This aspect is particularly important where there is a trade-off between quality and yield, as in the case of a higher-yielding, but lower-quality wheat variety. The aim of this paper is to incorporate these quality aspects into an analysis based on a partial equilibrium framework by separating the wheat market into segments based on wheat quality. A change in the type of wheat produced can then be... |
