Efeitos da participação de consórcios nos lances e deságios em leilões de transmissão de energia elétrica no Brasil

Abstract

This work aimed to evaluate the effects of consortia participation on bids and discounts in electric power transmission auctions held in Brazil from 2000 to 2011. We considered pooled models with all bids (606 observations) and time series models with the winning bids (148 observations). These models were estimated by Ordinary Least Squares (OLS) and treatment effect. The results indicated that consortia were less competitive than individual firms, since they provided, on average, higher bids and lower discounts. The number of participants, as expected, had competitive effect on bids and discounts. The revenue, in turn, was positively related to bids, but didn't have significant impact on discounts.
