In this write-up we provide intuition behind the two fundamental theorems of wel-fare economics and discuss their properties. An economy is de ned by: the number of 1. The First Fundamental Theorem The doctrine that competition somehow maximizes social welfare dates back to the eighteenth century, and the idea that social welfare is quite simply the arithmetic sum of independent individuals’ welfare is at least as old as Jeremy Bentham.

Firms and consumers take prices as given. The theorem is sometimes seen as an analytical confirmation of Adam Smith's "invisible hand" principle, namely that competitive m 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. First Welfare Theorem (illustration by the Edgeworth Box) The competitive equilibrium (the tangency) is Pareto efficient unless… Public goods (positive externality) Externality (negative ones, e.g. pollution) Negative externalities are related to not well-defined property rights Unsecure property rights 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.

Proof: Assume that the theorem is not true.
