Design Evaluation of the Universalization Fund for Telecommunication Services in Brazil

Article January 23, 2026

The Universalization Fund for Telecommunications Services (Fust) was designed in 2000 to provide public investments to expand services in areas that needed to be better covered by the telecom carries. However, since its creation, the fund lacks effectiveness. The study seeks to evaluate this public policy and explain the practically non-existent results and impacts until now. Our contribution is to structure this public policy using a logic model and the program theory of change to understand and evaluate the fund’s regulatory design. The analysis recognizes that the recent changes in Fust’s legislation have improved its architecture and governance, following suggestions from the international literature on universalization funds. Nonetheless, some additional regulatory adjustments are suggested, such as creating more restrictive mechanisms to block or reallocate the fund’s revenues, keeping its steering committee active, discussing new sources of revenue, and improving communication and transparency.

Subordinated Financial Notes: An Analysis of the Factors That Explain Their Price

Article January 23, 2026

A Letra Financeira Subordinada (LFS) é um tipo de instrumento que possibilita a captação com efeito na composição de capital do banco. O investimento nesse papel é considerado de alto risco para o investidor, pois existe a possibilidade de perda do rendimento em caso da não geração de lucro do banco emissor e perda do valor principal em caso de falência. Para compreender as características da LFS foram analisadas a legislação e as normas que tratam sobre o instrumento financeiro. Posteriormente estimou-se o valor de negociação de LFS no mercado secundário a partir de variáveis econômicas e de crédito, através de regressão linear múltipla. A análise de correlação demonstrou que as variáveis de valor da LFS estão mais correlacionadas com as variáveis de crédito do que com as variáveis econômicas. O resultado da regressão principal mostrou que o estoque das carteiras de crédito do banco e o nível do PIB possuem o maior poder explicativo sobre o preço dos LFS.

Credit Card Interest Rate Regulation in Brazil Behavioral Biases Present in the Market and Possible Impacts

Article January 23, 2026

O presente estudo analisa as implicações econômicas e comportamentais associadas à regulação das taxas de juros no mercado de cartões de crédito no Brasil, com foco na recente regulamentação que estabeleceu limites para juros e encargos financeiros em operações de crédito rotativo e parcelado. A pesquisa contextualiza a importância dos cartões de crédito como meio de pagamento, destacando o impacto das altas taxas de juros e inadimplência no sistema financeiro. A análise abrange fatores estruturais, como o custo do crédito e os vieses comportamentais que influenciam as decisões dos consumidores e empresas, discutindo os possíveis efeitos da regulação, incluindo mudanças nas estratégias dos emissores, redução da oferta de crédito e o papel do parcelamento sem juros no consumo. O trabalho também propõe reflexões sobre educação financeira e incentivos ao uso consciente do crédito como ferramentas para uma inclusão financeira mais sustentável.

Understanding Mobile Internet Access and Data Plan Choice in Brazil: A Machine Learning Approach

Article January 23, 2026

This paper applies the Elastic Net Machine Learning technique to choose the variables that best represent the characteristics of mobile internet use in Brazil. We use regularized models to estimate the importance of a large number of variables, including socioeconomic attributes, internet and device utilization patterns, and digital skills to explain (a) access to the internet through mobile devices and (b) choice of mobile data plan. After identifying the most important variables, we estimate their marginal effects on the two dependent variables with nonlinear econometric models. The results suggest that socioeconomic characteristics and user skills have significant explanatory power in both estimations. Specifically, barriers such as age, income, and skill gaps persist, hindering inclusive mobile internet adoption. Conditional on mobile internet use, these characteristics are more common among postpaid internet data plan subscribers. Moreover, communication skills like messaging and social media use stand out regarding internet access, whereas internet utilization patterns (on the move and at work) have high explanatory power in the data plan choice.
