"In the last hundred years or so, the neo-classical school has come to dominate micro-economic thinking. Economists concerned with competition have taken refuge in increasingly complex models which emphasise the end-state of competitive equilibrium; for a time the classical economists' interest in the disequilibrium adjustments which lead up to such a state all but disappeared.Enquanto nós acreditamos nas imperfeições do mercado, enquanto nós trabalhamos para tornar a concorrência imperfeita... a corrente económica dominante pretende precisamente atacá-la e acabar com ela.
The economic policy consequences of this dominance have been momentous. Concentration on the equilibrium state of 'perfect competition' leads to a search for 'imperfections' and 'failures' in markets. It is a short step to proposals for government action to correct such failures. Indeed, since all real-world markets must appear imperfect when set next to the perfectly competitive ideal, the scope for government intervention seems virtually unlimited."
