The article defines measures of individual and household willingness to pay (and to accept) in a general and flexible framework. It completely clarifies the relationship between the household measures and the sum of the individual welfare measures (the aggregate measures) which are in general...

Temkin (1986,1993) sets out a philosophical basis for the analysis of income inequality that provides an important alternative to the mainstream welfarist approach. We show that the Temkin principles can be characterised by a parsimonious axiomatic structure and we use this structure to derive a...

The paper presents an abstract definition of linear inequality concepts leading to linearly invariant inequality measures and characterizes the class of linear concepts completely. Two general methods of deriving ethical measures are proposed. They imply an Atkinson-Kolm-Sen index and a new dual...

The paper presents a concise account of recent results on the axiomatization of various welfare measures. Following the introduction and discussion of some elementary properties that a welfare measure should satisfy valid measures are derived. In particular, the Hisksian equivalent and...

The optimal pricing rule for public enterprises maximizing welfare under a profit constraint is well known. The paper extends the analysis to the case of production externalities and considers price regulation under various forms of environmental regulation which is assumed to be performed by a...

In modeling emissions, the literature has usually specified an explicit emission function, or treated emissions as a production input. We examine the validity of these approaches, taking into account the materials balance principle. We show that a technology can equivalently be described by (i)...

Considering an economy with two goods {a private good and a household good with a variable degree of publicness {and identical individuals, the paper investigates the implications for economies of size of two extreme households' decision rules: (i) the cooperative model, where households...
