GDP Deflator

Question one:

The GDP deflator is a price index that is derived from the real GDP and the nominal GDP, the GDP deflator is calculated by dividing the nominal GDP by the Real GDP and then multiplying by 100, in our case we use nominal expenditure and real expenditure because GDP is also measured using the expenditure method. Therefore we use the following formula to derive the price index:

Price index = (nominal GDP/ real GDP) X 100

The following table summarizes our results:

B = 1368.332775

A = -1123.308961

We state the model as follows:

115 / 127

GDP Deflator

RM4t= – 1123.308961 + 1368.332775 RINTL

Question 6:

RM4t= – 1123.308961 + 1368.332775 RINTL

The following model has a constant and a slope value, from the model it is evident that if we hold all other factors constant and let the value of RINTL to be zero then the value of RM4 will be – 1123.308961, also if we hold all other factors constant and increase RINTL by one unit then RM$ will increase by 1368 units. From our result there it means that an increase in the real interest rate will increase the level of real money supply.

Coefficients:

We test the significance of the autonomous value and slope value at 98% level of test:

We state the null and alternative hypothesis in both cases, we start with the autonomous value :

Null hypothesis H0: a = 0, alternative hypothesis Ha: a ≠ 0. For the slope we state the null hypothesis as H0: b = 0 and the alternative hypothesis as Ha: b ≠ 0. We test both of this hypothesis at 95% level of test taking into consideration the sample size and also a two tail test, the critical value is 2.04523. after determining the standard errors of our coeeficients the following is the results:

The table summarizes the T calculated values, from the above it is evident that we reject the null hypothesis for the autonomous value because the T calculated is greater than the T critical, we accept the null hypothesis for the slope because the T calculated is smaller than the T critical.

For this reason therefore at 95% level of test the autonomous value is statistically significant while at the same level of test the slope value is not statistically significant.

Question 7:

We now estimate the model

118 / 127

GDP Deflator

RM4t= a + b1RINTL + b2RDTE

After estimating the model is stated as follows:

RM4t= – 534.66+ 267.9 RINTL + 1.24 RDTE

This model means that if we hold all factors constant and that the value of b1 and b2 are zero then the value of RM4 will be -534.66, if we hold all factors constant and increase the value of RINTL by one unit then RM4 will increase by 267.9 units, finally if we hold all other factors constant and increase RDTE by one unit then the level of RM4 will increase by 1.24 units.

Statistical significance of the data shows the following results:

Null hypothesis H0: a = 0, alternative hypothesis Ha: a ≠ 0. For b1 we state the null hypothesis

as H0: b1 = 0 and the alternative hypothesis as Ha: b1 ≠ 0, For b2 we state the null hypothesis as H0: b2 = 0 and the alternative hypothesis as Ha: b2 ≠ 0. We test this hypothesis at 95% level of test taking into consideration the sample size and also a two tail test, the critical value is 2.04841. After determining the standard errors of our coefficients the following is the results:

For this reason therefore at 95% level of test both the autonomous value and b1 are statistically significant while b2is not statistically significant at 95% level of test.

Question 8:

We now estimate the model

After estimating the model is stated as follows:

RM4t= -701826551.6 + 686607260.3RINTL + 3279238.325 PI

This model means that if we hold all factors constant and that the value of b1 and b2 are zero then the value of RM4 will be -701826551.6, if we hold all factors constant and increase the value of RINTL by one unit then RM4 will increase by 686607260.3 units, finally if we hold all other factors constant and increase PI by one unit then the level of RM4 will increase by 3279238.325 units.

Statistical significance of the data shows the following results:

Null hypothesis H0: a = 0, alternative hypothesis Ha: a ≠ 0. For b1 we state the null hypothesis

as H0: b1 = 0 and the alternative hypothesis as Ha: b1 ≠ 0, For b2 we state the null hypothesis as H0: b2 = 0 and the alternative hypothesis as Ha: b2 ≠ 0. We test this hypothesis at 95% level of test taking into consideration the sample size and also a two tail test, the critical value is 2.04841. After determining the standard errors of our coefficients the following is the results:

The table summarizes the T calculated values, from the above it is evident that we reject the null hypothesis for the a because the T calculated is greater than the T critical, we also reject the null hypothesis for the b1 because the T calculated is greater than the T critical, we however accept the null hypothesis b2 because the T calculated is smaller than the T critical.

For this reason therefore at 95% level of test both the autonomous value and b1 are statistically significant while b2is not statistically significant at 95% level of test. The coefficient of PI in this model means that as inflation increase then the real money supply will also increase.

Question 10:

Joint hypothersis testing:

Null hypothesis:

H0: b1 = b2 = 0

Alternative hypothesis:

Ha: b1 ≠ b2 ≠0

Given that the value of F is derived from the following formula:

f = ((b1yx1 +b2yx2)/2 ) / (e2/n-3)

we use the following figures:

b1

After calulcation our F value is 0.0000063580, from the table we use the F table to determine the critical value, for our case the critical value is using the 2 degrees of freedom for the numerator and 28 degrees of freedom for the denominator 5.453, this means that we accept the null hypothesis because the critical value is greater than our calculated value, therefore this means that b1 and b2 are not statistically significant.
