The Australian Government monitors the behaviour of oligopolies to ensure firms are not behaving anti-competitively. One behaviour they are concerned about is collusion. Design and analyse a payoff matrix to explain collusion. Do you think rational firms would collude? Why or why not? Explain the Nash equilibrium and resulting payoffs. Can the firms do better? Does behaviour in real-life differ from the theoretical prediction? What can be used to sustain collusion in the real world?

Feel free to copy/paste the below and fill in the blanks with example numbers:

Sahar is a lecturer of a large class of economics students. Sahar can’t stand being ill and so decides to get a flu vaccination. On the other hand, some of Sahar’s colleagues decide to skip their vaccinations because they are too busy. Do the lecturers’ decisions on whether or not to get vaccinated affect their students and if so how? Describe any market failures that arise from this situation. Describe how the government can address any of these market failures. What are some of the potential downsides to government intervention in this case?

Jo was in the market for a used car when she first moved to Melbourne. She spent many hours walking around at Car City looking for one. She found that the salespeople were overly friendly and asked her lots of questions about her life, which frankly, were none of their business. Why were the salespeople doing this? How do you think this information affected the price of the car? Jo had a budget in mind and ended up paying her top price for a car. What does this mean? How does this outcome affect producer and consumer surplus? What about society as a whole?

Nataliya is a fan of soy yoghurts, but recently she has noticed less soy yoghurts on supermarket shelves, with new alternative products such as almond milk yoghurt appearing in their place. What effect does the entrance of new firms have on the market for almond milk yoghurt? What effect does this have on the market for soy yoghurt? What does this tell us about the cross-price elasticity of demand for soy yoghurts? Do you think soy yoghurt and almond milk yoghurt are substitutes or complements in consumption and why? What effect do the new products have on the own-price elasticity of demand for soy yoghurts?

2) When the price of a certain product is $40, then 25 items can be sold. When the price of the same product costs $20, then 185 items can be sold. On the other hand, when the price of this product is $40, then 200 items will be produced. But when the price of this product is $20, only 100 items will be produced.

a) Find the supply and demand functions for this product (assume for simplicity that the functions are linear).
b) Find the equilibrium price and quantity.
c) Compute the consumer and producer surplus at the equilibrium price.
