Introduction

John Hicks's statement is important in many ways. First, it states that there are many aspects or domains in a person's life; thus, a person's wellbeing is expected to be related to her situation in all these aspects of life. Second, it recognises that economists usually deal with just one aspect of a person's life; hence, it is impossible to understand a person's wellbeing from an economic perspective alone. Third, it also recognises that economics, as a discipline, is an academic construct that studies only one aspect of a person's life. Hicks's comment refers to economics but it could also apply to any other of the social sciences. Fourth, it recognises that every person is in a society; hence, her wellbeing should be understood within her particular context and culture and in her relation to other persons. Consequently, a person is defined as such within her specific context, and there is no room for an out-of-any-context individual. Finally, it calls for an interdisciplinary study of human beings.

This investigation uses a life-satisfaction conception to study wellbeing. The investigation directly asks persons about their satisfaction with their lives, and this information is used as a proxy for a person's wellbeing.
