This paper examines the impact of deregulation on thedemand for casino gaming in Atlantic City. Specifically, the paper analyzes the impact ofexpanded operating hours and floor space devoted toslot machines. Using monthly win data between June1978 and July 1996, the analysis reveals that expandedfloor space had a significant, positive impact on win,resulting in an average monthly increase of over \$2million. This shows the importance of developing aregulatory structure rigid enough to ensure thehonesty and integrity of the gaming industry, butflexible enough to allow management to respond tochanging market conditions. 相似文献

本研究梳理了社区与社区银行的概念,通过对14组代表性定义的内容分析和编码发现传统社区银行的实质就是中小型商业银行。社区隐含了社区银行的覆盖范围、服务对象和业务特征,其服务对象没有实质差别。研究提出了社区银行的四个维度和特征,分别是银行规模、覆盖范围、服务对象和业务种类。监管机构和美国提出者更关注银行规模,而研究者特别是中国研究者更重视覆盖范围。因此,“地理范围论”和“资产规模论”基本成立,而“国别论”理论差别不大,“所有制论”和“形态论”并不成立。通过案例研究和实地调研归纳出社区银行的三种主要模式:即美国的“关系信贷”、澳大利亚的“特许经营”和中国的“金融生态”模式。其中,“特许经营”模式变相扩大了银行规模和覆盖范围两个维度,而“金融生态”模式扩展和丰富了银行规模、覆盖范围和业务种类。最后,结合发达国家的先进经验,有针对性地提出四点建议,并构建了中国社区银行建设的特征与要素模型。 相似文献

不同国家、不同历史时期的特大城市人口规模变动极大,运用 Kernel 密度函数对中国城市人口规模分布的分析表明,当前以城区常住人口“500万以上”为特大城市的划分标准是合理的。从城市人口规模变动的动态历程来看,该变动主要受城市产业与经济发展的影响。对中国主要特大城市实有人口规模变动的分析表明,特大城市的人口规模调控应因时因地而动,不能搞一刀切,而且人口调控政策重点应该从数量控制转向结构优化。特大城市转型升级面临着农民工供给短缺、大学毕业生相对过剩、老年和少儿非劳动力人口持续增长等人口新常态约束。在这种人口增长新常态背景下,特大城市应坚持市场化改革方向,促进政府制度创新和企业技术与管理创新是城市转型升级的根本动力。 相似文献

ABSTRACTWe examine the validity of five factor models for explaining the time-series and cross-sectional variations in stock returns in the Shanghai Stock Exchange. The factor models include four models proposed by previous literature. Moreover, we propose a four-factor model (comprising market, size, book-to-market, and sales-to-price factors) to explain variations of stock returns in the Shanghai Stock Exchange. The results show that the Shanghai stock market exhibits size, book-to-market, and sales-to-price effects. Both the adjusted coefficient of determination and regression model intercepts indicate that the proposed four-factor model explains variations of stock returns in the Shanghai Stock Exchange more effectively in comparison with other multifactor models. 相似文献

Nonparametric Evaluation of Economies of Scope in the Context of Technical Efficiency: The Case of Rice and Vegetable Farms in Korea 下载免费PDF全文
This paper provides a nonparametric evaluation of economies of scope in the context of technical efficiency allowing for non‐convexity, with an application to Korean rice and vegetable farms. Relying on non‐parametric‐free disposal hull and data envelopment analysis approaches and input–output data for rice and vegetable farms from the Korea Farm Household Economy Survey data collected in 2007, this article examines technical inefficiency and its decomposition under non‐convexity and convexity. Empirical measures of technical inefficiency and its decomposition results are provided, with a focus on a component of technical inefficiency associated with economies of scope (i.e. diversification benefits) under non‐convexity in production technology. The decomposition measures of technical inefficiency include pure technical inefficiency, size inefficiency and diversification inefficiency. The results provide empirical evidence supporting size‐dependent diversification strategies, where benefits of diversification are larger for small farms on average compared to those of large farms. 相似文献

customs are generally perceived as a time-consuming impediment to international trade. However, few studies have empirically examined the determinants and the impact of this type of government-imposed transaction costs. This paper analyses the role of firm size as a determinant of customs-related transaction costs, as well as the effect of firm size on the relationship between these costs and the international trade intensity of firms. The results of this study indicate that customs-related transaction costs repress international trade activities of firms, even at low levels of these costs. The paper identifies transaction-related economies of scale, simplified customs procedures and advanced information and communication technology as main determinants of customs-related transaction costs. It is shown that when these factors are taken into account, firm size has no effect on customs-related transaction costs. Policy implications are considered for firm strategy and public policy. 相似文献

Using data from a survey of 1,097 small and medium-sized non-listed Dutch firms we investigate the relation between growth of the firm and uncertainty. We focus on the impact of sales uncertainty on various types of investment. We find that sales uncertainty, measured by the conditional variance, has a mixed impact on various investment decisions. We include an analysis of the relevance of financial structure and firm size on the growth-uncertainty relation. 相似文献
