Abstract

Purpose

Selecting and scheduling optimal project portfolio simultaneously is a complex decision-making problem faced by organizations to realize the strategy. However, dynamic synergy relationships among projects complicate this problem. This study aims at constructing a project portfolio selection and scheduling (PPSS) model while quantifying the dynamic synergetic effects to provide decision support for managing PPSS problems.

Design/methodology/approach

This study develops a mathematical model for PPSS with the objective of maximal project portfolio benefits (PPBs). To make the results align with the strategy, comprehensive PPBs are divided into financial and non-financial aspects based on the balanced scorecard. Then, synergy benefits evolve dynamically in the time horizon, and system dynamics is employed to quantify them. Lastly, a case example is conducted to verify the applicability of the proposed model.

Findings

The proposed model is an applicable model for PPSS while incorporating dynamic synergy. It can help project managers obtain the results that which project should be selected and when it should start while achieving optimal PPBs.

Originality/value

This study complements prior PPSS research in two aspects. First, financial and non-financial PPBs are designed as new criteria for PPSS, making the results follow the strategy. Second, this study illuminates the dynamic characteristic of synergy and quantifies the synergetic effect. The proposed model provides insights into managing a PPSS effectively.

Abstract

The European Union’s Digital Markets Act (DMA) calls for far-reaching changes to the way economic activity will occur in EU digital markets. Before its remedies are imposed, it is critical to assess their impacts on individual markets, the digital sector, and the overall European economy. The European Commission (EC) released an Impact Assessment in support of the DMA that purports to evaluate it using cost/benefit analysis.

An economic evaluation of the DMA should consider its full impacts on dynamic competition. The Impact Assessment neither assesses the DMA's impact on dynamic competition in the digital economy nor evaluates the impacts of specific DMA prohibitions and obligations. Instead, it considers benefits in general and largely ignores costs. We study its benefit assessments and find they are based on highly inappropriate methodologies and assumptions. A cost/benefit study using inappropriate methodologies and largely ignoring costs cannot provide a sound policy assessment.

Instead of promoting dynamic competition between platforms, the DMA will likely reinforce existing market structures, ossify market boundaries, and stunt European innovation. The DMA is likely to chill R&D by encouraging free riding on the investments of others, which discourages making those investments. Avoiding harm to innovation is critical because innovation delivers large, positive spillover benefits, driving increases in productivity, employment, wages, and prosperity.

The DMA prioritizes static over dynamic competition, with the potential to harm the European economy. Given this, the Impact Assessment does not demonstrate that the DMA will be beneficial overall, and its implementation must be carefully tailored to alleviate or lessen its potential to harm Europe’s economic performance.

Abstract

The emphasis on inter-organizational systems gave rise to concerns about inter-organizational relationships as trading partners became aware of the socio-political factors and trust that affect their relationships. This paper examines the importance of inter-organizational-trust in business-to-business E-commerce organizations. It examines how inter-organizational relationships impact trading partner trust, perceived benefits, perceived risks, and technology trust mechanisms in E-commerce that can in turn influence outcomes of business-to-business E-commerce. This paper develops a conceptual model and tests the model using a case study research methodology. The aim is to solicit qualitative in depth understanding of inter-organizational-trust in business-to-business E-commerce. Eight organizations from a cross section of industries that formed four bi-directional dyads participated in the third stage of this study. The first two stages include exploratory case studies in three organizations in the automotive industry that applied EDI via Value-Added-Networks in 1997, and a nationwide survey of organizations that examined the extent of E-commerce adoption in Australia and New Zealand in 1998. The findings identify the need for trustworthy business relationships in an E-commerce environment.

Abstract

This chapter outlines the nascent history of the Benefit Movement, discusses the theoretical implications that predict the long-term success of movement goals, and provides recommendations for firms who seek to safeguard practices of corporate social responsibility (CSR). The chapter provides an overview of Benefit forms and describes the indicators of Movement success. For the Benefit Movement to achieve success, it must establish legal options in all 50 states for Benefit incorporation, pave the way for both publicly and privately held organizations to incorporate, and mobilize diverse organizational actors with high levels of commitment to sustain contention for Movement goals. The chapter provides a framework to understand how the Movement can achieve its goal of safeguarding the effective practice of CSR within firms and across the planet.

