Career plateauing reactions: the moderating role of job scope,role ambiguity and participation among Canadian managers

The purpose of this study is to investigate the moderating effect and the interactive effect of job scope, role ambiguity and participation in decision-making on relationships between career plateauing and outcomes. A cross-sectional survey of 3,065 Canadian managers shows that these job characteristics can contribute to limiting the negative consequences associated with career plateauing. Moreover, in accordance with the theory of work–situation fit, some double moderating effects are found. The attitudes and behaviours of plateaued managers are significantly more positive when their job is richer and offers an opportunity to participate in decision-making. However, contrary to evidence in the literature, results show that reactions to career plateauing are more positive for managers who perceive that their job is richer and their role more ambiguous. Implications and directions for future research are discussed.     

Capacity Commitment versus Flexibility

We show how technological flexibility choices and equilibrium configurations (both simultaneous and sequential duopoly) depend on six industry characteristics. Low market volatility combined with intermediate market size favors inflexible technologies; large values of either volatility or size favor flexible technologies; low or intermediate values of both favor the coexistence of flexible and inflexible technologies. The possibility of a flexibility trap exists in industries of low volatility and intermediate size. Entry prevention can sometimes be achieved by inflexible technologies or flexible technologies, depending on the industry characteristics.     

Education Subsidies, Social Security and Growth: The Implications of a Demographic Shock

We develop a three-period overlapping-generations model in which individual decisions about education are the engine of growth. In this setting, we investigate the normative role of education subsidies and old age pensions. Calibrating this model on empirical data, it is shown that the case for positive pension benefits is rather weak on the optimal path. An important part of education subsidies should be financed by lump-sum taxes on retirees. We also examine how these transfers should be adjusted in the presence of a baby boom-baby bust demographic shock. It turns out that an appropriate policy could be to increase education when the baby-boom generation is at work. Labor productivity will then be higher when aging peaks so that the pension bill can be financed without reducing welfare for the baby-bust generations.

Cybersecurity: Stakeholder incentives,externalities, and policy options

Information security breaches are increasingly motivated by fraudulent and criminal motives. Reducing their considerable costs has become a pressing issue. Although cybersecurity has strong public good characteristics, most information security decisions are made by individual stakeholders. Due to the interconnectedness of cyberspace, these decentralized decisions are afflicted with externalities that can result in sub-optimal security levels. Devising effective solutions to this problem is complicated by the global nature of cyberspace, the interdependence of stakeholders, as well as the diversity and heterogeneity of players. The paper develops a framework for studying the co-evolution of the markets for cybercrime and cybersecurity. It examines the incentives of stakeholders to provide for security and their implications for the ICT ecosystem. The findings show that market and non-market relations in the information infrastructure generate many security-enhancing incentives. However, pervasive externalities remain that can only be corrected by voluntary or government-led collective measures.
