人作为解释变量。结果表明,大多数东亚国家在美国的投资超过了引力模型所建议的最优水平。这种过度投资在长期债券投资中比在股票投资或银行贷款中更为明显。因此,研究结果证实东亚国家与美国之间确实存在全球失衡
