教育收益率对中国收入差距的影响——基于分位数回归模型的分析

采用中国家庭追踪调查数据（CFPS2014），运用分位数回归模型探讨教育收益率对中国收入差距的影响。研究结果表明：（1）随着收入分位点的提高，中国的教育收益率逐渐下降，教育收益率有助于缩小中国不同群体的收入差距；（2）配偶的受教育年限对低收入个体的影响更大；（3）城镇的教育收益率高于农村，教育收益率的城乡效应将加剧城乡收入差距；（4）东部地区的教育收益率高于中西部地区，教育收益率的区域效应将加剧区域收入差距。总的来讲，教育收益率虽然会缩小不同群体的收入差距，但会扩大城乡和区域收入差距。     

沪深股市月份效应和月初效应的实证研究

文章利用上证综合指数和深圳成分指数的数据，采用基本统计分析、参数方法和非参数方法（Kol—mogorov—Smimov检验、Kruskal-Wallis检验、Mann—Whitney检验）对沪深股市的月份效应和月初效应进行了实证分析。结果表明，沪深股票市场均不存在收益率的月份效应，而存在显著的月初效应，在样本期内，两市从前一交易月的最后一个交易日到本交易月的第六个交易日期问的日平均收益率显著为正，并且远远高于剩余交易日的日平均收益率。     

我国沪深股指收益率波动性的实证研究——基于ARCH模型族

本文基于我国1997年7月3日至2011年7月2日的数据,利用ARCH模型族,对我国沪深股指日收益率的波动性进行了实证研究。结果表明:沪深股市收益率的分布非正态,具有尖峰厚尾特征;它们的波动具有集聚性、持久性和杠杆效应;沪深股市中高收益伴随高风险。总体来看,沪深股市在收益率波动特征上的差异不大。     

中国权证上市日和到期日效应的实证研究

文章选取2007年6月30日之前到期的18只权证为研究对象，以权证所对应的正股价格日收益率、交易量日增长率、日超常收益率比和日超常交易量比等为考察指标，对我国权证的上市日效应和到期日效应进行了实证分析。得出的结论是：在5％显著性水平上，以一天为时间间隔，我国权证的上市日效应和到期日效应均不显著。     

GARCH族模型在中国股市中的应用——上证综合指数波动性研究

以1997年1月1日至2009年5月6日的上证综合指数的日度收盘数据为样本,运用带学生-t分布的GARCH族模型对其进行实证分析,检验了在这一段时间内我国股票市场的波动情况以及波动的杠杆效应,分析结果表明了上证指数对数收益率服从非正态分布,具有尖峰厚尾和明显的ARCH效应,并且股票的收益率具有明显的风险溢价和杠杆效应。     

深成指数的混沌吸引子分形维研究及预测

近几年来，用混沌理论来分析金融市场的变化规律，已经逐渐成为金融市场非线性研究的热点。本文以1991年4月3日至2000年12月29日的深成指数的日收盘价（共计2392个数据）为样本，利用Wolf算法计算出深成指数对数收益率序列的最大Lyapunov指数，用G-P算法求出深成指数对数收益率序列的关联维数，从而证实我国证券市场的运行具有混沌特征。     

收益率平价在货币危机预测中的应用

在本文中，我们首次提出了用收益率差作为领先指标来预测由危机的发生。本文从理论上证明了过去的实际收益率中包含预期收益率信息，从而从理论上解决了用过去实际的收益率差来预测货币危机的可行性问题。对19个国家25年（1975－2000）月度数据的拟合效果表明，经汇率调整后对美国股市收益差有着较好的预测结果，同时我们的结果也表明收益率预测指标对2001年7月爆发的阿根廷货币危机有较好的样本外测效果。     

基于GARCH族模型的中国股市通信板块收益率波动分析

文章运用GARCH族模型分析中国沪深股市通信板块指数日收益率的波动特性,发现信息通信板块收益率是一个平稳过程,其波动具有＂聚集＂和＂非对称效应＂的特点。而GARCH（2,1）模型比GARCH（1,1）模型更好地消除了收益率序列的异方差,其中非对称模型TARCH（2,1）模型的拟合效果最好;GARCH-M模型和非对称的CARCH（1,1）模型都不适用于描述其收益率的波动特征。     

