- Calculate Aggregate Income (Y): The aggregate income in a Keynesian framework is given by the equation:
Where:
• C is the consumption function: C = C0 + MPC × (Y - T)
• C0 is autonomous consumption.
• MPC is the marginal propensity to consume.
• I is investment.
• G is government spending.
• T is taxes (depends on Y).
- Initial Calculation Without Considering Taxes (T): Assume T = 0 for the initial calculation.
C = 38 + 0.62 × Y I = 30.5 G = 37 Y = 38 + 0.62 × Y + 30.5 + 37
Solve for Y:
0.38Y = 105.5 Y ≈ 277.63
- Calculate Taxes: Apply the tax rate (11%) to the aggregate income to find total taxes (T).
T = 0.11 × Y T = 0.11 × 277.63 T ≈ 30.54
- Re-calculate Aggregate Income with Taxes: Insert the tax value back into the consumption function and re-calculate Y.
C = 38 + 0.62 × (Y - 30.54) Y = 38 + 0.62 × (Y - 30.54) + 30.5 + 37
Solve this equation for Y.
- Determine Government Budget Status: The government's budget situation is:
Budget = T - (G + Transfers)
Calculate using the values:
Budget = 30.54 - (37 + 20) Budget = 30.54 - 57 Budget ≈ -26.46
A negative value indicates a budget deficit.
This approach gives an approximation of the government's budget situation based on the provided data and economic assumptions.
