Pareto efficient

Why is the first fundamental theorem of welfare economics important?
-First fundamental theorem of welfare economics (also known as the “Invisible Hand Theorem”): any competitive equilibrium leads to a Pareto efficient allocation of resources. … This theorem is important
because it allows for a separation of efficiency and distribution matters
.
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.

a way for economists to simplify economic processes and make them easier to study and understand
. An assumption allows an economist to break down a complex process in order to develop a theory and realm of understanding.
What is an Edgeworth box and how it is used in welfare economics?
In economics, an Edgeworth box, sometimes referred to as an Edgeworth-Bowley box, is
a graphical representation of a market with just two commodities, X and Y, and two consumers
. … Points within the box represent ways of allocating the goods between the two consumers.
What are the objectives of welfare economics?
