3.Which of the following would not cause a shift in long-run aggregate supply?

An increase in aggregate expenditures.
A decrease in capital investment.
A technological advance in the consumer goods market.
An increase in education for employees.
An influx of skilled immigrants.

Answer 1

1.) The expenditure multiplier is 2.
The formula for expenditure multiplier is 1 / (1 - MPC). MPC is the marginal propensity to consume which can be computed by the change in spending over the change in income.
MPC = 8500 - 7500 / 12000 - 10000
MPC = 1000 / 2000
MPC = 0.5
expenditure multiplier = 1 / (1 - 0.5)
expenditure multiplier = 2

2.) I think you forgot one option. The answer should be decrease/increase.
Because people will begin to purchase now, if a shortage is expected, which will increase price level because quantity demanded will increase. The output will decrease because supply decreases.

3.) A - An increase in aggregate expenditures.
Because aggregate expenditure is an aggregate demand, not supply.
