Dimensions of uncertainty and their moderating effect on new product development project performance
In this study, we measure the dimensions of uncertainty, starting from the definitions constructed for and generally used in innovation projects. We then evaluate their direct and indirect effects on the performance of product and service development projects. Four dimensions of uncertainty are delimited with satisfactory validity and reliability, suggesting a differential moderating effect of the four types of uncertainty (technical and project uncertainty, market uncertainty, fuzziness and complexity) depending on the performance dimension (effectiveness and efficiency) and co‐moderator (project methods and human resource adequacy). Of the four dimensions explored, technical and project, and market uncertainty are true moderators and have the largest interactive effect, fuzziness has a strong direct effect on both performance dimensions whereas complexity weakly directly influences effectiveness. The latter two also influence the relations between performance and the factors related to human resources and project management methods. 相似文献

Questionnaire data were obtained from 128 managers representing all levels and functions of a large manufacturer. Variables describing the superior/subordinate relationship were related to respondent's perceptions of the values of management by objectives using correlational methods. These relationships were then moderated using personality and situational characteristics of the respondents.

This paper introduces a new framework to characterize the diversity of public policies and interventions to spur investment and growth. Going beyond ideological cleavages on this topic, we argue that two orthogonal features determine how much interventions depart fundamentally from neutral policies: (1) their degree of selectivity (in terms of sectors or other targeted categories of firms) and (2) the extent of price subsidies embedded in such interventions. These two characteristics of interventions respond to different types of justifications, and they do not necessarily need to go hand in hand, even if they often do in practice. Depending on their selectivity and/or the extent of price subsidies, interventions are shown to vary in their distortions, their benefits, and their opportunity costs. The framework is used to illustrate how different country characteristics affect these pros and cons of interventionism. In particular, we look at the effects of the initial state of the investment climate, the country's institutional capacity, its political economy context and the nature of the State-business interaction. Using the examples of poor countries with a small undiversified industrial base, we show that it is often in the situations where interventions may be the most needed, that the conditions for their success are likely to be the weakest, which does not mean either that some interventions cannot succeed in low-income countries. 相似文献

This paper studies the exchange rate dynamics of the Mozambique metical with respect to the US dollar and the South African rand. However, instead of using standard I(0)/I(1) techniques, we use long memory and fractionally integrated and co‐integrated models. Our results indicate that the two exchange rates are highly persistent, with orders of integration equal to or above 1. They also seem to be co‐integrated, with an order of integration close to albeit above 0 but with an AR coefficient very close to 1. Thus, although the two series seem to be fractionally co‐integrated, shocks in the long‐run relationship between the two variables are persistent and take a long time to disappear. 相似文献

The European Union Emissions Trading System (EU ETS) is in dire straits. Prone to design problems and suffering from the effects of the economic crises the scheme is criticised for its poor achievements. In this paper we will analyse some of the features of this situation from an ethical perspective. The major part is dedicated to the complications within each phase of the EU ETS and to the recent developments it has undergone. We will briefly discuss the remedies suggested by prominent commentators. Furthermore, any policy tool to tackle climate change should be evaluated in view of the profound equity issues that are inherent to the climate problem. We will evaluate the EU ETS according to two justice-based criteria, related to effectiveness and the distribution of the duties involved in climate change, respectively. We will conclude that the EU ETS, in its current form, clearly lacks fairness on both criteria. However, the biggest problem is the unwillingness of EU leaders to mend, what could be, a commendable climate policy tool. To that extent, we argue, those leaders are acting unjustly. 相似文献

Looking Forward to Performance Improvement: A Field Test of the Feedforward Interview for Performance Management

This study examines the effectiveness of the feedforward interview for improving the job performance of employees relative to a traditional performance appraisal interview in a business equipment firm. Managers (n = 25) were randomly assigned to one of two conditions. Employees (n = 70) who engaged in a feedforward interview with their manager were observed by an anonymous peer to perform significantly better on the job four months later than employees (n = 75) who received the company's traditional performance appraisal interview. The finding that the feedforward intervention increased performance relative to the performance appraisal indicates that the effect is a relatively enduring one. The results suggest that the feedforward interview should prove useful for human resource managers who are searching for ways to increase the performance of their organization's human resources over and above the traditional performance appraisal. © 2014 Wiley Periodicals, Inc. 相似文献
