Economic Theory and Subjective Well-being: Mexico

Abstract

Several studies have been conducted on the topic of well-being. Most of them, however, have been done in industrialized countries where income is distributed relatively more equitatively and the population tends to be more homogeneous. This paper studies the relationship between subjective and economic well-being in Mexico, a country where the economic differences among the population are more clearly marked.

According to the economic definition of well-being, higher levels of income are associated with higher levels of well-being through greater levels of material consumption. Taking into consideration this definition, it is worth asking just how important income is for an individual's happiness?Existing studies in psychology have found a positive correlation between economic well-being (socioeconomic status) and subjective well-being (happiness). However, this positive relationship is weak and a large percentage of human happiness remains unexplained.

Although the mentioned studies make a good approximation of the existing relationship between income and happiness, the characteristics or specification of the function that generates the relationship between these two variables is often assumed to be linear and positive. The main objective of this paper is to investigate further the relationship between subjective and economic well-being. In this study different specifications and approaches are used to approximate the relationship between these variables.

An empirical analysis is made from the results of a survey conducted in two Mexican cities. The investigation studies the impact of demographic, social, and economic variables on subjective well-being in Mexico. Several hypotheses are tested to identify the relationship between household income and individual well-being. It is found that income does not have a strong influence on neither well-being nor on the probability of happiness. However, people tend to overstress the impact that additional income would have on their subjective well-being. This fact could explain the importance that people place on increasing their income level, and it could possibly explain the relative sense of dissatisfaction once a higher income level is achieved.

The relationship between income and the sense of basic need satisfaction is also explored. A main assumption in economic theory suggests the existence of a direct relationship between these variables; however, empirical results show this relationship to be extremely weak. Results indicate that subjective well-being is positively related to the sense of basic need satisfaction but not to income.
