In Economics. the tenn ‘rent’ is being increasingly used in the sense of a surplus i.e.. what a factor of production earns over and above what is essential to maintain its supplies in its present occupation. It can be easily understood.

TIle supply of land in general, though not for a particular use, is absolutely inelastic, and as such, its supply i. independent of what it earns. That is a higher rent cannot attract more or it and a lower rent cannot drive II out.

Thit simply due t fact that they arc scarce in relation to demand for them
