### Economic Analysis Problem Set

Given the following economic identities and functions:

\[ Y = C + I + G + NX \] (Income Identity)

Where:
- \( Y = 6,000 \) (Income)
- \( G = 1,200 \) (Government expenditure)
- \( T = 1,000 \) (Tax)
- \( C = 250 + 0.75(Y - T) \) (Consumption expenditure function)
- \( I = 1,000 - 100r \) (Investment function)
- \( NX = 400 - 400e \) (Net exports function)
- \( r = r^* = 5 \) (Interest rate)

### Tasks

#### (a) Solve for:

(i) **The National Saving**

(ii) **The Trade Balance**

(iii) **The Equilibrium Exchange Rate**

(iv) **Based on your answer in (iii), would you describe Ghana as a net borrower or a net lender and why?**

#### (b) Explain the effect on investment and trade balance in a small open economy like Ghana if most foreign governments decide to embark on fiscal expansion.

#### (c) With the aid of a diagram, explain the effect on saving and trade balance in a small economy like Ghana if the government embarks on fiscal expansion.

#### (d) Analyze the effect on interest rate, investment, and trade balance in a small open economy like Ghana if foreign governments in North America, Australia, Asia, and the European Union (EU) embark on expansionary fiscal policy.
