决算式住房反抵押贷款的产品设计与运行

快速和高度的人口老龄化给我国社会养老带来沉重的压力。以房养老是一种很好补充手段,但相关工作多年没有实质性进展。开发切合实际的金融产品品种,增强可操作性,才能突破尴尬局面。在充分权衡各方利益、考虑各种风险的基础上,提出了一种新的以房养老金融产品——决算式住房反抵押贷款,并对其年金计算、决算与结算等具体操作和运行进行了设计和探讨。     

浅析国际商事仲裁一裁终局制度的局限与完善

视一裁终局为国际商事仲裁的主要优点并将其绝对化,是我国学术界的普遍观念,而《仲裁法》也规定仲裁实行一裁终局的制度。然而,随着国际经济交往规模的扩大,一裁终局在国际商事仲裁实践中的缺陷逐一显现。本文通过分析,提出对"一裁终局"绝对存在性和绝对优越性的质疑,指出一裁终局的缺陷,进而提出在一裁终局制度上,我国仲裁法应当区分国内仲裁与国际商事仲裁,在国际商事仲裁中摈弃绝对的一裁终局制度。     

The Combination Strategy to Optimal Target Selection and Offer Segmentation in Direct Mail

The optimization of direct mail activities generally focuses separately on the issues of target selection and the selection of the strongest offer. In this paper we propose a combination strategy of the two practices through a response model which makes target selection specific to an offer. This combination strategy promises significantly higher profits than does the typical two-stage strategy.

Inductive research in last-mile delivery routing: Introducing the Re-Gifting heuristic

The last-mile problem presents a daunting challenge for many logistics service providers, especially some 7000 small, localized operations for whom the cost of complex software solutions is often prohibitive. As a result, last-mile dispatchers rely on simple heuristics to ensure adequate customer service at an acceptable cost. This research effort extends prior qualitative work by developing and testing a simple vehicle routing heuristic, based on behaviors observed in practice, that prioritizes customer service over cost against other simple vehicle routing heuristics across a variety of environments using simulation. The results support the inclusion of a customer service focus in vehicle routing and the addition of such heuristics to existing algorithm portfolios, specifically in urban areas with well-developed highway systems.     

How much can we trust China’s investment statistics?

Abstract

Building upon recent research into the underestimation of China’s official final consumption expenditure, this paper investigates the quality of China’s investment data. We strictly follow the official method to estimate the annual gross fixed capital formation (GFCF) expenditure from 2004 to 2012, and the resulting figures are significantly different from the official statistics. This implies that the ‘total investment in fixed assets’ data, which are the primary source for the estimation of GFCF, grossly exaggerate actual investments, and that the official GFCF figures are not, strictly speaking, independently estimated, as they are purported to be. We deduce that the official gross capital formation figure is more or less a residual item obtained by subtracting final consumption and net exports from the official GDP figure that is calculated based on the production-cum-income approach. As a result, the underestimation of China’s consumption expenditure automatically translates into overestimation of investment expenditure. We conclude that China’s official consumption and investment statistics cannot be trusted as the basis for policy discussions and academic research.

随着中国建筑企业管理体制改革的不断深入,招投标制度在中国得以推广应用。当前,我国的大部分项目的评标标底采用复合标底,投标企业要想在激烈的竞争中赢得中标,就必须采用科学的报价方法。从博弈论的角度出发,分析了投标报价的相关因素,建立了复合标底的博弈模型,通过一个实例演算该方法在实际中的应用,并证明此模型是有效可行的。     

What does the Chinese market need? An empirical study of the determinants of Chinese imports, 1996–2008

This study provides an in-depth analysis of the determinants of import demand in China through a multilevel approach. Using disaggregated data over 1996–2008 and a dynamic panel model, we find that the Chinese import market is predominantly characterized by quality competition. However, the nature of the competition varies across different industries. In line with theory, quality plays an important role in industries that are characterized by the potential for quality improvement and product differentiation, whereas price is key in industries in which quality and product differences are rather small. Moreover, private consumption expenditure is more influential than other categories of expenditures. Additionally, variables that can influence the relative price of import products, such as the exchange rate, tariffs and the domestic price index, also have an impact on import demand.
