Gross Domestic Product (GDP) is a widely used measure of economic activity, but it does have limitations. One significant limitation is that it excludes non-market transactions. This includes activities such as household labor, volunteer work, and other services that individuals perform but do not receive payment for. Because these activities contribute to overall economic well-being but do not show up in market transactions, GDP can underestimate the actual economic activity and standard of living of a population.
In contrast, the other options reflect aspects that GDP does not measure accurately. The quality of goods is not inherently accounted for in GDP figures; it merely totals the monetary value of goods and services produced. Income distribution is also not captured by GDP, as this measure aggregates total output without addressing how wealth is distributed among different groups within a society. Moreover, informal economy activities, such as those that are not reported or taxed, fall outside the scope of GDP calculations as they are not tracked in official data.
Overall, recognizing the exclusion of non-market transactions helps to better understand the limitations of GDP as an indicator of economic health and societal welfare.
