The hourly and daily dummy variables in the conditional variance functions of the two European currencies, the British pound and the euro are estimated. The conditional variance functions are specified as GARCH models to capture the time-dependent conditional heteroskedasticty at both the hourly and daily recorded data. The estimated dummy variables give remarkably similar and distinct characteristics of the volatility dynamics embodied in the two currencies. Some discussion of the possible sources of the observed volatility dynamics in the two currencies is provided. A comparison between GARCH, FIGARCH and SV models is also provided. The estimated hourly and daily dummy variables suggests that euro is considerably more volatile when compared to British pound, a result with important implications for the economic policy making in the two regions. 相似文献

A number of recent papers have focused on testing the linearity restrictions implied by international asset pricing models. The tests, however, have not addressed an additional restriction implied by the models; namely, that the risk premium on the world portfolio is positive. This study provides a direct assessment of this restriction. The evidence indicates that the ex ante world market risk premium can be negative. The results are robust to market proxies that are hedged and unhedged with respect to currency risk. Subperiod analysis indicates that the rejection of the positive risk premium restriction is driven by the first half of the sample period. 相似文献

On the determinants of Original Sin: an empirical investigation 总被引:1,自引:0,他引:1
Most countries do not borrow abroad in their own currency, a fact that has been referred to as “Original Sin”. This paper describes the incidence of the problem and makes an attempt at uncovering its cause. The paper finds weak support for the idea that the level of development, institutional quality, or monetary credibility or fiscal solvency is correlated with Original Sin. Only the absolute size of the economy is robustly correlated. The paper also explores the determinants of a country’s capacity to borrow at home at long duration and in local currency. It finds that monetary credibility and the presence of capital controls are positively correlated with this capacity. 相似文献

This study explores the impact of ambiguity on returns of both individual stocks and stock portfolios in an emerging market setting. First, an ambiguity index is derived and then the sensitivity of stock returns to ambiguity is analyzed while controlling for the other risk factors commonly cited in the literature. Results show that stocks with a high (low) sensitivity to ambiguity generate higher (lower) excess returns. These results are intuitive in the sense that investors seem to ask for lower returns from those stocks that serve as a natural hedge against ambiguity. Our findings are also in line with the earlier studies that provide similar evidence from the US stock markets. 相似文献

If major groups of financial reporting participants differ in their perceptions of standards for financial reporting quality, such as 'true and fair view', 'present fairly' and 'fair presentation', a financial reporting expectation gap may occur. This article reports the results of a survey designed to explore this potential gap by determining New Zealand financial directors', auditors' and shareholders' perceptions of terms associated with financial reporting quality.
The results show that a clear majority of all three groups share similar perceptions of the 'true and fair view'; but perceive 'true and fair view' to be quite different from 'fairly presents' and 'fair presentation', terms the New Zealand Institute of Chartered Accountants' (2005) describes as equivalent to 'true and fair view'. Thus there appears to be a perception gap between the respondents surveyed and the Institute. The findings also support a literal rather than a technical interpretation of 'true and fair view'; that respondents do not perceive 'true and fair view' as compliance with GAAP; and that 'true' ('truth' in accounting), the word separating 'true and fair view' from terms that include only 'fair', may be perceived as a key factor required for financial reporting quality. 相似文献

This study examines three issues: (1) the effect of information asymmetry on the budget negotiation process, (2) the effect of information asymmetry on budgetary slack when budgets are set through a negotiation process, and (3) whether subordinates consider superiors imposing a budget following a failed negotiation as being low in procedural justice, which in turn causes low subordinate performance. The results suggest that smaller differences in initial negotiation positions do not indicate a higher likelihood of agreement when initial differences are due to differential information symmetry. Further, information asymmetry affects the relationship between negotiation agreement and budgetary slack. Last, inconsistent with a pure economic perspective, having superiors impose a budget after a failed negotiation causes justice or fairness considerations to demotivate subordinates. 相似文献

We examine private issuance of public equity (PIPE) in China, and our results suggest that PIPE investors benefit from the price manipulation before and after issuance. These investors tend to cash out after lockup expiration and make large profits. We also find evidence that the trading of PIPE investors after lockup expiration is informed. Tests about the abnormal returns in the 3 years after lockup expiration suggest that at least part of the benefits PIPE investors receive come from wealth transfer from outside investors. Overall, PIPE issuers in China seem to use an opaque mechanism to compensate PIPE investors. 相似文献

This paper analyses the impact of different regulation and supervision approaches, as well as deposit insurance schemes, on the development of financial cooperatives in developing countries, using random and fixed effects estimators. Information on laws regulating financial cooperatives, the supervisory approaches adopted, and deposit insurance schemes in sixty-five developing countries were collected—mostly—from original legislations for the period 1995–2014. Key findings suggest that indicators of financial cooperative development are positively correlated with the existence of a specialized regulation; supervision under non-bank financial supervisory authorities; and the presence of deposit insurance schemes, while general cooperative society’s regulations and banking regulations are negatively correlated with financial cooperatives’ indicators. These results are robust after controlling for economic and institutional factors as well as potential endogeneity bias. 相似文献

This paper examines the relation between the replacement of mutual fund managers and their prior performance. Using the growth rate in a fund's asset base and its portfolio returns as two separate measures of performance, I document an inverse relation between the probability of managerial replacement and fund performance. The sample of departing fund managers exhibits higher portfolio turnover rates and higher expenses relative to an objective-matched sample of nonreplaced fund managers. The overall evidence is consistent with the presence of well-functioning internal and external market mechanisms for mutual fund managers. 相似文献

