In the last 25 years, a vast empirical literature has seriously chal- lenged many assumptions on which the standard microeconomic approach is based. Inspired by this evidence, behavioural economics suggests that a research program that integrates the economic, psychological and neuro- scientific...

Recent contributions on intertemporal decision-making and self-control have focused on the impact of cognitive constraints on the way people behave over time. In particular there is evidence on the fact that exerting cognitive effort on the job, adhering to some specific behavioral plan and...

We examine the profitability and social efficiency of horizontal mergers in a Cournot oligopoly with decreasing average costs. Assuming the merger allows for a reduction in the total amount of fixed costs, we identify the conditions under which the merger is, respectively, profitable and...

We reexamine the profitability and social efficiency of horizontal mergers in a Cournot oligopoly with decreasing average costs. Assuming the merger allows for efficiency gains in production, we identify the conditions under which the merger is, respectively, profitable and socially desirable....

Some recent economic contributions have studied individual identity in terms of explicit choices and social categories to which a person belongs to. According to Social sychology, identity is also the result of a process in.uenced by self-regulation mechanisms. We model endogenous...

In a model of repeated Cournot competition under complete information, I show how the existence of a fringe of managerial firms affects the stability of a cartel of strict profit-maximizing firms. There always exists a critical dimension of the fringe that makes the cartel unstable, and this...

We identify a class of noncooperative games in continuous strategies which are best-response potential games. We identify the conditions for the existence of a best-response potential function and characterize its construction, describing then the key properties of the equilibrium. The...

We introduce the concept of Hamiltonian potential function for noncooperative open-loop differential games with n players, n controls and n states, and characterise a sufficient condition for its existence. We also identify a class of games admitting a Hamiltonian potential and provide...

The established view on oligopolistic competition with environmental externalities has it that, since firms neglect the external effect, their incentive to invest in R&D for pollution abatement is nil unless they are subject to some form of environmental taxation. We take a dynamic approach to...

We consider the joint effect of profit and Pigouvian taxation in a model of imperfect competition. We show that, when both profit taxation and Pigouvian taxation/subsidy are used, the former is no longer neutral. The two fiscal tools are substitutes, and for any profit taxation rate there exists...
