SUMMARY:

The central thesis of this research work is that there is a set of variables on a micro and macro scale that have an influential role in the probability of occurrence of fraud or anticompetitive practices in public e-procurement bids. Thus, this thesis in the format of "three articles" analytically and empirically verified the integrity of public purchases through electronic auctions in the Brazilian Public Purchasing System, also considering the dynamics of this systemic process. An Analysis was carried out based on the hiring of services that occurred in the Brazilian Federal Government's Purchasing Portal, in the period from 2014 to 2018, aiming to enable the suggestion of actions to mitigate the problem. The first study used the Newcomb-Benford Law - NB, or Law of Anomalous Numbers, to analyze values of the mentioned Electronic Bids, aiming to identify indications of fraud. The results of this study point to statistically significant indications of fraud in the evaluated population. The second study used the logit Regression model, with a binary dependent variable to model the probability of fraud, y, as a function of a vector, x, of explanatory variables formed by the characteristics of the Bidding Process and the Supplier, and with that, it was quantified, in probabilistic terms, the relation between the explanatory variables and the occurrence of fraud in the auctions and it was also analyzed which is the marginal effect, in probabilistic terms, of a given explanatory variable on this probability. In the last stage of the research, the mathematical modeling technique of System Dynamics was used to analyze the relationship between several variables, on a micro and macro scale, with the occurrence of fraud in the Electronic Auctions system, aiming at the development and calibration of the mathematical model. A scenario analysis and the proposition of strategic actions aimed at mitigating the risk of occurrence of anti-competitive practices in electronic auctions were carried out. The results show that there is a set of quantitative variables and specific conditions related to Electronic Public Biddings that have an influential role in the probability of fraud occurrence.
