[en] FAVORITISM AND INFORMATIONAL EFFECTS IN PUBLIC PROCUREMENT AUCTIONS / [pt] FAVORITISMO E EFEITOS INFORMACIONAIS EM LICITAÇÕES PÚBLICAS

BRENO DE CASTRO VIEIRA 29 November 2021 (has links)
[pt] O trabalho desenvolve um modelo de licitações públicas com favoritismo e uma regra de decisão em dois estágios. Devido à existência de favoritismo, a qualidade mínima exigida pela agência para aprovar um projeto é determinada de forma a beneficiar uma das firmas. Mostramos que, mesmo supondo simetria ex-ante entre as firmas participantes e independência entre as distribuições de custo e qualidade, as ofertas de preço serão assimétricas em equilíbrio. Em particular, a firma beneficiada escolhe preços maiores do que as demais para um dado nível de custo. Além disso, simulações do modelo indicam que revelar o número de participantes qualificados diminui o preço que o governo espera pagar pelo bem. / [en] We study procurement auctions under favoritism and a two-stage decision rule. Because of favoritism, the minimum quality required in order to approve a project is endogenously determined to benefit the recipient of the agency s bias. We show that, even with ex-ante symmetry and independence between the distributions of costs and quality, equilibrium bidding behavior will be asymmetric and the favorite firm will bid less aggressively than the others. A mechanism design approach indicates that revealing the number of qualified participants or adopting a second-price rule would decrease expected prices and costs of realizing the project, due to the elimination of the asymmetric bidding behavior. Finally, simulations for the uniformly distributed case show that while adopting one of the alternative rules increases efficiency, it also increases the favorite firm s ex-ante profits and therefore may facilitate collusion between the agency and a firm.
