  1. Competition Law in Hong Kong Howard Davies

  2. Why Have Competition Law? • In a market economy, it is accepted that the market mechanism will only give the ‘optimal’ result if all industries are subject to competition • WHAT DO WE MEAN BY AN ‘OPTIMAL RESULT’? • WHAT DO WE MEAN BY ‘COMPETITION’?

  3. In formal textbook economic analysis • ‘Optimal’ result is also referred to as an ‘optimal’ allocation of resources, or ‘social welfare maximisation’ • It means producing exactly the ‘right’ amount of each good and service • The ‘right’ amount is where the price is equal to the marginal cost • This happens automatically under ‘perfect competition’

  4. This Is the Formal Version of the Idea of the ‘Invisible hand’ • Adam Smith – ‘The Wealth of Nations’ 1776 • ‘It is not to the generosity of the baker that we owe our bread, but to his pursuit of his own self-interest’

  5. Why and How Does That Happen? • Some board work may help MC –extra cost of one more unit D – extra benefit of one more unit Optimal output

  6. Perfect Competition • Large number of small buyers and seller • Identical products • Free entry and exit • Perfect knowledge of market opportunities • Profit-maximizing behaviour

  7. Perfect Competition • Under perfect competition, price will equal marginal cost of production because every firm is in this situation MC Pm D = AR = MR = Pm

  8. Perfect Competition • For the industry as a whole Supply = horizontal sum of firms’ MC curves Pm

  9. If We Have a Monopoly Situation MC Pprofit max D=AR Poptimal Q optimal Qprofit-max MR

  10. Monopoly Leads to: • A STATIC ‘misallocation’ of resources. • Price not equal to marginal cost. With the existing resources and technology output is less than it could be. Units of a product which consumers value more highly than their cost of production do not get produced • A DYNAMIC misallocation of resources • insufficient attention and resources are devoted to innovation because there is no competitive pressure • CONSUMERS lose out to PRODUCERS

  11. Perfect Competition is a Model of an Ideal Situation • Helps to understand the major forces at work – market economies often behave ‘as if’ perfect competition were in place • BUT, not a very useful benchmark for policy • If we say ‘every industry which is not perfectly competitive’ must be regulated we have to regulate everything

  12. Practicable Alternatives to Perfect Competition as a Benchmark? • ‘Workable’ competition • the most desirable form of competition selected from those that are practically possible’ – Clark (1940) • but what is that? • ‘Contestable’ markets • Where entry is free and fast and exit involves little cost • Even a single firm cannot exert much market power for fear of entry • A perfect competition type outcome can arise even in situations far from p.c.

  13. All These Approaches Are About Market Structures • But market structure is not the only way to approach the extent of competition • THREE elements • Structure • Conduct • Performance

  14. Conduct and Performance Are Also Key Aspects • Focus on firms’ conduct rather than structure • Cartel arrangements, price fixing. • Aggressive behaviour towards entrants • Focus on performance of firms • Are they making large profits that cannot be attributed to superior efficiency or better products?

  15. Alternative Policy Approaches • ‘rules’ versus ‘discretion • ‘rules’ - certain behaviours or market structures are ‘per se’ illegal • Close to the US approach at one time – it is illegal to monopolize or seek to monopolize (e.g. cartels) and unnecessary to prove harm has been done • ‘discretion’ – certain behaviours or structures may allow damage to the public interest but it is doing the damage that is illegal • The UK approach

  16. Alternative Policy Approaches • Sector-specific versus Comprehensive Competition Laws • Hong Kong has regulations in respect of telecommunications and electricity (the Scheme of Control) but no general competition law • US, UK, Europe have more comprehensive systems

  17. Does Hong Kong Need A Comprehensive Competition Law? • In the traded goods sector • Probably not because HK firms are subject to intense competition amongst themselves and from overseas firms – highly contestable markets – toys, electronics etc • In the domestic market • There are very significant anti-competitive structures and practices

  18. Examples of Anti-competitive structures and practices? • Minimum commissions on brokerages – protects small inefficient firms and reduces the efficiency of capital market • Banking cartel on interest rates – now abandoned but no formal policy to require it. • Park’, Shop v Wellcome (remember Admart?) • Property development – a few large developers and a land sale system biassed in their favour • The European Union expressed concern at the extent to which Hong Kong’s domestic economy is dominated by a small group of interests
