Portfolio management using a factor-analytic stock selection strategy

This study takes an integrated look at six widely documented price-related CAPM anomaly variables. Using maximum likelihood factor analysis, we extract factors common to these variables. We find that portfolios formed according to the first extracted factor alone exhibit abnormal performance. Further, the performance of firms ranked on the basis of extracted factor scores for this factor is superior to that of firms selected on the basis of any one of the six variables. Our results have implications for (1) isolating missing factors in the CAPM specification and (2) designing dynamic portfolio strategies aimed at jointly exploiting more than one anomaly.     

Towards a resilience management framework for complex enterprise systems upgrade implementation

The lack of knowledge of how resilience management supports enterprise system (ES) projects accounts for the failure of firms to leverage their investments in costly ES implementations. Using a structured-pragmatic-situational (SPS) case study research approach, this paper reports on an investigation into the resilience management of a large utility company as it implemented an ES upgrade. Drawing on the literature and on the case study findings, we developed a process-based resilience management framework that involves three strategies (developing situation awareness, demystifying threats, and executing restoration plans) and four organisational capabilities that transform resilience management concepts into practices. We identified the crucial phases of ES upgrade implementation and developed indicators for how different strategies and capabilities of resilience management can assist managers at different stages of an ES upgrade. This research advances the state of existing knowledge by providing specific and verifiable propositions for attaining a state of resilience, the knowledge being grounded in the empirical reality of a case study. Moreover, the framework offers ES practitioners a roadmap to better identify appropriate responses and levels of preparedness.     

A change management perspective on public sector cutback management: towards a framework for analysis

The financial crisis forces public managers to implement cutbacks within their organization. We argue that adopting a change management perspective contributes to our understanding of cutback management by adding a focus on managerial behaviour regarding cutback-related organizational changes. Relying on change management literature, this paper develops a framework for the analysis of cutback management connecting the context, content, process, outcomes and leadership of cutback-related change. From this it follows that managers can be positioned at the intersection of various imperatives, both externally and internally, such as their political leaders and their own subordinates. A research agenda is proposed.     

Coopetitive games for environmental sustainability: Climate change and decision global policies

In this work, we propose and analyze a coopetitive model for the Climate Change environmental sustainability: a global duopoly type game structure, involving a generic type of green technological good. Our model allows to select certain strategy profile solutions within a continuous horizon of possible global scenarios, in the context of the Paris agreement COP21 and after Trump’s decision to abandon the agreement itself. More specifically, we construct a parametric coopetitive game with two great actors, US and the group of countries which still agree to COP21. The two actors of our duopoly game compete on the global market by producing and selling green technological goods (for example: electric cars, electric airplanes, hydrogen cars, solar panels, low impact batteries for smart houses, electric cars or self phones, and so on). Our multi-dimensional coopetitive model suggests possible cooperative strategies in order to improve the efficiency and strength of the actions enforced by the countries to mitigate the Climate Change catastrophic risk at the level of its causes and effects.     

Cloud-based smart asset management for urban flood control

Urban flooding, frequently occurring in metropolitan areas, is one of the largest disasters worldwide. Albeit a large number of approaches and Enterprise Information Systems (EISs) have been designed for urban flood control, the ineffective management of physical assets has greatly impeded their deployment. Managing diverse physical assets is critical in urban flood control. Challenges exist in sharing assets and services between agencies, and ensuring real-time and flexible decision supports. This paper proposes a cloud-based asset management platform. Cloud technology is adopted for processing the huge amount of data collected by various physical assets and for providing flexible access interfaces. Service-oriented methods are applied to facilitate the sharing of assets and services and to enable the development of flexible and scalable Decision Support Systems (DSSs). Moreover, the concept of smart asset is introduced for remote real-time data collection, and the corresponding software agent model is developed to wrap these diverse assets, realising the UPnP (Universal Plug and Play) working mode. Finally, a case study on the urban flood control process of Guangqumen Bridge in Beijing is provided to illustrate the asset management processes of the proposed platform.     

Climate change mitigation: Carbon assurance and reporting integrity

Concern about climate change has increased the pressure on firms to be accountable for social impact and to report on environmental, social and governance (ESG) performance. Focusing on the view that sustainability-oriented firms are likely to consider wider stakeholder interests and pursue high financial reporting integrity, this paper examines the association between carbon assurance and earnings management. Using a sample of firms listed on the New York Stock Exchange, we find voluntary adoption of carbon assurance (level), carbon disclosure and gender diverse boards are negatively associated with earnings management. Additional tests using different components of carbon assurance (percent and verification) confirm our main results. Our results suggest that firms that voluntarily invest in carbon assurance, carbon disclosure and gender diverse boards are less likely to engage in earnings management and thus have higher reporting integrity. This aligns with the view that firms' ethical concerns translate into higher quality reporting.     

