Answer:
The correct answer is option (ii) and (iii).
Explanation:
The unemployment rate will obviously increase with the increase in the number of people who are unemployed.
If there's an increased preference among older men to retire early, this may lead to an increase in the unemployment rate.
If there is an increase in the unemployment benefits or increase in the period in which the government provides benefits to the unemployed workers, it will lead to an increase in the unemployment rate. This is because the incentive will reduce the cost of unemployment.
