Evaluation of the performance of GDSSs has been dominated by an experimental and laboratory based approach. Other writers have argued for evaluation to be based in the “real-world” of decision making teams. The evaluation criteria have tended to ignore many of the issues that would be paramount for some of the stakeholders in the evaluation process. This article seeks to explore the criteria that might be used by a wide variety of stakeholders, including developers, facilitators, clients, key actors, vendors, as well as academics. By drawing together the criteria associated with all of the stakeholders we discover a broader, and possibly more thorough, framework for evaluation. The evaluation of any particular GDSS in relation to other GDSSs can then be seen in the context of contingent weighting applied to each of the criteria where each GDSS is able to be seen in its best light and in relation to its declared aims. This article argues for a more eclectic and contingent approach to the evaluation of GDSSs which will encourage their future development to be clearer about purpose and the boundaries of their use.  相似文献

The concept of entrepreneurial ecosystems has quickly established itself as one of the latest ‘fads’ in entrepreneurship research. At face value, this kind of systemic approach to entrepreneurship offers a new and distinctive path for scholars and policy makers to help understand and foster growth-oriented entrepreneurship. However, its lack of specification and conceptual limitations has undoubtedly hindered our understanding of these complex organisms. Indeed, the rapid adoption of the concept has tended to overlook the heterogeneous nature of ecosystems. This paper provides a critical review and conceptualisation of the ecosystems concept: it unpacks the dynamics of the concept; outlines its theoretical limitations; measurement approaches and use in policy-making. It sets out a preliminary taxonomy of different archetypal ecosystems. The paper concludes that entrepreneurial ecosystems are a highly variegated, multi-actor and multi-scalar phenomenon, requiring bespoke policy interventions.  相似文献

This study provides further empirical investigation, in the context of giant Japanese banks, of the recent claim by Pulley and Braunstein (1992, A composite cost function for multiproduct firms with an application to economies of scope in banking, Review of Economics and Statistics 74, 221–230), that their new composite model for the multiproduct cost function has important advantages over the separable quadratic, generalized translog and standard translog models. In addition to assessing the composite model's relative ability in measuring global scope and scale economies, the study also extends the P-B analysis to assess measurement of product-specific scope and scale economies, pairwise cost complementarities between outputs, changes in the marginal costs of outputs and technological change. The results appear to confirm P-B's chain. The persistent finding of scale economies for large Japanese banks is also investigated and confirmed.  相似文献

The aim of this paper is to evaluate the prevalence in the 27 member states of the European Union of a little discussed illicit wage arrangement in which formal employees are paid two wages by their formal employers – an official declared salary and an additional undeclared wage, thus allowing employers to evade their full social insurance and tax liabilities. Reporting the results of a 2007 Eurobarometer survey involving 26,659 face‐to‐face interviews, the finding is that one in 18 formal employees received such an envelope wage from their formal employer and that envelope wage payments are more prevalent in member states with lower (rather than higher) levels of state intervention. The tentative conclusion is that illicit envelope wage payments are a product of under‐regulation, rather than over‐regulation, and that further research is now required to test the validity analysis of this thesis in other global regions.  相似文献

Evaluating the effect of soft business support upon small firm performance   总被引:2,自引:0,他引:2  
The paper applies robust econometric techniques to assess theimpact of publicly-provided subsidised ‘soft’ businesssupport on the performance of small and medium-sized enterprises(SMEs). It considers the assistance for consultancy advice providedtowards marketing under the UK Enterprise Initiative, lookingat its effect on sales turnover, employment and survival, andmaking explicit allowance for selection effects. It is foundthat the policy has no impact on the survival of smaller SMEs,and that it is most effective in the mid-range SMEs, where itraises survival rates by about 4% over the longer run and growthrates in surviving firms by up to 10% per annum. Overall, thescheme has a substantial impact, but the paper draws attentionto the possible displacement effects.  相似文献

The problems of transforming smallholder tree crops from traditional low-yielding to modern high-yielding technology are examined, using a meta production function approach to analyse the changes. The role of government in transformation is considered, and various ‘individual’ and ‘black’ improvement schemes implemented since the 1950s are analysed. Many of these schemes have not teen successful owing to poor planning and inadequate managerial and financial support, and their coverage has been small in relation to the huge areas needing improvement. The paper suggests a more modest ‘dispasal’ approach to transformation, concerned with setting up nurseries to provide better quality planting material and advice to individual fanners. But even this revised approach should be carefully planned and executed light of previous mistakes if it is to have widespread impact.  相似文献
