Skitmore, M (1991) The construction contract bidder homogeneity assumption: An empirical test. Construction Management and Economics, 9(5), pp. 403-429. ISSN 01446193
Abstract
This paper describes an empirical study to test the proposition that all construction contract bidders are homogeneous, i.e. they can be treated as behaving collectively in an identical (statistical) manner. An examination of previous analyses of bidding data reveals a flaw in the method of standardizing bids across different size contracts and a new procedure is proposed which involves the estimation of a contract datum. Three independent sets of bidding data were then subjected to this procedure and estimates of the necessary distributional parameters obtained. These were then tested against the bidder homogeneity assumption, resulting in the conclusion that the assumption may be appropriate for a three-parameter lognormal shape, but not for scale and location.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
