Answer 1

Answer:

1. $4 trillion or $4,000 billion
2. $3.5 trillion or $3,500 billion

Explanation:

1. Equilibrium Output or GDP is calculated by the expression;

Output or Y = Consumption + Investment + Government expenditure + Net exports

Net exports and Government expenditure are assumed to be 0.

Consumption  = 100 + 0.9Y

Investment = $300 billion

Y = 100 + 0.9Y + 300

Y - 0.9Y = 400

Y = 400/0.1

Y = $4,000 billion

2. Y = 50 + 0.9Y + 300

Y - 0.9Y = 350

0.1Y = 350

Y = 350/0.1

Y = $3,500 Billion
