Efficiency in Second-Price Auctions: A New Look at Old Data
The experimental economics literature on second-price sealed-bid private value auctions has established that subjects typically bid more than their value, despite the fact that value bidding is a dominant strategy in such auctions. Moreover, the laboratory evidence shows that subjects do not learn to bid their values as they gain more experience. In the present paper, we re-examine the second-price auction data from Kagel and Levinâ€™s (1993) classic paper. We find that auction efficiency is rising over time, even though the frequency of overbidding is unchanged. We argue that the rise in efficiency is due to a decline in the variability of overbidding. This is consistent with subjects learning to bid more like each other.
