We study socio-ecological models for a fishing ground open to tourists. On Jeju Island, Korea, women traditional divers called “Haenyeo” harvest resources in a common fishing ground. To investigate the impact of introducing tourists on the benefit to the fishing association and the resource level, we examine two models that differ in the way the number of tourists is controlled. In the first model, the fishing association charges an entrance fee to tourists and the level of the fee is chosen to regulate tourist number. In the second, only a part of the fishing ground is made open to tourists, and the fraction of the ground open is chosen to control the tourist number. In both models, the fishing association seeks to maximize its total benefit. Analysis shows that the way the number of tourists increases with the availability of resources strongly influences the distribution of benefits among the fishing ground stakeholders. Finally, we discuss policy implications of our results and how local government can reduce the risk of introducing tourism.  相似文献

This study empirically examines the effect of a non-traditional information source, namely a firm's blog visibility on the capital market valuation of firms. After controlling for earnings, book value of equity and other value relevant variables, such as traditional media exposure, R&D spending, and advertising expense, we find a positive association between a firm's blog visibility and its capital market valuation. In addition, we find blog visibility Grange causes trading, not vice versa. Our findings indicate that non-traditional information sources such as blogs help disseminate information and influence consumers' investment decisions by capturing their attention.  相似文献

Franchising has attracted the attention of retailing and entrepreneurship scholars in the past three decades, but evidence pertaining to how franchising affects financial performance is mixed and inconclusive. Thus, the question remains as to whether franchising firms exhibit better financial performance than non-franchising firms in the same industry. In order to find an answer to this question, our study compares the risk-adjusted financial performance of franchising versus non-franchising restaurant firms over the 1995–2008 interval, using five different performance measures: the Sharpe Ratio, the Treynor Ratio, the Jensen Index, the Sortino Ratio, and the Upside Potential Ratio. For each measure, the results revealed that franchising restaurant firms outperformed their non-franchising counterparts. Thus, we provide very robust evidence that franchising is superior on average in the restaurant industry, which can help explain the increasing popularity of franchising as a business form.  相似文献

We investigate the performance and risk of Socially Responsible Investment (SRI) equity funds in the Australian market and find no significant difference between the returns of SRI and conventional funds. In an extension to prior literature, we examine the impact of the number of positive, negative and total screens funds impose on performance and risk. We find little evidence of positive or negative screening impacting total return, but find weak evidence that funds with more screens overall provide better risk-adjusted performance. Positive screening significantly reduces funds’ risk. However, negative screening significantly increases risk and reduces funds’ abilities to form diversified portfolios.  相似文献

How do bankruptcy laws as formal institutions affect entrepreneurship development around the world? Do entrepreneur-friendly bankruptcy laws encourage more entrepreneurship development at a societal level? We posit that if bankrupt entrepreneurs are excessively punished for failure, they may give up potentially high-return but inherently high-risk opportunities to start new businesses. Amassing a cross-country database from 29 countries spanning 19 years (1990-2008), we find that lenient, entrepreneur-friendly bankruptcy laws are significantly correlated with the level of entrepreneurship development as measured by the rate of new firm entry.  相似文献
