中国城市要素利用质量水平测算与研究:基于要素市场扭曲视角

基于2000-2016年期间中国30个地区260个地级及以上城市的平衡面板数据,将要素市场扭曲划分为资本要素市场扭曲和劳动要素市场扭曲两个部分,采用超越对数生产函数测算中国城市资本要素市场扭曲和劳动力要素市场扭曲水平并进行研究,在此基础上进一步分析城市生产要素扭曲水平与城市规模之间的关系。研究结果发现:2000-2016年期间,中国城市总体的资本要素市场和劳动力要素市场均处于较为严重的扭曲状态,两种要素市场上均出现了负向扭曲,且资本要素市场扭曲比劳动力要素市场扭曲程度更为严重,即城市资本—劳动相对扭曲指数显著大于1;中国260个城市的资本要素市场均出现负向扭曲,劳动力要素市场出现正向扭曲和负向扭曲的城市分别占据全部样本城市的38.5%和61.5%;中国城市要素市场扭曲水平与城市规模均呈现倒“U”型关系,当城市人口规模分别超过475.80万人和379.18万人时,城市人口规模对资本要素市场扭曲和劳动力要素市场扭曲的影响由正向变为负向。     

内部评级法中违约概率与违约损失率的测度

内部评级法(IRB)是巴塞尔新资本协议的核心内容之一,违约概率(PD)和违约损失率(LGD)又分别是内部评级法的两个核心变量,所以对违约概率和违约损失率的测度就成了内部评级法的关键。文章就PD和LGD的测度方法进行了详细分析和论述,对LGD的计量模型进行了简述,并指出我国银行实施IRB法要完成的工作。     

以资本经营战略推动我国电信企业国际化

现代电信企业由于其经济属性和技术特点,随着国内电信市场的日趋饱和以及别国电信市场控制的放松,电信企业便会产生强烈的国际扩张愿望,力图通过摊薄后更低的边际成本来获取更大的市场份额和投资回报.而资本经营是国外电信企业走向国际化的重要手段.我国电信企业目前在这方面还存在着一些问题,主要有企业战略管理较弱、资本经营的意识不强、人才匮乏、缺少有效的激励约束机制等.

Investing in a robotic milking system: a Monte Carlo simulation analysis

This paper uses Monte Carlo simulation methods to estimate the breakeven value for a robotic milking system (RMS) on a dairy farm in the United States. The breakeven value indicates the maximum amount that could be paid for the robots given the costs of alternative milking equipment and other important factors (e.g., milk yields, prices, length of useful life of technologies). The analysis simulates several scenarios under three herd sizes, 60, 120, and 180 cows. The base-case results indicate that the mean breakeven values are $192,056, $374,538, and $553,671 for each of the three progressively larger herd sizes. These must be compared to the per-unit RMS cost (about $125,000 to $150,000) and the cost of any construction or installation of other equipment that accompanies the RMS. Sensitivity analysis shows that each additional dollar spent on milking labor in the parlor increases the breakeven value by $4.10 to $4.30. Each dollar increase in parlor costs increases the breakeven value by $0.45 to $0.56. Also, each additional kilogram of initial milk production (under a 2x system in the parlor) decreases the breakeven by $9.91 to $10.64. Finally, each additional year of useful life for the RMS increases the per-unit breakeven by about $16,000 while increasing the life of the parlor by 1 yr decreases the breakeven value by between $5,000 and $6,000.

Existence of perfect equilibria in a class of multigenerational stochastic games of capital accumulation

In this paper we introduce a model of multigenerational stochastic games of capital accumulation where each generation consists of m different players. The main objective is to prove the existence of a perfect stationary equilibrium in an infinite horizon game. A suitable change in the terminology used in this paper provides (in the case of perfect altruism between generations) a new Nash equilibrium theorem for standard stochastic games with uncountable state space.     

Social Media Use for News and Individuals' Social Capital,Civic Engagement and Political Participation

Recently, scholars tested how digital media use for informational purposes similarly contributes to foster democratic processes and the creation of social capital. Nevertheless, in the context of today's socially‐networked‐society and the rise of social media applications (i.e., Facebook) new perspectives need to be considered. Based on U.S. national data, results show that after controlling for demographic variables, traditional media use offline and online, political constructs (knowledge and efficacy), and frequency and size of political discussion networks, seeking information via social network sites is a positive and significant predictor of people's social capital and civic and political participatory behaviors, online and offline.
