Final answer:
An increase in aggregate expenditures affects aggregate demand, not long-run aggregate supply, so it is the correct answer. It does not directly impact an economy's long-term productive capacity.
Step-by-step explanation:
The question asks which of the provided options would not cause a shift in the long-run aggregate supply (LRAS). The long-run aggregate supply represents the total output of an economy at full employment. Changes in LRAS occur due to factors that affect an economy's potential output, such as technology, productivity, labor force, and capital.
- An increase in aggregate expenditures primarily affects aggregate demand rather than long-run aggregate supply.
- A decrease in capital investment will likely reduce the future productive capacity of an economy, shifting LRAS to the left.
- A technological advance in the consumer goods market would improve production efficiency, shifting LRAS to the right.
- An increase in education for employees can enhance human capital, which might increase productivity and potential output, shifting LRAS to the right.
- An influx of skilled immigrants expands the labor force and can increase the productive potential of an economy, shifting LRAS to the right.
Therefore, the correct option is An increase in aggregate expenditures as it does not directly affect the long-run productive potential of the economy but rather affects the current demand for goods and services.
