A risk evaluation method for the high-tech project investment based on uncertain linguistic variables

There are many uncertain factors in the high-tech project investment. It is necessary to use a scientific evaluation method in the high-tech investment. This paper proposes a risk evaluation method for a high-tech project investment. Firstly, the current situation of the research of a high-tech project investment is discussed. Then an evaluation indicators system is constructed and the evaluation procedure based on an uncertain linguistic weighted C-EOWA (ULWC-EOWA) operator is illuminated. Finally, this evaluation method is used in a practical example.

Dynamic capabilities and entrepreneurial management in large organizations: Toward a theory of the (entrepreneurial) firm

Mainstream economic theory has generally excluded consideration of the role of managers, which has, in turn, impaired its ability to explain resource allocation by, and heterogeneity among, firms. In the real world, managers are called on to fill entrepreneurial and leadership roles: sensing opportunities, developing and implementing viable business models, building capabilities, and guiding the organization through transformations. These entrepreneurial management tasks are part of the organization׳s capabilities, which also encompass embedded organizational processes that can be slow to change. An understanding of entrepreneurial management and organizational capabilities will contribute to more realistic economic models and a better understanding by policy makers of industrial dynamics and the requirements of innovation.     

Creditworthiness and thresholds in a credit market model with multiple equilibria

Summary. The paper studies creditworthiness in a model with endogenous credit cost and debt constraints. Such a model can give rise to multiple candidates for steady state equilibria. We use new analytical techniques such as dynamic programming (DP) with flexible grid size to find solutions and to locate thresholds that separate different domains of attraction. More specifically, we (1) compute present value borrowing constraints and thus creditworthiness, (2) locate thresholds where the dynamics separate to different domains of attraction, (3) show jumps in the decision variable, (4) distinguish between optimal and non-optimal steady states, (5) demonstrate how creditworthiness and thresholds change with change of the credit cost function of the debtor and (6) explore the impact of debt ceilings and consumption paths on creditworthiness.JEL Classification Numbers: C61, C63, D91, D92, E51, G12, G32.An earlier version of this paper has been prepared for the 1998 North American Winter Meeting of the Econometric Society, January 1998, Chicago.

Dynamic management view: logic of profit seeking based on adaptation to technological change and needs evolution through needs-focused innovation

Scrutinising well-known models/theories in strategic management, this paper proposes dynamic management view (DMV) on the premise profit comes from adaptation to technological change and needs evolution through needs-focused innovation in a dynamic world. It firstly sets up the theoretical framework of DMV by taking business model to embrace explicit needs (the ultimate source of profit) and needs-focused innovation (the ultimate driver of profit seeking) as the very causal mechanism at the micro-foundations level, and technological change and needs evolution as the direct causal mechanisms of profit at the macro-foundations level from which it draws the universal and contingency rules of needs-focused innovation, derives the propositions about the adaptive goodness between explicit needs and needs-focused innovation, shows it works as the determinant of profit with the industrial experiences, and concludes DMV provides the rationale for a firm’s sustainability, the strategic decision rules for business model innovation and the theoretical foundation to build dynamic theory of profit seeking.