ARIMA模型在债券收益率中的应用

通过对债券即期收益率的分析，可以更加精确地知道债券收益率的变化情况。本文采用统计学家Box和Jenlins提出的ARIMA模型对我国债券收益率数据进行分析，得出ARIMA模型不但适合非平稳的时间序列，而且适合分析债券收益率，表明ARMA（1，1，1膜型的效果是比较好的。     

中国股票市场月交替效应及其影响因素研究

本文选取从2000年第一个交易日至2017年5月10日约18年的收益率数据为样本,探讨我国股票市场的月交替效应及其影响因素.研究发现,我国股票市场存在显著的月交替效应,且这种效应不只存在于大盘股或小盘股,也不仅局限于高价股或低价股;月交替效应并不由交替日的高风险所导致;月交替效应并不由年度交替或季度交替引起;月交替效应不仅仅存在于沪市,深市和港市也同样存在.     

Development in Information and Communications Technology (ICT) Statistics at the Australian Bureau of Statistics

This paper outlines the ICT statistical developments that the ABS has undertaken over recent years. These developments have been on both the supply side (ICT industry) and the demand side (use of IT by sector). The content of ABS ICT surveys has changed significantly over the last few years and are expected to develop further in line with industry changes and emerging policy needs.
Recent developments in household collections have been the inclusion of IT use questions in the 2001 Census of Population and Housing and in various ABS social surveys such as Children's Participation in Culture and Leisure Activities. Annual business IT use surveys are now conducted and include topics such as Internet commerce and IT security. Biennial ICT industry surveys are conducted to provide data on ICT production, imports and exports, ICT industry employment, performance and structure information. An Internet activity survey is run every six months and provides regional Internet access details and infrastructure details on Internet service providers.
A major development for 2002–03 will be the compilation of an ICT satellite account. ABS intends to produce an ICT Information Development Plan to guide its future statistical development work in the ICT field.     

Value at Risk in the Suburbs: Eminent Domain and the Geographical Politics of the US Foreclosure Crisis

Several US counties and local governments have recently considered a novel solution to the foreclosure crisis. They plan to use eminent domain to compel the owners of mortgage debt—and specifically of private‐label mortgage‐backed securities—to sell the debt to the government at a price reflecting the loan's market value. The government would then restructure the debt and resell it to new investors. The plans are striking because—in contrast to both development‐driven eminent domain and the federal subprime bank bailout—they would force investors to assume asset devaluation and increased long‐term risk. Notably, the plans have emerged as an instance of financialization‐focused politics in suburbs and suburban cities of color, specifically majority‐black and ‐Latino/a suburbs. Local support for the plans, we argue, is rooted in the long‐term disinvestment of these ‘suburbs of exception', which became targets of subprime lending and eventually sites where the ‘financial exception' has been localized. But these demographic shifts, fragmentation and fiscal pressures have at the same time created a suburban political terrain in which the plans have gained their strongest political support.     

Towards a Theory of Serendipity: A Systematic Review and Conceptualization

Serendipity – the notion of making surprising and valuable discoveries – plays a major role in the success of individuals and organizations alike. Previous research has established the importance of serendipity and identified important individual- and organizational-level antecedents. However, the literature has been dispersed and the boundaries of the concept have been blurry, leading to a lack of conceptual clarity and structure, and thus limiting validity and managerial actionability. Based on a systematic literature review, I synthesize existing management-related research on serendipity and explicate the emergence and composition of serendipity in the organizational context. I first identify three necessary conditions that differentiate serendipity from related concepts such as luck or targeted innovation: agency, surprise, and value. Then, I draw from the literature on sensemaking, event-based theorizing, and quantum-based approaches to management to conceptualize the process of cultivating serendipity in the organizational context as a process of enabling potentiality and materialization, and develop a multi-level theory of (cultivating) serendipity. This conceptualization contributes to our collective understanding of how, why, and when (i.e., under what conditions) organizations can leverage the value in the unexpected, which opens up fruitful avenues for further research.     

