Solution
The answer is D: SRAS Increase, LRAS Increase, PPC Increase.
Here's why:
-
Short-Run Aggregate Supply (SRAS): An increase in investment can lead to an increase in the SRAS. This is because investment often leads to an increase in productive capacity, such as more machinery or technology, which allows more goods and services to be produced in the short run.
-
Long-Run Aggregate Supply (LRAS): Similarly, an increase in investment can also lead to an increase in the LRAS. This is because investment can lead to an increase in the economy's potential output over the long run. For example, investment in education can increase human capital, leading to higher productivity and thus a higher potential output.
-
Production Possibilities Curve (PPC): An increase in investment can lead to an outward shift (increase) in the PPC. This is because the PPC represents the maximum combination of goods and services an economy can produce given its resources. If investment increases, this can lead to an increase in resources (such as capital or technology), allowing more goods and services to be produced.
