关于重大工程编制移民安置规划并建立监测制度的思考

在移民安置量较大的建设工程准备阶段和实施阶段,可以考虑参照工程建设审批程序和实施过程中的质量监理制度,建立规范的移民安置规划审批制度和移民安置监测制度.移民安置规划制度从程序和内容对移民安置准备工作提出具体要求.对移民安置的实施要引入独立的外部监测机构,对安置工作进行监测评估.     

Communication equilibrium payoffs in repeated games with imperfect monitoring

We characterize the set of communication equilibrium payoffs of any undiscounted repeated matrix-game with imperfect monitoring and complete information. For two-player games, a characterization is provided by Mertens, Sorin, and Zamir (Repeated games, Part A (1994) CORE DP 9420), mainly using Lehrer's (Math. Operations Res. (1992) 175) result for correlated equilibria. The main result of this paper is to extend this characterization to the n-player case. The proof of the characterization relies on an analogy with an auxiliary 2-player repeated game with incomplete information and imperfect monitoring. We use Kohlberg's (Int. J. Game Theory (1975) 7) result to construct explicitly a canonical communication device for each communication equilibrium payoff.

How Do Institutional Investors Affect Corporate Performance? Evidence from Private Placements in China

Using data on private placements in China from 2007 to 2014, we show that abnormal returns of issuing companies’ stocks are significantly positive on the announcement day, but they become significantly negative during the event window [?20, +20]. Participation by institutional investors has a significant and negative impact on the short-term stock returns. This negative effect is also present in issuing companies’ long-term stock returns and profitability. Furthermore, we find that participation by institutional investors reduces dividend payments after private placements. Overall, our findings do not support the monitoring hypothesis of institutional investors’ role in corporate finance but are consistent with the management entrenchment hypothesis and shareholder pessimism hypothesis.

经济学视角下自然保护区有效管理行为研究——以甘肃白水江自然保护区李子坝社区为例

以甘肃白水江自然保护区李子坝社区巡护监测为例,从经济学的视角,运用比较优势和竞合模型分析该社区巡护监测与专业巡护监测的两种行为。模型分析显示两者各有优势,在专业巡护监测的基础上,如果辅之以社区巡护监测能更有效地促进环境与生物的多样性的保护,既可以提升有效管理的水平,又可以达到社区保护利益的最大化。     

我国能耗监测管理现状及未来发展趋势

适应节能形势发展的新变化,能耗监测的内涵也正在逐步延伸。实践表明,建立有效的能耗监测管控体系,对于提高能效、推进节能减排作用明显。近年来我国能耗监测管理得到了不同程度的改善,但在管理理念、制度安排、技术创新、资金支持等方面还存在着较多问题。利用信息技术,建立能耗在线实时监测管理体系,将成为未来能耗监测的发展目标。适应这种发展要求,我国需要在计量设备基础管理、能耗监测考核制度、监测机构设置和人员培训、资金渠道等方面进行不断创新。     

Disclosure‐protected Inference Using Generalised Linear Models

Vast amounts of data that could be used in the development and evaluation of policy for the benefit of society are collected by statistical agencies. It is therefore no surprise that there is very strong demand from analysts, within business, government, universities and other organisations, to access such data. When allowing access to micro‐data, a statistical agency is obliged, often legally, to ensure that it is unlikely to result in the disclosure of information about a particular person or organisation. Managing the risk of disclosure is referred to as statistical disclosure control (SDC). This paper describes an approach to SDC for output from analysis using generalised linear models, including estimates of regression parameters and their variances, diagnostic statistics and plots. The Australian Bureau of Statistics has implemented the approach in a remote analysis system, which returns analysis output from remotely submitted queries. A framework for measuring disclosure risk associated with a remote server is proposed. The disclosure risk and utility of approach are measured in two real‐life case studies and in simulation.
