Behavioral biases and personal indebtedness: a systematic literature review

Abstract

Objective The level of indebtedness of individuals has increased significantly in recent decades. The objective of this study was to analyze the scientific literature that evaluates the interrelationships between behavioral biases and personal indebtedness, with a view to investigating the intellectual structure of publications on the influence of behavioral biases on the level of personal indebtedness. Methodology Bibliometric analysis of scientific publications carried out until October 2023 in the "Web of Science" and "Scopus" databases and which analyze determinants of personal indebtedness from the perspective of behavioral sciences was used. Results The results reveal works with global and local relevance, how indebtedness has been discussed from a behavioral perspective and the main cognitive biases associated with it, research clusters that can serve as a reference for researchers, trends and research gaps in this field of knowledge, and that combining constructs from the field of behavioral sciences with other areas of knowledge, especially education/knowledge and psychology/behavior, tends to expand the literature related to personal indebtedness. Originality Based on the content analysis of the articles, an innovative scheme illustrating the possible definitions of indebtedness from an economic and psychological perspective is presented, which is an important contribution to the literature.

Inflation: an analysis between the variation of the Basic Food Basket value and the regional Purchasing Power

“…Only in the last ve years (2018-2021), practically all Brazilian capitals showed an increase in the value of the Basic Food Basket, indicating signs of rising in ation indices (Dieese, 2023).

In this scenario, price dispersion across all markets incentivizes price research (Najberg, 1994).…”
