Explanation of Solution
The consumer
Substitute the respective values in Equation (1) to calculate the CPI for year 1.
Total cost in the year 1(base year) is $26,
Thus, CPI for year 1 is 100.
The cost increased to $29 in year 2. Then, substitute the respective values in Equation (1) to calculate the CPI for year 2.
Thus, CPI for year 2 is 111.54.
The total cost in year 3 is $30.20. Then, substitute the respective values in Equation (1) to calculate the CPI for year 3.
Thus, CPI for year 3 is 116.15.
The total cost in year 4 is $30.5. Then, substitute the respective values in Equation (1) to calculate the CPI for year 4.
Thus, CPI for year 4 is 117.30.
Consumer Price index (CPI): Consumer price index is a measure that examines the changes in price levels of a basket of consumer goods and services for the present time from base year.
(b)
The rate of inflation in year 2, year 3, and year 4.
(b)
Explanation of Solution
The rate of inflation is calculated using Equation (2):
In case 1, the consumer price index for this year is 111.54 and the consumer price index for the previous year is . Thus, the rate of inflation in the economy can be calculated using these values and substituting them in Equation (2) is as follows:
Thus, the rate of inflation in year 2 is 11.54 percent.
In case 2, the consumer price index for year 3 is 116.15, and the consumer price index for the previous year is 111.54. Thus, the rate of inflation in the economy can be calculated by using these values and substituting them in Equation (2) as follows:
Thus, the rate of inflation in year 3 is 4.1 percent.
In case 3, the consumer price index for year 4 is 117.30, and the consumer price index for the previous year is 116.54. Thus, the rate of inflation in the economy can be calculated using these values and substituting them in Equation (2) as follows:
Thus, the rate of inflation in year 4 is 1 percent.
Inflation rate: Inflation rate refers to the percentage change in the price level from the preceding period.
(c)
The real GDP in each of the four years.
(c)
Explanation of Solution
The consumer price index for year 1 is 100, and the corresponding nominal GDP is $5 billion. Thus, the real GDP can be calculated by using these values and substituting them in Equation (3) as follows:
Thus, the real GDP in year 1 is $5 billion.
The consumer price index for year 2 is 111.54, and the corresponding nominal GDP is $5.6 billion. Thus, the real GDP can be calculated by using these values and substituting them in Equation (3) as follows:
Thus, the real GDP in year 2 is $5.02 billion.
The consumer price index for year 3 is 116.15, and the corresponding nominal GDP is $6.1 billion. Thus, the real GDP can be calculated by using these values and substituting them in Equation (3) as follows:
Thus, the real GDP in year 3 is $5.25 billion.
The consumer price index for year 4 is 117.30, and the corresponding nominal GDP is $6.5 billion. Thus, the real GDP can be calculated by using these values and substituting them in Equation (3) as follows:
Thus, the real GDP in year 4 is $5.54 billion.
Real GDP: Real GDP refers to the market value of all final goods and services produced in an economy during an accounting year, measured at constant prices.
Nominal GDP: Nominal GDP is the market value of all final goods and services produced in an economy during an accounting year, measured in current prices.
(d)
The percentage increase in nominal GDP as a result of inflation from the year 1 to 4.
(d)
Explanation of Solution
There is a 30 percentage increase in the nominal GDP from the year 1 to 4.
For 17.3 percentage change in the price level:
Therefore, the inflation represented as follows:
Thus, the inflation represents a 57.67% of rise in nominal GDP.
