西方价值管理之批判:新制度主义的视野

20世纪80年代以来,价值管理逐渐成为西方管理界最为盛行的一种管理思潮。本文从新制度主义的视角对西方价值管理的理财环境变化、价值管理目标、权力配置和理论前提进行了批判,阐述了价值管理的个体主义方法论存在系统观念和伦理价值缺乏,导致企业内在价值丧失的局限性,提出价值管理必将向融合利益相关者的一种新型价值管理模式转化,为我国价值管理模式的构建和发展提供启发。

多重网络嵌入对集群企业创新能力的作用

以集群企业作为研究对象,将企业规模和网络客体对象的差异作为情景变量,考察了多重网络嵌入：集群内外商业网络和技术网络关系嵌入强度对其创新能力的作用。通过实证分析后发现,集群内外商业网络和技术网络的关系强度,对集群内大企业和中小企业的探索性和利用性创新的作用具有显著差异,在作用方向和程度上都具有明显区别,同时,这种作用还受到强关系对象中是否具有较多大企业的调节。     

Embedded Enclaves: Cultural Mimicry and Urban Social Exclusion in Iran

This article argues that symbolic boundaries and their spatial manifestation into embedded enclaves have become new forms of urban social exclusion. Based on participant observation and interviews among lower‐ and middle‐/upper‐class residents in the city of Sari, Iran, the article analyzes how the poor's physical circulations in the city and their performances of class and status have led to an elite backlash, as the latter find more refined markers of social separation in an effort to bolster their own exclusivity. Social distancing through the denigration of the poor and the construction of embedded enclaves brings to the fore the class tensions that are temporarily masked by the urban poor's spatial practices and cultural mimicry. As an advanced form of codified status inequality, embedded enclaves rely on the poor's citywide circulations and on increasing inter‐class interactions in order to communicate difference. Embedded—rather than cordoned off—in prominent areas of the city, such enclaves function as a reminder to the poor of all they cannot have. The upsurge of such establishments in the wake of Iran's shifting economic environment represents an attempt to shore up social position and restore the status quo.

A generalized algorithm for duration and convexity of option embedded bonds

This article derives a generalized algorithm for duration and convexity of option embedded bonds that provides a convenient way of estimating the dollar value of 1 basis point change in yield known as DV01, an important metric in the bond market. As delta approaches 1, duration of callable bonds approaches zero once the bond is called. However, when the delta is zero, the short call is worthless and duration of callable will be equal to that of a straight bond. On the other hand, the convexity of a callable bond follows the same behaviour when the delta is 1 as shown in Dunetz and Mahoney (1988) as well as in Mehran and Homaifar’s (1993) derivations. However, in the case when delta is zero, the convexity of a callable bond approaches zero as well, which is in stark contrast to the non-zero convexity derived in Dunetz and Mahoney’s paper. Our generalized algorithm shows that duration and convexity nearly symmetrically underestimate (overestimate) the actual price change by 11/10 basis points for ± 100 basis points change in yield. Furthermore, our algorithm reduces to that of MH for convertible bonds assuming the convertible bond is not callable.
