基于价格与信用的产业集群竞争优势博弈分析

产业集群是指某一特定区域内相互联系的企业与机构之间在地理上的集中,是介于市场和科层组织之间的一种新的空间经济组织形式.产业集群内企业之间的博弈可以导致某种企业均能接受、具有一定市场稳定性、与一般市场价格相比具有一定竞争优势的市场均衡价格.同时在产业集群内部,由于违背信任的代价高昂,企业有足够的动力维持相互之间的信任与合作关系,比邻而居的企业之间由于频繁的交往和经常性的合作,产生了面对面的观察与学习的便利性,可产生较强的联合行动效应.企业通过合作达成资源、信息上的共享,促进由于创新带来技术上的升级,从而使集群内企业互惠互利、共同发展.     

Not all gamblers are created equal: gambling preferences depend on individual personality traits

Previous studies have presented evidence revealing that the dispositional personalities of consumers, or the traits associated with their gambling behaviors and risk preferences, differ across various gambling types. Those studies leave open the question of whether and how personality differences affect domain-specific gambling preferences. Using latent class analysis (LCA), we explored the latent classes of risk preference for different gambling types and the effects of personality traits on these classes. A total of 732 Macau residents completed a questionnaire assessing 13 gambling types and personality traits. Preferences for gambling shown by the participants varied between three latent classes of games: chance gambling, entertainment gambling, and technical gambling. Moreover, not all personality traits consistently predicted preferences for these gambling classes. For instance, aggression-hostility positively predicted a general preference for both chance gambling and technical gambling, but impulsive sensation-seeking positively predicted only a preference for chance gambling. However, neuroticism-anxiety traits showed no such predictive effect for any of the three gambling classes. This study suggests that personality patterns emerge for overall and specific gambling types and underscores the value of LCA to help resolve the longstanding debate over whether gambling is domain specific.

论人身保险单的质押

人身保险单质押是权利质押.目前实践中主要以人身保险单的现金价值权为出质标的,从法律和质权的安全性考量,法律上应当明确人身保险单所表彰的投保人的现金价值权和被保险人、受益人的受益权均可以出质,投保人、被保险人、受益人均可作为出质人,而有关风险由质权人来考量和控制.人身保险单质权的设立和公示为确保交易便捷和安全,应当以登记...     

An empirical study of selection and estimation of statistical growth models

In this paper the linear and the exponential statistical growth models are compared to enable the empirical researcher choose the appropriate model for purposes of estimating growth rates. It is concluded that the exponential model outperforms the linear model.     

The Impact of Antitakeover Amendments on Corporate Financial Performance

Previous event studies that examine the impact of antitakeover amendments on firm value provide mixed results. Some studies support the management entrenchment hypothesis, while others support the shareholder interest hypothesis. In this study, a longitudinal approach is used to examine the impact of antitakeover amendments on several financial attributes of the firm including: operating and net income to total assets, operating and overhead expenses to sales, research and development to total sales, capital expenditures to sales, and debt relative to total assets. It is concluded that antitakeover amendments are not deleterious in terms of their impact on various fundamental firm performance measures.     

THE SEASONALITY IN CONVERTIBLE BOND MARKETS: A STOCK EFFECT OR BOND EFFECT?

There is a strong January effect in convertible bond returns that has been partially attributed to seasonality in the underlying stock. January returns for convertible bonds are positively influenced by the degree to which the bond reflects the underlying equity, which suggests that the anomaly in one asset market may carry over to its derivative asset market. Significant evidence presented here indicates that the January effect also is attributable to unique tax-loss selling in the convertible bond market. A peripheral contribution of this study is that, similar to findings in the stock market, the risk-return trade-off appears to hold only in January for convertible bonds.     

A disequilibrium model of real wages,employment and unemployment for the U.S.A. during 1930–1965

The well known Lucas-Rapping (1969, 1970) U.S. Labour market model has been estimated with a simple disequilibrium estimation method. Neither the wage rate nor the employment level are found to adjust to clear the labour market within the unit time period. The elasticity of labour supply in the short run is found to be high which is consistent with the recent theories of real business cycle. Adjustment in employment towards equilibrium is faster than the adjustment in the wages. The rate of unemployment is satisfactorily explained by the excess supply rate without the need for the lagged unemployment rate. Thus our unemployment equation is superior to the Lucas-Rapping equation based on the equilibrium framework.I am grateful Professors J. W. Nevile, V. K.
