Scientific methods in finance 总被引:1,自引:0,他引:1
Stephen Kane 《International Review of Financial Analysis》2004,13(1):105-118
Computer software can easily produce many financial models with technical skill, but investigators need to interpret and adapt computer output. Such analysis requires a deep knowledge of scientific fundamentals. We argue that an evidential perspective is more appropriate than a decision framework for model selection. We discuss four necessary conditions for any scientific investigation: observables, interpretables, replicables, and robustness in the context of examples familiar to finance professionals. Carefully planning the design of an experiment is the best way to address many econometric maladies. Furthermore, we emphasize the need for more sensitivity testing and for independent replication of empirical results within the finance profession. 相似文献

This paper investigates the source of momentum profits, while inferring the validity of the assumptions underlying rational and behavioural theories. Using a unique sample of securities listed in the Italian Stock Exchange from 1950 to 1995, we observe that buying better performing stocks in the previous 3-12 months and selling worse performing stocks over the same period yields significant profits in the short term (less than 1 year). Results also hold when conditioned upon different risk specifications. On the other hand, the continuation effect seems to significantly revert over a longer period. More importantly, in contrast with Conrad and Kaul [Rev. Financ. Stud. 11 (1998) 489], bootstrap and Monte Carlo simulations show that momentum profits are more likely to be generated by stock returns time series properties rather than by their cross-sectional differences. While the overall findings cannot reject the market efficiency hypothesis, we argue that behavioural theory may be a possible “story” to interpret the continuation effect. 相似文献

Section 3450 of the Canadian Institute of Chartered Accountants (CICA) Handbook requires Canadian firms to capitalize development costs that meet certain criteria and to expense those that relate to research. International Accounting Standard (IAS) No. 38 favours a similar approach. In the United States, Statement of Financial Accounting Standard (SFAS) No. 2 recommends the immediate expensing of all research and development (R&D) spending. The only exception is SFAS No. 86, which requires software development costs to be capitalized when a product successfully passes a technological feasibility test. Consequently, the Canadian financial disclosure regime provides a rich setting for testing the market valuation of capitalized R&D. Our primary research question asks whether capitalized R&D provides useful information to market participants investing in Canadian firms. We use price‐level and return models to assess the value relevance of capitalized R&D disclosed in the financial statements under Canadian GAAP. In line with expectations, using a price‐level model, we find that capitalized R&D and R&D expense as disclosed in the financial statements provide information that is value relevant to market participants. However, we find that R&D capitalized during the year helps explain returns while R&D expense does not. Thus we conclude that the application of section 3450 of the CICA Handbook produces value‐relevant information. 相似文献

Using a high-frequency data set of the spot Australian/US dollar, this study examines the distribution of quotes, spreads, and returns across the trading day. By identifying the direction of trade and the subsequent quote returns from contributing banks, the segmented nature of the market into market-makers and informed and uninformed traders is investigated. The results suggest that the economic gain possible from private information is maximised over 2 to 5 quotes and is rapidly eroded by 20 quotes (about 2 min later during busy trading times) as other new information enters the market. Also, the analysis is revealing of discontinuities in trading and the volatility of pricing across the trading day. 相似文献

This paper discusses the relationship between market orientation and organizational learning and, in particular, the former's contribution to the generation of double-loop learning. Although prior contributions on this topic have been controversial, the authors, departing from the principles of RBV, consider market orientation a resource capable of generating higher order organizational learning and, in this way, capable of additionally reinforcing firms' sustainable competitive advantage. The empirical study provides evidence on the existing relationship between a firm's learning and market orientation degree and the organization's economic and non-economic results. Findings indicate that learning orientation stimulates the market-oriented behavior and that it also positively affects the establishment of long-term relationships with strategic clients. Contrary to prior research a significant and positive effect on business performance is only contrasted in the case of market orientation. 相似文献

This paper examines the role of downward earnings management and political connection on the receipt of government subsidies and market pricing of subsidies. Using subsidies data hand-collected from Chinese listed firms over the period 2004–2014, the results show a significantly positive association between downward earnings management and the receipt of government subsidies. The results also reveal that a firm's political connection is conducive to securing subsidies for poor performers, but not for good performers. Market pricing analyses demonstrate that share markets value subsidies positively in general, but the effect is ameliorated in firms conducting downward earnings management. No discernible difference is found between the market pricing of subsidies received by firms with political connections and those without. 相似文献

This study investigates the impact of chief executive officers’ (CEO) compensation on their choices regarding the timing of earnings restatements. The results indicate a negative relationship between options exercised and lags in disclosing the restated earnings, suggesting that managers who exercise options in a given year tend to release information quickly. This effect is more pronounced if the options are exercised after the dark period. We also find that the market penalises longer lags in the restatement disclosure. It seems that the CEO would try to optimise the timing of information release so as to balance the costs and benefits. 相似文献

To overcome competition in an increasingly network dependent market, retailers are required to influence upstream channel partners while sustaining relationships. However, the contemporary supply chain literature has not sufficiently leveraged the resource and relational paradigms to examine influence. Grounded on resource dependency theory and commitment-trust theory paradigms, this study describes conceptualization and operationalization of a 12-item scale for measuring non-coercive influence on upstream channel partners in retail supply chain management (R-SCM) context. The study is based on responses from 547 retail professionals in India obtained over four successive surveys. Psychometric properties were assessed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The proposed scale demonstrates construct validity. Invariance-testing carried out over 4-levels of increasingly demanding equivalence confirmed cross-validation. Nomological validity of the scale was tested by evaluating association with suppliers’ intention to cooperate. The results indicate existence of three dimensions of non-coercive influence: collaborative intent, market intelligence dissemination, and operational support. Retailers can use the scale to assess their personnel's non-coercive influence behavior over suppliers. 相似文献

Public–private partnerships are increasingly seen as an important tool to build agri-food supply chains and develop markets for agri-food products in emerging economies. However, many of these initiatives fail when the public component of the program ends. One exception is the USDA Market Assistance Program (MAP) that facilitated the redevelopment of the Armenian dairy sector after privatization. This paper presents a case study of this initiative and hypothesize that the USDA MAP facilitated farmer investment in private enforcement capital. This investment resulted in sustainable market relationships between farmers and dairy processors even after the USDA MAP expired. We find empirical evidence to support this hypothesis using a panel dataset collected from 172 Armenian dairy farmers in 2004 and 2009. 相似文献
