Abstract in Portuguese
Nós comparamos o leilão aberto e o leilão selado utilizados para compras públicas na Bolsa Eletrônica de Compras (BEC) do Estado de São Paulo usando dados das transações de açúcar refinado entre 2008 e 2011. O leilão selado gera uma economia para o Estado de aproximadamente 3% em relação ao leilão aberto. Sob a ótica do paradigma de valores privados independentes, nós adotamos um modelo com licitantes assimétricos e aversão ao risco. Ao recuperar a propensão a pagar dos participantes com econometria estrutural, descobrimos que estas hipóteses se encaixam razoavelmente bem aos leilões, ainda que não possamos descartar conluio ou comportamentos gerados por leilões online

Abstract in English
We compared the open and the sealed bid auctions used for procurement transaction at the electronic platform Bolsa Eletrônica de Compras (BEC) of São Paulo state using data from refined sugar purchases between 2008 and 2011. The sealed bid generates lower prices in about 3% compared to the open auction. Under the independent private values paradigm, we adopted asymmetric bidders and risk aversion. We recover with structural econometrics the cumulative distribution functions of cost of potential bidders and we found evidence we can fit reasonably well our data, although we cannot reject collusion or behaviors generated by online auctions.
