GDP understates economic activity because:Group of answer choicesThe value of intermediate goods and services are not includedIt does not include non-market economic activityPublic goods and services are not includedIt uses market prices to value output

The value of intermediate goods and services are not included: GDP only measures the value of final goods and services, not intermediate goods. This means that the goods and services used in the production process are not counted in GDP, which can understate the total economic activity.

It does not include non-market economic activity: GDP only includes market transactions. This means that it does not account for non-market economic activities such as volunteer work, household work, or black market transactions. This can lead to an understatement of the total economic activity.

Public goods and services are not included: GDP does not include the value of public goods and services such as public education, public health services, and public transportation. These goods and services contribute to economic activity but are not included in GDP, leading to an understatement of total economic activity.

It uses market prices to value output: GDP uses market prices to value goods and services. This means that it does not account for the intrinsic value of goods and services, which can lead to an understatement of total economic activity. For example, a painting sold for $100 is counted as$100 in GDP, even if the intrinsic value of the painting is much higher.

The value of intermediate goods and services are not included: GDP only measures the value of final goods and services, not the intermediate goods used to produce them. This means that a lot of economic activity is not accounted for.

It does not include non-market economic activity: GDP only measures market transactions. It does not include non-market economic activities such as volunteer work, unpaid housework, or black market transactions. This means that a lot of economic activity is not included in GDP.

Public goods and services are not included: GDP does not include the value of public goods and services such as public education, public health services, and public transportation. This means that a lot of economic activity is not included in GDP.

It uses market prices to value output: GDP uses market prices to value goods and services. This means that it does not take into account the value of goods and services that are not sold on the market, such as home-cooked meals or self-built houses. This means that a lot of economic activity is not included in GDP.
