An empirical study of portfolio-balance and information effects of order flow on exchange rates

We propose a simple structural model of exchange rate determination which is inspired by the analytical framework recently forward by Bacchetta and van Wincoop (2006) and allows us to disentangle the portfolio-balance and information effects of order flow on exchange rates. We estimate this model employing an innovative transaction data-set that covers all indirect foreign exchange transactions completed in the USD/EUR market via EBS and Reuters between August 2000 and January 2001. Our results indicate that the strong contemporaneous correlation between order flow and exchange rates is largely due to portfolio-balance effects. This result also appears to carry through the four FX intervention events that appear in our sample.     

Time to equilibrium in exchange rates: G-10 and Eastern European economies

This paper reports different times-to-equilibrium for G-10 developed economies and the Eastern European emerging economies. By applying a novel method of value-weighted index to highly-trade-linked economies, we test the purchasing power parity to the full length of time-to-equilibrium. The times-to-equilibrium obtained are: 6 years for developed and 2 years for emerging economies. These results are consistent with the sticky price hypothesis: economies trading in highly aggregated capital goods take longer time to reach price equilibrium in the face of overshooting exchange rates: the opposite is true for primary exporters. This finding is new for these two groups, and could be compared usefully with the earlier reports of long half-life for developed countries. Also, our method of measurement establishes the actual time of the theory prediction on price-to-currency relationship. It is possible to apply this methodology to study more groups of countries.     

Dynamic news effects in high frequency Euro exchange rates

This paper investigates the dynamic, short-run response of Euro exchange rate returns to the information surprise of global macroeconomic announcements. In addition, it advocates a new approach to modelling intraday exchange rate volatility to allow accurate characterisation of reactions. US macroeconomic news generates far more dramatic responses in EUR–USD returns and returns volatility than news on the macroeconomic performance of other countries. However, some Eurozone and German indicators are also important and UK announcements are important for the EUR–GBP rate. The reaction of exchange rate returns to news is very quick and occurs within the first 5 min of the release with very little reaction in the 15 min before and after. These findings show that exchange rates are strongly linked to fundamentals in the 5-min intervals immediately following the data release. Reactions to news are found to vary in magnitude over the sample, with the largest responses to news occurring in response to turning points in the cumulative flow of news.     

Frequency of observation and the estimation of integrated volatility in deep and liquid financial markets

Using two newly available ultrahigh-frequency datasets, we investigate empirically how frequently one can sample certain foreign exchange and U.S. Treasury security returns without contaminating estimates of their integrated volatility with market microstructure noise. Using the standard realized volatility estimator, we find that one can sample dollar/euro returns as frequently as once every 15 to 20 s without contaminating estimates of integrated volatility; 10-year Treasury note returns may be sampled as frequently as once every 2 to 3 min on days without U.S. macroeconomic announcements, and as frequently as once every 40 s on announcement days. Using a simple realized kernel estimator, this sampling frequency can be increased to once every 2 to 5 s for dollar/euro returns and to about once every 30 to 40 s for T-note returns. These sampling frequencies, especially in the case of dollar/euro returns, are much higher than those that are generally recommended in the empirical literature on realized volatility in equity markets. The higher sampling frequencies for dollar/euro and T-note returns likely reflect the superior depth and liquidity of these markets.     

Macroeconomic news and exchange rates

This paper examines the relationship between macroeconomic news and the dollar–Mark and dollar–Yen exchange rates. We employ high-frequency observations for a 10-year period. We investigate whether exchange rate observations need to be sampled at a high frequency in order to detect significant effects from news announcements on mean returns and volatility. We examine the linearity and symmetry of the responses to news and also allow the effects of the news announcements to vary across states of the economy. We find that news indicating a stronger U.S. economy causes an appreciation of the U.S. dollar, that the responses are essentially complete within 5 min, and that measuring the responses over 6-h intervals eliminates the statistical significance of the news. The effects of news appear linear and symmetric but there is some evidence that the effects depend on the state of the economy.     

Can dual-currency sovereign CDS predict exchange rate returns?

