Dynamics of quote and deal prices in the foreign exchange market

We empirically investigate price fluctuations of yen-dollar exchange rate using the high-frequency data recorded in the electronic broking system for seven-year period. The distribution of quote price changes has symmetric fat-tails approximated by a power law; however, that of deal price is asymmetrical. The autocorrelation function and diffusion of price changes indicate that quote price exhibits anti-correlation feature in short time scale, whereas deal price is essentially uncorrelated. The bid-ask spread shows power-law distribution and long range temporal correlations similar to that observed in absoute price changes.      

Analysis of a network structure of the foreign currency exchange market

We analyse structure of the world foreign currency exchange (FX) market viewed as a network of interacting currencies. We analyse daily time series of FX data for a set of 63 currencies, including gold, silver and platinum. We group together all the exchange rates with a common base currency and study each group separately. By applying the methods of filtered correlation matrix we identify clusters of closely related currencies. The clusters are formed typically according to the economical and geographical factors. We also study topology of weighted minimal spanning trees for different network representations (i.e., for different base currencies) and find that in a majority of representations the network has a hierarchical scale-free structure. In addition, we analyse the temporal evolution of the network and detect that its structure is not stable over time. A medium-term trend can be identified which affects the USD node by decreasing its centrality. Our analysis shows also an increasing role of euro in the world’s currency market.     

Spillovers between sovereign CDS and exchange rate markets: The role of market fear

As important variables in financial market, sovereign credit default swaps (CDS) and exchange rate have correlations and spillovers. And the volatility spillovers between the two markets become further complicated with the effect of market fear caused by extreme events such as global pandemic. This paper attempts to explore the complex interactions within the “sovereign CDS-exchange rate” system by adopting the forecast error variance decomposition method. The results show that there is a relatively close linkage between the two markets and the total spillover index of the system is dynamic. For most of the past, the exchange rate has a higher spillover effect on the sovereign CDS than vice versa. Moreover, after the market fear variables are introduced, the “sovereign CDS-exchange rate” system and market fear variables present bidirectional spillovers. The results of the study have particular significance for maintaining the financial stability and preventing risk contagion between markets.     

Monetary policy and bank performance: The role of business models

This paper examines the relationship between monetary policy and bank performance in a multiple-instrument environment, particularly highlighting the conditioning role of bank business models. Employing a unique dataset of Vietnamese commercial banks from 2007 to 2019, we display that banks react to monetary policy changes, either when the central bank increases policy rates or injects money into the economy through open market operations, by decreasing overall returns and increasing financial instability. Additionally, we document that the accumulation of foreign exchange reserves benefits bank outcomes, contrasting to open market operations, albeit the central bank uses both of these policy instruments to alter money supply in the economy. Our key analysis of interest reveals that business models considerably matter in the effects of monetary policy on bank performance. Collectively, our findings demonstrate that banks’ business models that yield more non-interest income or diversify more into different income sources may mitigate the pass-through of monetary policy to bank performance. This finding holds across all interest- and quantitative-based monetary policy indicators and across all the functions of risk-taking behavior, earning-profit capacity, and financial stability. Furthermore, while plotting the marginal effects of monetary policy, we realize that they are insignificant for banks whose business models heavily rely on non-traditional segments.     

Forecasting China's foreign exchange reserves using dynamic model averaging: The roles of macroeconomic fundamentals,financial stress and economic uncertainty

We develop models for examining possible predictors of growth of China's foreign exchange reserves that embrace Chinese and global trade, financial and risk (uncertainty) factors. Specifically, by comparing with other alternative models, we show that the dynamic model averaging (DMA) and dynamic model selection (DMS) models outperform not only linear models (such as random walk, recursive OLS-AR(1) models, recursive OLS with all predictive variables models) but also the Bayesian model averaging (BMA) model for examining possible predictors of growth of those reserves. The DMS is the best overall across all forecast horizons. While some predictors matter more than others over the forecast horizons, there are few that stand the test of time. The US–China interest rate differential has a superior predictive power among the 13 predictors considered, followed by the nominal effective exchange rate and the interest rate spread for most of the forecast horizons. The relative predictive prowess of the oil and copper prices alternates, depending on the commodity cycles. Policy implications are also provided.     

Misvaluation comovement,market efficiency and the cross-section of stock returns: Evidence from China

In this study, we examine the relation between stock misvaluation and expected returns in China's A-share market. We measure individual stocks’ misvaluation based on their pricing deviation from fundamental values, following Rhodes-Kropf et al. (2005. J. Finan. Econ. 77 (3), 561) and Chang et al. (2013. J. Bank. Finance, forthcoming), and find that the measure has strong and robust return predictive power in the Chinese market. We further form a misvaluation factor and find that misvaluation comovement and systematic misvaluation exist in the Chinese market. A comparison of our results with those of Chang et al. (2013. J. Bank. Finance, forthcoming) reveals that the misvaluation effect is much stronger in the Chinese market than in the U.S market. This evidence is consistent with the notion that the Chinese market is much less efficient than the U.S. market. Finally, we show that the return predictive power of misvaluation has weakened since China launched its split-share structure reform in 2005, which could result from the fact that the reform helps to promote market efficiency.     

