IB Economics HL 2.11.8 Government responses to market power Question Bank

N.B. It should be noted that definitions, theory and examples that have already been given in part (a), and then referred to in part (b), should be rewarded.

Answers may include:
- definitions of monopoly power and legislation (anti-monopoly, anti-collusion, merger prevention etc.) and regulation (lower prices and larger quantities for consumers, fair prices for natural monopolies)
- theory of how a monopolist's control of price or output might be reduced by legislation or regulation in the interests of the consumer
- diagram to show a comparison of monopoly and perfect competition; diagram to illustrate price regulation showing monopoly charging a price which is equal to average cost
- examples of legislation, regulation, and also other solutions such as nationalization, privatization and trade liberalization
- synthesis and evaluation (discuss).

Discussions may include: effectiveness of policies against the sources of monopoly power, eg reduction of legal barriers to entry, control of anti-competitive behaviour. Where natural monopoly occurs, restrictive policies might not be in the consumer's interest. Government policies might be rendered less effective by globalization. Government policies might move a market from monopoly towards a market structure which gives rise to allocative efficiency.

Examiners should be aware that candidates may take a different approach which, if appropriate, should be rewarded.

Opinions or conclusions should be presented clearly and should be supported by appropriate examples.
