Question

Suppose the price of apples doubles to $3.00 between year 1 and year 2 but that nothing else in the economy changes Instructions: Round your answers to one decimal placea. What would be the percentage change in nominal GDP? b. What would be the percentage change in real GDP?Suppose the prices of both apples and bread double between year 1 and year 2 and quantities remain unchanged. Instructions: Round your answers to one decimal place a) What would be the percentage change in nominal GDP?% b) What would be the percentage change in real GDP?

Answer 1

Answer:

1. Suppose Quantity of Apple sold in year one & two =  100Kg.

Price in year 1 = $1.50 per kg

Price in year 2 = $3.00 per kg

Nominal GDP 1 = Price * Quantity = 1.50*100 = $150

Nominal GDP year 2 = 3*100 = $300

Change in Nominal GDP = $150

Percentage change in Nominal GDP = 100%

b. Real GDP of year 1 = Nominal GDP of year 1 = $150

Real GDP of year 2 = 1.50*100 = $150

Change in Real GDP = 0%

2. Quantity of Bread = 100 units price = $ 1 per unit, year 2 price = $ 2 per units

a. Nominal GDP year 1 = 1*100+1.5*100 = $250

Nominal GDP year 2 = 2*100+3*100 = $500

Percentage change in Nominal GDP = 500-250/500 * 100 = 100%

b. Real GDP year 1 = $250

Real GDP year 2 = 1*100 + 1.5*100 = $250

Percentage change in Real GDP = 0%
