Besides that, some control variables are included: same postal code of firm and project site, same district and same state, open format auctions, heavy construction auctions, and bidder is a general contractor.
Based on the construction sites׳ and bidders׳ postal codes, we used Microsoft׳s Bing Maps to calculate the driving distances for all bidders to the project sites corresponding to the auctions.
Using data from Austrian construction procurements, we estimate bidders׳ construction costs within a private value auction model.
Section 3 presents the theoretical background and the econometric model of the distribution of bidders׳ construction costs.
This section describes the theoretical model, the econometric model of the distribution of bidders׳ construction costs and the hypotheses for our empirical analysis.
Based on estimated bidders׳ construction costs, we are able to calculate bidders׳ profits and then also their entry cost: (11) Π i (X, Z, N ) = ∑ N ⊆ M π i (X, Z, N, M ) Pr [ N | X, Z, M, i ∈ N ], where Pr [ N | X, Z, M, i ∈ N ] is the probability that N bidders enter given that i enters.
To illustrate the econometric model and the structural estimation of the distribution of bidders׳ construction costs, we use sealed-bid data to estimate the parameters of the theoretical model as a function of auction and bidder characteristics making use of the approach developed by Guerre et al. (2000).
Several established local companies said they had lost out even after bidding several hundred thousand dollars lower. "It kind of boils my blood a little bit, all the money that was spent, when I know it could have been done for less," said Deborah Jones, an owner of daj Construction, one of four lower bidders who failed to win a recent contract for a school renovation in the Austin area.
A spokeswoman says the company was part of one of three bidders for the £230m construction scheme.
He attributed the delays to "issues" with the low bidder of the main construction contract, who eventually withdrew.
