Estimation of Asymmetric Stochastic Volatility Models: Application to Daily Average Prices of Energy Products

Energy supply and demand, and as a consequence energy prices, are likely to represent one of the biggest challenges of the 21st century. Commodity markets exhibit increased volatility when there is little or no underutilized supply capability to meet natural fluctuations in demand. In the case of energy markets, the large capital requirements and significant lead times associated with energy production and delivery make them more susceptible to the imbalances in supply capability and demand. Energy price volatility has destructive impact on market agents, and this impact is intensified when the prices exhibit asymmetric volatility. This article pursues two aspects of the issue. First we consider general aspects, especially the asymmetric pattern of volatility of daily returns of different types of energy products. Then, we analyze the behaviour of daily returns by using traditional models of volatility that include AGARCH, TGARCH, EGARCH, and ARSV strategies, as well as a threshold asymmetric autoregressive stochastic volatility (TA-ARSV) model that we propose. The energy products considered in this analysis are probably the most relevant energy products for the economic activity of the nations and the economic relations between countries: Crude Oil (OPEC reference basket and London Brent index), Gasoline, Natural Gas, Butane, and Propane. We use spot prices and the time reference ranges from 1986–1993 to 2009 depending on the product.     

Volunteerism,compassion and religiosity as drivers of donations practices

• The topic of donations is one of high relevance and has been widely covered in contemporary marketing literature. It is a topic of interest to both theoreticians and practitioners alike, particularly due to its implicit links to fundraising activities and research. The reality of what makes an individual donor ultimately part with his money and give it away to a nonprofit organization is a hot contemporary topic. This study looks into the role of religiosity as a predictor of donations practices. Also volunteerism and compassion, two acts of pro‐social behaviour are analysed as predictors of donations practices. Using data collected from a survey of 612 charity donors in Portugal, the results show unequivocally that religiosity does influence donations practices, and so being a predictor of donations practices. Moreover, pro‐social behaviour is a predictor of donations practices when in the case of volunteerism, but not in the form of compassion.
• The findings are particularly useful for nonprofit organizations that want to attract and retain individual charitable donors and may also help to increase donation regularity, to obtain higher amounts, and donations both to religious and to secular organizations. Finally, it can be stated that the understanding of religiosity sheds light on knowledge about donations practices, and that this study also makes an important contribution to academia, as it is the first study conducted in Portugal that assesses the drivers of donations practices.

Distinctive Features of Environmental Innovators: An Econometric Analysis

This paper analyzes the main determinants influencing environmental innovators (i.e. firms developing or adopting environmental innovations) in Spain with respect to non‐environmental innovators. Similarly to other contributions in the literature, our results show that Spanish environmental innovators respond to regulatory stimulus in the form of demand‐pull and technology‐push instruments. They have a high internal technological capability and combine internal and external information sources, mostly in cooperation with knowledge institutions. Environmental innovators are more concentrated in mature, traditionally highly polluting sectors, but new firms are not more environmentally innovative than incumbents. Most importantly, in contrast to other environmental innovation studies, mostly carried out in a German context, we have not found evidence of a market pull from either the domestic or international markets. Furthermore, cost savings are not found to be a distinctive driver for environmental innovators. These differential results are possibly related to the special features of Spain regarding its national innovation system and the degree of stringency of environmental regulation and environmental consciousness of its consumers.

Has the CSR engagement of electrical companies had an effect on their performance? A closer look at the environment

Even though electrical companies attain a top ranking in the publication of CSR reports, they are often accused of 'green‐washing' due to their bad environmental reputation. The current economic crisis is testing their real CSR commitment more than ever, especially when this goes beyond its economic consequences. Based on a worldwide sample of electrical companies, we are going to study why companies are being socially responsible. We wish to know if it is due to the impact on the firms' performance or whether there are other motives (legitimation, improving their reputation) that lead companies to carry out these practices. We will also consider if it changes across the kind of CSR action considered. The results show that there is an economic justification beyond the socially responsible behaviour of the electrical companies. Additionally, most kinds of CSR action (community, diversity, corporate governance, product responsibility) are also carried out looking for economic rewards. However, the CSR actions oriented to the environment are mainly motivated by their need to improve their image and reverse their negative impact.

