上市公司可持续发展有效途径的探讨

在当前资本市场中,我国上市公司的盈利能力不断提高,但是上市公司的可持续发展问题也随之而来,如何处理好我国上市公司的可持续发展问题将成为我们关注的焦点。本文从上市公司发展的动力机制出发,对我国上市公司的现状进行了论述,分析了阻碍上市公司可持续发展的原因,并提出建立上市公司可持续发展机制的有效途径。     

Non-stationary,stable Markov processes on a continuous state space

We extend our previous result on simple stable Markov (SSM) processes to the case where the state space is continuous. As anapplication we show the existence of a competitive general equilibrium of a cobweb model where price volatility is generated both by exogenous shocks and by stochastic, so called generating variables (that may be interpreted as sunspots) that govern the correlation of the rational beliefs of individual agents. I would like to thank Danish Social Science Foundation, The Carlsberg Foundation, Stanford Institute for Theoretical Economics (SITE) and Universita Cattolica for financial help. I would also like to thank Trinidad Casasus, Mordecai Kurz, an anonymous referee as well as participants at SITE, ESAM (2004) and ESEM (2004) for helpful discussions and comments. Peter Harremoes provided me with an illuminating counter example and Hiro Nakata provided many comments that helped improve the exposition of the paper. Part of this work is from a paper previously circulated under the title: “Sunspot rational belief structures: anonymity and endogenous uncertainty”.     

市场调研在产品前期设计中的运用

企业在决定开发新产品的过程中,首先需要对市场有一个全方位的了解,在理性分析和严格定位现有产品的基础上,再来进行新产品的开发设计,这样才能做到有的放矢。本文就是立足于产品前期的设计定位研究,通过对现阶段国内外调研方法的比较。总结出了一套适合目前国内企业进行产品前期设计的市场调研方法,并对其进行了可行性分析。     

新保守主义的就业理论及其启示

以货币学派、供给学派与理性预期学派为主要学派的新保守主义,对70年代以后西方国家发生的失业与通货膨胀并存的“滞胀”现象进行了新的解释。这种解释中关于就业的理论至少给我们两点启示：在我国,只有借助于政府的干预才有望较有效地解决失业同题;借助政府干预解决就业同题的重要任务之一,就是建立和健全劳动力市场。     

Persuasion under costly learning

A Sender (seller) tries to persuade a rationally inattentive Receiver (buyer) to take a particular action (e.g., buying). Learning is costly for the Receiver who can choose to process strictly less information than what the sender provides. In a binary-action binary-state model, we show that optimal disclosure involves information distortion, but to a lesser extent than the case without learning costs; meanwhile, the Receiver processes less information than what he would under full disclosure. We also find that the Receiver can leverage his potential inattention to attain a higher equilibrium payoff than the perfectly attentive case. While the Sender is always worse off when facing a less attentive Receiver, the amount of information processed in equilibrium varies with learning costs in a non-monotone fashion.     

Sequential coordination,higher-order belief dynamics and the E-stability principle

This paper explores convergence in higher-order beliefs – otherwise called eductive stability – when coordination is sequential, that is, when each agent of a given type fixes his own actions after observing the ones of earlier types in a given order. The presence of sequential types enhances expectational coordination in the case of strategic substitutability, but not in the case of strategic complementarity. In particular, eductive stability can be obtained for any degree of substitutability, provided the number of sequential types is large enough. Therefore, sequential coordination opens up to the possibility that eductive convergence occurs at the same conditions of adaptive convergence, in accordance to the E-stability principle.     

Rational inattention and revealed preference: The data-theoretic approach to economic modeling

Beliefs have as pervasive a role as utility functions in economic models of choice, and are no more visible to the naked eye. This suggests the value of a data-theoretic approach to imperfect information along the lines of Samuelson's “revealed preference” approach to utility maximization. I introduce a recently developed approach of this nature (Caplin and Martin, 2013a, Caplin and Dean, 2013a, Caplin and Dean, 2013b). I highlight the broader potential of the data-theoretic approach to answer questions of an inter-disciplinary nature and to discipline an oncoming flood of behaviorally-relevant data.     

门诊抗高血压药物应用分析

目的介绍我院门诊抗高血压药物的使用情况,为临床合理用药提供参考。方法选取我院2013年的处方,从中筛选出含有抗高血压药物的处方,采用世界卫生组织（WHO）推荐的限定日剂量（DDD）等方法进行统计、分析。结果 28 208张门诊处方中使用抗高血压药物的处方有5 005张,占总处方数的17.7%。抗高血压药物在门诊使用较多,钙通道拮抗药（CCB）使用率最高,处方中抗高血压药物多为联合用药。结论我院门诊抗高血压药物使用基本合理,大多为联合用药,但仍需进一步提高。
