Suppose that the tourism market in Australia is perfectly competitive (i.e., many tourism companies). The pandemic of Covid-19 lowers tourism demand in Australia.

Using appropriate DIAGRAMS to answer:

(a). By using industry's Demand and Supply curves, please examine the impacts of Covid-19 on the

Australian tourism market in the short run and long run.

(b). By using firm's price and cost curves, please examine the short-run and long-run impacts of

Covid-19 on a representative tourism company in Australia.

Please I need to know what the diagrams would look like with explanation. Thank you.
