The hypothesis of non-satiation of rational choice theory is very seldom posed under scrutiny, maybe because it is taken as an anthropologic reality. Looking closer to that, we discover that it is taken for granted only in economic theory, and that it has become a reality as a result of a...

A subjective well-being approach is followed to assess the magnitude of inefficiency in the use of income. The information comes from a Mexican survey and an X-inefficiency technique is used. The paper shows that there exists substantial inefficiency in the use of income at all income levels,...

Poverty measures in developing countries often ignore the distribution of resources within families and the gains from joint consumption. In this paper, we extend the collective model of household consumption to recover mother's, father's and children's shares together with economies of scale,...

This paper is a first attempt to provide a quantitative evaluation of consumer well-being resulting from the UK Soft Drinks Industry Levy introduced in April 2018. Using a model setup that encompasses both a normal case and a Giffen case for sugary drinks consumption, a computational exercise is...

Welfare analyses conducted by policy practitioners around the world usually rely on equivalized or per-capita expenditures and ignore the extent of within-household inequality. Recent advances in the estimation of collective models suggest ways to retrieve the complete sharing process within...

Neoclassical economic theory rules out systematic errors in consumptionchoice. According to the basic view, individuals know what they choose. They areable to predict how much utility an activity or a good produces for them now and inthe future and they can maximize their utility. This implies...

We propose a new methodology to estimate the share of household income accruing to children (i.e., the cost of children). Following the principle of the Rothbarth approach, the identification of the children's share requires the observation of at least one adult-specific good. However, our...

We apply an extension of the Rothbarth approach to estimate the share of household resources accruing to children (i.e., the cost of children) in Ireland. The method also allows us to identify the economies of scale in the household and indifference scales in Lewbel (2003)’s sense. A practical...

In this paper, a formalization of Martin Seligman's concept of full life is presented by employing basic microeconomics. With the formalized version of the concept, it can be explained why people differ with respect to the levels of pleasant, engaged and meaningful life they are trying to...

In this paper, we attempt to show why the importance of relational goods compared to conventional goods and status goods threatens to decline in contemporary societies. In our point of view, the development of the relative significance of these three types of goods is not a consequence of...
