Diversification and Performance in Credit Unions: A Non-Linear Approach

Abstract

This study verified the existence of a non-linear relationship between diversification and the performance of Brazilian credit unions by analyzing panel data from 455 credit unions from June 2012 to December 2019. Through three regression models, estimated by the Systemic Generalized Method of Moments, it was identified that diversification has a non-linear U-shaped relationship with performance. This result demonstrates the existence of a minimum point for diversification, from which increases in diversification of financial products would provide positive effects on performance. This study stands out for bringing a curvilinear model for diversification in credit unions. This finding facilitates the understanding of which level of diversification is beneficial for the performance of credit unions, in addition to favoring the formation of strategies and analysis of the implementation of new financial products in credit unions.
