唐朝均田制度实施成本剖析

唐初政府实行均田制缘于维持政权合法性、获取财政收入以及争夺劳动力的需要。均田制作为一种制度安排,在唐前期相对于其他可能的土地制度来讲是先进的,产生了较好的经济效益和社会效益。唐中叶后政府放弃对土地资源配置这一传统职能,不仅是社会、政治、经济发展的必然,更是唐政府在对收益与成本权衡的最终抉择。当均田制度下的交易费用逐渐增大而制度收益却逐渐减少且最终成本大于收益时,放弃旧制度无疑是一种明智的选择。     

Beyond the make-or-buy dichotomy: outsourcing creativity in the fashion sector

Both a resource-based view and transaction cost economics perspective point to firms deciding to either make-or-buy an input. In practice, this tends to result in low-skill functions being outsourced while those of higher value are retained. In this article, we explore a situation counter to the prevailing literature. We study a highly creative industry – fashion – and discover the relationship between core competence and outsourcing is not as simple as previously conceptualised. Creativity, fashion's assumed competency, rather than being guarded within a firm is instead often outsourced or borrowed. More mundane tasks such as marketing and logistics are what each firm rather develops. The effects of resulting co-dependencies are mapped and analysed in order to offer managerial insight as well as contribute to discussion within the outsourcing and resource based literatures.     

Universal equation for the relative change in profit of manufacturing company

In contemporary conditions of the company's business operations, where high dynamics of costs, sales volume and change of production programme is present, it is of crucial importance to investigate their effects on the change of profit. Starting from cost–volume–profit equation, the aim is to arrive at a universal equation that will simultaneously measure a relative change in profit for a number of products, not only under the influence of change in sales volume but also of other relevant variables, such as sales price, fixed and variable costs. The basic hypothesis is that it is possible to establish in a form of universal equation the dependence between the change in profit and change in influential variables. In this investigation, first it was observed the partial influence of some variables on the change in profit and their dependence was determined for a single product, and then for more than one product. Finally, by summing up all those effects, a universal equation of profit change was obtained. The derived universal equation for the relative change in profit along with simultaneous effects of several variables makes possible for the company management to more simply determine the profit for diverse conditions of business operations. The universal equation for the relative change in profit was applied in one company and the results obtained confirm its significance.

社会成本规避中的政策选择悖论——以济南市前屯居“旧村改造”为个案

旧村改造是城市化土地扩张的政策推进过程。由于土地、产权等相关制度建构的先天缺陷,开发主体行为能力的不足,地方政府与企业常常对改造的社会成本采取规避的态度。社会成本规避与转嫁带来了一系列的不良后果,从而形成了政策选择上的悖论。

Can institutional investors fix the corporate governance problem? Some Danish evidence

It has been advocated within corporate governance that institutional investors may discipline management in listed firms and thereby alleviate the free rider problem associated with dispersed ownership. This article tests this hypothesis using a sample of Danish listed firms during 1998–2001 determining, whether ownership by institutional investors impacts performance, measured by Tobin’s q. Using three stage least squares, it is shown that aggregate ownership by institutional investors does not influence firm performance. However, when decomposing the results, it is found that joint ownership by the largest two Danish institutional investors, has a significant negative impact firm performance. Ownership by banks and to a lesser extent insurance companies significantly influences firm performance positively. The results somehow challenge the conventional wisdom, arguing that the black box view of institutional investors should be abandon. Therefore it is suggested that a more careful analysis should be devoted to each institutional investors own legal environment.

Organisational Learning and Governance Through Embedded Practices

This article has two principal aims. The first is to reconcile thecompetence based approach to the firm with traditional contractualapproaches, instead of treating them as incompatible. The mainthesis advanced is that firms manage simultaneously competencesand transactions, but they do so in accordance with a specificlexicographic order of priorities. The second aim is to explorein detail the sources of knowledge formation in the firm. Theanalysis privileges anthropological readings which stress the roleof learning – both radical and incremental – within distributed communities of practice.
