A two-stage stratified Warner’s randomized response model using optimal allocation

This paper applies Kim and Wardes (2004) stratified Warners randomized response model to Mangat and Singhs (1990) two-stage randomized response model. The proposed stratified randomized response model has an optimal allocation and a large gain in precision. Hence, the estimator based on the proposed method is more efficient than Kim and Wardes (2004) and Mangat and Singhs (1990) estimators under the conditions presented in both the case of completely truthful reporting and that of not completely truthful reporting by the respondents.     

对ESOP激励有效性的质疑

本文提出在ESOP实施过程中存在着员工持股股份占企业总股份的比例较低;员工个人持股比例很低的现状,并针对这种现状,质疑“有效员工激励”是否能够实现。本文将结合模型,主要从ESOP是否能增加员工有形动力和是否能增加员工无形动力两个方面来具体阐述自己的观点。     

The political economy of industrialisation

This paper analyses how incentives under different sets of political institutions map into policies that promote industrialisation. I set out an endogenous growth model with non-overlapping generations, where agents are heterogeneous with respect to wealth, skills and political power. The skills of the political elite play a crucial role for industrialisation to occur. It is shown that a flat wealth distribution and a skilled political elite enhance development the most in elitist regimes, while democracies perform as well as elitist regimes in terms of industrialisation. The theoretical results regarding elitist regimes are in line with evidence on the Industrial Revolution.     

路径依赖的作用:家庭联产承包责任制的建立与演进

人地比例、耕作技术、土地产权制度之间的互动循环导致了中国历史时期土地产权制度演进中路径依赖的形成。中国目前人口与资源（土地）之间的紧张关系就是历史时期土地产权制度演进的结果，这一约束条件决定了中国土地产权制度只能是朝着更加周密细致地保证农民土地长期使用权与收益权的方向演进。从公社一级到三级所有、大队为基础，到三级所有、队为基础，再到家庭联产承包责任制的建立，直至承包期限由短期变为长期，由15年变为30年。这一步步的演进都是朝着保证农民土地长期使用权与收益权的方向回归，显现出制度变迁过程中路径依赖的作用。由于历史时期土地产权制度演进的影响，家庭联产承包责任制完善的方向应该是土地国家终级所有的前提下，强化农民现有土地长期使用权，并通过法律手段保证土地使用权的转让。     

特细砂配制高流动性泵送C55预应力混凝土应用

本文通过试验分析特细砂粒径,不同材质的特细砂的基本物理材性,采用现代混凝土配合比设计理念,研究了特细砂混凝土配合比的设计原则。通过分析砂率含量、用水量、高效外加剂对特细砂高性能混凝土在工作性和力学性能上的影响,确定砂率含量的范围;通过对特细河砂和天然特细山砂混凝土性能的对比试验,结果表明细砂完全可以替代天然中粗砂配制高性能高强度、高流动性泵送混凝土。     

Optimal rebalance rules for the constant proportion portfolio insurance strategy – Evidence from China

The constant proportion portfolio insurance (CPPI) strategy is one of the most popular asset allocation strategies employed by guaranteed-return financial products investors. Rebalance disciplines play an important role in determining the CPPI performance in practice. This paper examines whether the selection of rebalance rules affects CPPI strategy performance in the context of Chinese equity markets and, if so, in what pattern, and whether an optimal parameter of rebalance exists. We find that, (1) the three alternative rebalance disciplines – time discipline, market move discipline and lag discipline – are indifferent in affecting the performance of CPPI strategy; (2) in terms of optimal parameters of each rebalance rule, the optimal rebalancing period for the time discipline is 3 trading days, the optimal trading threshold of the market move discipline 4%, and the optimal lag factor of the lag discipline 6%. These optimal parameters are not influenced by the length of investment.     

A true simulation study of three estimators at equal protection of respondents in randomized response sampling

In this study, three different estimators for estimating the proportion of a sensitive attribute in survey sampling are compared at equal protection of the respondents. The three estimators considered are due to Odumade and Singh (2009, Comm. Statist. Theory Methods) , Singh and Sedory (2011, Sociological Methods and Research) and a new estimator obtained by minimizing a chi‐squared distance. A SAS Macro is developed to compare these three estimators using a simulation study at equal protection of the respondents. A set of data from a real face‐to‐face interview was collected using two decks of cards and has been analyzed. The results are discussed.     

我国省区三次产业就业结构与劳均资本存量关系分析

在经济发展过程中,就业结构变化和劳均资本存量上升是经济发展质量提高的根本要求。本文搜集并利用近二十年相关数据,计算了我国各省区三次产业就业比例与劳均资本存量。分析发现,各省区第一产业就业比例急剧下降、劳均资本存量迅速增长,劳均资本存量与就业结构变化存在显著的因果关系,资本存量上升促进了就业结构优化;省区之间就业结构、劳均资本存量差距很大。因此,政府应采取均衡投资战略,避免资本过度集中;发达省区应进一步优化资源配置,提高资本产出效率;中西部省区则应加强资本积累、因地制宜发展产业,促进第一产业劳动力就近转移。     

Intellectual Property Securitization and Growth Capital in Retail Franchising

A retail franchisor needs growth capital so that the brand continues to grow and franchisor–franchisee relations remain strong. However, access to corporate liquidity to fund such franchise growth options is not unlimited. A method of raising finance particularly suited to retail franchisors is intellectual property (IP) securitization that allows companies to account for intangible assets such as intellectual property, royalty and brands and realize their full value. In recent years, a number of large restaurant franchisors have securitized their brands to raise funds, including Dunkin Brands and Domino's Pizza (Domino's). We use property rights approach to show that IP securitization provides mechanisms that explicitly define ownership of intangible assets within the securitization structure and thus enables a company to raise funds against these assets. Using a case study example of a retail franchise IP securitization transaction, we also provide evidence that these mechanisms are not overly restrictive and can be used more widely to help fund retail franchise growth and expansion.     

机构投资者持股的旅游上市公司特征分析

旅游业已成为我国新的经济增长点,旅游上市公司是我国证券投资市场的重要板块。以2006-2008年旅游上市公司为样本,将旅游上市公司分成酒店类、景点类和综合类,研究机构投资者持股比例与公司特征之间的关系。实证研究表明,景点类旅游上市公司在股东获利能力、发展能力、抗风险能力等方面均优于酒店类和综合类旅游上市公司。而且,更深入的研究发现,总资产报酬率、净资产收益率与景点类旅游上市公司机构持股比例呈现出显著的正相关关系。
