Answer:
Explanation:
a. When the United States experiences a wave of immigration, the labor force increases, therefore there would be an increase in the long-run aggregate supply because there are more people who can produce output.
b. When Congress raises the minimum wage to $10 per hour, the natural rate unemployment decreases, thus, leading to the shifting of the long-run aggregate-supply curve to the left.
c. When Intel invents a new and more powerful computer chip, productivity increases, therefore, there would be an increase in the long-run aggregate because more output can be produced with the same inputs.
d. When a severe hurricane damages factories along the East Coast, the capital stock is smaller, thus leading to a decline in the long-run aggregate supply.
