In a spatial competition model, changes in firms' competitive behaviour may occur when the hypothesis that individual gross surplus is positive in equilibrium is relaxed. We prove that there exists a region of the relevant parameter where firms' behaviour mimics collusion, while in another range...

In this paper, I develop an operational methodology to consistently compare alternative sustainability paradigms (weak sustainability [WS], strong sustainability [SS], a-growth [AG], and de-growth [DG]) and different assessment approaches (life-cycle assessment [LCA], cost-benefit analysis...

This paper presents an analytical model of the dynamic interrelationships between education, creativity, and happiness based on both theoretical insights and recent empirical neurological studies. In the model, the outcome is conditional on individual intelligence and risk aversion....

This paper presents the first empirical test of coherence (i.e., consistency of policies within a framework), efficiency (i.e., ability of policies to meet their objectives), and independence (i.e., logical priority of objectives over policies) of the overall EU environmental policy system. To...

This paper identifies the globally stable conditions under which an individual facing the same choice in many subsequent times learns to behave as prescribed by the expected-utility model. To do so, the analysis moves from the relevant behavioural models suggested by psychology (i.e., weighted...

This paper describes a dynamic system for the interrelationships between happiness and health that considers three main attitudes to life: α, β, and γ for Aristotelian, Epicurean, and Stoic, respectively. All variables that have been shown by empirical and theoretical studies to affect...

This paper develops a theoretical framework to assess the feasibility of global environmental sustainability solutions based on one or more value changes. The framework represents four sustainability paradigms (weak sustainability WS, a-growth AG, de-growth DG, strong sustainability SS) and five...

This paper develops a theoretical framework for four sustainability paradigms (weak sustainability, a-growth, de-growth, strong sustainability) within cooperative and non-cooperative scenarios, and includes changes in four values (a sense of responsibility to nature and future generations;...

In this study, I developed operational versions of Hirsch's H index that can be applied to each researcher's curriculum vitae (CV) to allow cross-disciplinary comparisons. The revised indices account for anomalies that potentially arise from tactical or opportunistic citation and publication...
