Acording to this definition, Ebay can be considered a market because in this website there are sellers offering different types of products and buyers willing to pay in order to get them.
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 /
; 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
Answer:
7%
Explanation:
nominal interest rate = real interest rate + expected inflation rate
nominal interest rate = 5% + 2% = 7%
Usually the nominal interest rate has four major components:
- real interest rate: the net interest rate received by a lender or an investor
- inflation rate: the general rise in the prices of goods and services, as inflation increases, the purchasing power of a currency decreases
- liquidity risk premium: usually collateralized loans include a liquidity risk premium since not all assets can be easily converted to cash.
- credit risk: possibility of the borrower defaulting the loan
Consumer surplus is the difference between the maximum
amount the consumer is willing to pay for the price of the good and the price
that was actually paid by the consumer or commonly known as the current market
price. The price that the consumer is willing to pay is determined by the
demand curve in the market.
