Chapter 19: Problem 15

What is the difference between a series of economic data over time measured in nominal terms versus the same data series over time measured in real terms?

Short Answer

Expert verified

In conclusion, the difference between a series of economic data measured in nominal terms and real terms lies in the effect of inflation. Nominal data is the raw, unadjusted data measured in current prices, whereas real data is adjusted for inflation, reflecting the true purchasing power of an economic variable. Comparing the two is essential for understanding the actual behavior of the economy and making informed economic policy decisions.

Step by step solution

Define Nominal Terms

Nominal data refers to the raw data related to an economic variable that does not account for the effect of inflation or changes in the purchasing power of money. This data is the most basic version of a dataset; it is measured in current prices and has not been adjusted for inflation.

Define Real Terms

Real data, on the other hand, is the economic data that has been adjusted to remove the effects of inflation. This means that any changes observed in this data over time are driven by underlying changes in the economy and not simply due to changes in the price level. Real data reflects the true purchasing power of an economic variable.

Compare Nominal and Real Terms using an example

For example, consider a country's Gross Domestic Product (GDP) over the years. GDP in nominal terms refers to the market value of all goods and services produced in a given year, using current prices. Real GDP, however, is the same GDP adjusted for inflation, showing the 'real' growth in the economy. If we only look at the nominal GDP, it would seem that the economy has grown faster than its actual growth rate due to price level changes. However, using real GDP, the growth rate is more accurate, as it eliminates the price level changes and only considers the actual output growth.

Explain the importance of comparing Nominal and Real terms

Comparing Nominal and Real terms is essential because it allows us to distinguish between the changes in the economy driven by true economic growth and those driven by inflation. Using real data can help policymakers make more informed decisions about the economy's underlying performance to develop appropriate policies. In conclusion, comparing a series of economic data over time in nominal terms does not account for the effect of inflation, while the same series measured in real terms has been adjusted to remove those inflation effects. This distinction is crucial for understanding the actual behavior of the economy and for making better economic policy decisions.
