Step-by-step explanation:
GDP formula is :
GDP= Consumption (C)+ Investment (I)+ Government expenditure (G)+ Net exports (exports-imports)
1.The costs of overfishing and other overly intensive uses of resources
It is not accounted because GDP only measures the market value of goods and services produced. The cost of overfishing does not fit in any GDP account.
2. The value of babysitting services, when the babysitter is paid in cash and the transaction isn´t reported
Reported cash services often sum in the consume account but if there is no record it is not accounted in the GDP calculation.
3. Funds spent by city governments to renovate their buildings
It is accounted in the GDP calculation as a government expense (G)
4. A car that is made in Canada, and sold in the United States
It is accounted because it is consumed in the United States. This should be included in the imports account.
5. The quality of goods available to consumers.
The quality is measured in some way because prices reveal at some level the good or service quality. But it is not an accurate measure because there are some goods and services which quality is not represented in their price.
