Option strategies: Good deals and margin calls

We provide evidence that trading frictions have an economically important impact on the execution and the profitability of option strategies that involve writing out-of-the-money put options. Margin requirements, in particular, limit the notional amount of capital that can be invested in the strategies and force investors to close down positions and realize losses. The economic effect of frictions is stronger when the investor seeks to write options more aggressively. Although margins are effective in reducing counterparty default risk, they also impose a friction that limits investors from supplying liquidity to the option market.     

Spirituality,Moral Identity,and Consumer Ethics: A Multi-cultural Study

Competitor pressure is one of the major reasons that a SME engages in environmentally friendly or damaging activities. Extant research has argued that environmental strengths and concerns have mirror opposite relationships with stakeholder antecedents as well as with performance outcomes. We suggest this argument does not reflect the reality. Building on stakeholder management and Red Queen theories, we hypothesize that environmental strengths and concerns have differential relationships with competitors–firm power exchange and financial performance for Chinese SMEs. Results of ten interviews, a pretest, and a large-scale field study indicate that competitors–firm power divergence has a positive relationship with environmental strengths, yet the link between this divergence and environmental concerns does not exist. Further, environmental strengths mediate the relationship between competitors–firm power divergence and financial performance of Chinese SMEs.     

HETEROGENEITY AND THE PUBLIC SECTOR WAGE POLICY

A model with search and matching frictions and heterogeneous workers was established to evaluate a reform of the public sector wage policy in steady state. The model was calibrated to the U.K. economy based on Labour Force Survey data. A review of the pay received by all public sector workers to align the distribution of wages with the private sector reduces steady‐state unemployment by 1.4 percentage points.     

The impact of international information disclosure requirements on market discipline

Financial regulators are challenged with finding the most efficient and effective ways to monitor banks given an expanding and complex international financial system. Market discipline has grown in importance as a way to discourage banks from taking on unnecessary risk. One of the main drivers of market discipline is information disclosure. While the literature on market discipline is expansive, there are no known studies on the impact of individual information disclosure requirements on market discipline. Our study investigates which specific disclosure requirements influence financial investors to discipline banks and which do not. We find that information disclosure requirements primarily reduce or have no impact on market discipline practices.     

LIMITED ENFORCEMENT,FINANCIAL INTERMEDIATION,AND ECONOMIC DEVELOPMENT: A QUANTITATIVE ASSESSMENT*

We present a model of economic development where the importance of financial differences caused by limited enforcement can be measured. Economies where enforcement is poor direct less capital to the production sector and employ less efficient technologies. Calibrated simulations reveal that the resulting effect on output is large. Furthermore, the model correctly predicts that the average scale of production should rise with the quality of enforcement. Finally, we find that the importance of limited enforcement rises with the importance of capital in production.     

Does oil corrupt? Evidence from a natural experiment in West Africa

This paper explores the oil discovery announcements in Sao Tome and Principe (1997-1999) to assess the role of natural resources in determining corruption. For this purpose, we use a natural experiment framework which contrasts Sao Tome and Principe to Cape Verde, a control West African country sharing the same colonial past and important recent economic and political shocks. Our measurement is based on tailored household surveys we conducted in both island countries. The unique survey instrument was retrospective and used personal histories to elicit memories from the respondents. We analyze changes in perceived corruption across a wide range of public services and allocations. We find clearest increases on vote buying, education (namely in the allocation of scholarships) and customs, ranging from 31 to 40% of the subjective scale. We interpret these findings as symptoms of increased competition for core state resources.     

The Role of Ethics and Social Responsibility in Organizational Success: A Spanish Perspective

Ethics has assumed a dominant position in the current economic debate, and this study focuses on ethics as a legitimate underpinning to good business decision making. Using a self-response survey of marketing managers in Spain, the current theory on ethical decision making is extended. Results support the mediating influence of the PRESOR construct (an individual’s perception of the importance of ethics and social responsibility for the effectiveness of the organization) on relativistic and idealistic moral thinking when one is considering the moral intensity of a situation. In addition, the study found support for the relationship between relativism (negative), idealism (positive), corporate ethical values, and job satisfaction, thereby providing additional support for the prior theory. Finally, a thorough review of the extant literature and suggestions for future ethics research in the marketing field are included.     

Indigenous ecotourism in the Mayan rainforest of Palenque: empowerment issues in sustainable development

Indigenous ecotourism in the Mayan rainforest has received little research attention. This study examines issues related to the level of empowerment in a Mayan village located near the Palenque World Heritage Site in southern Mexico. An adapted empowerment framework was used to assess community empowerment and its relationship with stakeholders’ participation by collecting the views of internal and external stakeholders in indigenous ecotourism. Using a checklist of 60 empowerment indicators, the study developed a wheel of empowerment tool that graphically illustrates and compares levels of empowerment/disempowerment in local communities. Results indicate that although there is a will from many villagers to participate in tourism, lack of knowledge, limited economic resources and the poor negotiation skills of local leaders have disempowered the community from undertaking ecotourism ventures. Non Governmental Organisations (NGOs) have not supported the community until recently, the private sector has played little part, and while the Mexican government is shaping the course of indigenous ecotourism with support programmes, state agencies have resisted local ecotourism development. Overall, the community fell below the midpoint on the Wheel of Empowerment Scale. These findings show a need for more effective empowerment strategies to maximise community involvement in managing cultural and natural resources for tourism development.