This paper examines both the time-series and cross-sectional variation in the difference between US dollar and Euro denominated sovereign CDS spreads for a group of Eurozone countries. We find that the spread difference between dual-currency sovereign CDS significantly affects the bilateral exchange rate returns. In addition, the difference could predict the cumulative exchange rate returns up to 10 days. The results strongly suggest that the difference contains important information for the exchange rate dynamics at various phases of the crisis.     

Interest parity,cointegration, and the term structure: Testing in an integrated framework

In this paper, we develop a methodology for testing jointly the validity of the expectations hypothesis of the term structure (EHTS) and the uncovered interest rate parity (UIRP) within the framework provided by cointegration theory. For this purpose, we use data on interest rates from the U.S. dollar-Libor, GBP-Libor, and Euro-Libor markets with maturities ranging from 7 days to 12 months. The main findings of our analysis are as follows: (i) we fail to find the correct rank of the cointegration space suggested by our methodology; (ii) with the application of tests for parameter stability in cointegrated models, we show that our cointegration results are sample independent and that the estimated coefficients do not suffer from instabilities in recursive estimations; (iii) from the moving average representation of the model, we estimate the common stochastic trends whose components establish, in the USD/Euro case, the interdependence of interest rates in the formation of the driving forces of the system; (iv) we manage to identify with the two theories a sub-space of the estimated cointegration space.     

The nexus between financial integration and real economy: Solow-growth model concept

This paper aims to investigate the nexus between financial integration and the real economy in ASEAN + 3 economies based on the concept of Solow-Growth Model. The equity indices as a proxy for financial markets are collected from each ASEAN + 3 members and are segmented between two periods; before and after the financial cooperation agreement period. The finding presents several outcomes; 1) no cointegration nexus is found in the system during the pre-agreement periods; 2) the markets are found cointegrated during the post-agreement period, 3) financial integration is found to influence the real sectors of ASEAN + 3 economies. Finally, this study offers policy implications to improve financial integration for stabilizing the real economy.     

Design and evaluation of an advanced continuous data level auditing system: A three-layer structure

Audit efficiency and effectiveness can be significantly affected by data aggregation during audit procedures. Previous studies highlight that an appropriate level of data aggregation is needed because a continuous auditing (CA) system often generates numerous alarms. To respond to this issue, this study proposes a CA system with a three-layer structure. In the first layer of the proposed system, all journal entry level transactions are classified and aggregated using defined rules; any transactions that deviate from these rules are identified as unusual transactions. The second layer detects the observations that violate controls. Analytical monitoring models are developed in the final layer to identify observations that statistically deviate from an organization’s typical business behaviors. To examine whether the proposed three-layer CA system enhances the effectiveness of a CA system in identifying financial irregularities, this study empirically tests the proposed models using real-world journal entry data from a construction company. The results indicate that the proposed framework enhances audit effectiveness and efficiency.     

The importance of size in private equity: Evidence from a survey of limited partners

Using a comprehensive survey, we show that investors with a larger capital allocation to private equity are more specialized − measured by the degree to which the investor focuses on private equity rather than other classes of investments − and have a wider scope of due diligence and investment activities. Other investor characteristics (experience, type, location, compensation structure, number of funds under management) play no role. In particular, endowments are not special according to the survey measures. These results are consistent with the changing LP–GP relationship in private equity as capital is increasingly concentrated in the hands of large investors.     

Uncovered interest parity: The long and the short of it

Uncovered interest rate parity (UIP) is a theoretical relation linking changes in exchange rates and corresponding interest rate differentials. Despite its considerable intellectual appeal, uncovered interest rate parity has very often been found wanting empirically. I reinvestigate this relation using a 17-country panel of historical time series data at its longest—for the US–UK country pair—spanning 217 years. I find results that are largely consistent with theory: over the long term, in most countries, bond yields expressed in common currency bear a positive relationship to one another as UIP predicts. This is in contrast to the very nearly opposite findings reported in much of the literature and now taken as a stylized fact.     