Market entry of firms with different legal forms: an empirical test of the influence of institutional factors

Drawing upon institutional theory we develop a conceptual model and investigate the determinants of market entry for worker cooperatives, publicly traded and limited-liability companies. Our results show that formal institutional conditions (i.e., mercantile legislation) influence the start-up choice of entrepreneurs regarding the legal form of their new venture. In addition, we take into account the influence of informal institutional conditions (i.e., local corporate culture) on the market entry rate of firms with different legal structures. Findings show that, while market entry is sensitive to the general economic climate, entry rates of firms with a different legal structure respond differently to the same economic conditions.

Regional variations in entrepreneurial cognitions: Start-up intentions of university students in Spain

Empirical research has recently paid considerable attention to the role of environmental factors in explaining regional variations in entrepreneurial activity. However, cognitive models have not usually included these factors in their analyses. Therefore, the main objective of this study is to identify some of the environmental cognitive elements that may explain regional differences in start-up intentions. Thus, an entrepreneurial intention model is developed, theoretically based on the planned behaviour approach, institutional economic theory and social capital theory. The empirical analysis is carried out using structural equation techniques over a sample of 549 final year university students from two Spanish regions (Catalonia and Andalusia). Results confirm that valuation of entrepreneurship in each region helps explain regional differences in entrepreneurial intentions. As expected, social valuation of the entrepreneur was higher in the more developed region (Catalonia), positively affecting perceived subjective norms and behavioural control. In Andalusia, the influence of perceived valuation of the entrepreneur in the closer environment was more important, affecting attitude towards the behaviour and subjective norms. These results explain some of the differences in the pool of potential entrepreneurs in each region. They also justify the need by public-policy decision-makers to promote more positive entrepreneurial values in relatively backward regions.     

Mixed methods studies in entrepreneurship research: Applications and contributions

Mixed methods research is becoming an increasingly popular approach in several fields. However, its application in the field of entrepreneurship has not been studied. The authors reviewed the use of mixed methods research in three entrepreneurship journals and two leading generalistic journals that publish entrepreneurship research, examining the main purposes and designs. A total of 955 articles were reviewed and 81 mixed methods studies were identified. The analysis of these articles revealed opportunities associated with the application of this approach. Mixed methods may help to improve entrepreneurship research addressing challenges emphasized in earlier studies. Suggestions on why and how to use mixed methods research are offered, and recommendations are provided to guide future mixed methods studies to advance our understanding of the entrepreneurial phenomenon.     

Lobbying on Accounting Standards: Evidence from IFRS 2 on Share-Based Payments

Lobbying is an essential part of the International Accounting Standards Board (IASB) standard-setting process. There is still much to learn, however, about key aspects of the roles played and arguments employed by various constituents when lobbying practices do occur. This paper focuses on the regulation of share-based payments. As these transactions were under-regulated before International Financial Reporting Standard (IFRS) 2, we expect that the strong debate that occurred during the 1990s resulted in conflicting opinions when this standard was under discussion. To analyse lobbying behaviour and assess its influence on the IASB's decision-making, we conducted a content analysis of 539 letters addressing the documents issued by the G4+1 and the IASB preceding IFRS 2. Consistent with the rational-choice model, our analysis of lobbying activity shows that preparers constituted the most active group, particularly when the IASB started the project, whereas participation of standard-setters increased at the end, which is more consistent with institutional theory. A common strategy was to provide arguments merely on points of disagreement. Preparers and consultants constituted the only groups using economic-consequences arguments to disagree, but later enlisted conceptual arguments as well. The IASB considered only conceptual arguments, and no interested party had a dominant influence.     

Assessing ethical behaviours in the Spanish banking and insurance industries: evidence and challenges

This study aims to improve understanding of the ethical nature of the relations in two labour-intensive industries to facilitate the creation of an ethical culture. For this purpose, the authors first review literature related to the main influences on ethical behaviour, then perform an empirical analysis of those factors using a hierarchical stepwise regression of a database of 525 banking and insurance employees. Contrary to expectations, leadership has a less important effect on ethical behaviour than other organizational factors. The results reveal several implications for improving the management of ethical behaviour in these industries.
