In this article, we suggest that organizations should not focus on selecting between various project management approaches, tools, or behaviors. Instead, we claim that the real benefit from project management implementations comes from the mere creation of a common frame of reference. Based on four case studies, we identify elements that enhance such a common frame of reference: (1) a common project management model, (2) common project management training, (3) common project management examinations/certifications, and (4) activities for knowledge sharing. Values created, especially when the application of the elements was mandatory, were better communication, better customer satisfaction, and easier knowledge sharing.  相似文献

Over the period 1994–2012, immigrants’ wage growth in France outperformed that of natives. We investigate to what extent changes in task‐specific returns to skills contributed to this wage dynamics differential through two channels: changes in the valuation of skills (price effect) and occupational sorting (quantity effect). We find that the wage growth premium of immigrants is mainly explained by the progressive reallocation of immigrants toward tasks whose returns increase over time. Immigrants seem to have taken advantage of labor demand restructuring driven by globalization and technological changes.  相似文献

Manufacturers in many industries seek service-led growth beyond their product core. Yet research on the link between service revenue growth and firm profitability is still at an early stage. To shed further light on this complex relationship, we report the results of a longitudinal study based on panel data of 414 companies in the German mechanical engineering industry collected over a five-year period. Employing latent growth curve modeling and using multiple group analysis, the study provides empirical evidence for the causality between service infusion strategies and manufacturers' profit trajectories. The results also reveal differential effects of service categories and the moderating role of manufacturers' product innovation efforts. For companies with high product innovation activity, services supporting the product (SSPs) directly increase firm profitability, while services supporting the clients' actions (SSCs) do not display any link with long-term profitability. Conversely, for companies with low product innovation activity, SSCs have a significant, positive effect on firm profitability, while SSPs have only an indirect effect. In sum, our findings caution managers that service offerings do not automatically improve company profits. Manufacturers must carefully consider the fit between their service offerings and product innovation activities to grow bottom line results.  相似文献

In this paper, we present the results of a Learning-to-Forecast Experiment (LtFE) where we eliciting short- as well as long-run expectations regarding the future price dynamics in markets with positive and negative expectations feedback. Comparing our results on short-run expectations with the LtFE literature, we prove that eliciting long-run expectations has no impact on the price dynamics nor on short-run expectations formation. In particular, we confirm that the Rational Expectation Equilibrium (REE) is a good benchmark only for the markets with negative feedback. Interestingly, our data show that while the term structure of the cross-sectional dispersion of expectations is convex in positive feedback markets, it is concave in negative feedback markets. Differences in the slope of the term structure stem from diverse degrees of uncertainty regarding the evolution of prices in the two feedback systems: (1) in the negative feedback system, the convergence of the price to the REE reflects a tendency for coordination of long-run expectations around the fundamental value; (2) conversely, oscillatory price dynamics observed in the positive feedback system is responsible for the diverging pattern of long-run expectations. Finally, we propose a new measure of heterogeneity of expectations based on the scaling of the dispersion of expectations over the forecasting horizon.

Abstract

Recent literature on lesbian, gay, bisexual and transgender (LGBT) expatriates has largely taken an employee perspective. Less attention has been devoted to organizational mechanisms supporting LGBT voice opportunities for global mobility. In this study, we use respondent data from 15 LGBT employees in combination with data from five global mobility managers to examine the role of Employee Resource Groups. Using the depth, scope and level of voice to frame the study in relation to stereotype threat theory, the findings show that discrimination and stigmatization are prevalent features affecting voice. The findings advance three distinct contributions concerning marginalized (LGBT) employee voices about expatriation: the importance of ‘informal’ social dialogue, the shallow ‘depth’ to voice decision-making roles about LGBT expatriation, and a consideration of ‘silence’ in voice literatures.  相似文献

This article examines the validity of the assumption that employees' perceptions of those people management activities of their supervisor that impact on employees' abilities, motivation and opportunities to perform influence employee extra‐role behaviour. The results of a longitudinal survey with data from 3,368 employees provide support for this assumption. This study's distinctive features – the concept of people management that involves the management of HR implementation, the longitudinal research design, and the use of the AMO framework for specifying the linkages between HRM and performance – make it possible to address the core questions in the HRM‐performance debate that still remain unanswered according to Guest.  相似文献

Forecast combination through dimension reduction techniques   总被引:2,自引:0,他引:2  
This paper considers several methods of producing a single forecast from several individual ones. We compare “standard” but hard to beat combination schemes (such as the average of forecasts at each period, or consensus forecast and OLS-based combination schemes) with more sophisticated alternatives that involve dimension reduction techniques. Specifically, we consider principal components, dynamic factor models, partial least squares and sliced inverse regression.Our source of forecasts is the Survey of Professional Forecasters, which provides forecasts for the main US macroeconomic aggregates. The forecasting results show that partial least squares, principal component regression and factor analysis have similar performances (better than the usual benchmark models), but sliced inverse regression shows an extreme behavior (performs either very well or very poorly).  相似文献

This paper examines the ways in which accounting has intervened in the process of reforming the original ‘reform’ of the Italian health care system. By stepping into an ongoing process accounting has been asked not only to foster efficiency, effectiveness and value for money, but to correct as well the ‘degeneration’ of the original reform, which subjected health care delivery to ‘democratic’ scrutiny and political control. The call for a greater accountability in the use of public resources has been thus interpreted as both a mechanism of surveillance and control and a way to resist the ‘over-politicization’ of health sector management together with the abuses, scandals and fraudulent behaviour it induced. In seeking to interpret the specificity of the Italian experience, the paper suggests that the range of ‘the contexts in which accounting operates’ should be broadened in order to gain a deeper understanding of its roles in those institutions, such as health care systems, which play a crucial role in modern societies. In order to move in this direction systematic and empirically grounded cross-national comparisons are called for, since, although accounting and management are involved in virtually all attempts to redesign health care services, consequences are likely to be different when conditions of possibility differ at the outset.  相似文献

The problems caused by water scarcity demand important changes in the criteria and objectives of water policies. The agricultural sector in Spain consumes up to 80% of all available hydric resources and the need to increase the efficiency of current uses of water in the agricultural sector is at the core of the country's national water policy. One alternative would be to resort to water pricing policies with the aim of providing incentives to save water consumption although it would inflict a certain degree of income losses to the farmers and raise the revenue collected by the water authorities. The objective of this research is to analyze the effect caused by the application of different water pricing policies on water demand, farmers' income and the revenue collected by the government agency. To undertake this analysis a dynamic mathematical programming model has been built that simulates farmers' behavior and their response to different water pricing scenarios. Empirical application of the model has been carried out in several irrigation districts in Spain covering varied farm regions and river basins. Results show that the effects of alternative pricing policies for irrigation water are strongly dependent on regional, structural and institutional conditions and that changing policies produce distinct consequences within the same region and water district. Thus, equivalent water charges would create widespread effects on water savings, farm income and collected government revenue across regions and districts.  相似文献
