This research work analyzes the yields of the exchange rate parities of the American dollar, Canadian dollar, Euro, and Yen; estimates the basic statistics and the α-stables; carries out the Kolmogorov–Smirnov, Anderson–Darling, and Lilliefors goodness of fit tests; estimates the self-similar exponents and carries out the t and F tests, ruling out that the series of parities are multifractal. It also estimates the confidence intervals of the exchange rate parities and concludes that the estimated α-stable distributions are more efficient than the Gaussian distribution to quantify the risks of the market, and that the series are self-similar. Through the ? index, we can infer the risk of the events, indicating that the parities are anti-persistent and thus have short-term memory, mean reversion, and a negative correlation with the high risk in the short and medium term. The estimation and validation of the α-stable distributions and the self-similar exponent are important in the evaluation and creation of innovative investment instruments through financial engineering, risk administration, and the evaluation of derived products. 相似文献

The restaurant sector is one of the fastest growing sectors within the Spanish economy and looks likely to continue its development into the future. The implementation of total quality (TQ) systems in the tourist industry is still a recent phenomenon in Spain. Hence the importance of the client's satisfaction, resulting in the acquisition of an optimum quality level: i.e. cooking is culture and it has to be culturally adapted and promoted. The survey on the customers of Spanish restaurants reported in this article has gathered the perception of quality according to a likert scale from one to five. The objective of the survey was to determine the degree of satisfaction as well as the quality of the establishment, by using a cluster analysis of the data. Amongst the findings of the survey was the importance of the motivation of pleasure that makes people go to restaurants and it is therefore necessary to create a favourable atmosphere of quality the customers will want to come back to. This provides the sector's greatest challenge. 相似文献

Venture Capital in Spain by Stage of Development 总被引:1,自引:0,他引:1

This paper examines the investment decisions of 51 Spanish venture capital firms by stage of development. The results showed that venture capitalists ranked evaluation criteria related to the characteristics of the entrepreneurs, manager background, and management team experience as more important than market and product characteristics. Factors affecting the required rate of return were more important for the early-stage firms than for late-stage firms. Discounted cash flow analysis is the most frequently used valuation method. Private venture capital firms invest more during late development stages, while public venture capital firms invest more during the early stages. The results can be used by firms seeking venture capital, venture capital firms, consultants, and support agencies that provide capital-acquisition assistance. By gaining insight into decision criteria and processes, firms can develop better and more targeted materials to attract capital. Venture capital firms can use the information from this study to better understand their decision processes, individually and relative to competitors. Consultants and support agencies can use the information to provide better advice to both firms and venture capital firms. Information is this study could easily be built into training programs for both new and existing businesses. Finally, the results can also be incorporated directly into university courses that include material related to venture capital. 相似文献

This is an introductory paper for this Special Issue on Web 2.0 Social Capital. We present a general discussion of motivations for and barriers to applying an Enterprise 2.0 approach. Focus then shifts to the specific fields of knowledge sharing and e-commerce. The article continues with an examination of social capital 2.0 issues. Discussion centers on the employee’s perspective of using Web 2.0 applications and on the adoption of corporate Web 2.0 tools for collaboration. Finally, the paper presents a brief background for each of the topics covered in the five articles selected for this special issue on Web 2.0 social capital. 相似文献

In this study, we investigate the effects of entrepreneurial human capital on SME performance using data on 2,713 SMEs within
the European Union. Performance was measured in two ways: profitability as ROA and productivity as revenue per employee. Results indicate that both profitability and productivity are positively related to industry-specific
knowledge possessed by the CEO-owner prior to starting up the firm and the general business knowledge acquired once the firm
is up and running. Experience as a result of having previously worked in a firm in the same industry before starting a business
was related to productivity, but there is no relation with profitability. There is a link between performance and inclusion
of other CEO-owners in the founder’s inner circle of advisors. This relationship is positive when the advisor’s venture has
experienced failure and negative when the advisor’s venture has been successful. We discuss the significance of these findings
for research and practice. 相似文献

This research analyzes the impact of control by dominant institutional owners (banking institutions and investment funds) on firm value. The analysis considers the level of voting rights in the hands of the dominant institutional owner and other large shareholders. The results reveal a different effect on value depending on whether the dominant institutional investor is a banking institution or an investment fund. Moreover, the results show that the presence of other large shareholders affects firm value when a dominant institutional owner controls the firm. 相似文献
