Outcomes and performance criteria
Outcome 1
Analyse the behaviour of the short-run costs of production using economic principles.
Range economic costs includes – accounting costs, opportunity costs;
short-run costs includes – variable cost, fixed cost, average total cost, marginal cost.
Performance criteria
1.1 The analysis is illustrated by means of a graphical depiction consistent with cost data.
1.2 The analysis accounts for the inter relationships between output and costs in terms of the law of diminishing returns and production capacity.
Outcome 2
Analyse the relationship between cost and production in the long-run using economic principles.
Performance criteria
2.1 The analysis establishes the shape of the long-run average costs curve, consistent with least-cost production decisions.
Range one of – graphical, numerical economies of scale, diseconomies of scale.
Outcome 3
Explain the behaviour of firms operating under perfect competition.
Performance criteria
3.1 The explanation highlights the features of a perfectly competitive market structure.
Range number of firms, product differentiation, control over price, extent of market information, freedom of entry.
3.2 The explanation determines the short-run equilibrium of the firm consistent with the profit maximisation condition.
Range one of – graphical, numerical, algebraic;
one of – profit – normal, subnormal, supernormal.
3.3 The explanation predicts the long-run profit outcomes for the firm consistent with profit maximising behaviour and industry equilibrium price movements.
Range one of – short-run supernormal profit resulting in long-run normal profit, short-run subnormal profit resulting in long-run normal profit.
Outcome 4
Explain the behaviour of firms operating under monopoly market structure.
Performance criteria
4.1 The explanation highlights the features of a monopoly market structure.
Range number of firms, product differentiation, control over price, extent of market information, freedom of entry.
4.2 The explanation determines short-run and long-run equilibrium of the firm, consistent with the profit maximisation objective.
Range one of – graphical, numerical, algebraic;
one of – profit – normal, subnormal, supernormal.
4.3 The explanation assesses the behaviour of monopoly in terms of its market power.
Range market power – barriers to entry, product differentiation, price discrimination.
Outcome 5
Explain the behaviour of firms operating under a monopolistically competitive market structure.
Performance criteria
5.1 The explanation highlights the features of a monopolistically competitive market structure.
Range number of firms, product differentiation, control over price, extent of market information, freedom of entry.
5.2 The explanation determines short-run and long-run equilibrium of the firm, consistent with the profit maximisation objective.
Range one of – graphical, numerical, algebraic;
one of – profit – normal, subnormal, supernormal.
Outcome 6
Explain the behaviour of firms operating under an oligopolistic market structure.
Performance criteria
6.1 The explanation highlights the features of an oligopolistic market structure.
Range number of firms, product differentiation, control over price, extent of market information, freedom of entry.
6.2 Oligopoly behaviour is explained in terms of the market structure.
Range price – interdependence, price leadership, price followership, kinked demand curve model;
behaviour – advertising, output, product differentiation.
Outcome 7
Evaluate the performance of firms under different market structures.
Performance criteria
7.1 The evaluation assesses the performance of market structures.
Range two of – perfect competition, monopoly, oligopoly, monopolistic competition;
two of – allocative efficiency, productive efficiency, quantity produced, price, research and development, innovation, consumer choice.
7.2 The evaluation describes a contemporary example of government regulation restricting the market power of firms.
