What does the first welfare theorem state?
The first fundamental theorem of welfare economics guarantees that any competitive equilibrium is Pareto optimal . ... For example, one possible Pareto optimal competitive equilib- rium in a pure exchange market is a final allocation such that a single consumer owns all the goods.
In the GDP estimates of social welfare, a national estimate of social welfare is made by aggregating the revealed preferences of all ‘persons’ in the economy . The GDP index is used to make judgements about welfare changes in the economy.
