Incumbency advantage and its value

Markets with network effects are typically concentrated. The aim of this paper is to discuss some recent work on “incumbency advantage.” That is, the fact that firms already installed generate higher profits than entrants even if the latter offer identical or even better terms (in terms of price and quality) to consumers. In particular, we review recently known sources of the advantage and potential mitigating factors and point to a number of open issues.     

法律院校参与法律援助的价值及利用

服务社会是高等学校的应有功能与职责。于高等学校法律院系而言,参与法律援助应该是践行社会责任的最基本和最重要的形式。随着人权事业的日趋进步和发展,法律院系参与法律援助面临更大的机遇和挑战。正确认识高校参与法律援助的资源优势、价值,正视并有效解决存在的问题,对于法律合格人才的培养、对于法律援助本身均具有超越性的意义。     

PRICING DERIVATIVES ON MULTISCALE DIFFUSIONS: AN EIGENFUNCTION EXPANSION APPROACH

Using tools from spectral analysis, singular and regular perturbation theory, we develop a systematic method for analytically computing the approximate price of a large class of derivative‐assets. The payoff of the derivative‐assets may be path‐dependent. In addition, the process underlying the derivatives may exhibit killing (i.e., jump to default) as well as combined local/nonlocal stochastic volatility. The nonlocal component of volatility may be multiscale, in the sense that it may be driven by one fast‐varying and one slow‐varying factor. The flexibility of our modeling framework is contrasted by the simplicity of our method. We reduce the derivative pricing problem to that of solving a single eigenvalue equation. Once the eigenvalue equation is solved, the approximate price of a derivative can be calculated formulaically. To illustrate our method, we calculate the approximate price of three derivative‐assets: a vanilla option on a defaultable stock, a path‐dependent option on a nondefaultable stock, and a bond in a short‐rate model.

中国金融危机法构建的探讨

本次震撼全球的美国金融危机给世人敲响了金融危机不定时爆发的警钟。全球化背景下金融危机的传染性更强、金融风险更大。中国相对脆弱的金融体系需要探索如何防范金融系统性风险,如何健全金融监管体系的制度与法制建设。随着人民币国际化过程深入,制定并颁布《金融危机法》能克服目前金融监管纵向监管体系缺陷,对提高我国金融监管机构应对金融危机能力、稳定金融市场与保增长具有重要意义。     

The legal theory of finance and the financial instability hypothesis: Convergences and possible integration

This article presents the legal theory of finance (LTF) and compares it with the financial instability hypothesis (FIH), identifying points of convergence and divergence. The study aims to contribute to the literature by connecting these theories and provides the following main conclusions. First, the LTF incorporates aspects of the FIH, as the theories share several key elements, particularly the presence of fundamental uncertainty, the constraint of liquidity, and the necessity for governments to act as lenders of last resort. Second, the liquidity concept used in the LTF can be better comprehended with the use of Keynesian and post Keynesian literature on the topic. Third, the LTF aims to advance and update certain aspects of Minsky’s theory, particularly with regard to the globalization of markets, power relations, and the interdependencies of the political economy of finance. The study concludes that the theories are more complementary than divergent and future studies should create an analytical framework that integrates the theories’ most insightful aspects.     

知识产权壁垒研究综述

在国际贸易往来中,知识产权作为贸易保护主义的一种工具被发达国家越来越频繁地使用,形成了一种新型的贸易壁垒即知识产权壁垒,随着贸易摩擦的频率与次数逐渐增多,其对贸易国家尤其是发展中国家构成了较大的威胁与障碍。立足于我国实际,通过结合国内外学者最新研究成果对知识产权壁垒研究进行梳理与总结并得出启示,提出我国相关产业与企业应客观看待并积极应对知识产权壁垒,不断提高自主创新能力与国际竞争力。     

第三方支付相关基础法律问题探讨

第三方支付不是单纯的货币转移支付,而是与商业交易密切相关。互联网支付是典型的"担保支付",第三方为付款人的货币支付和收款人的货物交付进行了担保,有效保证了交易合同的全面履行,付款人支付的货币资金具有反担保保证金性质;预付卡支付和银行卡收单支付都是委托代理支付,预付卡支付第三方收到付款人的货币资金属于保管行为。
