8.

Downward sloping concave PP curve shows increasing Marginal Rate of Transformation (MRT) as more quantity of one good is produced by reducing quantity of the other good. This behaviour of the MRT is based on the assumption that all resources are not equally efficient in production of all goods. As more of one good is produced, less and less efficient resources have to be transferred to the production of the other good which raises marginal cost i.e. MRT.