Gaining a competitive edge through acquisitions: Evidence from the telecommunications industry

I study the announcement effects of all acquisitions in the recent telecom wave on both the acquirers and their industry competitors. I find evidence of negative rival returns (? 0.55%, t-stat = 2.47) by focusing on non-horizontal acquisitions where rivals are less susceptible to experience positive returns due to increased market power or expectation that some will become future targets themselves. I find that this effect is worse for closer rivals defined as having similar size and being in the same primary service area as the acquirer. Competitor returns are positively correlated with those of the acquirers suggesting that the negative impact experienced by competitors is driven by acquisitions in which the acquirer itself is earning negative abnormal returns. Results are broadly consistent with the Competitive Advantage Hypothesis that posits acquisitions are a means of corporate restructuring in a changing environment, awarding the acquirer a competitive edge and thereby making these acquisitions costly for their non-merging competitors.     

The New Narrative: Applying narratology to the shaping of futures outputs

Both scenario development and design practices incorporate elements of storytelling, but this use remains undertheorised. This paper will draw upon literary theory, film theory and science fiction criticism to develop an analytical model of narrative structure and rhetorics which speaks to the concerns of scenario developers and designers when engaged in shaping the final outputs or deliverables of a futures project.After highlighting the differing role of telos in art and futures and defining the metacategory of “narratives of futurity”, this paper then defines the terms “story”, “narrative”, “narrator” and “world” in the literary context. It then shows how those concepts map onto futures practice, before going into detail regarding the variety of narrative strategies available across a range of different forms and media, and the qualitative effects that they can reproduce in audiences. There follows the construction of a 2 × 2 matrix based on the critical concepts of narrative mode and narrative logic, within which narratives of futurity might be usefully catalogued and compared, and from which certain broad conclusions may be reached as regards the relation between choice of medium and rhetorical effect. The implications of this analysis are explored in detail.     

Dividend privileges and the value of voting rights: Evidence from Italy

The present paper proposes a new measure of the voting right, the Relative Vote Segment, which incorporates dividend privileges into the inferior class of shares. We test and compare it against the standard Relative Price Difference and the Nenova (2003) measure using 1998–2008 data from Italy, a country where dividend privileges are relevant. Results show that when dividend privileges are considered, the average voting right equals + 35.63%, while its estimated value corresponds to a significantly lower + 20.35% and + 1.29% with the Relative Price Difference and the Nenova (2003) measure, respectively. Negative values of voting rights drop significantly with our methodology. Results become even more clear-cut when we clean the sample of possible measurement errors. As far as the determinants of the voting premium are concerned, the choice of the measure does not appear to have a significant impact, as long as the dividend differences are controlled for.     

The home bias is here to stay

Over the last 15 years, dramatically decreasing foreign investment costs have not reduced the home bias. We show that the home bias induced by a given cost is proportional to the factor ρ/(1 − ρ), where ρ is the average correlation between markets. This factor is very sensitive to the correlation, especially when the correlation is high. Empirically, correlations have been steadily increasing from 0.4 in the 90’s to about 0.9 today. Thus, the decreasing extra costs are increasingly magnified, explaining the persistence of the home bias, and predicting its continuation.     

Cross-border spillover effects of unconventional monetary policies on Swiss asset prices

Unconventional monetary policies (UMPs) announced by the Federal Reserve, the European Central Bank, the Bank of England and the Bank of Japan exert important spillover effects on asset prices in Switzerland. Using a broad UMP event set and a long-term bond-futures based measure of market anticipation, we show that surprisingly expansionary UMPs lower Swiss government and corporate bond yields, induce the Swiss franc to appreciate, and dampen Swiss equity prices. Four extensions provide further insights. First, the estimated effects are strongest for announcements by the ECB. Second, the impact on government bonds is largest for bonds with residual maturities of 7–10 years. Third, the impact of foreign UMP shocks on exchange rates and Swiss bond yields is less pronounced after the introduction of the minimum rate of 1.20 Swiss franc per Euro by the Swiss National Bank on September 6, 2011, indicating that domestic monetary policy action partially affects the impact of external monetary shocks on domestic financial markets. Fourth, the sign of spillover effects differs for positive and negative UMP surprises, but their strength does not.     

