Abstract

The literature on serious games (SGs) indicates that they are very useful tools to improve the teaching/learning process. In this paper, we analyze some potential benefits of a SG on academic performance of undergraduate accounting students. The database is comprised of scores obtained by students during an undergraduate discipline related with accounting history. The game was presented to the students during the academic semester of the discipline; they also developed an academic activity using the concepts of this game. The main results of the paper indicate that students who used the game and scored the maximum grade in this activity also registered higher indexes of academic performance in such discipline. These results reinforce the benefits of the SG to interact with undergraduate students and teach academic content.

Author

Fernandes Malaquias, Rodrigo, Zambra, Pablo, Fernandes Malaquias, Rodrigo, and Zambra, Pablo

Abstract

The main purpose of this paper is to analyze the risk-adjusted performance of Brazilian commodity metalrelated funds considering the Covid-19 pandemic. The database is comprised of Brazilian investment funds during the period from January, 2005 to June, 2021. Using daily returns, each quarter, we employed the Return Based Style Analysis to identify metal-related funds. The study hypothesis was tested through panel data regressions. On one hand, the main results suggest that, during Covid-19 pandemic, metalrelated funds performed better in comparison to the other investment funds. This result was also persistent considering different measures for fund performance. On the other hand, the performance of metal-related funds was equivalent to the performance of the other funds during the Global Financial Crisis. The quantitative analysis also considers the effects of number of confirmed cases for Covid-19 and total vaccination on fund’s daily returns., El objetivo principal de este estudio es analizar el desempeño ajustado al riesgo de los fondos relacionados con los commodities metálicos considerando la pandemia de Covid-19. La base de datos está compuesta por fondos de inversión brasileños durante el período de enero de 2005 a junio de 2021. Utilizando rendimientos diarios, cada trimestre, empleamos el Análisis de estilo basado en rendimiento para identificar fondos relacionados con metales. La hipótesis del estudio se probó mediante regresiones de datos de panel. Por un lado, los principales resultados sugieren que, durante la pandemia de Covid-19, los fondos relacionados con los metales tuvieron un mejor desempeño en comparación con los otros fondos de inversión. Este resultado también fue persistente considerando diferentes medidas para el desempeño del fondo. Por otro lado, el desempeño de los fondos relacionados con los metales fue equivalente al desempeño de los otros fondos durante la Crisis Financiera Global. El análisis cuantitativo también considera los efectos del número de casos confirmados de Covid-19 y la vacunación total en los rendimientos diarios del fondo

Abstract

Investment funds manage a portfolio composed of financial instruments; therefore, their accounting reports should undergo a careful process of preparation and auditing. The main purpose of this study is to analyze the effect of being audited by a Big Four audit company on funds' risk-adjusted performance. The database is composed of equity funds from the Brazilian financial market, with daily returns spanning from January 2005 to March 2023. The funds' performance was measured based on three indicators, including the Sharpe Ratio and Jensen's Alpha. Fama and MacBeth regressions were used to test the hypotheses. The main findings indicate that the benefits of audit quality also include a positive effect on the risk-adjusted performance of investment funds, as the coefficient of the variable "Big Four" was positive and significant based on the proxies for risk-adjusted performance. This study advances this area of research by demonstrating the effects of the type of audit on the risk-adjusted performance indicators of investment funds. [ABSTRACT FROM AUTHOR]
