This paper aims to identify the impacts of sociodemographic covariates on behavioural biases (BB) scores; the psychometric evidence of the BB measurement instruments; and the main BB that influences the decision-making of individual investors.

Papers were retrieved through search using keywords in ten databases. This systematic review is based on 69 peer-reviewed papers, most of which were published between 2017 and 2021. The relevance of the included papers was assessed through the analysis of statistical/psychometric methods used, and content analysis of the BB literature and its sociodemographic correlations.

Overconfidence is higher in men and not related to age. There was no consensus regarding the relationship between BB and other sociodemographic variables. Most measuring instruments are ad hoc, showing ≤ 4 types of psychometric evidence and assessing ≤ 9 BB. Therefore, the findings demonstrate that there is no gold standard instrument for measuring investors’ BB. Furthermore, 37 BB were cited as influencers of individual investors’ decision-making and overconfidence, herding, anchoring, representativeness and loss aversion were the most prevalent.

Considering that very few systematic reviews have been published in the behavioural finance area, this paper highlights the current state-of-the-art and identifies significant gaps in the literature that can be explored by further research.

To the best of the authors’ knowledge, this is the first systematic review that analyses the psychometric properties of instruments used for individual investors BB assessment.

The purpose of this is to propose a model in which materialism is a mediator of the effects of self-esteem, impulsiveness, attitude toward debt, attitude toward credit card and economic vulnerability on consumer indebtedness. The effects of financial knowledge, financial ability, credit card use and demographic variables are also taken into account.

Survey data from a sample of 1,245 low-income consumers from Brazil were used to test the hypotheses using structural equation modeling.

First, materialism has a significant effect on consumer indebtedness; at the same time, it is influenced by self-esteem, impulsiveness and attitude toward debt. Second, materialism acts as a mediator, e.g. higher impulsiveness triggers materialism, which influences debt level. Third, indebtedness is higher for women and those who use a higher number of credit cards and are more educated.

Financial education programs should work to increase individual’s perceived ability to manage money, as the individuals who feel less able to manage their personal finances alone (i.e. lower financial ability) presented higher indebtedness.

This study investigates consumer indebtedness by addressing factors that have been analyzed independently in the literature. The research combines psychological, financial and economic factors with credit card use and demographic variables to explain consumer indebtedness. Moreover, the study supports the mediating role of materialism for the antecedents of consumer indebtedness, e.g. impulsiveness and attitude toward debt.

The purpose of this paper is to determine the antecedents and consequences of financial literacy by using meta-analytic techniques.

The authors conducted a meta-analysis of 44 valid studies, which generated a total of 690 observations (effect sizes).

The findings showed that the factors influencing financial literacy were as follows: educational level, financial attitude, financial knowledge, financial behaviour, gender, household income and investments. The consequences of financial literacy were the behaviour of incurring avoidable credit and checking fees, credit score, and the willingness to take investment risks. The authors also find some methodological, cultural, economic and theoretical moderations effects between financial literacy and antecedent/consequent constructs.

This meta-analysis reviewed the relationships found worldwide in the literature on financial literacy. The authors also identified new avenues for future research. Some specific limitations, such as the non-use of qualitative studies, are registered.

This research tested the impact of the antecedents, consequences and moderators of financial literacy via a meta-analytical review. This meta-analysis contributes to the marketing and financial literature by offering a set of empirical generalisations about the direct and moderation effects investigated.
