Analyzing the Impact of Payroll Exemption on Cost Behavior in the Civil Construction Sector of BM&FBovespa

Résumé

Among the various initiatives of the Federal Government of Brazil to overcome the economic crisis, the incentive for the legalization of work stands out. Brazil is one of the countries with the highest incidence of taxes on workers' payrolls. Therefore, the objective of this research is to analyze the impact of the release of payroll costs on the behavior of companies in the civil construction sector in the BM & FBovespa. The hypothesis is that the behavior of costs is statistically different in the periods before and after the payroll exemption. As methodological procedures, linear regression and the T test were used to check if there are differences between the averages of the values ​​before and after exoneration. The data analytics dashboard identifies Stiky cost behavior over time in the industry. The results do not reject the null hypothesis when the behavior of costs based on CPV/RLV and CT/RLV data is observed. Therefore, it is not possible to say that there is a significant difference between the periods before and after the payroll waiver and the subsequent effective cost reduction.
