Demand disruption and coordination of supply chain via effort and revenue sharing

This article explores the equilibrium behaviour of a basic supplier–retailer distribution channel under demand disruption via effort and revenue sharing contract. This differs from the traditional supply chain coordination model. Firstly, demand is simultaneously affected by retail price and nonprice marketing effort from manufacturers and retailers. Secondly, when the demand is disrupted, this article considers disruptions in the market scale and price sensitivity coefficient. Thirdly, the supply chain coordination model is proposed via effort and revenue sharing contract. In this way, the manufacturer reduces the wholesale price as an incentive for the retailer to share revenue. Finally, the total supply chain profit is greater with contract than no contract. This also constitutes another incentive for the players to follow the effort and revenue sharing contract.     

Optimal policy with credibility concerns

This paper considers a reputation model of optimal taxation in which the public is unsure about the government type. A long-lived government can be trustworthy (meaning that it commits to its announced tax rate) or opportunistic (meaning that it retains the ability to change its tax rate after announcing it). Unlike in most prior studies, the committed strategy in this model is optimally chosen by the trustworthy type. We show that this change has significant consequences for the equilibrium dynamics. The optimal committed strategy is found to vary with the time preferences of the two government types, the initial reputation of the government, and the elasticity of household production. This formulation explains differences in policy responses across governments in the face of similar credibility problems.     

金融支持我国实体经济发展的有效性分析

实体经济稳企回转是国民经济良性发展的基础.在国内经济转型发展的攻坚时期,大量金融资本投向虚拟经济领域,发展中不平衡、不协调问题一直存在,金融支持实体经济发展的有效性引发质疑.本文从金融支持实体经济发展的现状出发,指出金融支持实体经济的针对性、有效性不足的原因,强调统筹金融市场建设、优化金融信贷政策、引导金融资源投向、加大金融产品创新、规范民间金融发展、建立成效考核机制等多个方面是确保资金投向实体经济,提升金融支持实体经济有效性的重要举措.

国防经济的地区性和外部性——中国的国防经济如何与经济建设协调发展

在当今国际关系复杂多变的背景下,即使各国间的博弈逐渐变得缓和,也改变不了国防经济在各国至关重要的作用。而对于世界上发展程度不同的国家,国防经济的发展程度也会不同,且不同的国防经济发展也对经济发展带来了不同的外部影响。本文是在综合了时代特征的情况下,探讨不同国家的不同程度的国防经济建设所揭示的地区性和所带来的外部性影响。     

Governing business process offshoring: Properties,processes, and preferred modes

This article examines an important yet understudied issue—the governance mode for business process offshoring (BPO). By applying transaction cost economics and organizational control perspective in the global BPO context, we suggest that BPO's governance mode (foreign captive, joint venture, and independent vendor) is determined by task features, such as knowledge specialization, information security, and process codifiability, and by needed process integration, horizontally between departments and units within the provider and vertically between the provider and its global client and its local subcontractor. Findings from our analysis of 308 global BPO units in India and China confirm our hypotheses.     

Corruption and FDI: Does the Use of Distinct Proxies for Corruption Matter?

Abstract

The relationship between FDI and corruption/institutional quality in host countries has been widely analyzed. However, the use of distinct samples and indicators for corruption tends to hinder the interpretation and outcomes of econometric assessments. The aims of this paper are to assess the extent to which the use of distinct proxies for corruption provides diverse evidence regarding the relationship between corruption and FDI, and to assess whether controlling for other indicators of institutional quality reinforces the effect of corruption indicators on FDI inflows. In order to accomplish these goals, we estimate a set of multivariate logistic models using 96 countries over the period 2000 to 2010. The results evidence that using distinct proxies for corruption variables, as well as controlling for other types of the countries’ institutional quality, generate distinct outcomes. In isolation, a country’s transparency and its citizens’ corruption perceptions fail to impact on FDI whereas a bribe-free environment is conducive to FDI inflows. When we control for the human, social and economic development of the countries, the impact of a transparent and bribe-free context on FDI attraction is enhanced. Overall, it is clear that in order to become a large recipient of FDI a country has to guarantee a transparent and bribe-free environment, characterized by low income taxes, high literacy rates and generalized economic freedom (own labor and property control by citizens).     

“80后”员工组织支持感对离职倾向的影响研究

采用问卷调查法以及验证性因素分析、偏相关分析和分层多元回归分析等统计方法,探讨"80后"员工的组织支持感对其离职倾向的影响作用进行分析,并在影响作用方面与工作满意度方面进行了比较。结果表明,"80后"员工的组织支持感呈多维结构,可分为工具性支持感、情感性支持感、利益性支持感、价值性支持感和发展性支持感五个维度。"80后"员工的组织支持感总体对其离职倾向有显著的负向影响作用,并且单独地、利益性和发展性支持感对离职倾向具有显著的负向影响作用。"80后"员工的组织支持感比工作满意度对其离职倾向有更强的影响作用。     

基于层次分析法的地方财政收入风险评估指标体系优化及实证分析——以江苏省的数据为例

地方财政收入风险管控的研究已成为一个世界性的课题。本文以刘谊等人关于地方财政收入风险研究为基础,全面考虑新经济环境背景及地方债务收入因素的变化,对地方财政收入风险评估指标体系进行了系统优化分析,并采用层次分析法设计其指标权重。最后以江苏省13个地市的相关数据进行检验,发现优化后的指标体系的权重一致性更高,风险评估结果更贴合实际,并据此提出一些相关风险监控的建议。     

我国沪深股市同配性和网络导航现象研究——基于复杂网络理论

分别按照地区、行业、市值三种分类标准对我国沪深市场股票进行分类,以股票为网络节点,研究了三种分类标准下的股票同配性,进而研究了行业分类标准下的网络导航现象。结果表明:上海市场和深圳主板市场在阈值较高、按行业分类时表现出较为明显的同配性;沪深股市在阈值较低时表现出一定的异配性,而当阈值达到一定程度时表示出较强的同配性;网络导航现象体现了股市中异类股票间的相互影响作用;中国股市存在较多的网络导航现象;在较长时期内造成该现象的主要原因是分类标准不准确、股票涉及共同的炒作概念、具有共同的股权投资对象、新股上市日期相近等,短期内的原因还包括消息面或事件性的驱动因素。
