In conducting a longitudinal examination of eight long-term complex decision processes in two Fortune 500 heavy manufacturing companies the authors developed a six-level framework of decision complexity. The levels range from: (1) instantaneous decision choices to (2) decision actions (3) decision events (4) mini-decision processes (5) decision processes and (6) decision theatres. They vary in time, numbers of participants, and in the integrative effort required to formulate and implement them. Thus, one problem with the word ‘decision’is that it is used to mean many different things in organizational settings. Each lower level of ‘decision’was found to combine with ‘decisions’of the same level and to be embedded within higher levels, resulting in a nested hierarchy of simultaneously occurring processes.  相似文献

Transport infrastructure is an important subsector within infrastructure, but knowledge of its equities in terms of risk-return characteristics and contribution to portfolio performance is still limited. This study assesses the subsector individually and in a multi-asset, index-based portfolio. In doing so, we apply a t-Copula-based Conditional Value-at-Risk model to simulate risk and returns. Our findings reveal that the subsector has a relatively low dependency on other equities, performs like other alternative asset classes such as general real estate, and does not grant significant risk diversification benefits for mainstream institutional investors such as pension funds. Investors aiming for higher target returns may however assign substantial weights to transport infrastructure, supporting our conjecture that it does not share the same asset class characteristics as general infrastructure. By contrasting Value-at-Risk (VaR) and Conditional Value-at-Risk (CVaR) scores for both the mean-variance framework and the t-Copula simulation, we further document the limitations of traditional VaR approaches. Hence, this study’s results support the use of risk assessment tools that incorporate non-normal distributions to represent multivariate dependence structures.  相似文献

This paper investigates changes in factors bearing on technology adoption decisions in small manufacturing firms. It is hypothesized that, as a firm's experience with technology increases and its technological capabilities grow, the decision process is gradually modified and puts more weight on those factors which are more closely related to the true potential of the technology. An empirical study shows the more innovative firms to have an outward orientation dominated by clients and suppliers, and to pay more attention to the added flexibility brought about by new technology. It is also shown that functional groups within the company play a more important role in the decision-making process.  相似文献

The paper analyzes empirical evidence from 368 environmentally responsive small and medium-sized enterprises (SMEs) operating in four industries. The results demonstrate that firms' environmental performance cannot be viewed as a one-dimensional concept and that determinants of firms' environmental performance depend on the dimension retained. The impacts of firms' environmental performance on their innovativeness and competitiveness vary according to the industry within which they operate. However, impacts on product and process innovations as well as on managerial innovations are positive and significant in all four industries.  相似文献

The price-oriented experience curve has been widely utilized as a model to design marketing strategies. Yet, it is cost over which many firms exercise the most control. This article explores the cost-oriented learning curve in conjunction with the product life cycle model as joint strategy constructs. Implications of variations in the learning curve parameters are examined.  相似文献

Although multi-national corporations have been one of the main customers for future-oriented activities such as technological forecasting, precious little attention has been paid to their development either in the work of the so-called establishment futurists or in the work of their more ‘radical’ colleagues. It is argued that these companies will be increasingly free of control at the international level though under greater scrutiny at the national level. It is likely that they will become increasingly intertwined with both national and international governing bodies, and be seen as arms of these governing bodies rather than as the traditional profit-maximising organisations.  相似文献

This study presents a full model of the labor market under imperfect information. Workers bear the burden of search and are assumed to use a stochastic variant of an optimal sample size search strategy. The existence and uniqueness of a nondegenerate equilibrium distribution of wage offers is established. Infficiencies which lead to underinvestment in search are uncovered and analyzed.  相似文献
