Answer:
a. The situation can be shown with a normal equilibrium supply and demand graph (as shown in the attached file).
b. There is a shift in demand from left to right due to the crowding out of the deficit budget.
Step-by-step explanation:
If the government is running a deficit budget, there will be an increase in the total demand for loanable funds. This is because the government must borrow money to balance the situation. As a result, the interest rate will increase. However, the private demand will remain the same and investment will be less due to the high interest rate.
