The Case:
Egypt is one of the most popular tourist destinations in the entire world and growing economy of Africa. The Egyptian economy depends on petroleum exports, media, textile and tourism. In 2008, more than 12.8 million tourists visited Egypt providing revenues of nearly 1 trillion rupees. As tourism industry is the major source of revenue for Egypt, suppose
government of Egypt invested Rs. 7 million on tourism to make it more attractive and comfortable for tourists. An overwhelming majority got benefit in the shape of employment, facilities and others. This temptation stimulated the other industries like cement, iron, chemical, tobacco, canned food, shoes and furniture. This boost not only changed the living standards but consumption, saving, inflation, employment, incomes aggregate demand were also improved. The consumption function for the people of Egypt before investment was C = 100 +0.70Y while it was C = 100 +0.75Y after the investment. The analytical view before and after the government investment is given below:

This investment also increased the confidence of producers and consumers and changed the other vital facts and figure of the economy which are given below.

According to above facts and figures, government investment has uplifted the other sectors of the economy.
Requirements:
Using the information given above, calculate:
A. Consumption of the people of Egypt from the given equation after the investment
B. Government spending multiplier before and after the investment
C. Tax multiplier before and after the investment
D. Nominal interest rate before and after the investment
(Note: Write down all relevant steps involved in calculation) (Marks =7+6+6+6)
Solution:
Part A:
Consumption after investment:
C = 100 + 0.75Y
C = 100 + 0.75(15000)
C = 100 + 11250
C = 11350
Part B:
Government spending multiplier before investment:
K= 1/1-MPC
K= 1/1-0.7
K= 1/0.3 = 3.33
Government spending multiplier after investment:
K= 1/1-MPC
K= 1/1-0.75
K= 1/0.25 = 4
Part C:
Tax multiplier before investment
K= -MPC/1-MPC
K= – 0.7/1-0.7
K= – 0.70/0.3 = -2.33
Tax multiplier after investment
K= -MPC/1-MPC
K= – 0.75/1-0.75
K= – 0.75/0.25 = -3
Part D:
Nominal interest rate before the investment
Nominal interest rate = real interest rate + inflation
Nominal interest rate = 5.5% + 2.1%
Nominal interest rate = 7.6%
Nominal interest rate after the investment
Nominal interest rate = real interest rate + inflation
Nominal interest rate = 5.7% + 2.5%
Nominal interest rate = 8.2%
Best of Luck!