How costly is the Sarbanes Oxley Act? Evidence on the effects of the Act on corporate profitability

The Sarbanes-Oxley Act (SOX) was intended to protect investors by improving the accuracy and reliability of corporate disclosures. However, critics have argued that the costs of SOX far outweigh its intended benefits. Prior studies based on stock-price reactions to SOX-related events document mixed evidence on the expected impact of SOX. In contrast, we provide evidence on the net realized costs of SOX by examining its impact on operating profitability. We find that average cash flows decline by 1.3% of total assets after SOX. These costs are more significant for smaller firms, for more complex firms, and for firms with lower-growth opportunities. Annually, these costs range from $6 million for smaller firms to $39 million for larger firms. Further, we document that net SOX-related costs are not limited to one-time expenses associated with internal-control design and implementation. In aggregate, for the 1428 firms in our sample, these costs amount to about $19 billion per year. Profitability is lower for up to four years post-SOX. To our knowledge, ours are the first estimates of the realized net costs imposed by SOX.     

Towards an orientation of higher education in the post Rio + 20 process: How is the game changing?

The purpose of this paper is to identify and assess the implications of sustainable development for the future orientation of higher education, especially after the 2012 United Nations Conference on Sustainable Development (Rio + 20). A qualitative trend analysis is being used for this purpose, in the context of which three macro trends are combined: (1) higher education that has been developed via five periods; (2) sustainable development that has evolved through three stages; and (3) the nexus between sustainable development and higher education which has strengthened through three phases. The simultaneous analysis of the macro trends regarding their possible interactive effects (through an expert panel discussion) demonstrates that higher education and universities under the influence of sustainable development elements are entering into a new era in which the function of “higher education for sustainable development” could be interpreted as the seeds of a newly emerging mission for universities. In this regard, it is expected that the concept of “sustainable university” is likely to become more common to meet the emerging mission. Consistent with the Rio + 20 outcomes, the authors analyzed the concept of “sustainable university” and identified the fact that it is practically divided into three interrelated and complementary categories, namely social-, environmental-, and economic-oriented university in pursuit of actualizing sustainable development.     

Predictive regression with order-p autoregressive predictors

Studies of predictive regressions analyze the case where y_t is predicted by x_t ? 1 with x_t being first-order autoregressive, AR(1). Under some conditions, the OLS-estimated predictive coefficient is known to be biased. We analyze a predictive model where y_t is predicted by x_t ? 1, x_t ? 2,… x_t ? p with x_t being autoregressive of order p, AR(p) with p > 1. We develop a generalized augmented regression method that produces a reduced-bias point estimate of the predictive coefficients and derive an appropriate hypothesis testing procedure. We apply our method to the prediction of quarterly stock returns by dividend yield, which is apparently AR(2). Using our method results in the AR(2) predictor series having insignificant effect, although under OLS, or the commonly assumed AR(1) structure, the predictive model is significant. We also generalize our method to the case of multiple AR(p) predictors.     

Foreign investment with inflation-linked securities: A natural hedge under Fisher theory?

All foreign holders of U.S. dollars currencies face significant risk of unfavorable currency exchange movements, proportional to the amounts they hold. Some of these risks can be hedged to an extent, but the costs of doing so can be significant, and errors in execution or maintenance of the hedges can cause serious capital losses. Today the vast holdings of China and others creates currency risk on an unprecedented scale. China alone now has a total in excess of a trillion (1 × 10¹²) U.S. dollars, which makes traditional approaches to hedging problematic at best.¹ This paper analyzes the potential hedging effectiveness of investing foreign dollar holdings in U.S. inflation-indexed securities under Fisher's Identity. To the extent that Fisher's Identity and its derivative theories hold, foreign investors can effectively protect the purchasing power of their dollar balances, and earn an assured rate of return. Investment in inflation-indexed securities does not incur the additional expenses that swaps and currency hedges do.
