Editorial: 58th issue of the Journal of Economics, Finance and Administrative Science

Abstract

We introduce the December edition, our 58th issue, of the Journal of Economics, Finance and Administrative Science (JEFAS). Our journal consistently delivers outstanding publications in English twice a year, all subjected to double-blind peer-review processes.The first paper authored by Garc� ıa Mata (2023) examines the relationship between age and financial stress among Mexican adults, focusing on identifying the age of peak financial stress. Using data from the National Survey on Financial Inclusion 2021, a financial stress indicator is constructed through confirmatory factor analysis and linear regression with a quadratic term. The findings reveal a quadratic relationship, with financial stress peaking at age 56, influenced by factors such as sex, marital status, number of dependents, education and region. These insights are valuable for financial product designers and policymakers aiming to enhance consumer well-being.Next, the paper of V� azquez-L� opez (2024) analyzes the evolution of Latin American productive integration by examining the regional value added in intra-regional exports for Argentina, Brazil, Chile, Colombia, Mexico and Peru from 1995 to 2015. Using OECD's global ICIO input-output tables and the methodological framework by Wang et al. (2018), the study breaks down the value of gross exports by sector and country based on the origin of value added. The findings reveal that regional partners contribute very little to the value added in intra-regional exports, while non-regional countries, especially China, have increased their share. This trend, along with declining domestic value added, suggests a shallow regional integration process.The results of P� erez-Orozco et al. (2024) offer two key contributions to the field of innovation. First, it provides evidence of the mediating role of marketing management in the relationship between online presence and product innovation among SMEs in developing economies. Second, it encourages practitioners to recognize the advantages of incorporating marketing management strategies into online presence tools to develop products more effectively tailored to customer needs.Research conducted by Ngong et al. (2024) reveals a significant connection between financial technology and economic growth. The findings indicate a bidirectional causality between automated teller machines and economic growth, while showing unidirectional causality from economic growth to point-of-sale systems, as well as from internet banking, mobile banking and government effectiveness to economic growth. The negatively significant error-correction term suggests long-term convergence between fintech indicators and economic growth.Following that, Almeida et al. (2024) assess the occurrence of abnormal returns resulting from stock splits or reverse stock splits within the Brazilian capital market. Utilizing the JEFAS 29,58 206
