The integration of mathematical tools in economic and business analyses constitutes a vital component of higher education curricula in these disciplines. Previous research has investigated the influence of mathematical proficiency on students'academic performance, particularly in relation to their pre-university educational background. This article builds on that body of work by examining the impact of mathematical aptitude not only at the commencement of undergraduate programmes but also throughout the economics and business courses undertaken by students. Using a dataset comprising over 4,700 students from the Faculty of Economics and Business at the Autonomous University of Barcelona, empirical patterns are identified to underpin the conclusions. These findings provide valuable insights for the development of targeted interventions aimed at addressing disparities in mathematical competencies that contribute to academic inequalities. Furthermore, the effects of such variations on learning outcomes across economics and business programmes are explored.
Equity offerings are an option available to companies to raise capital. The aim of this paper is to study the occurrence of market anomalies in this context. Using a sample of more than 40,000 equity offerings from 25 countries, an event study has been conducted to estimate and explain abnormal returns around the announcement date. The results demonstrate the existence of significant abnormal returns, robust to different regulations. We also identify factors that appear to be related to its formation, such as being listed on a benchmark stock index or the liquidity of the company's shares.
This study examines the relationship between environmental responsibility (ER) and financial performance (FP) using data from Mexican publicly listed firms between 2018 and 2022. Employing a suite of econometric techniques-including static panel data models, the Generalized Method of Moments (GMM), and Propensity Score Matching (PSM)-we address potential endogeneity concerns to ensure robust estimation. ER is proxied by firm participation in the Carbon Disclosure Project (CDP), while FP is assessed through return on assets (ROA). The findings reveal that ER does notsignificantly enhance FP, suggesting that the costs associated with environmental initiatives may outweigh immediate financial benefits. However, this relationship is conditional on firm growth, with high-growth firms showing a greater capacity to absorb the compliance-related costs of ER, rather than deriving financial gains from these initiatives.
