This paper formulates a duopoly model in which firms care about relative profits as well as their own profits. Our purpose is to investigate the relationship between the weight of relative performance and R&D expenditure. We find a non-monotone relationship between the weight of relative...

This study investigates the effects of transparency in a sequential moral hazard problem, where a leader and a follower consecutively take an action. The principal chooses whether the organization is transparent or opaque, by which we mean that the action of the leader is observable to the...

This paper aims to consider the meaning of the dismal theorem, as is presented by Professor Martin Weitzman. The theorem states that a standard cost–benefit analysis breaks down if there is a possibility of catastrophes occurring. This result has a significant influence on debates on the...

This unique book develops an operational approach to preference and rationality as the author employs operators over binary relations to capture the concept of rationality. A preference is a basis of individual behavior and social judgment and is mathematically regarded as a binary relation on...

This study investigates the short‐run and long‐run relationships of trade and privatisation policies. In both the short run and the long run, the optimal degree of privatisation is increasing in the import tariff rate. The optimal tariff rate is strictly positive in the short run but can be...

This paper provides an axiological foundation of a class of sufficientarian principles that are based on the individual transformed well-being gains and losses from a threshold level. The ideas underlying these principles have their origins in the literature on population ethics. We characterize...
