Formation of monopolies in a bipartite market

We study the formation of monopolies in a simplified economic model where two brands compete in the market, using an agent based model. Each agent represents a company that uses one of the two available brands and interacts with other companies. The brands continually improve their product in order to compete for market share. In the innovation process companies can decide to change to the other brand if the move is beneficial. There is a cost for the company if it decides to switch to the other brand, and another cost if it stays with its current brand but only upgrades to a new enhanced version of the product. Our simulations show that the system always reaches a state when all companies end using a single brand, which is equivalent to a monopoly. We study the time span needed to reach the single brand final state for different parameters of the model.     

Government,enterprise and resident: Roles of local agents in regulating and simulating built-up land use and change in a mining city

Various agents are involved in decision-making when built-up land is allocated and regulated, but the roles of these agents must be clarified. To aid this process, the agents in Wu’an (a mining city in China) were classified as government, enterprise and resident, and then their roles were analyzed to establish a decision-making mechanism. The model of physical site selection for enterprises and residents was quantitatively simulated, taking into account the qualitative constraints from government and enterprises. Based on these rules, eight scenarios under economic development-driven scenario (EDdS) series and the environmental conservation-driven scenario (ECdS) series were set up, and vertical and horizontal comparisons were implemented for analysis. Our study showed that the established models could be well fitted for simulation, and that economic development could stimulate the allocation of more built-up land. The most important achievement is that the proposed comparison can effectively distinguish among the roles of various agents, as well as quantify government and enterprise incentives.

不完全契约下经理和债权人之间的代理成本问题研究

自詹森和麦克林提出代理成本理论以来,理论界对代理成本理论的研究,全部集中在股东与经理之间的股权代理成本和股东与债权人之间的债权代理成本。而关于经理和债权人之间的代理成本问题,几乎是空白。本文通过对经理作为“合同收益者”与“剩余收益者”双重属性的分析,提出了关于经理和债权人之间代理成本问题研究的基本思路。

现代企业中委托代理关系存在的问题及对策

随着现代企业的进一步发展,企业规模不断扩大,由此产生了企业所有者管理才能与企业资产的不对称,所有者无法有效率的经营企业,继而导致了企业所有权与经营权的分离.本文主要研究两权分离后产生的委托代理关系中存在的问题,并有针对性的提出了解决方案.     

Micro-meso-macro

Building on the ontology of evolutionary realism recently proposed by Dopfer and Potts (forthcoming), we develop an analytical framework for evolutionary economics with a micro-meso-macro architecture. The motive for reconception is to make clear the highly complex and emergent nature of existence and change in economic evolution. For us, the central insight is that an economic system is a population of rules, a structure of rules, and a process of rules. The economic system is a rule-system contained in what we call the meso. From the evolutionary perspective, one cannot directly sum micro into macro. Instead, we conceive of an economic system as a set of meso units, where each meso consists of a rule and its population of actualizations. The proper analytical structure of evolutionary economics is in terms of micro-meso-macro. Micro refers to the individual carriers of rules and the systems they organize, and macro consists of the population structure of systems of meso. Micro structure is between the elements of the meso, and macro structure is between meso elements. The upshot is an ontologically coherent framework for analysis of economic evolution as change in the meso domain - in the form of what we call a meso trajectory - and a way of understanding the micro-processes and macro-consequences involved. We believe that the micro-meso-macro analytical framework can greatly enhance the focus, clarity, and, ultimately, power, of evolutionary economic theory.JEL Classification: B0, C0, D0, E0, O0, P0Kurt Dopfer, John Foster, Jason Potts: We acknowledge to those who have discussed these ideas with us at the Schumpeter Society Conference, Gainesville US 2002; ECG seminars, UQ Economics, Brisbane (also students of ECON7900); Doctoral seminars at University of St. Gallen 2002, 2003; Wartensee Workshops on Evolutionary Economics 2001, 2002, 2003; the MPI in Evolutionary Economics, Jena; SPRU, University of Sussex, Brighton; and the Brisbane Club Workshop, Manchester 2002.

So the usual disclaimer shall apply, although perhaps with unusual force. Special thanks also to G. Blind and K.

双重委托代理视角的内部控制

股权集中导致了小股东和控股股东间、控股股东与管理层间的双重委托代理问题的存在。作为内部控制思想渊源的委托代理关系的改变必然对内部控制理论的创新和发展提出要求，由中层会计核算系统和业务执行系统向高层决策系统渗透。与此相适应，内部控制需要从财务报告导向向价值创造导向转型。
