大户与散户在证券市场的博弈

通过对Laffon的模型进行了改进，将散户的效用函数改成了常系数绝对风险厌恶的负指数形式。Laffon的结论为：当θ1,θ2相距不远时，大户与散户都偏好混同均衡。而改进后的模型却找到了θ1,θ2的距离在一个具体的范围内，大户与散户才都偏好混同均衡。     

论我国农民集体土地所有权

我国农村集体土地所有权法律地位不明的一个根本原因是缺少对农村集体土地的物权制度设计,传统上对农村集体土地的公有制设计是从政治经济的意义出发的。在坚持集体土地公有制的前提下,认可集体土地所有权是民法上的私权利大有裨益,由此也有必要赋予每一个“农民集体”以法人地位,并精心设计该法人的治理结构,从而成为确保我国社会主义公有制得以实现的一种良好的方式。     

基于大数据的计算机网络信息安全防护措施

大数据是基于云计算技术开发的一种集成技术,可以通过分析、计算和处理大量数据信息来实现这些数据的价值。然而,随着大数据时代的到来,现有的计算机网络面临着新的挑战,特别是网络安全问题逐渐浮现,计算机网络带来的安全隐患导致用户个人的隐私受到了威胁,所以有必要加强网络信息安全工作的部署,以尽早遏制这些安全风险,并确保计算机网络的安全运行。

普惠型医疗保险发展:实践困境与优化方向

近年来,普惠型医疗保险成为多层次医疗保障体系发展的一大热点。文章首先介绍了中国普惠型医疗保险的发展现状及主要特点,其次通过对国内部分保险公司线上及线下调研,发现当前普惠型医疗保险发展面临配套法律法规有待健全、市场认可度普遍偏低、可持续经营能力不强、保险效果低水平重复、相关主体联动不足等困境。进一步分析美国、英国、德国、新加坡相关经验,提出具体的优化路径:以优化顶层设计为立足点,提高保险规制水平;以强化市场环境建设为切入点,提升市场认可度;以优化运行模式为突破点,激发保险生命力;以设计差异化产品为关键点,强化保险增补性;以建立联通机制为动力点,提高相关主体协同度。     

Does the social security fund help non-financial enterprises to transform from the virtual to the real?

At its 19th National Congress, the Communist Party of China vowed to “strengthen the financial sector’s ability to serve the real economy.” However, many studies provide evidence of the opposite trend, a problematic “transition from the real to the virtual,” among Chinese enterprises. Meanwhile, the investment efficiency of China’s Social Security Fund (SSF), a public fund, attracts much attention. In this context, we use A-share listed companies in China from 2009 to 2018 to study the relationship between holding by the SSF and enterprise financialization. We find that SSF holding significantly inhibits financialization and that this effect is non-linear. Mechanism analysis indicates that SSF holding suppresses enterprises’ financialization mainly by improving their governance. Moreover, SSF holding more strongly inhibits small-scale (vs. large-scale), state-owned (vs. non-state-owned), and non-eastern (vs. eastern) enterprises in China. Furthermore, SSF holding can alleviate corporate value impairment caused by financialization. The conclusions enrich theoretical research and provide empirical evidence that may help regulatory authorities to guide investment by enterprises and prevent financial risks.     

Evaluating Projects and Assessing Sustainable Development in Imperfect Economies

We are interested in three related questions:(1) How should accounting prices be estimated?(2) How should we evaluate policy change in animperfect economy? (3) How can we check whetherintergenerational well-being will be sustainedalong a projected economic programme? We do notpresume that the economy is convex, nor do weassume that the government optimizes on behalfof its citizens. We show that the same set ofaccounting prices should be used both forpolicy evaluation and for assessing whether ornot intergenerational welfare along a giveneconomic path will be sustained. We also showthat a comprehensive measure of wealth,computed in terms of the accounting prices, canbe used as an index for problems (2) and (3)above. The remainder of the paper is concernedwith rules for estimating the accounting pricesof several specific environmental naturalresources, transacted in a few well knowneconomic institutions.     

Teams, Firms and the Evolution of Profit Seeking Behavior

Even as advances in information theory over the last quarter century have cast increasing doubt on the proposition that firms successfully maximize profits, the objective of profit maximization continues to be an axiomatic feature of the neoclassical theory of the firm. This paper attempts to improve our understanding firms by treating the objective function as an open question. Specifically, an ontogenetic thought experiment is undertaken to address the question of what differentiates production teams from firms by asking why team members would sell their control rights to a principal, thereby transforming the team into a firm. What results is an account of the emergence of the objective of profit seeking. Profit seeking emerges endogenously as a more fit alternative than the objective of value maximization, which is less capable of coping with uncertainty through purposive adaptation.     

Trade and Renewable Resources in a Second Best World: An Overview

We provide an overview and introduction to the emerging field of trade and renewable resources, and discuss the potential impact of trade liberalization on welfare and resource conservation. A key factor determining the effect of trade reform is the institutional context or property rights regime, and our survey is organized such that it loosely follows the development of new insights with respect to institutions in this literature. This implies a transition from the benevolent planners model to the polar opposite benchmark of open access in the 1990s. Currently the pendulum is swinging back towards management and regulation, but institutions are treated as endogenous. We discuss and compare various key models in some detail and search for common ground between protagonists and antagonists of free trade. Paper based on Keynote address by Erwin Bulte, 12th Annual Conference of the European Association of Environmental and Resource Economists, Bilbao (Spain), June 28–30, 2003.     

我国金融监管法律制度的反思与改造

作为部门行政法律制度建构的一部分,金融监管法律制度在国家经济生活中具有十分重要的作用。目前我国的金融监管法律制度还存在着较大的缺陷,突出表现在金融监管立法不完备,法律、法规混杂、重复、遗漏及空白之处甚多,对监管主体的规定存在缺失,央行的独立监管地位弱化,关于金融监管的手段、方法的规定不完善,以致造成执法缺乏力度。在国外资金大量涉入国内、国际金融及监管规则约束国内的金融机构之前,必须完备我国的金融监管法律制度。
