Efficiency in Production

1. Producers all face the same price ratio

for inputs

2. Implies on Production Contract

Consumption Box smaller than need be)

3. Size of Consumption Box = fn (where

on production contract curve we are)

4. Distribution of Income = fn ( Production

Contract curve point as well as inputs possessed by society i.e. depends on initial endowments and property rights)

5. Change Endowments and/or property

The Invisible Hand

…and by directing industry in such a manner as its produce may be of the greatest value, he intends only his own gain and he is in this, as in many other cases, led by an invisible hand to promote and end which was no part of his intention. Nor is it always the worse for society that it was no part of it. By pursuing his own interest he frequently promotes that of society more effectually than when he really intends to promote it.

Adam Smith, The Wealth of Nations, 1776

But…

„ Efficiency is non-unique.

„ Different initial endowments and

property rights different efficient

outcomes.

„ Perfect competition “solves” the

efficiency question, but not equity.
