Estimates of the demand for medical care under different functional forms

We estimate price and income elasticities from a linear, log-linear, and the almost ideal demand model (with and without an adjustment for selectivity bias) in an effort to show that special attention should be paid to the underlying assumptions of consumer behaviour when estimating a medical care demand model. The literature on medical care utilization is extended by incorporating two major components of spending as separate demands in a system of medical care spending. We find that estimates of elasticities vary depending on the functional form of the estimating equation, thus questioning the usefulness for policy purposes of single estimates of elasticities.     

关于支持小微企业转型发展的思考

目前,小微企业在经济社会发展中扮演了越来越重要的角色,但由于小微企业存在着先天性不足,抗冲击抗风险的能力较低,国际国内经济环境一旦出现变化,很容易陷入困境。近些年来,小微企业的困难越来越凸显出来。为了帮助小微企业缓解困难,国家出台了一系列政策措施支持小微企业转型发展,金融部门也制定了多项措施办法加大对小微企业的支持力度。     

低碳背景下节能减排对分行业就业影响的差异——基于我国东中西三大区域的面板数据分析

低碳经济背景下,实施节能减排政策是我国转变经济发展方式、坚持可持续发展道路的必然选择.利用29个省区、直辖市的经济发展数据,通过构建面板数据模型,考察了东、中、西三大区域不同行业的能源消费与就业之间的关系.实证结果显示,在全国范围内,节能减排政策对工业和建筑业的就业将产生抑制作用,而对服务业的就业具有促进作用.同时,节能减排政策将促进中、西部地区农林牧渔业的就业,减少东部地区农林牧渔业和交通邮政业的就业,但对中、西部地区交通邮政业的就业无明显影响.最后从能源消费的角度,对我国更好地实施节能减排政策、促进劳动力就业提出了若干政策建议.     

公共政策的效果能否被准确预测?来自中国塑料袋使用限制政策的自然实验证据

本研究以塑料袋使用限制政策的实行为契机,运用自然实验方法对采用陈述性偏好法(stated preference methods)预测政策效果的外部有效性(external validity)进行检验。在该政策执行前塑料袋均免费时,运用陈述性偏好法调查预测该政策的效果,即在塑料袋被收费的假设情景下消费者对其的预测消费量;在该政策执行后塑料袋实际收费时,再次调查该政策的实际效果,即消费者的实际塑料袋消费量。因此获得了独特的数据以对预测和实际的政策效果进行比较分析。研究表明,运用陈述性偏好法能对实际政策效果提供准确预测。

内部资本市场理论前沿与研究展望

自上世纪六七十年代以来，内部资本市场理论随着企业集团这一经济组织形式的出现而不断发展，在经历了“效率之争”后，国外有关企业集团内部资本市场理论的研究呈现出了新的发展趋势，在研究视角、研究内容、研究样本、研究方法等方面均有所突破。本文总结并梳理了外文期刊中有关内部资本市场理论的重点文献，并按照研究内容分为内部资本市场与多元化、内部资本市场中的代理问题、内部资本市场运行的经济后果、内部资本市场与外部经济环境的互动关系以及特定企业集团的内部资本市场研究五个专题分别展开论述。在此基础之上，结合我国的制度背景、时代背景和企业集团发展现状提出有价值的未来研究方向。     

浅谈保险资金投资REITs

2009年10月1日,新修订的《保险法》允许保险资金可以投资于不动产,房地产作为不动产内容之一,可以成为保险资金投资渠道之一。REITs作为房地产市场股权投资的一种方式,具有非关联性、高流动性和高回报率的特点,这与保险经营具有的强外部性、成本滞后性、资金运转周期长等特点相吻合,为保险资金投资房地产搭建了难得的操作平台。通过分析保险资金投资REITs存在风险,并给出相关建议,对我国保险资金投资REITs发展起到一定的指导作用。     

Codes of Ethics in Hong Kong: Their Adoption and Impact in the Run up to the 1997 Transition of Sovereignty to China

Following a government campaign run by the Independent Commission Against Corruption (ICAC) in 1994, many Hong Kong companies and trade associations adopted written codes of conduct. The research study reported here examines how and why companies responded, and assesses the impact of code adoption on the moral climate of code adopters. The research involved (a) initial questionnaire surveys to which 184 organisations replied, (b) longitudinal questionnaire-based assessments of moral ethos and conduct in a focal sample of 17 code adopting companies, (c) interviews with 33 managers in the focal companies examining the adoption and impact of the codes, and (d) content analysis of 41 company codes of conduct, including those of most focal companies, plus the ICAC model code.While a mixture of prudential and altruistic reasons were given for code adoption, content analysis suggested that the prime motive was corporate self-defence. The prevailing themes were bribery, conflict of interest, insider information, gambling, moonlighting, accuracy of records and misuse of corporate assets. Wider social responsibility tended to be neglected. Companies appeared to have imposed their codes top-down, emphasising disciplinary procedures rather than ethics training, and appointing neither ethics counsellors nor ombuds-people. The longitudinal study over a seven month period suggested that while moral ethos may have declined, overall standards of perceived conduct had not changed.