This article investigates the relevance of the inclusion of non-traditional activities in the specification of banks' output on the efficiency of Indian banks. The results indicate that the exclusion of non-traditional activities not only understates the cost, technical and allocative efficiencies of individual banks but also affects the ranking of ownership groups in the industry. In particular, when a proxy for non-traditional activities is accounted for in the output specification, the foreign banks appear to be more efficient than public and private sector banks. Overall, the results reinforce the prevailing view in the extant literature that the exclusion of non-traditional activities causes misspecification of banks' output, and may distort the efficiency estimates. 相似文献

Pricing derivatives goes back to the acclaimed Black and Scholes model. However, such a modelling approach is known not to be able to reproduce some of the financial stylised facts, including the dynamics of volatility. In the mathematical finance community, it has therefore emerged a new paradigm, named rough volatility modelling, that represents the volatility dynamics of financial assets as a fractional Brownian motion with Hurst exponent very small, which indeed produces rough paths. At the same time, prices’ time series have been shown to be multiscaling, characterised by different Hurst scaling exponents. This paper assesses the interplay, if present, between price multiscaling and volatility roughness, defined as the (low) Hurst exponent of the volatility process. In particular, we perform extensive simulation experiments by using one of the leading rough volatility models present in the literature, the rough Bergomi model. A real data analysis is also conducted to test if the rough volatility model reproduces the same relationship. We find that the model can reproduce multiscaling features of the prices’ time series when a low value of the Hurst exponent is used, but it fails to reproduce what the real data says. Indeed, we find that the dependency between prices’ multiscaling and the Hurst exponent of the volatility process is diametrically opposite to what we find in real data, namely a negative interplay between the two. 相似文献

We study the relationship between order flow and volatility. To this end we develop a comprehensive framework that simultaneously controls for the effects of macro announcements and order flow on prices and the effect of macro announcements on volatility. Using high-frequency 30-year U.S. Treasury bond futures data, we find a statistically and economically significant relationship between the absolute value of order flow and volatility. Moreover, this relationship is robust, inter alia, to a number of factors including the introduction of liquidity effects, use of data measured over a different frequency, and market conditions. 相似文献

When compared with its prior performance, the year 2001 is not one of the best years for the Neuer Markt. The Neuer Markt's reputation has been marred by the practice of several companies on the exchange that have published misleading information in the form of incomplete annual and quarterly data. In this study, we examine the quality of Neuer Markt quarterly reports by concentrating on the disclosure level of 47 Neuer Markt companies' reports for the third quarter of 1999, 2000, and 2001. To enable making comparisons, we have established four disclosure indexes that measure each report's compliance with the Neuer Markt Rules and Regulations (NM Rules and Regulations) as well as with International Accounting Standards (IAS) and U.S. Generally Accepted Accounting Principles (U.S. GAAP) interim reporting standards. We then attempt to find typical attributes of Neuer Markt enterprises that provide high or low level of disclosure accounting information in their quarterly reports. The results demonstrate that the level of disclosure has increased over time, partly in response to additional enforcement. In this regard, the quarterly reports standardization project of Deutsche Boerse is an important landmark in satisfying investors' information needs. 相似文献

This paper empirically investigates the x-efficiency (technical and allocative) in Australian banks. A non-parametric method of Data Envelopment Analysis (DEA) has been used to arrive at the efficiency scores. Banks in this sample were found to have low levels of overall efficiency compared with the banks in the European countries and in the US. The results indicate that, as a source of overall inefficiency, the technical component was more important than the allocative component. Thus, the inefficiency in Australian banks can be attributed to wasting of inputs (technical inefficiency) rather than choosing the incorrect input combinations (allocative inefficiency). Domestic banks were found to be more efficient than foreign owned banks. The study has important implications such as guiding the government policy regarding deregulation and mergers. Since the study pinpoints the sources of inefficiency, it would also help banks with strategic planning. 相似文献

This paper investigates the return–liquidity relationship on one Middle East and North Africa frontier market, the Tunisian Stock Exchange (TSE). The findings provide evidence that there is a significant and positive premium for companies with high price impact and low trading frequency. However, Tunisian investors appreciate more low spread stocks. We show, also, a non-linear relation between potential delays of execution and stock returns. In addition, we find that Tunisian investors require a premium to compensate past cumulative illiquidity risk (high price impact, low turnover and high potential delay of execution) over the prior three to 12 months and to compensate past cumulative spread over 12 months. We point out also that these effects are seasonal. 相似文献

We investigate the link between distress and idiosyncratic volatility. Specifically, we examine the twin puzzles of anomalously low returns for high idiosyncratic volatility stocks and high distress risk stocks, documented by Ang et al. (2006) and Campbell et al. (2008), respectively. We document that these puzzles are empirically connected, and can be explained by a simple, theoretical, single-beta CAPM model. 相似文献

The aim of this paper is to estimate multivariate affine generalized distributions (MAGH) using market data. We use the Ibovespa, CAC, DAX, FTSE, NIKKEI and S&P500 indexes. We estimate the univariate distributions, bi-variate distributions and six-dimensional distribution. Then we assess their goodness of fit using Kolmogorov distances. As an application we study the efficient frontier. 相似文献

Writing an option is a taxable event for Australian investors. This method of taxation penalizes investors who hold open short option positions over the tax year end by accelerating their tax liability relative to the timing of the economic gain from writing options. This paper examines the levels of open interest in the Australian Stock Exchange over the change in financial year to determine whether investors time their transactions to avoid this tax acceleration. The results show that level of open interest is lower in the last month of the financial year after controlling for non‐tax determinants of option demand. 相似文献