汇率制度与经济绩效关系实证研究的新视角

汇率制度与经济绩效的关系是一国进行汇率制度选择的重要依据。传统的研究方法是根据各国官方所宣称的法定汇率制度来探讨两者之间的关系。由于一国所宣称的汇率制度与其实际上所采用的汇率制度之间往往存在着较大的差异 ,一些经济学家提出以实际汇率制度作为计量标准 ,来分析不同汇率制度与经济绩效的关系。这一研究方法的提出不仅开辟了实证研究汇率制度与经济绩效关系的新视角 ,而且还促使人们对汇率制度选择的依据进行重新认识与思考。     

论人民币汇率形成机制与资本账户开放

汇率形成机制与资本管理程度是开放经济最重要的两个政策安排。世界各国推进资本账户开放的动因各不相同,其中最主要的是通过资本的跨国界自由流动提高资源的配置效率。但是,近年来新兴市场国家(部分起因于资本流动过快)频繁发生的金融危机告诫我们对资本账户开放应持更谨慎的态度,而且汇率机制与资本账户管理程度必须密切配合,彼此协调,才能避免国际收支的严重失衡。文章通过阐述汇率安排与资本账户开放的关系,指出中国应循序渐进地放松资本管制和开放资本账户,逐步增大汇率制度弹性空间,最终实现资本账户开放和有管理的浮动汇率制度。     

The dynamic impact of oil price shocks on the stock market and the USD/RMB exchange rate: Evidence from implied volatility indices

Using daily data from March 16, 2011, to September 9, 2019, we explore the dynamic impact of the oil implied volatility index (OVX) changes on the Chinese stock implied volatility index (VXFXI) changes and on the USD/RMB exchange rate implied volatility index (USDCNYV1M) changes. Through a TVP-VAR model, we analyse the time-varying uncertainty transmission effects across the three markets, measured by the changes in implied volatility indices. The empirical results show that the OVX changes are the dominant factor, which has a positive impact on the USDCNYV1M changes and the VXFXI changes during periods of important political and economic events. Moreover, USDCNYV1M changes are the key factor affecting the impact of OVX changes on VXFXI changes. When the oil crisis, exchange rate reform, and stock market crash occurred during 2014–2016, the positive effects of uncertainty transmission among the oil market, the Chinese stock market, and the bilateral exchange rate are significantly strengthened. Finally, we find that the positive effects are significant in the short term but diminish over time.     

Linking organizational identification and employee performance in teams: the moderating role of team-member exchange

This study examined the influence of organizational identification on employee performance in teams. Drawing on social identity theory and self-verification theory, we predicted that organizational identification would have positive effects on employee in-role and organizational citizenship behavior (OCB) performance. Building on social exchange theory, the study further theorized that the quality of team-member exchange (TMX) would amplify the impacts of organizational identification on both types of performance. Using data from automotive dealer employees in China, we found positive relationships between organizational identification and both types of performance. In addition, TMX altered the impact of organizational identification on OCB.

The effects of exchange rate fluctuations on the stock market and the affecting mechanisms: Evidence from BRICS countries

Using data from BRICS countries, we apply the TVP-VAR model to analyze the effects of exchange rate fluctuations on their stock markets and the mechanisms leading to those effects. We find that for BRICS countries, there are similarities as well as differences in the extent, direction, and duration of the effects of exchange rate changes on the stock market. As for the affecting mechanisms, Brazil is almost entirely driven by the financial account, while the current account is dominant for Russia, whereas India, China, and South Africa depend on both mechanisms.     

Production in advance versus production to order: The role of downstream spatial clustering and product differentiation

In every production process, suppliers have to decide whether an item should be produced and stored as inventory before an explicit purchase order is received (production in advance), or whether it should be produced only after such an order is received (production to order). We study the determinants of this firm-level choice. We present a simple conceptual framework to derive predictions that we subsequently test in the empirical analysis. We argue that an increment in buyers’ spatial concentration benefits production in advance more in homogenous industries than in differentiated ones, while the benefits for production to order are larger as product differentiation increases. Consequently, the propensity to adopt one of the two production modes, following an increase in the number of local downstream buyers, changes according to the degree of product differentiation of the goods. Relying on a large data set of Italian manufacturing firms, we find empirical support to our ideas.     

