本文是Stuart W.Bunting,Muki Shpigel发表于Aquaculture 2009年294期43~51页"Evaluating the economic potential of horizontally integrated land-based marine aquaculture"一文的译文。原作者通过研究得出:生物经济模型有助于横向一体化水产养殖系统的优化,帮助澄清情况,找出关键制约因子和具有针对性的研究及发展重点。生物经济模型的其他横向一体化战略,例如对虾与贝类、海藻和红树林湿地一体化养殖,可以说明这种做法在经济上可行并满足生态无害和对社会负责。同时,生物经济模型应辅以市场分析,包括消费者评估、质量安全评估、伦理审查、环境影响评估以及与利益相关者的共同评估。 相似文献

I study a screening game in a competitive insurance market in which insurance customers differ with respect to both accident probability and degree of risk aversion. It is shown that indifference curves of customers may cross twice; thus the single crossing property does not hold. When differences in risk aversion are sufficiently large, firms cannot use policy deductibles to screen high-risk customers. Types may be pooled in equilibrium or are separated by raising premiums above actuarially fair levels. This leads to excessive entry of firms in equilibrium. 相似文献

The Consequences of Appointment Methods and Party Control for Telecommunications Pricing 总被引:1,自引:0,他引:1
While the economic approach to the politics of regulation emphasizes the importance of organized economic interests in shaping policies, political institutions in which regulatory agencies are embedded may also have significant effects. By including both economic influences and characteristics of political institutions in a model of price setting by state regulators, this paper demonstrates that both shape regulatory behavior in the telecommunications industry. Whether commissioners are elected or appointed, whether they face confirmation by a legislature, and whether a single party controls both executive and legislative branches of state governments influence the level of prices charged for basic services. 相似文献

The IT (information technology) standardisation landscape is characterised by the increasing importance of private standard setting consortia, a greater convergence between the structural features of formal and private standard organisations, and greater diversity in standard organisations. Institutional theory has been applied to explain the convergence of standard setting bodies. This paper applies institutional theory to four studies of standards organisations, showing that there are indeed homogenising mimetic, coercive and normative forces in standard setting that lead to the convergence of emergent organisations with the institutional features, but that there are also forces promoting heterogeneity, in particular the multiplicity of institutional fields within which standards consortia operate, leading to a complex, and often conflicting, matrix of institutional norms to be accommodated. 相似文献

The initial public offerings (IPOs) of diversified firms, those reporting more than one business segment at the time they go public, experience less underpricing than do IPOs by focused issuers. We explore two explanations for this phenomenon. Diversification may benefit IPO firms by reducing information asymmetries and therefore, lowering underpricing costs. Alternatively, high quality focused firms may be signaling their value by underpricing their shares to a greater degree. Though we find at least some evidence consistent with each explanation, a majority of the evidence favors signaling. 相似文献

Online apparel shopping is popular among women, with possible negative body image consequences, particularly when the website imagery is body-focused. We investigated both correlational and experimental effects of online apparel shopping on women's (N = 113) explicitly and implicitly measured self-worth, appearance attitudes and body gaze behaviour. Self-reported online apparel shopping behaviour positively correlated with self-objectification and a tendency to value and compare one's appearance. Following a simulated online shopping activity, women who browsed a body-focused activewear website felt worse about their looks, when compared with women who browsed a non-body-focused casualwear website. The activewear condition also primed lower subsequent visual attention towards female bodies in a gaze task, when compared with the casualwear condition. Given that women tend to naturally gaze at faces, the deprivation of facial stimuli in the activewear condition presumably led to a compensatory gaze effect, whereby subsequent attention towards bodies was comparably low. Importantly, dollars spent in the activewear condition correlated positively with appearance comparison and body shame attitudes. These results suggest that online apparel imagery exposure may negatively impact women's well-being. We also find evidence suggesting that gaze behaviour plays a role in how apparel marketing influences subsequent attention. 相似文献
