An economist is analyzing economic data for a small country. The table below shows the index for average nominal wages and the index for consumer prices over a four-year period. Year 1 is the base year for both indices.

Based on this data, during which one-year period did the purchasing power of the average worker's wages increase the most?

Interpreting Wage and Price Indices

Analyzing Purchasing Power Trends

In a given economy, over a five-year period, the index for average nominal wages increased from 100 to 120. During the same period, the index for consumer prices increased from 100 to 125. Based on this information, the average worker's purchasing power has increased over this five-year period.

An economist wants to compare the trend in average nominal wages with the trend in consumer prices over a period of several years to understand how purchasing power has changed. Arrange the steps below into the correct logical sequence for creating and using index numbers for this purpose.

An economic analyst is using index numbers to compare wage and price trends, with a specific year chosen as the base year (where all indices are set to 100). Match each economic observation for a subsequent year with the corresponding mathematical relationship or value(s) for the Nominal Wage Index and the Consumer Price Index for that year.

An economist is tracking wage growth and sets Year 1 as the base year, with an average nominal wage of $50,000 and a wage index of 100. In Year 2, the average nominal wage rises to $52,500. The nominal wage index for Year 2 would be ____.

Constructing an Economic Argument with Index Numbers

An economic analyst is comparing wage and price trends in two different countries, Country X and Country Y, over a decade. Both countries use the start of the decade as the base year (Index = 100). At the end of the decade, the data is as follows:

• Country X: Nominal Wage Index = 125, Consumer Price Index = 120
• Country Y: Nominal Wage Index = 115, Consumer Price Index = 105

The analyst concludes: "Workers in Country X experienced a better outcome because their nominal wages grew by 25%, which is a much larger increase than the 15% wage growth in Country Y."

Which of the following statements best evaluates the analyst's conclusion?
