信用对服务业增长的影响：理论探讨与经验研究

本文首先通过超边际分析对信用促进服务业发展的机制进行形式化证明,然后利用包括32个OECD经济体与90个非OECD经济体在内的共122个国家或地区1997-2011年的数据,运用静态面板固定效应模型和动态面板FD-GMM估计方法,并按照全部样本、OECD样本与非OECD样本的类型进行经验研究,最后审查了研究结论在中国的适用性。结果发现：静态面板模型下,信用水平与服务业增长率显著正相关,这一结论对全部样本、OECD样本、非OECD样本都成立;动态面板模型下,信用对服务业增长的促进作用在全部样本与非OECD样本中仍显著,但是在OECD样本中不显著;信用推动服务业增长的边际生产力随着信用存量的增加而递减;信用是推动我国服务业增长的重要因素,且其边际生产力较高。     

银行视角下农村土地承包经营权抵押融资探析

随着2014年中央一号文件的出台,农村土地承包经营权抵押融资问题再次引起广泛的关注。当前农村土地承包经营权抵押融资面临着法律禁止和政策突破的矛盾。在这个背景下,推行土地承包经营权抵押融资亦面临着一些不容忽视的困难,如抵押融资渠道不足、银行业金融机构面临高风险、相关配套机制不完善等。这就需要通过完善相关配套机制、完善以风险管理为核心的土地承包经营权抵押贷款银行管理体制、探索土地承包经营权抵押担保新模式等措施突破困境。     

Truthful germs are contagious: A local-to-global characterization of truthfulness

We study the question of which social choice functions from an abstract type space to a set of outcomes are truthful, i.e., implementable by truthful mechanisms, when utilities are quasi-linear. For convex domains, our main theorem characterizes truthful social choice functions as those satisfying two properties: local weak monotonicity and vortex-freeness. The first of these constrains the function values at any two sufficiently proximal points, while the second asserts that its line integrals around sufficiently small triangular loops must vanish.The characterization implies a local-to-global principle that allows one to deduce truthfulness of a function from its behavior on arbitrarily small neighborhoods of each point. Other consequences include a simple alternate derivation of the Saks–Yu Theorem that weak monotonicity characterizes truthfulness of functions having a convex domain and finite range, and a sufficient condition for constructing truthful functions by “stitching together” truthful subfunctions on different subsets of the domain.     

流量垄断的理论框架与规制路径

数据要素的流动反映了市场供需信号的传递,流量竞争的本质是交易机会的争夺。数字平台的核心功能是流通,其以提高信息撮合效率为抓手进行注意力竞争,这决定了撮合对象的范围可以无限广阔,关注生产的相关市场界定则会因撮合市场跨多个生产领域而难以界定“基准产品”,因此流量代表的注意力相关市场难以测定。基于“联系一结构”视角,本文认为数字生态中存在中心、次中心和外围这三种角色,并从“平台-数据-算法”（PDA范式）三个维度进一步固化中心独占流量入口的格局,形成了中心对次中心,次中心对外围成本依次转移的“中心一外围”依附剥削体系。针对以控制交易机会分配为目的的流量垄断,本文提出三条规制路径：第一,在反垄断分析框架中突出相关时间市场;第二,拓展反垄断法中交易相对人的内涵,实现结构性平台对联系性平台跨生态开放为目标的互联互通;第三,导入开放平台原则,对结构性平台划定必需设施,构建数字平台的寡头竞争规则。     

Decline of Controlled Foreign Company Rules and Rise of Intellectual Property Boxes: How the European Court of Justice Affects Tax Competition and Economic Distortions in Europe

The European Court of Justice (ECJ) has become an influential player in the field of direct taxation in the European Union (EU) in the past 20 years. However, it is unclear whether or not the ECJ's decisions and the corresponding reactions by the member states actually contribute to tax neutrality in economic terms and, therefore, to the achievement of the internal market. In 2006, the ECJ limited the applicability of specific tax rules in the EU that are intended to prohibit the excessive use of low‐tax countries by multinationals. Our counterfactual analysis shows that the court's restriction of so‐called controlled foreign company rules and the related second‐round reactions by some member states – i.e. the introduction of low‐tax regimes for income from acquired intellectual properties (IP boxes for acquired IP) – cast doubt on the seemingly positive effects the ECJ has on reducing tax distortions. In addition, we demonstrate that the restricted applicability of IP boxes as endorsed by the OECD and the European Commission would strengthen tax neutrality in Europe.

The Value of a Utilitarian Curriculum: The Case of Technological Education

The position taken in this paper is that narrow conceptions of human development and the purposes of schooling have tended to displace rather than situate subjects like technology in the curriculum. Arguments which support this position, however, are only possible when the paradigm through which schooling is operationalized, is inverted. Viewing classic school subjects as abstractions which perpetuate narrow conceptions of pedagogy is a contentious position to take. But taking it and understanding how a utilitarian curriculum spawns real human development and learning gives a whole new perspective to curriculum theory and practice.
