Does ethical differentiation of products affect market behavior? We examined this issue in triopolistic experimental markets where producers set prices. One producer's costs were higher than the others. In two treatments, the additional costs were attributed to compliance with ethical...

Recent research on the dynamics of moral behavior has documented two contrasting phenomena - moral consistency and moral balancing. Moral balancing refers to the phenomenon whereby behaving (un)ethically decreases the likelihood of doing so again at a later time. Moral consistency describes the...

In the homogeneous case of one type of goods or objects, we prove the existence of an additive utility function without assuming transitivity of indifference and independence. The representation reveals a positive factor smaller than 1 that infuences rational choice beyond the utility function...

This paper proposes an exploration of the methodology of utility functions that distinguishes interpretation from representation. While representation univocally assigns numbers to the entities of the domain of utility functions, interpretation relates these entities with empirically observable...

This paper explores the different climate change strategies chosen by three major multinational oil corporations: ExxonMobil, TotalFinaElf and BP Amoco. They are referred to, as the 'fight against emission constraints,' 'wait and see,' and 'proactive' strategies, respectively. The justifications...

From practice to theory, we introduce a state-of-the-art stream of papers that promotes an inclusive and complementary consideration of both analytical methods and ethical values in Operations Research and Management Sciences (OR/MS). We suggest a perspective according to which the consideration...
