西部国债政策研究

西部大开发以来,国债政策较好地促进了西部经济增长和结构优化,但存在国债资金使用效益低下、债转贷资金归还难、债务风险较大以及积极财政政策淡出带来的资金短缺等问题。近期内国债政策仍然是促进西部经济发展的主要手段。应严格国债资金管理,发挥国债资金导向作用;改革债转贷制度,允许有条件的地方政府发行公债;并有效防范和控制地方政府债务风险。     

Research productivity patterns in the organizational behavior and human resource management literature

Closely following the analysis approach used for similar studies in the economics and finance literature, we present the first study to examine if there exists an empirical regularity in the bibliometric patterns of research productivity in the organizational behavior (OB) and human resource management (HRM) literature. Our results present strong evidence that there indeed exists a distinct empirical regularity. It is the so-called Generalized Lotka's Law of scientific productivity pattern: The number of authors publishing n papers is about 1/n^c of those publishing one paper. The observed pattern in the OB and HRM area is interestingly very consistent with those in much older, related business disciplines.     

One-step R-estimation in linear models with stable errors

Classical estimation techniques for linear models either are inconsistent, or perform rather poorly, under α$\alpha$-stable error densities; most of them are not even rate-optimal. In this paper, we propose an original one-step R-estimation method and investigate its asymptotic performances under stable densities. Contrary to traditional least squares, the proposed R-estimators remain root-n$n$ consistent (the optimal rate) under the whole family of stable distributions, irrespective of their asymmetry and tail index. While parametric stable-likelihood estimation, due to the absence of a closed form for stable densities, is quite cumbersome, our method allows us to construct estimators reaching the parametric efficiency bounds associated with any prescribed values (_α0,_b0)$({\alpha }_0,b_0)$ of the tail index α$\alpha$ and skewness parameter b$b$, while preserving root-n$n$ consistency under any (α,b)$(\alpha ,b)$ as well as under usual light-tailed densities. The method furthermore avoids all forms of multidimensional argmin computation. Simulations confirm its excellent finite-sample performances.

Asymptotic properties of MLE and UMVUE in one-parameter truncated distributions

Consider one-parameter families of continuous distributions whose range depend on an unknown parameter. In case a single sufficient and complete statistic exists, we obtain the limiting distributions of MLE and UMVUE. Both distributions are different transformations of a standard exponential variable.     

Multivariate stable ARMA processes with time dependent coefficients

This paper considers the class of m-variate autoregressive moving average (ARMA) processes with stable innovations and time dependent coefficients. A set of suitable AR and MA regularity conditions is given to ensure existence and uniqueness of valid solutions. A simple form of the above solution is expressed in terms of one sided Green's matrix functions associated with the AR operator. We solve the prediction problem arising in this class of models. A few examples are added to support the general theory.     

Uncertainty and the size distribution of rewards from innovation

 Previous research has shown that the distribution of profit outcomes from technological innovations is highly skew. This paper builds upon those detailed findings to ask: what stochastic processes can plausibly be inferred to have generated the observed distributions? After reviewing the evidence, this paper reports on several stochastic model simulations, including a pure Gibrat random walk with monthly changes approximating those observed for high-technology startup company stocks and a more richly specified model blending internal and external market uncertainties. The most highly specified simulations suggest that the set of profit potentials tapped by innovators is itself skew-distributed and that the number of entrants into innovation races is more likely to be independent of market size than stochastically dependent upon it.     

不能把"社会主义初级阶段"混同于"共产主义社会第一阶段"--与方生同志商榷

社会主义初级阶段≠共产主义社会第一阶段,两者是完全不同领域的范畴;马克思所论述的旧社会痕迹≠社会主义初级阶段存在的非公有制经济.     

基于进化博弈的战略网络节点间信任关系研究

信任是战略网络生存和进化的基础,对战略网络的治理有重要作用。文章从信任博弈双方的有限理性出发,建立战略网络节点间信任行为的进化博弈模型,并分析博弈双方的进化稳定策略。进化博弈的稳定策略分析结果说明,节点企业为了实现长期利益,最优的策略选择就是提高彼此间的信任度。     

成都农业转移人口市民化问题研究

作为西部特大中心城市,成都常住人口城镇化加速与农业转移人口市民化滞后并存。农业转移人口市民化面临的主要问题是农民工就业稳定性差、城市居住现实和居住意愿之间差距大和城市融入任重道远。应推进以人为核心的新型城镇化,继续深化户籍制度改革,拓宽住房保障渠道,坚持工业化和城镇化良性互动,注重农民工城市融合,有重点分步骤解决好农业转移人口市民化问题。
