Final answer:
The politician's claim is only correct if the assumption is that the production possibilities frontier will shift outward due to factors such as increased efficiency, resources, or technological advancements, which would enable the economy to produce more of everything.
Step-by-step explanation:
The question concerns whether a politician's claim that it is possible to obtain 'more of everything' in an economy currently at its production possibilities frontier (PPF) is correct or incorrect. This depends on the assumptions regarding the PPF. If the PPF remains unchanged, the politician would be incorrect because the PPF represents the maximum efficient output levels for goods and services given the available resources and technology. However, if the politician is assuming that the PPF can shift outwards—due to factors such as increased efficiency, resources, or technological advancement—then the claim could be correct.
Over time, as an economy grows, the PPF can shift outward. The reasons for this include an increase in available resources, such as labor and capital, and improvements in technology. Therefore, with an outward-shifting PPF, the economy could indeed produce more of all goods.
