Answer
Today’s markets involve demand and supply which are defined by quality of sensible selection rather than price (matchmaking).
Step-by-step explanation
For example the school admission program in a city X allows only few students to proceed to the schools they want because the students were left with limited choices that do not allow for proper matching. This is so because first the selection was done by mail where the students ticked the school they wanted then the list is returned to the school to await selection results. The ticked option is over-picked by many students making the extra number shifted to other schools which they did not select. No right matching was made here.
