Game Theory, Information Economics And Accounting Information Distortion Study

With the economic development, the function of accounting information(AI) is more important, but, embarrassedly, the quality of AI is the very reverse with economic development, more seriously, distorted AI causes much inconvincible problem. AI is originally of help to stakeholders'decision-making, now AI induces them to be wrong. Genuine information(GI) provision is in favor of market credit system's establishment and perfection, but distorted accounting information(DAI) floods in the market, ceaselessly pile out high-quality AI, engender AI lemon market, badly cumber to realize the socialist market economy. GI can be used to evaluate corporation and industry in favor of the government to institute policy of economic development, but, DAI can not. Distorted information makes state-owned assets loss, and even worse, it influences the government to command the economic status.GI indicates the true condition of the corporation, including the scale, input-output level and core competition, DAI makes corporation to disguise in order to take up the market, so that, ill competition engenders, the market order is destroyed, market mechanism can not be perfected, worse still, it severely influences the collocation and the societal development. By this token,it has practical significance to study the countermeasure to AID and to furthest ensure the authenticity of AI. This dissertation is focused on the solution to accounting information distortion(AID).There are four chapters in this dissertation. Chapter 1 mainly introduces current study and their deficiency, then expounds the grand meaning of this dissertation. Chapter 2 firstly defines the AI and illuminates the disquisitive objection, on this base, divide AID into two types:regulation distortion(RD) and rule-violating distortion(RVD) with reference of WU Lian-sheng. This part will make the disquisitive objection more precisely. Chapter 3 uses cost-benefit method to analyze the causes of RD and RVD. From micro-level, the cause of RD is faultiness of accounting standards(AS) and accounting institution, macroscopically dues to the inconsistent between accounting rules and accounting order. As for RVD, principal-agent relationship is the objective basis, the incompatibility of utility function and asymmetric information between principle and agent are the essential conditions, and the bigger net income of violating the rules, the lack of accounting honest-credit system and insufficient enforcement and supervision are the direct motivations. This part aims to set up a general logic analytical frame for AID study, its significance is to establish a foundation for the latter analyses which uses Game theory and information economics theory.Chapter 4 studies the countermeasures to AID from each level in use of Game theory and information economics theory, so this part is the keystone and difficulty. This part is composed by two parts, the first one mainly uses game theory to discuss RD. In order to remove the deviation between the accounting order and accounting rule, it must to find a way to establish accounting order then to compare with accounting rule and detects the deviation. The thought is to ascertain and discuss the stakeholders firstly, then to analyze the game model through game evolution. On the precondition of equilibrium, modify the game strategy and Game-matrix to find out the condition which the accounting order needs. In the whole analyses and research, it integrate the think of game theory, meanwhile, it combines the countermeasures. The next to discuss constitution and enforcement of accounting standards issues from the government and the enterprise level respectively. This part makes the standards constitutor and executor as objection, uses Game theory and the cost-benefit analytical method to put forward a way to solve RD through a geometrical model. The geometrical model directly indicates the existence and probability of pareto optimal in the course of standards formation. In the end of this part, the dissertation briefly explains two question of standards enforcement: accounting policy choice and earning management. The second part mainly uses information economics theory to analyze the profound reasons of RVD, and provides a two-dimensional framework for solving RVD. Firstly, make the accounting information provider(AIP) and accounting information users(AIU) as the study object. From AIP aspect, enlightened by The problem of social cost of Coase, this dissertation discusses the negative externality which is taken by distorted AI and the influence to the whole society, then elaborates the countermeasures to hold the behavior of AIP from two aspects: accounting information quantitative of accounting information quality and negative externality transfer. As for accounting information quality, it makes a mathematical model on the foundation of abundant reference through a series assumption to weigh the accounting information quality. This method is reasonable and persuasion. As for externality transfer, this dissertation find the solution through mathematical model too, meanwhile, uses many geometrical graphics to explain the course. At last, bring forward the bail of the lowest accounting information quality to restrain the behavior of accounting information provider's false accounting information provision behavior. Accordingly, from AIU aspect, this dissertation analyzes the ill affection, which is taken by free-riding behavior of AIU, to the whole accounting information market and social credit system, enlightened by The logic of collective action of Olson, it tries to discuss the individual into collectivity, bring forward the critical point mechanism of supply. Convincingly, this part makes use of mathematical model to elaborate the critical point mechanism of supply. In the end, the solution is that through critical point mechanism of supply, it can effectively curb AIU's free-riding behavior and AIU's and unassailably to improve accounting information quality.
