      abstract = {Wheat protein is one of the most important specifications  used in domestic and
import purchase contracts and is used  partly as a proxy for functional quality. The
purpose of  this article is to analyse the demand for wheat delineated  by protein class.
A choice-based econometric model is  specified and estimated using a novel dataset of
pooled  wheat shipments to individual importing countries. Buyers  are importing
countries that make purchase decisions among  different protein levels. The model
frames the choice in  terms of attributes of the choice and of the importing  countries.
Results indicate that there have been shifts  over time, and purchase probabilities are
highly price  elastic and vary across importing regions. Functional  characteristics
including wet gluten content and extraction  rates have significant impacts on purchase
probabilities.  These results have implications for breeders as it clearly  illustrates the
role of protein and functional  characteristics on demand. The results also have  implications
for analysts modelling wheat trade in that  there are many factors impacting
market segments that would  not be captured in conventional demand specifications.},