Demographic change and implications for planning economic strategy

The growth of population and jobs in nonmetropolitan areas and the decline in growth of metropolitan areas during the previous decade represented a significant reversal in previous settlement patterns in the industrial world. This paper examines the importance of economic and demographic change in explaining recent spatial patterns of concentration and deconcentration within a system's framework, and suggests implications for strategic economic and planning policies. The central hypothesis of this paper is that the nature of these interrelationships determine in large part the dynamics of change within metropolitan and nonmetropolitan areas and makes possible a comprehensive view of the implications, for spatial redistribution, of planning policies and strategies.     

Intraday portfolio risk management using VaR and CVaR:A CGARCH-EVT-Copula approach

The study forecast intraday portfolio VaR and CVaR using high frequency data of three pairs of stock price indices taken from three different markets. For each pair we specify both the marginal models for the individual return series and a joint model for the dependence between the paired series. We have used CGARCH-EVT-Copula model, and compared its forecasting performance with three other competing models. Backtesting evidence shows that the CGARCH-EVT-Copula type model performs relatively better than other models. Once the best performing model is identified for each pair, we develop an optimal portfolio selection model for each market, separately.     

Climate for conflict management,exposure to workplace bullying and work engagement: a moderated mediation analysis

The present study investigates a potential preventive factor in relation to workplace bullying. Specifically, we examine how climate for conflict management (CCM) may be related to less bullying, increased work engagement, as well as whether CCM is a moderator in the bullying engagement relationship. The study was based on a cross-sectional survey among employees in a transport company (N = 312). Hypotheses were tested simultaneously in a moderated mediation analysis which showed that bullying and job engagement were related (H1), CCM was related to less reports of bullying (H2), CCM was related to work engagement (H3) and that CCM was indirectly related to job engagement through bullying (H4), but only when CCM was weak (H5). That is, CCM moderated the relationship between bullying and work engagement in that this relationship only existed when CCM was low. The present study contributes to theory within this research field by showing that organizational measures may not only prevent bullying, but may also affect how employees react when subjected to bullying. Furthermore, the effect of climate in relation to bullying may be down to the narrow bandwidth facet of CCM. The study informs employers how they may act to prevent bullying while also reducing the potential negative outcomes of those cases of bullying that inevitably will show up from time to time.     

Guest Editorial: A purchasing and supply management view of supply resilience for better crisis response

Purchasing and supply management (PSM) has been under great pressure since the COVID-19 pandemic first shook the world. Companies and public organizations faced new kinds of supply disruptions, and at a scale never seen before. New response abilities were required from PSM to address these challenges and disruptions. This Editorial introduces four articles in the Special Issue on “PSM learning from the pandemic: transforming for better crisis management.” These empirical contributions show how companies could build resilience to survive and be competitive during the COVID-19 pandemic. This Editorial discusses how supply resilience should be conceptualized in post-pandemic supply chains adopting a PSM perspective. We suggest that supply resilience practices should be developed and planned according to whether they strengthen existing supply chain relationships (bridging) or establish new ones (buffering) and whether they are short-term (temporary) or long-term (permanent) orientated. Furthermore, three supply resilience capabilities, absorbing, responding and capitalizing, should be prioritized in supply chains for responding to and recovering from global crises and disruptions. Supply resilience is key to crisis response and recovery, and PSM has an essential role in building and sustaining that resilience.

Dynamic change of corporate environmental strategy: rhetoric and reality

Although rhetoric involves political and symbolic posture, and does not always accurately represent reality, it plays an important role in the dynamic change process of environmental strategy. We first elaborate on the related concepts and develop frameworks to analyze corporate environmental strategy and its change. We report two case studies of Korean companies using the framework. Longitudinal case studies also provide additional implications for corporate environmental strategy in developing countries such as Korea. There is a gap between the rhetoric and reality of environmental strategy and it constantly changes over time depending on specific internal and external influences. The strength of external influences is a factor that determines whether the change is real or merely rhetorical. Internal organizational variables most likely affect the reality of environmental strategy. We show that the elaboration of rhetorical and realistic aspects of corporate environmentalism can bring out deeper insights and new theoretical developments.
