MB MC The Invisible Hand Theory Profits and Losses Would Ensure That supplies within a market would be distributed efficiently (rationing function) Outputs will go to those consumers who value them the most (i. e. who can pay the most) Resources would be allocated across markets to produce the most efficient possible mix of goods and services (allocative function) Inputs will go to those producers who can pay the most for them (i. e. who can create the highest valued products from them) Markets balance possibility with desirability Copyright c 2004 by The Mc.

All rights reserved. Chapter 8: The Quest for Profit and the Invisible Hand 9
MB MC The Invisible Hand Theory In the long-run, in a competitive market, all firms will tend to earn zero economic profits. Consumer gets the good as cheaply as possible But remember, normal profits cover all the costs of production Zero economic profits are the consequence of price movements caused by the entry and exit of firms trying to maximize economic profits.

The Demand Marginal Cost Curves for a Monopolist MB MC Why the Invisible Hand Breaks Down Under Monopoly Price ($/unit of output) 6 Marginal cost Deadweight loss • Because MR < P, the monopoly produces less than the socially optimal amount • The deadweight loss of the monopoly to society = (1/2)($2/unit)(4 units/wk) = $4/wk. 4 3 2 MR 8 12 Quantity (units/week) Copyright c 2004 by The Mc.
