4. Consider a market where every firm and every potential entrant has the iden- tical cost function C(q) = 3q³-6q² +6q. (a) Find the firm's inverse supply function. (b) Suppose the market demand function is given by QP (P) = 20-2P. Find the long-run equilibrium price, quantity, and the number of firms. (c) Suppose the demand function suddenly becomes perfectly inelastic at quan- tity Q = 7. Find the long-run equilibrium price, quantity and the number of firms. (d) Suppose the demand becomes perfectly inelastic at quantity Q = 7, and the government decides to collect a per unit tax t = 4 from the producers for every unit of the good they sell. Find the long-run equilibrium price, quantity and the number of firms.

Find the supply equation using the given information. (Let x be the number of items.) At a price of $1400 a supplier will supply 170 items. If the price decreases by $100, then the supplier will supply 20 fewer items. S(x) =

If the demand function for a company is given by the equation p= -(16+4)q+(16+16000), and the supply is given by the equation q=(16+550)-p. Find the equilibrium point.
New Zealand possums produce the highest quality fur, due to the large pelts per body size. Demand for New Zealand possums’ products has risen dramatically. This is partly a result of the conservation benefits of harvesting New Zealand possums. This has made the product seem more environment friendly than other fur products and boosted sales to concerned consumers. Assume that the possums market satisfies all the attributes of a competitive market. Further assume that high grade possum furs are the most expensive input into the possum fur production function. 1. Use a graph of the market for possum fur to demonstrate the effect of its environmentally friendly status on the market equilibrium. 2. Graph the reaction of an individual incumbent firm to the increase in market demand. In your graph, identify the firm’s revenue and cost structures. 3. What would you predict would happen to long-run industry supply if the price of possum fur increased as possum culling increased their…
The supply function for a product is 2p − q − 60 = 0, while the demand function for the same product is (p + 20)(q + 10) = 8100. Find the market equilibrium point.

(a) At price 150, what is the price elasticity of dog breeders’ demand for electric dog polishers? (it's a negative number) (b) At price 15, what is the price elasticity of pet owner’ demand for electric dog polishers? (it's a negative number) (c) Find a nonzero price at which there is positive total demand for dog polishers and at which there is a kink in the demand curve. $_____. What is the market demand function for prices below the kink. What is the market demand function for prices above the kink? ______ + P
Consider a competitive market for red lentils with 100 identical farmers in Horsham Victoria, a competitive market price of $5 and the following MC for each farmer: MC = $0.05Q Also consider the following market demand function: QD a) Calculate the optimal level of production (in tonnes) for each farmer (show workings) = = 1000 - 40P b) Assuming 100 lentil farmers of equal size how many tonnes of lentils in total will be supplied in the entire market? (show all workings) c) Consider that the government now imposes a 25% tax on producers, calculate i) the new equilibrium level of output for each firm (hint - think about how this affects each farmer's marginal cost), and ii) new total supply in the entire market (show all workings)
Each firm in a perfectly competetive market has a long-run total cost of LRTC = 100g – 10q + 100. The market demand is Q* = 2150 – 5P. At the long-run equilibrium price, how many firms will there be in the market? (а) 500 (b) 1,000 (c) 1,200 (d) 2,000 (e) 2,400
