不完全竞争市场中信息相关性对资本成本的影响

从投资者理性预期出发,以不完全竞争市场和信息相关为前提,以市场微结构理论和投资者信息解读理论为基础,构建了信息披露质量和投资者信息解读能力影响资本成本的模型。研究发现：在非流动性程度及个人投资者解读信息精确度给定条件下,资本市场的均衡是唯一存在的;在其他条件不变的前提下,市场非流动性程度通过投资者的平均信息解读能力和流动性影响因子两个途径影响着资本成本。     

Participatory action research on HIV/AIDS through a popular theatre approach in Tanzania

A participatory theatre approach stimulated communities to break the silence about sexual and cultural practices leading to HIV transmission, and then to openly discuss what they could do to reduce transmission. Participants were district officials, artists, village and ward leaders, youths, and entire communities. Community theatre specialists trained young community members in participatory research and theatre. These artists then researched and encouraged people in their communities to discuss and evaluate the factors contributing to HIV transmission in their communities. Discussion results were transformed into community and district level performances. This was a very successful IEC effort that identified key risk behaviours and locally developed culturally appropriate, relevant materials, delivered in a popular way. People reflected upon their situation and behaviour, and community leaders addressed harmful practices. Feedback sessions were held with co-ordinators and artists to record lessons learned and make recommendations for improving and expanding the programme.

投资者的信息解释能力对股票交易量的影响

基于对投资者精明度内涵的新认识——信息解释能力理论,文章构建了投资者的信息解释精度影响市场交易量的模型,尝试从不同视角探讨投资者信息解释能力对股票交易量的影响。研究发现：投资者的信息解释能力及其信息解释精度影响着交易量的变化。具体而言,交易量与买卖双方信息解释能力的差异正相关;当新信息披露时,投资者的信息解释能力越强,或专业投资者的比例越大,交易量将越小;专业投资者的信息解释能力越强,且与非专业投资者的差异越大,或专业投资者的比例越小,交易量将越大。     

投资者信息解释能力对资本成本的影响探析

基于投资者信息解释能力理论，文章构建了投资者信息解释能力影响资本成本的理论模型，尝试从不同视角探讨投资者信息解释能力对资本成本的影响。研究发现：不同投资者信息解释能力的差异是影响其所要求预期收益即资本成本的重要原因之一。
