A Dynamic Study on Ecological Disaster,Government Regulation,and Renewable Resources

This article develops a dynamic model to investigate renewable resource markets under different property rights. We find that different property rights regimes in renewable resource markets yield very different equilibria. Under private property rights, the valve point increases with the natural growth rate, productivity, number of firms, and marginal costs. Under common property rights, “the tragedy of the commons” inescapably occurs. This study suggests how to avoid ecological disaster by implementing a set of public policies.     

To blow or not to blow the whistle: the effects of potential harm,social pressure and organisational commitment on whistleblowing intention and behaviour

This study uses a rational ethical decision‐making framework to examine the influence of moral intensity (potential harm and social pressure) on whistleblowing intention and behaviour using organisational commitment as a moderator. A scenario was developed, and an online questionnaire was used to conduct an empirical analysis on the responses of 533 participants. The mean age and years of work experience of the respondents were 31 and 8.2 years, respectively. The results show, first, that while moral intensity is correlated with whistleblowing intention, only the potential harm is positively correlated with such intention. Second, potential harm and social pressure differentially affect whistleblower choice of using an internal or external channel. Third, organisational commitment has a moderated mediation effect among moral intensity, whistleblowing intention and behaviour. Fourth, whistleblowers may be grouped into four conceptual types: indifferent, rebel, mature and spoil. Finally, theoretical and managerial implications of the findings are discussed.     

信贷、保险、“信贷+保险”的扶贫效果比较研究

农村金融是农村经济发展的重要内生动力,创新金融扶贫体制对我国农村深度贫困地区的脱贫攻坚工作具有重要意义。本文基于多重均衡模型,对比研究信贷、保险、"信贷+保险"三类金融产品的扶贫效果,在不同的信贷和保险产品结构下得出陷贫概率,进而得出金融扶贫产品的精准设计,以创新金融扶贫体制,从而解决我国深度贫困的问题。研究表明:单独信贷产品扶贫无效;保险能够帮助阈值以上人群摆脱潜在贫困,但对深度贫困无效;"信贷+保险"能解决一定程度的深度贫困问题,比单独信贷或单独保险的扶贫效果更好。     

The trend of the Gini coefficient of China (1978–2010)

ABSTRACT

This study proposes a new approach to analyse the effects of an overlap term on the calculation of the overall Gini coefficient and estimates China’s Gini ratios since the adoption of the economic reform and open-door policies. A decomposition of the Chinese Gini coefficient for 1978–2010 reveals that the key factor contributing to income inequalities is the income disparity between rural and urban inhabitants. We further investigate the features of this income inequality between rural and urban areas and employ statistical approaches to evaluate the effects of urbanisation and rural-to-urban average income on nationwide income inequality. The results show that accelerating the pace of urbanisation is mainly responsible for decreasing China’s income disparity. Drawing on these results, we conclude with suggestions for related policies.

Monday returns and asset pricing

The seasonal patterns observed on Monday stock returns are still unexplained by different asset pricing models. We attempt to fill this gap in the finance literature by using the Fama-French (Journal of Financial Economics 33:3–56, 1993) risk factors to explain the Monday seasonal. The results in the study show that Monday returns are explained by risk factors such as the market return, the size of the firms, and the book-to-market ratios of firms.     

黄河中游流域土壤活性调查及其激活研究

研究了氢氧化钠、水玻璃、氢氟酸和磷酸对黄河中游不同地区土壤的侵蚀激活效果,结果表明,磷酸对土有很好的激活作用,掺入磷酸的土做成试件抗压强度较不掺加磷酸的土有很大提高,并且随着磷酸掺量的增多,强度继续增长,耐水性也有很大改善。红外及微观分析表明,磷酸能够改变土粒表面的羟基团,并且磷酸与土中的碳酸盐等生成肉丝状的磷酸钙晶体,分布在土粒的周围,胶结土壤。
