Answer:
diminishing marginal rates of substitution.
Explanation:
Based on the information provided within the question it can be said that the principle that captures this is known as diminishing marginal rates of substitution. Like mentioned in the question this refers to the fact that a consumer chooses to replace a product instead of actually buying more. This decreases as you move down the indifference curve as shown below.
Answer:
The correct answer is option c.
Explanation:
The nominal interest rate was 5 percent.
The CPI was 150.3 at the end of the year, and the CPI was 144.2 at the beginning of the year.
The 5% nominal interest rate means that the dollar value of savings increased at 5%.
Inflation rate
=
= 0.0423 or 4.2%
The real interest rate
= Nominal interest rate - rate of inflation
= 5 - 4.2
= 0.8%
The real interest rate of 0.8% indicates that the purchasing power of savings increased at 0.8%.
