Answer:
(i) Base year prices
(ii) between two consecutive years
Explanation:
formula for GDP deflator is (real GDP)/(nominal GDP) x 100 which is the numerator real GDP where prices are valued at the current year adjusted to inflation or deflation and then the denominator where prices are valued at a base year where prices are valued at a nominal year which are not adjusted to any inflation or deflation.
The CPI ( consumer price index) is calculated by determining the rise or fall in price of a good or goods in two consecutive periods which in turn gives us the increase or decrease in price percentage.
Answer:
d. It is best measured using the statistic variance inflation factor (VIF).
Explanation:
Multicollinearity is an important issue in multiple regression model, having many independent/ explanatory variables. Multicollinearity is the situation in which two or more independent variables are highly correlated. It is problematic because it increases the standard error of independent variable coefficient & undermines its statistical significance
Variance Inflation Factor [VIF] is a check & corrective measure of multicollinearity.
- VIF as a multicollinearity check : It quantifies the correlation between one explanatory variable with other explanatory variables.VIF = 1 implies there is no multicollinearity (correlation between independent variables); VIF upto 5 implies there is moderate multicollinearity (correlation between independent variables). VIF > 5 implies high multicollinearity (correlation between independent variables)
- VIF as a multicollinearity correction : Calculating
= σ^2 / ![[TSS j (1 - R^2j)]](https://tex.z-dn.net/?f=%5BTSS%20j%20%281%20-%20R%5E2j%29%5D)
; where TSS = total sum of square of variable j , σ^2 = j variance, R^2 j = R^2 from regressing all other independent variable on variable j
the correct answer is (e) which is all of the above.
Explanation: Customers are king, their satisfaction is the ultimate goal for a business. Unsatisfied customer are difficult to retain as well, hence, their problems must always be welcomed and solved. It also aware the firm or give an idea about what needs to be changed or added. Negative word of mouth is also prevented. Its a chance for an organization to convert dissatisfied customer into highly satisfied customers and chances of retention increases as well.
Answer:
The correct answer is A) the substitution effect
Explanation:
In other words, the substitution effect is when sales fall because the consumers change into cheaper alternatives when its price rises.
