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 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...

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;...

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 utilizes panel data from rural India on a daily rated labour market to examine how workers deal with the uncertainty which arises from the existence of involuntary unemployment. In particular, it measures the relative explanatory power of the three models which the literature suggests...

When adopted by each member in a society contracts become conventions: they are focal points that solve coordination problems. This paper develops an evolutionary model with two distinct finite populations of players (landlords and landless) in which players from different populations are...

This paper developes an evolutionary model to discus the issue of efficiency in non-profit organisations. The ideological commitment that characterizes most of them is depicted through the introduction of a role for moral and social norms. It comes out that attracting motivated employees can be...

This paper identifies in a feed-forward neural network the mathematical algorithm which can catch the learning process highlighted by econometric works that makes people assess the satisfaction arising in each single contingency so that they are better depicted in their decision making by an...

This paper suggests an evolutionary model to account for the bargaining process in transitional economies leading to the emergence of formal and informal agreements between landowners who for whatever reason are not willing to farm and landless who are willing to cultivate land. In particular,...

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...
