I need help with second part. teacher asked to draw payoff matrix and apply game theory assuming a change in among Woolworths and Coles group

TOPIC: The background for this assignment is to choose a firm in Australia and to use both theory and data in order to identify the market structure under which it operates (part 1). In part 2, you are asked to consider the effect of EITHER one economic condition that changed due to the Covid pandemic OR a government policy that was introduced at the time and how it would have influenced outcomes for your firm. 1. For the firm you have chosen, define the market and identify the key competitors. Analyse the output market characteristics of this firm (e.g. perfect competition, monopoly, oligopoly etc.). Justify your answer using real-time market data (e.g. market share, profits, sales etc.) for this industry in recent years and by linking to the theory and materials covered in the course. Your answer should include the use of the Herfindahl index and market concentration ratio for your justification. 2. The 2020 Covid pandemic has changed much in world markets and seen different types of government response. For the firm you have chosen, provide analysis of the likely effects of one aspect (choose one specific economic issue) of the pandemic OR one policy response made by the Australian government that directly affects your firm. Your answer should discuss aspects such as entry and exit of firms and the implications for the firm's position in the market, and on profitability