Wavelet coherence analysis of returns,volatility and interdependence of the US and the EU money markets: Pre & post crisis

This research analyse the US and the EU money markets interdependence from 2004 to 2018. The study explains to what extent the volatility of the chosen money markets instruments in two regions is inter-correlated before, during and after the financial crisis of 2008. We apply the econometric analysis and estimate time-series models of class GARCH to study the historical dynamics of interbank rates and bond returns. The study demonstrates that correlation between returns of analogous money market instruments in the EU and US is not stable over time. We find that correlation rises in periods when countries are exposed to the same external shocks as global financial crisis. Wavelet coherence analysis suggests that investors do not get any advantages of portfolio diversification investing only in US treasuries with different maturities for more than 256 days and do not get any advantages at all investing only in European bonds.     

中国的贸易、境外直接投资与实际汇率的动态关系分析

本文基于向量自回归模型对中国的贸易收支、FDI与实际汇率三者之间的动态关系进行了分析，实证结果显示，三者之间长期存在互为因果的关系。长期来看FDI对贸易余额有一定的改善作用，人民币实际贬值的J曲线效应明显，贬值改善贸易余额的时滞大约为两年。出口空间的大小不是影响FDI的主要因素，实际汇率的稳定有利于吸引FDI。贸易收支的顺差和FDI的大量流入是人民币升值压力的重要来源，人民币的升值在一定时期内不会恶化我国的贸易收支，但会对FDI的流入产生一定的负面影响。     

The relationships of organizational justice,social exchange,psychological contract,and expatriate adjustment: an example of Taiwanese business expatriates

In the field of international human resource management, studies have seldom examined organizational justice, social exchange, and psychological contract together as important factors in influencing the expatriate adjustment process. The purpose of this research is to fill the research gap by examining these factors and their relationships with expatriate adjustment. The researcher conducted a survey of Taiwanese business expatriates during the first quarter of 2007, collecting 219 valid samples for analysis. A hierarchical regression model was used to test the research framework hypotheses, which showed that expatriates' perception of organizational justice has a positive influence both on their perceptions of social exchange and on their psychological contract fulfillment. Expatriates' perceived that social exchange has a positive influence on their perceptions of psychological contract fulfillment and foreign adjustment. Finally, research implications are discussed and future study suggestions are recommended.     

人民币实际有效汇率的分解和马歇尔—勒纳条件的修正

马歇尔-勒纳条件是探讨货币贬值改善贸易收支的规律,本文根据人民币实际有效汇率的特点,把它分解为美元有效汇率和人民币对美元汇率之积形式,在此基础之上,本文重新考察货币贬值改善贸易收支的条件,对传统的马歇尔-勒纳条件进行修正。从我们研究中可以看出美元实际有效汇率变化对马歇尔-勒纳条件修正的重要作用,这包括美元有效汇率对人民币汇率弹性和人民币在美元有效汇率中的权重的两种影响。另一方面,即使人民币实际有效汇率贬值存在“J”曲线效应,人民币对美元实际汇率贬值,“J”曲线是否存在还要依赖一定的条件。本文实证研究结果显示出口（或进口）与人民币对美元实际汇率、美元实际有效汇率指数和外国收入（或国内收入）之间存在着显著的协整关系,美元实际有效汇率和人民币对美元实际汇率也存在显著的协整关系。从弹性的变化来看,修正的马歇尔-勒纳条件成立,同时人民币对美元实际汇率贬值有利于改善贸易收支,美元实际有效汇率贬值会恶化中国贸易收支。而对“J”曲线效应的实证研究显示无论是人民币实际有效汇率,还是人民币对美元实际汇率贬值和美元实际有效汇率贬值,我国“J”曲线效应均不显著。     

An examination of the intraday behavior of the yen/dollar exchange rate: The relationship between trading activity and returns volatility

This paper provides additional empirical evidence of the relationship between the volatility of returns and trading activity in foreign exchange markets. Five-minute yen/dollar returns exhibit significant skewness, kurtosis, negative first-order autocorrelation and heteroskedasticity. Market activity (as measured by the intensity of quote arrivals) has a positive and statistically significant effect on conditional returns volatility. Such evidence is consistent with predictions of mixture of distrubutions models.

Environmental proactivity,competitive strategy,and market performance: The mediating role of environmental reputation

This article examines the impact of small and medium-sized enterprises' (SMEs) proactive environmental strategy on market performance through the mediating mechanism of environmental reputation. In addition, we investigate the potential moderating role of competitive strategies on the environmental reputation-market performance nexus. Data were collected from 223 SMEs. Using the hierarchical multiple regression analysis, the results show that a proactive environmental strategy positively enhances environmental reputation. Also, the influence of proactively environmental strategy on market performance is mediated by environmental reputation. In addition, our findings show the relationship between environmental reputation and market performance is greater for firms that adopt the differentiation strategy but not significant for firms adopting the low-cost and integrated strategies. Our study offers several theoretical and practical implications.
