基于引入理想决策单元DEA的公租房配租方法研究

摇号是目前重庆公租房分配的唯一形式,由于不能区分谁更迫切地需要公租房的问题,不能更好地解决分配公平的问题,本文在建立申请人状况的评价指标系统基础上,采用引入理想决策单元的数据包络分析模型,考虑申请人的困难状况对申请人进行评价和排序,以比摇号更公平的方式分配公租房,这在目前公租房数量较少的情况下有更现实的公平意义.

Criteria used by venture capitalists to evaluate new venture proposals

A questionnaire was administered to one hundred venture capitalists to determine the most important criteria that they use to decide on funding new ventures. Perhaps the most important finding from the study is direct confirmation of the frequently iterated position taken by the venture capital community that above all it is the quality of the entrepreneur that ultimately determines the funding decision. Five of the top ten most important criteria had to do with the entrepreneur's experience or personality. There is no question that irrespective of the horse (product), horse race (market), or odds (financial criteria), it is the jockey (entrepreneur) who fundamentally determines whether the venture capitalist will place a bet at all.The question is if this is the case, then why is so much emphasis placed on the business plan? In a business plan there is generally little to indicate the characteristics of the entrepreneur—it is generally devoted to a detailed discussion of the product/service, the market, and the competition. To us, the implications are obvious—such content is necessary, but not sufficient. The business plan should also show as clearly as possible that the “jockey is fit to ride” —namely, indicate by whatever feasible and credible means possible that the entrepreneur has staying power, has a track record, can react to risk well, and has familiarity with the target market. Failing this, he or she needs to be able to pull together a team that has such characteristics and show that he or she is capable of leading that team.Factor analysis of the results indicate that venture capitalists appear to assess ventures systematically in terms of six categories of risk to be managed. These are: risk of losing the entire investment: risk of being unable to bail out if necessary; risk of failure to implement the venture idea; competitive risk; risk of management failure; and risk of leadership failure.Finally, three clusters of venture capitalists were identified: those who carefully assess the competitive and implementation risks: those who seek easy bail out; and those who deliberately keep as many options open as possible.     

Entrepreneurial orientation and firm performance: The role of knowledge creation process

This study examines the relationships among entrepreneurial orientation, knowledge creation process, and firm performance using survey data from 165 entrepreneurs. We use LISREL analysis to test the direct and indirect effects of the entrepreneurial orientation on firm performance. Knowledge creation process - operationalized to reflect the dimensions of socialization, externalization, combination, and internalization - is used as the mediating variable for explaining the relationship between entrepreneurial orientation and firm performance. The results indicate that the significance of the direct effect of entrepreneurial orientation on firm performance is reduced when the indirect effect of entrepreneurial orientation through knowledge creation process is included in a total effect model. Consequently, entrepreneurial orientation is positively related to firm performance, and knowledge creation process plays a mediating role in this relationship.

Trade liberalization, foreign ownership, and the environment in a small open economy

This paper examines the effects of trade liberalization on firm ownership and the environment for a small open economy. It is found that trade liberalization via tariff reductions can result in a dramatic switch in firm ownership from domestic to foreign, coupled with a lower pollution tax.     

Entrepreneurial Structure Qualitative Analysis: The Case of Seville (Spain)

In the field of territorial economic growth, it is possible to identify important characteristics in the entrepreneurial structure, such as the structure of the size of firms, main activity sectors, or the degree of innovation. However, other lesser known characteristics are important also, such as functional dependency, which considers the relationship between small and medium enterprises (SMEs), and suppliers and clients belonging to any territorial field or productive dependency, which considers the level of concentration in terms of buying and selling in connection with the main suppliers and clients, respectively. In order to empirically contrast the importance of these entrepreneurial characteristics and try to relate them with territorial economic growth, a sample of 400 enterprises in the province of Seville (Spain) is used.      

Induced innovation and land degradation: Results from a bioeconomic model of a village in West Africa

This paper introduces a modeling method which simulates a village's response to population and market pressure. The method combines a recursive and dynamic linear programming model with a biophysical model of soil condition and plant growth that predicts yields and land degradation for different type of land, land use and cropping patterns. The linear programming model simulates farmers' plans aggregated at the village level under constraints of risk aversion, food consumption, land area, soil fertility, soil depth, labor and cash availability. Detailed agroecological factors determine Ihe main processes of land degradation. A large number of technological alternatives, representing different degrees of labor and/or land-saving techniques available in the study areas, are introduced, taking into account their respective constraints, costs and advantages. The method has been calibrated for a village located in the sub-humid region of Burkina Faso. Several simulations are carried out to the Year 2030. The results show that population pressure leads to intensification and investment in land conservation practices out not necessarily to better farm incomes. Increasing market opportunities can play a more positive role in boosting productivity, but for the next decades the best way to increase production per farmer is to let farmers migrate from the high-population-density areas to the low-population-density areas because, under the current economic conditions of most Sahelian countries, intensification per hectare is stil more expensive than the fallow system.     

关于建立环境污染健康保障基金的构想

Can entrepreneurial firms benefit from product piracy?

We examine the potential benefits of product piracy to entrepreneurial firms. Specifically, we use a resource-based perspective to show that a decrease in the inimitability of an entrepreneurial firm's intellectual property does not necessarily diminish performance when piracy increases the value of this resource, and an information economics perspective to explain why and when imitation can increase the value of an intellectual property resource. This explanation reconciles empirical studies that indicate mixed results. It also expands the resource-based view by suggesting that reducing the value of one resource can directly increase the value of another.
