Question

Between real GDP and nominal GDP, which of these is a better indicator of economic welfare and why?

Answer 1

Between real GDP and nominal GDP, real GDP is a better indicator of economic welfare. The reasons are:

1. Definition of Real vs Nominal GDP:

1. Nominal GDP measures the value of all final goods and services produced within a country during a particular year, valued at current market prices of that year. It can be affected by changes in both price levels and quantities produced.
2. Real GDP measures the value of final goods and services at constant prices (prices of a selected base year), thus removing the effect of inflation or price changes. It reflects changes only in the physical quantities of goods and services produced.

2. Real GDP is better for welfare measurement: Economic welfare relates to the material well-being or the real satisfaction people derive from goods and services. Since nominal GDP can increase simply because of higher prices rather than more goods and services, it can give a misleading indication of welfare. Real GDP, by contrast, shows the actual increase in production and availability of goods and services, so it better captures changes in the standard of living.

3. Per capita real income as an index: Economic welfare is more accurately indicated by real per capita income (i.e., real GDP divided by population), as it reflects average availability of goods and services per person, which is directly related to standard of living.
