We examine risk profiles of the Portuguese stock market index component stocks using a novel approach to the classical capital asset pricing model (CAPM). Specifically, we estimate the CAPM via fractal regressions that allow studying the marginal effects at selected scales. In this way, we can reveal whether the risk is perceived differently by market participants with different investment horizons. Apart from the analysis itself, we provide new statistical insights into the issue of separating and comparing the scale-specific effects with statistical validity. We find several stocks deviating from an expected risk perception homogeneity across investment horizons. This is true for both analysed periods, i.e. before and after the global financial crisis. There are also several stocks that changed their relationship to the market portfolio in between, which has strong implications for possible portfolio construction. The proposed methodology is not limited to financial topics but can be used in any discipline where the scale-specific marginal effects might be of interest.  相似文献

There is currently a renewed surge of interest in informal entrepreneurship around the world. One of the motives stems from how such entrepreneurship shapes and influences a substantial part of the global workforce. However, we may also verify how a major proportion of the research in this field focuses on developing economies and thus justifying the application of such analytical approaches to countries with different levels of economic development as is the case with Europe. Our research objectives, on the one hand, involve analysing the impact of R&D investment on informal entrepreneurship and, on the other hand, the moderating effect of the level of economic development on their innovative capacities and informal entrepreneurship results. To this end, and in accordance with Global Entrepreneurship Monitor, we divide the countries of Europe into two stages of development and may report that the higher the level of economic development, the greater the innovative capacity and, furthermore, the lower informal entrepreneurship becomes. The same holds for R&D investment with its increase being inversely proportionate to informal entrepreneurship. We, therefore, seek to contribute toward a better understanding of the problematic framework of informal entrepreneurship, in particular in the European context.  相似文献

This study develops a taxonomy of international service firms from an emerging market, Brazil, and assesses whether there are significant differences in international performance between the groups. After an extensive literature review, a survey was carried out with a sample of international service firms located in an emerging economy, Brazil. Using as a departure point two theoretical perspectives, the internationalization process theory and industrial organization theory, in addition to service dimensions extracted from the empirical service management literature, the study identifies four groups—large traditionals, generalist neophytes, solitary traditionals, and daring differentiators—based on firm characteristics, international services delivered, internationalization process characteristics, and international strategies adopted. The findings suggest that there are significant differences in performance between the groups.  相似文献

The external business environment is a major determinant of which sources firms select to obtain financial capital. We examine how the regulatory, political, and financial dimensions of the institutional environment influence the extent to which firms rely on informal sources of financial capital. The analyses of data from 2869 firms in twenty-six transition economies in Central and Eastern Europe (CEE) indicate that ineffective regulatory system, underdeveloped financial system, and government corruption are strong determinants of firms' reliance on informal channels for financial capital. We also find that smaller firms are more vulnerable when the local financial system is underdeveloped and the regulatory institutions are less effective in these transition economies. A subgroup analysis of firms' forms of establishment shows that private firms are sensitive to the level of development of the local financial system and state-owned enterprises are particularly sensitive to the degree of corruption.  相似文献

This paper analyses the relationship between politics and performativity of economics in the emergence of markets for biodiversity offsets. While the role of economics in constructing markets has been demonstrated by sociology and social studies of science, it has also become apparent that politics plays an important role in the material outcome of economic experiments. Two case studies of the creation of markets for biodiversity offsets are analysed, in the United States and England. The findings suggest that the creation of both markets is rooted in the language, concepts and models of economics. Politics, on the other hand, functions as a mediator of the material expression of those models. Through this mediation effect, similar economic models are performed differently, resulting in a variety of markets. This suggests that the material outcomes of processes of market creation are not defined at the outset, but can be influenced by political processes.  相似文献

The Basel Capital Accord (pillar 3) states that disclosure of information (transparency) is essential to financial stability. This study analyzes, through inflation reports, the disclosure of information from the Central Bank of Brazil concerning the credit market. We consider credit risk and capital buffers as measures of financial stability in this analysis. Furthermore, in order to measure the perception of the monetary authority on the credit market, we built two indices based on the central bank’s communication on credit development. We performed a panel data analysis based on a sample of 125 banks for the period from June 1999 to September 2014 (7000 observations). The findings suggest that central bank communication regarding expectations concerning the credit market contributes to financial stability. Therefore, this kind of communication of central banks (about credit development) may constitute an important macroprudential tool to improve financial stability.  相似文献

This study seeks to identify the antecedents of women’s entrepreneurial orientation (EO) and exploring what possible relationships that may exist between them. The research focuses on women entrepreneurs and non-entrepreneurs in a quantitative perspective whose methodology consisted of the collection of primary data through a survey distributed to women in Portugal. After structural equation modelling was applied, the results suggested that recognition of opportunities influences EO. This influence is expressed both directly and indirectly through training in management and entrepreneurial skills. These findings led to the conclusion that policies promoting training for community members, in general, need to be rethought and policies need to emphasise training in management that enhances entrepreneurial skills, thereby increasing the proliferation of entrepreneurship. Entrepreneurship education and training should be promoted from basic education onwards in order to develop entrepreneurial skills from an early age. Prior to this study, the relationships between opportunity recognition, management training and entrepreneurial skills have never been studied in relation to women.  相似文献

A lack of empirical studies on Supply Chain Risk Management (SCRM) is observed, especially in the industries of large projects. Therefore, this paper conducts a risk analysis on the Brazilian Shipbuilding Industry by generating an initial risk profile. A panel was conducted with executives from major shipyards, and the primary risks were identified, assessed, and evaluated. Findings corroborate the academic literature, reinforcing that companies recognise the importance of SCRM, but the concept is incipient and far from being successfully implemented in real life. Despite the fact that the shipyards identified important risks, the focus was on internal factors. Because the industry was exposed to risks from the external environment, no risk mitigation actions existed, resulting in the bankruptcy of many shipbuilders. This research is an initial step toward investigating SCRM techniques, offering academics a novel empirical approach that can serve as a systematic risk management tool for supply chain planning.  相似文献
