提升总体劳动收入份额过程中的结构优化问题研究——基于产业与部门的视角

基于收入法GDP和资金流量表核算的劳动收入份额数据,本文在探讨劳动收入份额构成、波动性并进行结构分解的基础上,研究了总体劳动收入份额稳步提升中的结构优化问题。在提升总体劳动收入份额过程中,在保持产业(部门)结构相对稳定时要重视产业(部门)内部劳动收入份额的结构优化,在维持产业(部门)劳动收入份额相对稳定时要重视不同产业(部门)增加值比重提高过程中的产业(部门)结构优化;还要重视产业(部门)内部效应和产业(部门)结构效应的协同对稳步提升总体劳动收入份额的综合效应。在优化结构时稳定维持第一产业(企业部门)劳动收入份额和努力增加第三产业(住户部门)增加值占国民经济的比重对提升总体劳动收入份额至关重要。     

Entry into platform‐based markets

This paper examines the relative importance of platform quality, indirect network effects, and consumer expectations on the success of entrants in platform‐based markets. We develop a theoretical model and find that an entrant's success depends on the strength of indirect network effects and on the consumers' discount factor for future applications. We then illustrate the model's applicability by examining Xbox's entry into the video game industry. We find that Xbox had a small quality advantage over the incumbent, PlayStation 2, and the strength of indirect network effects and the consumers' discount factor, while statistically significant, fall in the region where PlayStation 2's position is unsustainable.

The welfare effects of mobile termination rate regulation in asymmetric oligopolies: The case of Spain

This paper examines the effects of mobile termination rate regulation in asymmetric oligopolies. It extends existing models of asymmetric duopoly and symmetric oligopoly where consumer expectations about market shares are passive. First, demand and product differentiation parameters are calibrated using detailed data from the Spanish market from 2010. Next, equilibrium outcomes and welfare effects under alternative scenarios of future termination rates are predicted. Lowering termination rates typically lowers profits of all networks and improves consumer and total surplus.

能源价格波动对粮食生产成本的动态影响研究

能源价格波动会对中国粮食生产成本造成冲击,而且不同类型能源价格波动的动态冲击效果存在差异。运用向量自回归模型和脉冲响应函数研究发现,煤炭价格对粮食生产成本的影响十分显著,石油价格对粮食生产成本具有潜在影响。农户会调整生产要素投入以应对能源价格对粮食生产成本的冲击,但由此也给粮食生产带来负面影响。因此,应推广科学的粮食生产方式,减少对能源的依赖,并完善能源价格挂钩型农资的调控政策以及优化农资补贴方式。     

Volatility spillovers and connectedness among credit default swap sector indexes

This article studies volatility spill-over effects and market connectedness using daily data of credit default swap spreads for U.S. companies over a period from 2007 to 2012. We quantify volatility spillovers by means of an unconditional analysis performed using the entire sample, and a conditional analysis which estimates the model using a rolling window. As our database contains the global financial crisis (GFC), we are able to determine how volatility spillovers spread in the economy during the recent market turmoil. Our unconditional results confirm that the Financials sector was a main contributor to the overall market volatility along with the Consumer Goods, Consumer Services and Basic Materials sectors. The conditional analysis clearly identifies that the Financials was the major feeding sector of volatility spill-over effects, and that the market volatility was successively driven by Technology and Basic Materials over a rather short period of time, followed by Consumer Goods and Consumer Services over a prolonged period of time. Our results illustrate indirect linkages between the sectors that conveyed shocks during the GFC.     

福利保障体制改革的消费效应研究

九十年代中国进行了以住房教育医疗养老为主要内容的福利保障体制改革,这种改革曾对我国消费产生了巨大的影响,这种影响目前是否还存在以及多大程度上存在着?这对判断我国当前宏观经济状况及走势具有重要意义.本文的分析说明,福利保障体制改革内在的动态效应减少了表面看起来对消费的可能的冲击,而保险的替代效应的存在使福利保障改革对消费的抑制效应至少在我国中等以上收入群体中大大缩小,但对低收入群体的影响依然很大.     

Technology spillover effects within Spanish communities

The article uses panel data for the period 1990–2010 to estimate technology spillover effects on 17 Spanish communities. Accounting for nonstationarity and cointegration, we use the dynamic OLS estimator to estimate the impact of domestic and non-domestic R&;D capital stock on labour productivity of Spanish communities, taking into account trade-, migration- and foreign direct investment (FDI)-related technology diffusion channels. We find significant trade-related spillover effects within Spanish communities and from EU countries. On average, an increase in the non-domestic R&;D stock of 1% increases their labour productivity between 0.02% and 0.12% if related to bilateral trade pattern. Moreover, migration within Spanish communities has a negative impact ranging between ?0.07% and ?0.16% on labour productivity as the impact of inward migration is dominated by outward migration. There is no robust impact from FDI inflows of OECD countries in general or EU countries in particular. Finally, the domestic R&;D stock, physical capital and human capital are shown to be significant drivers for labour productivity in Spain no matter if non-domestic (local or foreign) spillover effects are trade-, migration- or FDI-related.     

关键描述变量在市场细分中的中介作用研究

描述变量研究中存在的问题以及营销实践中的困惑要求研究者构建一种新的市场细分范式.文章根据有关学者提出的模型进一步在描述变量中提炼出关键描述变量的概念,认为主要由客观需要、目标价值观、信号价值观和消费资源构成的关键描述变量对人口统计因素等基本描述变量与行为变量之间的关系具有中介作用,以私家车为例的实证结果也基本支持了这一假设.文章建议营销者可尝试采用新的市场细分范式,即对消费者的关键描述变量进行直接测量和细分,然后一方面用来解释和预测消费行为,为怎样营销服务;另一方面用来寻找相应的人口统计特征,进而为哪里营销服务.
