互联网免费服务价值核算研究

近年来,越来越多的企业选择以低廉或免费的价格为居民提供互联网服务,但产出价值和消费行为却无法在GDP核算中体现。服务业产出被低估一直为学术界所讨论,在此背景下,互联网经济下创新的免费商业模式对传统核算理论的挑战成为本文研究切入点。本文在“互联网免费服务与顾客价值”的易货交易框架下对其价值核算展开研究,将互联网免费服务价值核算与数据资产核算联系在一起,使数据成为连接互联网免费服务与国民经济核算中生产、消费、收入核算的桥梁。文章最后通过模拟核算案例表现了互联网免费服务核算对不同账户的影响,建议对住户部门的生产、消费与收入各增加一笔虚拟处理,对企业的生产、收入及资产也各增加一笔虚拟处理,且这6笔虚拟价值相等。     

Approximation of the Bivariate Renewal Function

Recently, Kambo and his co-researchers (2012) proposed a method of approximation for evaluating the one-dimensional renewal function based on the first three moments. Their method is simple and elegant, which gives exact values for well-known distributions. In this article, we propose an analogous method for the evaluation of bivariate renewal function based on the first two moments of the variables and their joint moment. The proposed method yields exact results for certain widely used bivariate distributions like bivariate exponential distribution, bivariate Weibull distributions, and bivariate Pareto distributions. An illustrative example in the form of a two-dimensional warranty problem is considered and comparisons of our method are made with the results of other models.

世界各地的华侨华人经济联系建构了世界华商网络 ,并以此融入世界体系 ,形成了整个“中华经济圈” ;而包括粤港澳台闽桂琼在内的“华南经济圈”则构筑了“中华经济圈”的圆心 ,并维系其经济增长 (“圆周半径”)的动态平衡。“华南经济圈”由闽台经济区、珠江三角洲经济区、环北部湾沿岸经济区和环南中国海经济区所构成 ,它参与中国———东盟自由贸易区的优势主要在于地缘经济优势、特区经济优势和会展经济优势     

上海自贸试验区负面清单转化为全国负面清单的路径和措施

目前,在中国(上海)自贸试验区的各项实施制度中,"负面清单"制度是其中重要的一项,也将是未来自贸区可复制、可推广的一项关键制度。对此,可借鉴《美国双边投资协议2012年范本》,将上海自贸试验区负面清单转化为全国负面清单,向全国推广。

FTA 背景下新西兰对中国农产品出口增长分析

根据UN Comtrade数据库中贸易数据,采用恒定市场份额模型,对1997—2012年期间新西兰向中国农产品出口增长的影响因素进行了实证研究。结果表明,中国进口需求的增长是新西兰对中国农产品出口大幅增长的主要原因。在中国－新西兰自由贸易区建立后,增长效应对出口增长的带动作用明显减弱,商品效应和整体竞争效应贡献率有所回升,表明中国－新西兰自贸区建立后新西兰向中国出口的农产品结构有所优化,且在中国市场的整体竞争力提高;不同种类的农产品影响新西兰向中国出口农产品贸易额增长的因素有一定差异。     

上海自贸区外商投资“负面清单”的挑战与应对

上海自贸区外商投资“负面清单”管理模式的提出,有利于我国外商投资规则逐步与国际通行规则接轨,也将开启我国改革开放新的篇章。本文从宏观监管措施和产业开放两个层面,分析了“负面清单”面临的主要挑战和应对措施。初步结论为:宏观监管层面,政府应该逐步让位于市场,减少政府的审批事项,加快落实从事前监管向事中、事后监管的转变;另外,消除隐形壁垒,自贸区内给予外商企业真正的“准入前国民待遇”。产业开放层面,上海自贸区的产业开放应以金融业的开放先试先行;其次,联合天津和广东等新批准设立的自贸区,在各自成熟且有优势的行业破冰改革,为我国下一步的改革开放提供更为完备的可复制、可推广的经验。     

Old-Age Homes and Services

Summary

Although generational co-residence continues to be the dominant form of housing and care for Indian elders and only 1% live in old-age homes, the numbers and types of these homes are growing. This article describes a recent study of 48 old-age homes in different parts of India, approximately 12%-15% of all homes. They included the more traditional free homes for the aged poor who have no family to care for them and the more recent for-pay homes for the middle-class. A small number of day-care centers, also a new phenomenon, were investigated. Two- to three-hour structured interviews were conducted with managers, supervisors, and trustees, augmented by a checklist of environmental and neighborhood features. Most homes house small numbers of residents, have common spaces for dining, TV and prayer, have access to medical care and transportation, provide meals and some assistance with activities of daily living, and are open to all castes. All are run by non-governmental organizations (NGOs), only one-third with any government assistance. Free homes tend to be bigger and older, serve non-aged clients, have less privacy and emphasize occupational therapy and income-generating activities, and are more like board-and-care homes. For-pay homes have more privacy and western-style amenities, focus on local community outreach and provide fewer meals. The gradual increase of all old-age homes has given rise to debates about their appropriate roles in Indian society and about their quality. Government grants to NGOs for homes and day-care centers (often considered more appropriate support for elders) are limited. With the National Policy on Older Persons looking to NGOs and village councils to be the primary sources of non-familial aged care, several ways to build their capacity are suggested.     

Trade, education, and innovation: Prospects for the U.S. economy

This paper examines international trade issues as vital indicators of the economic prospects of the United States and other developed economies. In particular, it challenges misuses of the doctrine of mutual gains from trade and instead argues that comparative advantage does not guarantee increases in benefits to both trading partners—especially when one partner seeks to distort the market mechanism in its favor. In the face of such mercantilist or protectionist practices, efforts to advance innovation, without retaining manufacturing jobs, will not ensure continued prosperity, as the number of jobs entailed in the invention process is small compared with the number of jobs associated with manufacturing an innovative product for mass consumption. These matters call for the urgent rethinking of trade policy by the United States and other developed nations, if they are to balance their imports and exports and ensure continued economic growth.
