The first Welfare Theorem is the one that people usually cite. This specifies conditions under which a rational competitive equilibrium will be efficient. In effect, the theorem is the mathematical explanation for Adam Smith's “invisible hand”.

It serves as a theoretical justi cation for the e cacy of markets. The First Fundamental Theorem of Welfare Economics is proof, in view of its long list of prerequisites, that market outcome can be improved by well-designed interventions. Now what is wrong with this is very simple. The First Theorem gives sufficient conditions for a market to be efficient it does not give necessary conditions.

Animated and verbal exploration of surplus in competitive markets. Graphical derivation of consumer surplus, producer surplus and worker surplus are all shown 

Proof: Let (p,x,T) be a Walrasian Equilibrium with Transfers.Suppose x is not weakly Pareto Optimal. Then we can find x ∈ (R2 +) 2 such that x1 + x2 =¯ω xi i xi (i =1,2) x i i xi implies xi i x i When the conditions underlying the first welfare theorem fail to hold, we can expect market failure. Market failure consequently has a very precise mean-ing for economists, despite its often loose usage elsewhere: it requires a failure of the first welfare the-orem … This video was created using Knowmia Teach Pro - http://www.knowmia.com/content/AboutTeachPro as the First Welfare Theorem hold in both models.

The main idea here is that markets lead to social optimum. Thus, no intervention of the government is required, and it should adopt only “ laissez faire ” policies. was the first to describe the system as a whole and to show that a competitive market economy generates a Pareto optimal allocation of resources; a result known as the First Fundamental Theorem of Welfare Economics.