Accountability of NGOs in Bangladesh A critical overview

NGOs in Bangladesh have been recognized as effective change agents in the socio-economic arena throughout the world. Their contributions in micro credit, non-formal education and primary health care are widely known. NGOs play a significant role in society. NGO accountability, as a result, has become a critical issue. NGO accountability in Bangladesh has been examined here in relation to patrons, clients and themselves. Of the three relationships only accountability to patrons is in a near satisfactory state. Accountability to clients is handicapped by lack of opportunities of beneficiaries to participate meaningfully in NGO policy making. Accountability to themselves is adversely affected due to the adherence to a strictly hierarchical system and the influence of founding and charismatic NGO leaders.     

Towards an Asian model of human resource management? A comparative analysis of China,Japan and South Korea

There has been much discussion regarding the possible decline and weakening of national systems of human resource management (HRM). Yet, culture and institutions are often cited as the major stumbling blocks to this outcome. Such constraints may dissipate in the analysis, particularly if ‘regional clusters’ are considered where geographic and cultural closeness and ‘openness’ to similar economic pressures exist. In such cases, it might be postulated that convergence in HRM will occur. We argue that China, Japan and South Korea represent such a cluster. This article examines these countries, to see if a degree of convergence is taking place and if it is towards an identifiable ‘Asian’ model of HRM. A model of change is presented that distinguishes between levels of occurrence and acceptance. Details of the development and practice of HRM in each country are then set out. The article ends with a discussion and implications section and a brief conclusion.     

Ansätze und Ergebnisse anglo-amerikanischer M&A-Forschung

Based on a review of established U.S. management journals (1995–2003), six schools of thought are identified within the Anglo-American M&;A research: “Capital Market”, “Principal/Agent”, “Industrial Organization”, “Organizational Behavior”, “Human Resources” and “Strategic Management”. The literature review shows that the definition of M&;A success, the methods applied, and insights from empirical research differ according to the respective school of thought. Empirical studies focus on the resource combinations of merger partners, the specific circumstances of merger negotiations, and on integration management as antecedents of merger performance. Unfortunately, empirical findings have not yet provided reliable explanations for M&;A success. Based on the current state of Anglo-American M&;A research, the authors discuss implications for business practice, identify research gaps, and propose areas for future research.     

Introduction of New Technology with a Sound Transition of the Input-Output Structure

We examine the general equilibrium repercussions associated with the introduction of new technologies, using the generalized Leontief system that allows technological substitutions. We show that an untested introduction of cost-increasing technologies in any industry may result in creating a non-productive technological structure that does not satisfy the Hawkins-Simon condition, following the autonomous dynamic adjustment process with structural transitions in the economic system. Therefore, we propose a practicable control scheme of introducing cost-increasing technologies that strictly avoids the creation of non-productive structures in all periods of structural transition, using the available information on the ex ante technological structure.     

The Creation of the Office for National Statistics

A new Office for National Statistics was created in the United Kingdom in 1996 following a series of developments designed to strengthen the relevance and integrity of statistics. This paper describes these fundamental changes and sets out a blueprint for future progress. It also sets current developments in the United Kingdom in an historical and international context.     

What helps? Women engineers' accounts of staying on

We have considerable understanding of the obstacles that women engineers encounter and the reasons that they leave the field, but we know less about what enables them to remain. Adopting an interpretivist approach, this article examines how a group of British women engineers in two FTSE 100 companies account for “staying on” in their male‐dominated work settings. We delineate four specific forms of help that facilitate women's retention in the field. We argue that exposure to help leads to women developing a habitus that enables them to continue working in engineering. To conclude, we draw on our findings to outline HR practices that will facilitate supportive relationships in the workplace and pave the way towards developing more positive organisational climates.
