This study assesses, from a microeconomic theoretical perspective, competition conditions and market power in the Mexican commercial banking market. Our econometric estimations, using time series, indicate a low price elasticity of demand for bank credit, which, in combination with high market shares and according to the Lerner index, indicates that major banks have elevated market power; the profferedvalues of the Lerner index range between (0.11) and (0.68) for the seven leading banks, (0.00) for small banks, and (0.34) for the weighted average of the entire market. On the other hand, the estimated competition indicators confirm the exercise of market power and the lack of a competitive market, during at least the last decade, resulting in a large fraction of unserved economic agents by commercial banks.

Objective: To determine the influence of hygiene and motivation factors as predictors of job satisfaction and the interest in remaining in a manufacturing company in Mexico. Theoretical Framework: The study is based on Herzberg's Two-Factor Theory, which posits that job satisfaction is influenced by two types of factors: hygienic and motivational. Hygienic factors, such as salary, working conditions, and job security, do not generate satisfaction on their own, but their absence causes dissatisfaction. Method: Ex-post-facto, observational, cross-sectional, and explanatory study was conducted using a Structural Equation Model (SEM) with the maximum likelihood method. The Inventory of Motivational and Hygiene Factors was applied to 346 employees Results and Discussion: The findings indicate that hygiene factors have a greater influence on job satisfaction than motivational factors, partially contradicting Herzberg's theory. Research Implications: Companies should prioritize improving hygienic factors, such as job stability and benefits, to increase employee satisfaction and their interest in staying with the organization. Additionally, they should complement these efforts with professional development programs that promote talent retention and enhance productivity. Originality/Value: The study's originality lies in analyzing the relationship between satisfaction and the interest in remaining based on these variables in a manufacturing environment

Amid the backdrop of the COVID-19 pandemic, the living conditions of the population were dramatically altered, with social distancing measures and the looming threat to public health leaving a profound impact on people’s lives. This study aims to assess the influence of COVID-19 on subjective well-being and overall quality of life in Mexico. A structural model with latent variables was used. Data were extracted from the National Self-Reported Well-being Survey (SWLS) from October 2020 and January 2021, featuring a robust sample size of 3615 residents from urban areas in Mexico, all aged 18 and above. Findings revealed that around 38% of the variance in overall life satisfaction in October 2020 and January 2021 could be attributed to Personal well-being (0.231), Personal satisfaction (0.320), Satisfaction with the environment (0.076), and Negative emotional states (−0.116). In comparison, October 2019 to January 2020 saw a lower 20% explained variance, primarily associated with Personal well-being (0.184), Personal satisfaction (0.270), and Satisfaction with the environment (0.052). Reliability assessments, including Cronbach’s Alpha coefficients, Rho_a, and Composite Reliability, all surpassed 0.70 for each subscale. In addition, our study confirmed convergent validity, as the Average Variance Extracted (AVE) consistently exceeded 0.50 across all subscales, while the discriminant coefficient exceeded 0.70.

The objective was to determine the influence of the subscales of Subjective Well-being (BIARE) on overall life satisfaction for the current year, 2023, compared to the previous year, 2022. This was achieved by comparing the states of the Mexican Republic ranked among the top 10 with those among the bottom 10 in the Human Development Index (HDI), using a structural path modeling with latent variables through the Partial Least Squares (PLS) method. The following findings are presented: Positive Emotional Balance had a higher mean score in the states of the Mexican Republic ranked in the top positions of the Human Development Index. Negative Emotional Balance had a higher mean score in the states ranked in the lower positions of the HDI. Eudaimonia showed a higher mean score in the top-ranked states on the HDI list. Personal Satisfaction also exhibited a higher mean score among states in the top HDI rankings. Satisfaction with the Environment had a higher mean score in states ranking in the higher HDI positions. There were no significant differences in general life satisfaction for the current year among Mexican states based on HDI ranking. Likewise, no significant differences were found for overall life satisfaction in the previous year among these states. Only Eudaimonia (0.41383) and Personal Satisfaction (0.2758) significantly and directly influenced general life satisfaction for the current year, explaining approximately 40% of its variance according to the R-Squared value.
