Hirota, H. H. The concession market of electricity transmission lines in Brazil. 2006. 88 f. Dissertation (Master Degree)– Faculdade de Economia Administração e Contabilidade de Ribeirão Preto, Universidade de São Paulo, Ribeirão Preto, 2006. This work analised the concession market of electricity transmission lines in Brazil. This market was recently created by a major restructuring in the regulation laws. The reason for this change was the investment crisis that the sector was going through before 1999. Those concessions are decided by an auction and lasts for thirty years. It has been considered a major success, due to the interest of many companies in acquiring this permits. The government no longer invested on it but instead decided de the laws to control the sector. One of the key changes in the diferent aspect of the regulation the participation of the private sector. Investments were no longer dependent on government for financial suport. This alteration made the market more competitive, eficient and lucrative. The auctions are classified as a descending first-price with two stages. The first stage is made with a sealed bid and in case the diference of the lowest bid and the other bids are less than 5%, the auction goes to the second stage with a oral auction. The object auctioned is a permit to provide a public service for a period o time, so this is the reason the auction is descending one. The bids made by the participants is the value of a maximum annual income permited by the regulator. The reason for this maximum is a result of the fact that this public service is a natural monopoly. It prevents the concessionare to take advantage over it ́s clients by charging a high fee when they don ́t have a choice of another provider of this service. When the participants of the auctions choose the value of the bid, this only bid contains all of their expectations of costs, profits, the probability of winning the auction when considering the competition etc. This work uses the data of all the auctions of transmission lines that happened between 1999 and 2005. in this period ocorred ten auctions, with many lines auctioned in each one. In order to determine what made this market so interesting for private companies some caracteristics of those companies were considered. The results of this study finds that the most important caracteristic is interdependencies. It allows lower costs the many concessions the company owns. This result is so powerful that sometimes it may determine the winner of the auction. Other variables analised were the competitiveness of this sequential auctions, the competitiveness of the participants, the kind of work the company is specialized in, as a real option when deciding what kind of company to participate, for exemple, in a joint venture, and the benefits of this decision.
