Answer and Explanation:

Economic Growth can be defined as an increment in production capacity of an economy using all its available resources. The PPF illustrates the largest possible quantity of goods and services a nation can produce base on its available resources. An outward shift in the economy’s production possibility frontier (PPF) depicts  a raise in productive capacity of an economy.  An outward shift implies that an economy has capacity to  increase its production outputs. This can be as a result of   the economy employing new technology, allowing specialization, increasing its labour force, using new production approaches etc. Likewise, an inward shifting PPF implies an economy has witness a loss or exhaustion of some of its scarce resources and it will culminate into reduction in an economy’s productive potential.

Standards of living will be affected, as private consumption will have access to fewer resources. However, in the longer run, the raised production of capital goods will boost  the production of more consumer goods ad therefore standards of living will experience more increase than they would have witness if the economy had spent most of its income on consumer goods.
