Analysis of the difference between the lowest and second lowest bids, or bid-spread, in a ‘lowest wins’ auction is of possible value in strategic bidding; providing an indication of mistakes in bids; determining a justifiable amount of bid security; and a means of providing some insight into...

With notably few exceptions, bidding models contain probability distributions with parameters that are assumed to be fixed, or stationary, over time. Some methods of method of testing the tenability of this assumption are examined and applied to eight datasets. Of particular interest is the...

Multiple regression is used to construct a prediction equation relating bidder competitiveness (the dependent variable) to the independent variables of bidder, contract type and contract size. The regression model shows that differences in contractor competitiveness are greater for different...

This paper discusses the content, origin and development of tendering theory as a theory of price determination. It demonstrates how tendering theory determines prices and how it is different from game and decision theories, and that in the tendering process, with non-cooperative, simultaneous,...
