1.If the consumer price index (CPI) at year-end was 142 and the beginning of the year was 135, then the rate of inflation during the year is:

A)   5.2%.

B)   2.8%.

C)   4.7%.

D)   6.4%.

The correct answer was A)

The inflation rate can be calculated as (142 –135) / 135 = 5.2%.

2.Which of the following statements regarding inflation is most accurate?

A)   The purchasing power of money increases as a result of inflation.

B)   Inflation has no effect on the real economic output.

C)   Inflation is a persistent increase in the general price level of goods and services.

D)   As a result of inflation, all borrowers gain at the expense of lenders.

The correct answer was C)

Inflation is defined as a persistent increase in the price level over time. Inflation indicates that there has been a general decline in the purchasing power of a currency. Inflation reduces economic output by increasing transactions costs and reducing investment rates. Fixed-rate borrowers gain at the expense of lenders when inflation is greater than expected.

Are the statements as made by Lebow regarding inflation and price levels correct?

Statement 1

Statement 2

A)                   Incorrect                             Incorrect

B)                   Correct                                 Correct

C)                   Incorrect                               Correct

D)                   Correct                               Incorrect

The correct answer was D)

Statement 1 is correct. However, Statement 2 is incorrect because a one-time increase in the price level is not necessarily inflation. Inflation is an on-going process; not a one-time increase in the price level.
