The aim of this paper is to investigate the performance of low-volatility portfolio strategies representing risk aversion after the 2008 global financial crisis. Five investment portfolios were built by taking into consideration the weight distribution criteria defined by the inverse of the standard deviation of assets, the natural logarithm and exponential of these values, as well as the minimum variance and tangent portfolios, based on the SP 500 futures index, dollar futures index, US government long-term bond (10-year Treasury Bond) and gold futures. The design of the strategies used both twelve- and thirty-month rolling windows for the standard deviation and conditional volatility estimates. Mean return of portfolio, risk through standard deviation, Sharpe index, and risk-adjusted return were calculated for evaluation purposes. Results have evidenced that, together, risk-based portfolios using 12-month rolling window or conditional volatility were superior to the tangent portfolio, as well as that the minimum variance portfolio was competitive to other alternatives. The main contribution of the current study lies in the fact that risk aversion was relevant to portfolios’ performance in the post-crisis period.

Due to the ever-changing work environment in the age of digital transformation, project managers need to adapt to an environment which is volatile, uncertain, complex, and ambiguous (VUCA). Many organizations adopt management methods based on strict project management planning, assuming that they are the best way to succeed in any situation. However, projects may depend on flexibility to achieve success. This study aims to analyze the impact of adverse project environments on project success and the effect of the management method choice. A PLS-SEM model is tested on a survey of 332 project professionals. Findings showed that choosing a method that best fits the project’s environment can help catch up on project success only when it undergoes frequent changes throughout its life cycle.

This study aims to determine factors impacting the intention of Micro, Small, and Medium Enterprises (MSMEs) in using fintech lending applications as an optional source of business financing using the technology acceptance model approach. The population in this study were MSMEs in Indonesia. Samples were taken by purposive sampling with the criteria of having used a licensed fintech lending application for business financing. The samples used were 171 samples. This study used structural equation model (SEM) as the analysis technique. The results of this study showed that Perceived Ease of Use had an impact on Perceived Usefulness but had no effect on Attitude Toward Using. The factor Perceived Usefulness had an effect on Attitude Toward Using, and Attitude Toward Using influences Behavioral Intention to Use. Fintech companies can play a role by providing education and empowerment to foster understanding of digital literacy for MSME stakeholders. The governments need to develop policy frameworks that can balance innovation and risk mitigation.

A consolidated research line in Brazil identified the proxies for determining the tax aggressiveness of companies listed on the B3 stock exchange. However, none of these studies identified the instrument used by Brazilian companies to carry out tax aggressiveness. Thus, our research seeks to fill this gap by demonstrating that fiscal aggressiveness results from the Brazilian tax complexity, that providing prerogatives to avoid or delay tax payments. Besides, this study is the first accounting study to demonstrate that special installments reduce the actual value of taxes owed by taxpayers, encouraging them to be tax aggressive. Through the foundations of Game Theory, this research demonstrates the cost-benefit of tax aggressiveness in maximizing the profit of tax avoidance. We examined the best strategic decisions in the tax avoidance game concerning the tax complexity and special installments experienced in Brazil. In this game, the only NASH equilibrium is tax avoidance since it is the only option with a chance of remuneration. Therefore, this research contributes to understanding business behavior concerning the Brazilian tax system and provides subsidies to encourage reform of the current tax complexity.

This study was designed to investigate the influence of eSports fan identification on traditional sports teams and vice-versa, specifically in cases where there is an intersection of soccer teams and the eSports world. The Points of Attachment Index was applied with the theoretical background used mainly being the Social Identity Theory (Tajfel & Turner, 1979). Four substantive hypotheses were translated into a conceptual model. Surveys were collected during eSports events in the city of Rio de Janeiro in 2019. Valid questionnaires collected reached 1,420. Data analysis was completed by applying descriptive analysis, exploratory factor analysis, and confirmatory factor analysis, to verify the reliability of the constructs, as well as the convergent and discriminant validity. The Structural Equation Modeling technique was used to test the substantive hypotheses. The empirical outcomes suggest that the identification of a fan with a soccer club exerts a positive influence on the identification of the fan with the club’s eSports team, but the opposite cannot be stated.
