In a seminal paper on electoral equilibrium under majority rule, Ledyard (1984) demonstrates that strategic participation
by voters results in an electoral equilibrium at the proposal that maximizes the utility of a randomly selected voter. Palfrey
and Rosenthal (1985) limit the usefulness of this result by showing that strategic participation rates are miniscule in large
electorates, and that the incentive to participate vanishes completely as the electorate grows without bound. The most reasonable
modification of Ledyard’s approach that circumvents these criticisms is to allow for a negative cost of voting. We show that
when voters can have even an arbitrarily small negative cost of voting, there is an electorate sufficiently large so that
any proposal is defeated or tied by the median proposal. This observation raises questions about the existence of electoral
equilibrium under strategic participation, and is relevant to the efficiency of elections. 相似文献

Vertical integration theory has long suggested internal costs related to changes in incentives due to vertical integration, which means that vertical integration may lead to agency costs. In this work, we specify the notion of agency costs of vertical integration and extend Ang et al. (2000)'s measurement of agency costs to provide an empirical assessment of these costs in the French wine industry. Our econometric analysis finds that the agency costs of vertical integration may reach 2–3% of sales. It also showed that operating expenses of vertical integration are lower for cooperatives than for other firms, while vertical integration is less rewarding for them. This raises questions on the relation between agency costs in cooperatives and their performance. 相似文献

传统物流是指物质资源和服务信息从生产场所到消费场所的流动.本质上,在需求与供应之间的联系枢纽:产—消通道乃至超级英特网上运动着的阴流子和阳流子正是物流的量子经济概念.在未来TMS网系上,纳米制造术将大尺度物体(产品)转化为量子,在网上传送并按需配置资源,同时又根据衣食住行用等的需要,将量子还原成可以使用的消费品.也就是说,从TMS网系发射端输入产品设计模型软件包,在其接收端下载设计模型软件,便可就地取材还原产品;或同时输入产品设计模型软件包与产品纳米形式,使消费者在接收端直接下载原产品. 相似文献

The financial theory (Modigliani & Miller, 1958) rises that risk management was not an issue for companies because shareholders could make their own hedging management through portfolio diversification; however, further studies conflict with that statement and show that corporate financial hedging improves performance and increases the value thereof (Ahmed, Azevedo, & Guney, 2014; Allayannis & Weston, 2001; Allayannis & Ofek, 1998). Efficient management of market risks, which is based on the use of financial derivatives, demands strategic and efficient managers in hedging that adds value to the firm, especially in against shocks and imbalances from a macroeconomic and financial nature. Empirical evidence analyzes the performance of the Q-Tobin as an indicator of the effect of hedging strategies of exchange rate associated to the market value. This paper aims to find evidence in Colombia on the effect of using derivatives in the market value of the firm. Its added value lies in the analysis made by economic sectors, identified by CIIU codes and grouped into 5 sectors (Agricultural, Commercial, Industrial or Manufacturing, Services and Construction). The methodology includes several models estimating regression panel data, using a Pooled regression with estimators of fixed and random effects by maximum likelihood estimator. In general, it was found a premium due to hedging, statistically and financially significant, for companies exposed to exchange rate risks that use derivatives by an average of 6.3% on the market value. Moreover, mixed results were found regarding the analyzed variables in the model. 相似文献

‘Who Knows What?’ in New Venture Teams: Transactive Memory Systems as a Micro‐Foundation of Entrepreneurial Orientation

The increasing importance of entrepreneurial behaviour has led scholars to embrace the idea that an entrepreneurial orientation (EO) is an important predictor of firm performance. While EO occupies a central position in strategic entrepreneurship research, scholars have yet to explore its origins in new ventures. Drawing on the knowledge‐based and cognitive views, we theorize that a new venture team's transactive memory system is a cognitive mechanism that spurs the development of an EO. In a field study of high‐tech new ventures in China, we examined the relationship between venture teams’ transactive memory systems (representing the distribution, integration, and utilization of the teams’ knowledge) and EO and the moderating influence of team‐, firm‐, and environment‐level factors. We found that the transactive memory system of a new venture team enhanced their EO and that this relationship was positively influenced by intra‐team trust, the structural organicity of a venture, and environmental dynamism. Our findings provide novel insights into the micro‐foundations of TMS in developing an EO in new ventures. 相似文献
