Government as a discriminating monopolist in the financial market: the case of China

We show that the many unusual features of China’s financial markets are consistent with a government choosing regulations to maximize a standard type of social welfare function. Under certain conditions, these regulations are equivalent to imposing explicit taxes on business and interest income, yet should be much easier to enforce. The observed implicit tax rates are broadly in line with those observed in other countries. The theory also forecasts, however, that China will face increasing incentives over time to shift to explicit taxes.     

注册会计师行业监管的若干问题研究

针对我国对舞弊的会计师事务所处罚力度明显不够的事实，监管机构应加大处罚力度，在确定合理处罚的基础上选择适当的监管力度，政府监管力度按成本效益原则确定监管费用的最优投入，决定监管机构的规模和大小，并完善相关的机构建设。     

Incomplete regulation, market competition and collusion

Regulators often do not regulate all firms competing in a given sector. Due to product substitutability, unregulated competitors have incentives to bribe regulated firms to have them overstate their costs and produce less, thereby softening competition. The best collusion-proof contract entails distortions both for inefficient and efficient regulated firms (distortion ‘at the top’). But a contract inducing active collusion may do better by allowing the regulator to ‘team up’ with the regulated firm to indirectly tax its competitor. The best such contract is characterized. It is such that the unregulated firm pays the regulated one to have it truthfully reveals its inefficiency. We finally compare those contracts.     

Some properties of the length of the shortest half

经营杠杆与经营杠杆度的论述

本文运用杠杆原理,研究分析了经营中存在的经营杠杆及其杠杆度,推导出经营杠杆度的计算公式,阐明了经营杠杆在P-S图中的位置及其确定方法。得出以下几个结论:①经营杠杆是实际经营中客观存在的;②经营杠杆度DOL与安全边际系数MRS互为倒数关系,两者都对企业的经营状况起警示作用;③经营杠杆度DOL对销售收入S的函数为单调减函数;④企业应力求通过减小DOL来增加息税前利润EBIT。     

论中国特色社会主义经济学的核心范畴

确立中国特色社会主义经济学的逻辑起点，必须突出它的特殊性，而不能照搬以往的经济学。迄今，所有的经济学由于其任务和宗旨不同大体可分四种类型、四个逻辑起点。中国特色社会主义经济学根据它的任务和宗旨，需要在科学社会主义实践逻辑的基础上，进行科学抽象，分析其矛盾特殊性的三个表现及中国的个性，揭示以社会主义本质为核。范畴和逻辑起点的理论规定性，进而全面展开，创立新的架构。     

Sustainable resource use,economic development,and public regulation

The role of production technology for sustainable economic growth and resource management in the multispecies renewable resources industries is a neglected issue, particularly in complex tropical ecosystems. Given the still rudimentary understanding of biological interactions among species, even in most temperate ecosystems, the importance of under-standing the technological and economic interactions is heightened for sustainable economic growth and public regulation. This paper evaluates these interactions for the multiproduct gill net fisheries of Peninsular Malaysia. Standard price and quantity controls may have little promise. Gear regulations, a policy of constant escapement, and managing the entire mix of species as a single stock for economic rather than biomass yield appear the most promising management tools given the limited regulatory options.     

试论调控个人收入分配的财税政策选择

根据实际情况，我国政府调控个人收入分配，在财政政策方面，应加快完善社会保障制度，加大转移支付力度，缩小地区经济差距，加大扶贫投入的力度；在税收政策方面，应进一步完善个人所得税制度，适时开征遗产税与赠与税，加强特别消费税的作用，建立个人财产税制，适时开征社会保障税。     

总量均衡区间与宏观调控应确立的若干新原则

现代市场经济条件下,供给方调整其生产规模所需的成本可称为调节成本。由于存在调节成本,传统分析中的“总量均衡中心点”两侧便分别存在着“低位临界点”与“高位临界点”,这两点界定了一个特殊的“总量均衡区间”。“总量均衡区间”的出现对宏观调控将产生诸多重要影响,使之面临一系列新问题、新挑战。为有效应对这种新情况,在宏观调控实践中有必要相应地确立“近似均衡原则”、“适度超前原则”、“临界点原则”、“供给方原则”。
