长江上游地区产业结构演进与经济协调发展分析

文章对长江上游地区1991～2007年三次产业结构的演进特征进行分析,研究了其与经济发展的关系。结果表明,长江上游地区产业结构经历了从一、二、三型向二、一、三型转变,目前维持在二、三、一型的变化过程。产业结构整体水平落后于全国平均水平,但产业结构演进基本与工业化进程保持一致,且产业结构升级速度超过全国乃至东部地区,具有比东部地区更为强大的产业结构演变动力;产业结构转换与经济发展协调程度表现出地区差异,38%的城市产业结构转换超前于经济发展水平,60%的城市产业结构转换与经济发展水平相协调,2%的城市产业结构转换滞后于经济发展水平。     

Reaffirming the CEO effect is significant and much larger than chance: A comment on Fitza (2014)

A recent study by Fitza argued that the prior estimates of the Chief Executive Officer (CEO) effect are conflated with events outside the CEO's control, are largely the result of random chance, and that the true CEO effect is smaller than has been previously estimated. We suggest that the empirical methodology employed by Fitza to support these claims substantially overstates the “random chance” element of the CEO effect. We replicate Fitza's findings, highlight methodological issues, offer alternative conclusions, and using multilevel modeling (MLM), suggest that his analyses mischaracterize the CEO effect.

上部结构与地基基础的共同作用

上部结构与地基、基础是紧密联系的一个整体,在工程设计中,设计人员经常忽略地基、基础与上部结构的相互作用,人为地把地基、基础和上部结构隔离计算,既不经济,也不安全。文章主要探讨高层结构与地基基础相互作用情况,提出在设计中考虑地基、基础与上部结构共同作用的重要性。     

A model of person‐pay interaction: how executives vary in their responses to compensation arrangements

A wealth of research indicates that both executive characteristics and incentive compensation affect organizational outcomes, but the literatures within these two domains have followed distinct, separate paths. Our paper provides a framework for integrating these two perspectives. We introduce a new model that specifies how executive characteristics and incentives operate in tandem to influence strategic decisions and firm performance. We then illustrate our model by portraying how executive characteristics interact with a specific type of pay instrument—stock options—to affect executive behaviors and organizational outcomes. Focusing on three individual‐level attributes (executive motives and drives, cognitive frame, and self‐confidence), we develop propositions detailing how executives will vary in their risk‐taking behaviors in response to stock options. We further argue that stock options will amplify the implications of executive ability, such that option‐heavy incentive schemes will increase the performance of talented executives but worsen the performance of low‐ability executives. Our framework and propositions are meant to provide a starting point for future theorizing and empirical testing of the interactive effects of executive characteristics and incentive compensation on strategic decisions and organizational performance.

A characterization of exact non-atomic market games

Continuous exact non-atomic games are naturally associated to certain operators between Banach spaces. It thus makes sense to study games by means of the corresponding operators. We characterize non-atomic exact market games in terms of the properties of the associated operators. We also prove a separation theorem for weak compact sets of countably additive non-atomic measures, which is of independent interest.

Sequential American Exchange Property Options

Property development activities often occur in stages, which are appropriately modeled as sequential American exchange property options, where there are interim expenditures required in order to keep the property development options “alive”. Normally American exchange options require a numerical solution, but herein there is a new closed-form approximate solution, which is computationally efficient and accurate. This method combines repeats of Margrabe European exchange and Geske compound option solutions with tight upper boundaries of either American perpetuities or European exchange options with a high volatility. Illustrations are provided of the sensitivity of the real sequential options and optimal timing to changes in several parameters, which provide a framework for property policy (tax, subsidy and regulatory) guidelines and for property development strategy evaluation. There are several plausible applications of these real option models in commercial and residential property development, within commercial property leases, with regard to switching tenants, and agricultural alternatives.

Predicting organizational identification at the CEO level

To develop further insight into antecedents of the CEO's psychological orientation toward the firm, we investigate what might lead CEOs to identify with their firms. Although research suggests that CEO organizational identification can be quite consequential for the firm, little research attention has been paid to its determinants. To predict how the special context of the CEO position might lead to identification, we consider a set of motives that members have for identifying with their organizations and consider how unique features of the CEO position might be relevant to those motives. Our theory and supportive findings help explain how the context of the CEO position, including variables often conceptualized as control mechanisms in agency theory research, can have important effects on subsequent CEO organizational identification.
