The Fundamental Welfare Theorems The so-called Fundamental Welfare Theorems of Economics tell us about the relation between market equilibrium and Pareto e ciency. The First Welfare Theorem: Every Walrasian equilibrium allocation is Pareto e cient. The Second Welfare Theorem: Every Pareto e cient allocation can be supported as a Walrasian equilibrium.

Welfare-economic analysis has been importantly shaped by the two fundamental theorems of welfare economics. The first theorem states that a well-functioning market (where this has a specific meaning) leads to a Pareto optimal allocation of resources.

The first fundamental theorem of welfare economics is often misunderstood, especially by technical economists. Briefly, the theorem says that a market outcome is efficient (Pareto-optimal). The theorem, as proven with great mathematical beauty by Arrow and Debreu, requires a number of reasonably strong assumptions such as very large numbers of buyers and sellers who have perfect rationality and perfect information.
