居民收入差距与财政政策的关联度

改革开放以来,我国城乡经济获得较大的发展,城乡居民的收入水平有了很大的提高,城乡关系也得到了逐步改善,但城乡居民收入差距过大问题依然存在。财政是政府发挥作用的重要方式和手段,有其不可替代的功能,在缩小城乡居民收入差距、促进农民增收过程中担负着重要使命。建议加大财政对农业的总量投入,优化财政支农资金结构,加大财政对农村公共品供给的投入,完善现行财政管理体制。     

Behavior patterns of investment strategies under Roy’s safety-first principle

The safety-first principle is a natural motivational factor in decision making, and is closely related to certain popular heuristics such as satisficing. We provide a systematic analysis of optimal portfolio choice under Roy’s safety-first principle by examining and comparing the behavior patterns of three popular investment strategies: the optimal constant-rebalanced portfolio, dynamic-rebalanced portfolio and buy-and-hold strategies. Our results indicate the importance of a match between the investment strategy, the investment goal, and the investment horizon. We also develop a geometric approach to investigate the relationships among the safety-first, expected utility, and mean-variance models and offer an explanation for the long-standing debate concerning different patterns of time-diversification effects.     

融入策划思想的规划思路探讨——以同里景区控制性规划为例

经济全球化的大背景下,投资体制、资源和利益分配体制都快速的摆脱原来计划经济的轨道,越来越受市场规律的引导和制约,在投资渠道越来越多元的今天,建设程序也有了很大的不同,这些变革都要求我们在规划过程中打破原来以物质空问规划为重心的规划方式,全方位的革新规划的技术方法和思路.为了在规划过程中真正理解规划实施的最重要因素"市场需求",我们尝试在同里景区控制性规划中借鉴市场营销等方面的理论,引入市场策划的思想,力求让规划成果兼顾投资方利益以及公共利益,使之在实施过程中具有更高的可行性和可操作性.

Computing DSGE models with recursive preferences and stochastic volatility

This paper compares different solution methods for computing the equilibrium of dynamic stochastic general equilibrium (DSGE) models with recursive preferences such as those in Epstein and Zin, 1989, Epstein and Zin, 1991 and stochastic volatility. Models with these two features have recently become popular, but we know little about the best ways to implement them numerically. To fill this gap, we solve the stochastic neoclassical growth model with recursive preferences and stochastic volatility using four different approaches: second- and third-order perturbation, Chebyshev polynomials, and value function iteration. We document the performance of the methods in terms of computing time, implementation complexity, and accuracy. Our main finding is that perturbations are competitive in terms of accuracy with Chebyshev polynomials and value function iteration while being several orders of magnitude faster to run. Therefore, we conclude that perturbation methods are an attractive approach for computing this class of problems.     

Bank ownership,privatization, and performance: Evidence from a transition country

This paper combines the static effect of ownership and the dynamic effect of privatization on bank performance in China over 1995–2010, reporting a significantly higher performance by private intermediaries – joint stock commercial banks and city commercial banks – relative to state-owned commercial banks. However, publicly traded banks, subject to multiple monitoring and vetting in capital markets, perform better regardless of ownership status. The privatization of banks has improved performance with respect to revenue inflow and efficiency gains in the short- or long-run (initial public offerings). The positive long-run effect is more relevant and significant for banking institutions with minority foreign ownership. Moreover, this paper innovatively estimates interest income efficiency and non-interest income efficiency at the same time. The results suggest that Chinese banks are much more efficient in generating interest income than raising non-interest revenue, although the latter aspect has improved significantly during the sample period.     

天津农村金融环境保护投融资的路径优化研究

农村环境保护是事关解决＂三农＂问题和城乡统筹发展的公共事业。目前资金问题已成为制约新农村建设中环境保护目标能否实现的瓶颈。本文探讨了天津新农村建设中环境保护投融资的基本现状和困境,并在此基础上试着提出优化天津农村环境保护投融资路径的建议,包括引入多元化的投融资主体和方式、完善投资回报补偿机制、建立城区补偿农村环境机制以及完善投融资的政策法规保障等。     

征信体系的作用与效率——基于信息不对称随机有限重复博弈的分析

征信体系的意义可以用重复博弈理论来加以解释.本文建立了一个信息不对称随机有限重复信用博弈模型,证明如果存在征信体系实现的信息共享机制,那么不论借款者的类型是什么,诚实守信是可以作为序列均衡的结果在有限重复博弈的绝大多数时期中出现的.如果不存在信息共享机制,信贷市场有可能消失,即便引入资产抵押,信贷市场仍是不完全的.基于上述序列均衡分析,本文进一步阐释了全面征信、法律保障、市场结构对征信体系效率运行的重要性.就发展中国家而言,成立中性、独立、信息全面的国家信用局和鼓励民营信用公司积极竞争,完善义务征信的法律体系是较为理想和可行的选择     

论市场经济条件下行政伦理的趋向性选择

行政管理者伦理素质水平的高低,在很大程度上会决定其在行政管理过程中、特别是行政决策中的能力和水平。不同社会政治经济条件下,行政伦理的趋向性要求会有不同。随着我国政治经济体制从计划经济体制转变到了市场经济体制,行政伦理的要求和衡量标准也会有较大的区别,全面地认识和探讨市场经济条件下行政伦理的趋向性问题,对于我们更自觉的进行行政伦理的建设很有现实意义。
