We find that difference aversion decreases while social-welfare preferences increase with age.
In Arneson's (1989, 1990) concept of equal opportunity for welfare, the preferences determining the measure of individual well-being are meant to be conceived hypothetically — i.e., a person would decide on them after a process of ideal reflection.
If one contentiously identifies subjective welfare with preference satisfaction, it seems implausible to count all individual preferences as equal, some — such as the desire to do others wrong — being inadmissible on grounds of justice (the offensive taste argument).
Other possible metrics are needs, basic needs, or the many different types of subjective welfare or preference satisfaction.
Because the identification of welfare with preference satisfaction makes it questionable whether one can make interpersonal welfare comparisons, few economists defend a utilitarian view of policy as maximizing total or average welfare.
Since 2000, I've published more than 120 articles in peer reviewed scientific journals on a wide range of topics ranging from the economics of animal welfare to consumer preferences for genetically modified food to the impacts of new technologies and policies on livestock and meat markets to analyzing the merits of new survey and experimental approaches eliciting consumer preferences.
