  1. PUBLIC CHOICE THEORY OF GOVERNMENT INTERVENTION

  2. MODELS OF GOVERNMENT Despotic benovelent government model The fiscal exchange model The fiscal transfer model The levitahan model

  3. Voter First Choice Second Choice Third Choice Groucho Police Tourism Bridge Bridge Police Tourism Harpo Tourism Bridge Police Chico Political exploatation of majority voting rule Town Council Rankings For Bond Fund

  4. Voting Cycle • Tourism vs Police • Winner = Police • Police vs Bridge • Winner = Bridge • Bridge vs Tourism • Winner = Tourism • Continuous cycle (no equilibrium)or arbitrary winner depending on order

  5. BUREAUCRATIC EMPIRE BUILDING

  6. CATEGORIZING INEFFICIENCY • X-inefficiency • It is argued that a bureaucracy has less incentive to cut costs because it doesn't face competition from other organizations.Therefore the AC curve is higher than it should be. • Allocative inefficiency • A monopoly is allocatively inefficient because in monopoly the price is greater than MC. P > MC. In a competitive market the price would be lower and more consumers would benefit

  7. Monopoly Costs / Revenue AR (D) curve for a monopolist likely to be relatively price inelastic. Output assumed to be at profit maximising output (note caution here – not all monopolists may aim for profit maximisation!) Given the barriers to entry, the monopolist will be able to exploit abnormal profits in the long run as entry to the market is restricted. This is both the short run and long run equilibrium position for a monopoly MC £7.00 Monopoly Profit AC £3.00 AR MR Output / Sales Q1

  8. Monopoly Welfare implications of monopolies Costs / Revenue MC The higher price and lower output means that consumer surplus is reduced, indicated by the grey shaded area. The price in a competitive market would be £3 with output levels at Q1. The monopoly price would be £7 per unit with output levels lower at Q2. On the face of it, consumers face higher prices and less choice in monopoly conditions compared to more competitive environments. £7 A look back at the diagram for perfect competition will reveal that in equilibrium, price will be equal to the MC of production. We can look therefore at a comparison of the differences between price and output in a competitive situation compared to a monopoly. AC Loss of consumersurplus £3 AR MR Output / Sales Q2 Q1

  9. Monopoly Welfare implications of monopolies Costs / Revenue MC The monopolist will be affected by a loss of producer surplus shown by the grey triangle but…….. The monopolist will benefit from additional producer surplus equal to the grey shaded rectangle. £7 AC Gain in producer surplus £3 AR MR Output / Sales Q2 Q1

  10. Monopoly Welfare implications of monopolies Costs / Revenue MC The value of the grey shaded triangle represents the total welfare loss to society – sometimes referred to as the ‘deadweight welfare loss’. £7 AC £3 AR MR Output / Sales Q2 Q1

  11. SCOPE FOR DISCRETIONARY BEHAVIOUR BY BUREAUCRATS • Asymmetric information • Asymmetric tay liability • Asymmetric consumption benefits • Asymmetric voting paterns
