Traditional timing models are affected by several biases, which generate spurious timing and stock-picking coefficients. Academics have appointed different causes as the possible sources of these biases. A negative correlation between timing and stock-picking abilities arises as a consequence of the biases in traditional timing models. This article provides evidence for one bias commonly found in traditional timing models, which is related with options. We focus on this bias in view of the scant attention it has so far received in the literature. We believe one possible cause for this bias is the failure to include the cost of the option implicit in timing activities in the timing models, and on this basis, we opt for a corrected version of the Merton and Henriksson model (1981). This study therefore is a pioneer in the assessment of the magnitude of this bias and in the measurement of the impact of its correction on fund managers’ results. Our results confirm both the existence of the bias and the correction of the problem when the cost of the option is included in timing models. The modified version of the Merton and Henriksson model, unlike the traditional model, reports positive timing and stock-picking coefficients, supporting the good performance by managers. 相似文献

ABSTRACT In this article we show that the results obtained by accounting-based fundamental analysis strategies observed in the US market cannot be directly extended to emerging markets with less developed institutional environments and narrow equity markets as found in Latin America. We use Brazil as a special case and through standard tests show the apparent usefulness of financial statement analysis as an effective investment tool. We show that an investor could have changed his/her high book-to-market (HBM) portfolio one-year (two years) market-adjusted returns from 5.7% (42.4%) to 26.7% (120.2%) by selecting financially strong HBM firms listed on the São Paulo Stock Exchange. Our tests were performed using stock returns from 1995 to 2007 and financial and accounting data from 1994 to 2004. When one considers low book-to-market (LBM) firms, the results of the study indicate that an investor could change his/her mean (median) one-year market adjusted return from ?11.9% (?7.4%) to 8.1% (2.5%) by adopting the strategy proposed. However, additional investigation demonstrates that the returns generated by these strategies are significantly dependent on stock's liquidity, and when we consider only stocks where arbitrage is possible, the previous results do not hold. These findings contribute to the literature that tries to address the impact of limits to arbitrage on some well reported capital markets phenomena related to financial reporting. 相似文献

ABSTRACT This article's objective is to analyze the influence innovative organizational culture has on marketing strategy formulation and results, and how this relationship affects organizational performance. The theoretical basis lies in Menon et al.'s (1999) model. The methodology included a survey with medium to large Brazilian companies in different sectors. The final sample consisted of 153 questionnaires that were valid for analysis. Techniques for statistical analysis including singular and multivariate methods were used, from which the relationships between constructs were established by structural equation modeling. Results show a positive relationship between innovative organizational culture, the marketing strategy process, and organizational performance. However, innovative culture does not have a direct influence on performance. 相似文献

ABSTRACT This article analyzes what influences a firm's choice of strategy—why some firms stick to defensive strategies while others rely on offensive ones. With this in mind a survey was conducted on mineral sector companies associated with the Brazilian Mining Institute. The results show that the majority of companies use an offensive strategy and that some companies use more than one strategy at the same time. That is, they possess a corporate strategy and a sustainability strategy. 相似文献

Tourism is a very important tool for economic development. However, its economic effects are mainly conditioned by the level of leakage. This work defines leakage, provides an original evaluation of the entrepreneurial environment in showing that it is the one with the lowest level of leakage, and creates a new framework. It also measures leakage in an innovative way using a quantitative approach. In addition, the paper explores and shows how leakage can affect critical business factors, such as customer and employee satisfaction. The empirical study uses structural equations and data from hotels in the Valencian Region (Spain) to show how important leakage is in making businesses more competitive. The results confirm the new model and are of interest for company managers and public organizations. 相似文献

We present the results of eight models that differ with respect to the time behavior of technical inefficiency and the presence of country heterogeneity. When taken into account, heterogeneity raises average technical change estimates, however technical progress rankings become counter-intuitive. 相似文献

The main objective of this paper is to analyse the competitiveness of the main maritime Port sited in Portugal - Port of Sines. This paper is developed under the resource-based view approach. A literature review about the resource-based view is presented with a special highlight on the contribution of organisation owns' resources to the competitiveness. With this study we intend to emphasize the applicability of a management theory to a different type of organisation which only recently starts to be preoccupied with its competitiveness. A case study methodology is used in order to collect all information needed about its main resources and capabilities of Port and also its competitiveness. The resources analysed in this paper are: The infrastructures, the accessibilities, the Port operations and also the information systems used on it. Also, a set of performance data is analysed as the main indicators of competitiveness. After that, a conceptual model is presented in order to systematise the main resources and capabilities under which the competitiveness of the Port of Sines is built on. 相似文献

Board independence, firm performance and ownership concentration: Evidence from Chile 总被引:2,自引:0,他引:2
What determines the composition of companies' boards in the context of high ownership concentration? Are independent directors important as an internal governance mechanism in companies with high ownership concentration? Do markets favor companies whose controlling shareholders use voting rights to elect professional directors?Using a four-year, 160-company panel data, and controlling for endogeneity, this paper addresses these three related questions, finding that an increase in the proportion of outside directors affects company value. The paper also finds that companies that present more exacerbated agency conflicts tend to incorporate professional directors to the boards, in an effort to improve corporate governance and ameliorate the agency problem. 相似文献

Consumers’ perception of, and satisfaction with, fruit quality is an important issue for both public policy and commercial reasons. However, because of information problems, consumers cannot easily choose fruits of a quality most likely to satisfy their preferences and health needs. The research reported here employed an experimental auction method to test perceptions of fruit quality by evaluating the willingness to pay (WTP) of consumers for five different varieties of soft citrus under three different information conditions: visual inspection of the fruit before peeling; visual inspection after peeling; and after consumption. Significant differences were found in valuations of the different varieties as consumers gained information. Conclusions are drawn about the value of the methodology and the results themselves, and implications are inferred for policy and for growers and traders. It is argued that product information should be oriented not just towards nutritional education but also towards increasing the pleasure of healthy eating. 相似文献

This paper studies, for the first time, socially responsible (SR) mutual fund exits. We analyse a sample of 534 U.S. SR equity mutual funds in the period 2003–2017, in which 182 exit events occurred (53 liquidations, 109 mergers within the same family, and 20 mergers across different families). The results obtained indicate that both liquidations and mergers are more likely among smaller funds that suffer net money outflows in the previous year to the event. At the family level, mergers are more frequent in outperforming families with a larger number of funds, whereas liquidations occur in families with a lower number of funds. When comparing mergers within the same family with mergers across different families, we observe that the former share more drivers with liquidations than the latter. In addition, we observe that religious and environmental funds are more likely to suffer exit events than other SR fund types. Finally, other interesting findings point out that mergers financially benefit investors in merged SR mutual funds and the financial outcomes of acquiring fund investors are not jeopardized. 相似文献
