Is globalization a road to duopoly?

In global markets, the market shares of the two or three biggest firms sum up more than 90 percent and firms do marketing efforts. However, the classical neo-walrasiano theoretical framework only is able to justify these stylized facts with particular firms’ cost structures, being one reason the presumption that there are no information costs. Towards the rationalization of those stylized facts, I study the evolution of the market structure in a model of price advertising with a variable that controls the degree of openness of regional markets. The main result of the model is that in equilibrium the structure of a global market is the duopoly.

Have labour practices and human rights disclosures enhanced corporate accountability? The case of the GRI framework

This paper critically evaluates Transnational Corporations’ (TNCs) claimed adherence to the Global Reporting Initiative (GRI)’s ‘labour’ and ‘human rights’ reporting guidelines and examines how successful the GRI has been in enhancing comparability and transparency. We found limited evidence of TNCs discharging their accountability to their workforce and, rather, we found evidence to suggest that disclosure was motivated more by enhancing their legitimacy. TNCs failed to adhere to the guidelines, which meant that material information items were often missing, rendering comparability of information meaningless. Instead, TNCs reported large volumes of generic/anecdotal information without acknowledging the impediments they faced in practice.     

再谈环境保护税设置——基于两类竞争制造企业环保技术创新策略的演化博弈

利用演化博弈模型分析处在竞争的两类制造企业(在位企业和进入企业)的环保技术创新策略问题,考量以环境保护税为主体的环保规制如何科学设置才能更好地促进制造业企业的环保创新.研究发现:创新效应和市场需求均影响企业创新策略演化的均衡结果,并在两阶段博弈分析的基础上,得出市场需求和创新效应共同作用下两类制造企业的生产策略选择方案.因此,环境保护税的改革与实施应注意掌握好时点,税率的设置应充分考虑不同行业环保创新效应和产品市场需求,进行区别化的、动态的税率设置,并加大其他税种对环境保护税的支持.     

供应链金融利益主体的多阶段博弈研究

现代经济中,金融在资源配置方面发挥的作用明显不足,出现严重的资源浪费和供需错配现象,加剧了中小企业面临的融资难问题.本文从供应链金融的内涵切入,建立以利益相关者为主体的融资量化模型,利用多阶段博弈理论对企业不同模式下的成本收益进行检验,结果表明:供应链金融在实现上、下游各利益相关者个体的最优化的同时,也可有效促使供应链整体的利益最大化、实现高效运作和价值增值,全面实现链上企业间的资源共享、互利共赢.     

Optimizing the credit term decisions in supply chain finance

We study a credit term determination problem in the context of a supplier-buyer supply chain. The supplier's credit term decision is simultaneously made with its production and inventory decisions, and most importantly, it is impacted by the buyer's order quantity. We present a new game-theoretic framework to model this problem, which captures the interaction between the supplier's credit term decision and the buyer's order decision in a multi-period setting. An exact method based on nonlinear programming is implemented to obtain the optimal solutions. We apply our methodologies on a real world case. The computational results show that our approach significantly outperforms the heuristics with fixed credit terms, and either a short or a long credit term can be sub-optimal for the supplier in profitability. Our work offers the first data-driven model and solution approach that assists purchasing and supply managers to make optimal dynamic credit term decision in conjunction with production, ordering and inventory decisions in a game-theoretic setting.     

论企业创新与规范化管理的关系——从智猪博弈的视角

企业发展稳定的程度,直接决定于企业基础管理水平的高低。企业基础管理水平的高低,又直接决定于企业规范化管理的程度。企业规范化管理就是通过建立、健全、完善、优化一套公开透明、上下认同、系统完整、行之有效的游戏规则来实施管理。可是,很多企业领导人总担心企业规范化管理会约束员工的创新探索,降低企业的创新力。由智猪博弈故事可知,一个企业有无创新力,与企业管理是否是通过游戏规则的建立、健全来实现无关,而仅仅与游戏规则的内容相关。任何企业组织,要保证创新力,规范化管理都是前提。只有规范化管理,才能建立、健全能激发员工创新热情、积聚员工创新能力的游戏规则。     

会计政策选择研究

会计政策选择是会计主体一种有目的的、在会计政策中进行挑选的行为,它与会计信息失真和盈余管理之间有一定的联系.由于会计准则的不完全性和会计信息市场的不完全竞争,会计政策选择行为必然长期存在.企业管理当局在选择会计政策时,是从自己的利益出发的,与会计信息的质量要求并不一致,因而,必须通过行为主体、会计准则、监管机制等方面的制度完善以达到提高会计信息质量的目的.     

公共选择视角:论组织制度的宽放效应

在组织中,因利益、文化、能力等差异形成的不同利益群体,为博弈各自最大利益所实现的群体共同利益点是所有利益中最小共同点,它是组织为实现一定政治、经济利益目标所确定的最低约束标准和必须实施的强制性要求,是组织中最大范围内的最小认同.当组织为实现更高目标而将制度向某些群体行为倾斜时,不同利益需要群体将与组织倾斜制度不能在最大范围内实现最小认同,使得制度或成本极高或效率极低或极不公平,导致制度出现宽放效应.     

多寡头不确定条件下的矿山企业期权博弈基本价值研究

期权博弈方法把实物期权和博弈论结合起来,在不确定性条件和竞争环境下,为企业提供项目的投资估价和决策,以实现投资项目价值的最大化。竞争环境下的矿山企业博弈参与方不再局限于对称双寡头,而是考虑了序贯均衡阶段的多寡头矿山企业,在进行项目投资决策时,可假设投资初期成本各不相同,建立多寡头矿山企业期权博弈基本价值的价值函数和最佳投资时机进行研究。