Abstract

Citizens are substantial stakeholders in every e-government system, thus their willingness to use and ability to access the system are critical. Unequal access and information and communication technology usage, which is known as digital divide, however has been identified as one of the major obstacles to the implementation of e-government system. As digital divide inhibits citizen’s acceptance to e-government, it should be overcome despite the lack of deep theoretical understanding on this issue. This research aimed to investigate the digital divide and its direct impact on e-government system success of local governments in Indonesia as well as indirect impact through the mediation role of trust. In order to get a comprehensive understanding of digital divide, this study introduced a new type of digital divide, the innovativeness divide.

The research problems were approached by applying two-stage sequential mixed method research approach comprising of both qualitative and quantitative studies. In the first phase, an initial research model was proposed based on a literature review. Semi-structured interview with 12 users of e-government systems was then conducted to explore and enhance this initial research model. Data collected in this phase were analyzed with a two-stage content analysis approach and the initial model was then amended based on the findings. As a result, a comprehensive research model with 16 hypotheses was proposed for examination in the second phase.

In the second phase, quantitative method was applied. A questionnaire was developed based on findings in the first phase. A pilot study was conducted to refine the questionnaire, which was then distributed in a national survey resulting in 237 useable responses. Data collected in this phase were analyzed using Partial Least Square based Structural Equation Modeling.

The results of quantitative analysis confirmed 13 hypotheses. All direct influences of the variables of digital divide on e-government system success were supported. The mediating effects of trust in e-government in the relationship between capability divide and e-government system success as well as in the relationship between innovativeness divide and e-government system success were supported, but was rejected in the relationship between access divide and e-government system success. Furthermore, the results supported the moderating effects of demographic variables of age, residential place, and education.

This research has both theoretical and practical contributions. The study contributes to the developments of literature on digital divide and e-government by providing a more comprehensive framework, and also to the implementation of e-government by local governments and the improvement of e-government Readiness Index of Indonesia.

Abstract

The perception of costs and benefits allows residents to carry out an assessment that determines their attitude towards tourism. This study seeks to determine the effect of the perceived benefits and costs (economic, sociocultural and environmental) on the support to the arrival of more tourists, both directly and mediated by overall attitude towards tourism, in the case of Punta del Este. Punta del Este forms part of the Department of Maldonado and is the main sun and beach tourism destination in the Oriental Republic of Uruguay. The questionnaire contained items with five-point Likert scales and sociodemographic questions. The data used (obtained between March and August 2016) are made up of a sample of 420 residents from Maldonado and Punta del Este. The analysis of the data has been carried out through partial least squares (PLS) regression, specifically SmartPLS. Among the results, it should be noted that benefits and costs perceived have no direct effect on the support to the arrival of more tourists; only economic benefits (positive) and sociocultural costs (negative) have a significant effect on the overall attitude towards tourism; the support to the arrival of more tourists depends exclusively on the overall attitude.

Abstract

Purpose

This chapter examines collaboration among highly autonomous, powerful, professional peers to explain why the benefits of teamwork that scholars typically find in traditional teams may not apply. The chapter analyzes the perspectives of individual professionals to show that, in this setting, collaboration is often seen as more costly than rewarding for the individuals involved. It presents a conceptual framework exploring this paradox and suggests directions for future research to elaborate an underlying theory.

Methodology/approach

The chapter draws on extensive qualitative data from surveys and interviews in three professional service firms, including a top 100 global law firm, a boutique executive search firm, and a large, US-based commercial advisory firm. Findings are married integrated with organizational theory to develop testable propositions for future research.

Findings

Because senior professionals collaborate with peers who have the autonomy to choose to work collectively or independently, power and authority are not means to create a team or make it effective. Findings show how professionals interpret the relative costs and benefits of collaboration, and suggest that in most cases, senior professionals will not attempt it or give it up before collaborations can reap important benefits. Thus, short-term costs prevent opportunities to experience longer term benefits for many professionals. Yet, some professionals have figured out how to use “instrumental collaboration” to shift the balance in their favor. The chapter’s conceptual framework uses a longitudinal perspective to resolve this seeming paradox.

Research implications

The chapter presents a nascent theory of instrumental collaboration, including five testable hypotheses, an emergent conceptual framework, and suggestions for specific future research directions.

Abstract

As unemployment rises across the European Union (EU), it is important to understand the extent to which the incomes of the new unemployed are protected by tax–benefit systems and to assess the cost pressures on the social protection systems of this increase in unemployment. This chapter uses the EU tax–benefit model EUROMOD to explore these issues, comparing effects in five EU countries. It provides evidence on the differing degrees of resilience of the household incomes of the newly unemployed due to the variations in the protection offered by the tax–benefit systems, according to whether unemployment benefit is payable, the household situation of the unemployed person and across countries.
