Table 1

(a.ii)

Assuming that this catering market is in long-run equilibrium, sketch a diagram in which the profit-maximizing level of output for a firm in this market is shown.

Markscheme

For a negatively sloped D (AR) tangential to AC [1]

For the point of tangency being vertically above the profit maximizing output where MR and MC intersect [1]

A response with missing or incorrect labels or without MC intersecting minimum AC may be awarded a maximum of [1]

The vertical axis may be labelled Cost (C), Price (P) or Revenue (R). The horizontal axis may be labelled Quantity (Q) or Output. AC may be labelled ATC. A title is not necessary.

Examiners report

This part was generally done poorly. A significant number of candidates did not identify the market structure as one of monopolistic competition. The phrase "prepares a variety of different meals" indicated that products were not identical. Furthermore, candidates generally found difficulty in sketching an appropriate diagram with the ATC curve tangential to the AD curve at a level of output where MR = MC.
