从人才市场的失灵谈人才引进政策的重要性

人才作为一种重要的稀缺资源，在高科技日新月异的今天越来越受到人们的关注。但是由于人才市场的滞后性、盲目性使得人才资源难以达到均衡配置。文章试图从人才市场的运行机制出发，从外部性、信息不对称等方面详细论述了人才市场的失灵问题，并提出要弥补市场失灵，政府制定相应的人才引进政策至关重要。     

有效市场假说的学说简史

有效市场假说领导创立四十周年之际，其能否成立是新古典金融学与行为金融学论战的焦点。本文回顾了自1900年以来有效市场假说的主要文献，研究了随机游走理论和有效市场理论产生和发展的学说史，同时评述了1970年以后有效市场理论的最新进展。本文厘清了有效市场假说与行为金融争论，提出套利限制是由制度性因素还是投资者心理因素是两者论战的实质，同时指明有效市场假说适用于一般均衡，而行为金融的更适用于局部均衡。     

Towards a European Academic Labour Market? Some Lessons Drawn from Empirical Studies on Academic Mobility

In Europe, academic mobility has a long tradition which began with the birth of the European universities in the middle ages. Recently, European policies were strongly oriented towards the promotion of student and academic mobility and the creation of research networks and projects within Europe. Nevertheless, academic labour markets in Europe remain highly national and many obstacles hinder the development of European careers and the europeanisation/internationalisation of academic recruitments. Two different perspectives will be developed in this paper. First we will document the strong divergences among the national recruitment and careers processes within Europe and the problems raised by this situation. Second, we will draw on two empirical studies we conducted on academic mobility, the first one, led in 1995 in France, Germany and the UK and the second this year in France. Both studies show that most post-docs conceived their foreign experience as a personal strategy and aimed at improving their chances for recruitment in their own country. Within Europe, foreign country careers still are an exception due to accidental opportunities.     

市场力对环境的威胁

市场需求以及由于急功近利而增加生产是驱使人们过分地开拓自然资源最终毁灭我们的环境两股力量.冬天在英国人的自选商场里绿色豆角的上市和肯尼亚境内已经岌岌可危的内瓦沙湖是很能说明问题的事例.     

What Can Institutional Research do to Help Colleges Meet the Workforce Needs of States and Nations?

Institutions of higher education are looked to by society as the training grounds and gatekeepers for college-trained workers. However, despite a long history of being viewed by many as unresponsive to labor force needs, the academy has not found ways of effectively meeting these demands, nor articulating why it is that they have difficulty doing so. This paper discusses how institutional researchers can help explain to campus administrators and others the role that institutions play in training individuals for the workplace, and why they cannot always quickly respond to and solve shortages of college-trained workers. The first section outlines what economic theory and research has to say regarding labor markets, how labor market shortages arise, and how students make decisions about which major to pursue. The last section describes problems institutional researchers face when using their skills with data to identify solutions to this problem. Using data from the state of New Hampshire, it will be shown that the data available to institutional decisionmakers can be out of date, inaccurate, and not particularly useful for designing policies that would enable an institution to respond to the labor needs of the economy.     

Structural marginalisation,othering and casual relief teacher subjectivities

Produced through market relations of neoliberal managerialism, teacher subjectivities are becoming progressively commodified. With the increasing casualisation of the teaching workforce, the well-being and status of casual relief teachers (CRTs) can be seen as an area of concern, at risk of ‘flexploitation’. More than just a convenient labour pool, CRTs operate on the margins of school communities, a space fraught with a range of issues. In many instances, CRTs experience less job satisfaction; less rapport with students and colleagues and less access to school information, professional development, resources and teaching materials. This article draws on a positioning theory to frame the discursive production of CRT selves within the neoliberal milieu. It offers a detailed analysis of collective biographies that explore narrative formations of casual teaching. Schooling discourse is replete with metaphorical language that frames teacher positioning, and a range of existing metaphors in CRT literature highlight their vulnerability in particular. Rather than offering an analysis that addresses casual teacher performance as a problem to be solved, this article proposes that the relationship between ‘structural marginalisation and the ‘othering’ that CRTs can experience is associated with the politics of market-related performativity.

School Admissions: Increasing Equity, Accountability and Transparency

This paper examines the impact of education reforms on school admissions policies and practices. It discusses the changes that are needed to improve the current system, especially in areas where the market is highly developed. It is concluded that the new legislation to be enacted by the current Labour Government should be beneficial, but that more far-reaching changes are needed for the admissions process to be equitable, transparent and accountable.

套期保值比率与套期保值的效绩--上海期铜合约的套期保值实证分析

通过对上交所期铜合约的套期保值功能进行实证分析,发现套期保值的效果与选择的策略和套期保值比率紧密相关。上交所期铜合约的最优套期保值比率低于1,在短期内,最优的套期保值比率仅为0．5。随着套期保值期限的增加,最优的套期保值比率也不断变大。在风险最小化的框架下比较了不同套期保值策略的效绩,结果表明虽然传统的套期保值在一定程度上可以起到转移风险的作用,但是基于最小方差的套期保值策略优于传统的策略。
