I use land auction data in Taipei City and in Taipei County to test Sherman’s (2005) information production theory. Results show that bidders in Taipei City (a core metropolitan area) and those in Taipei County (a suburb) have different bidding behavior. I find that bids in Taipei City’s land auctions are generally consistent with the predictions of auction theory for informed bidders. They tend to expend resources to collect information and shave their bids optimally. However, bids in Taipei County exhibit uninformed and overbidding behavior.
