a) Explain verbally and digramatically why Christmas trees are cheaply sold on Christmas Eve (compared to their intial price) by considering both demand and supply. (b) Assuming zero disposal costs, why is the correct profit maximising price to charge for the unsold trees on Christmas Eve the one at which the elasticity of demand is equal to -1? Illustrate using a diagram. Would the price be lower still if there were some disposal costs that the seller would face to dispose of the unsold trees?

- (Calculating Price Elasticity of Demand) Suppose that 50 units of a good are demanded at a price of Si per unit. A reduction in price to $0.20 results in an increase in quantity demanded to 70 units. Using the midpoint formula, show that these data yield a price elasticity of 0.25. By what percentage would a 10 percent rise in the price reduce the quantity demanded, assuming price elasticity remains constant along the demand curve?4. There is no demand for a certain make of one-time use camera when the unit price is $ 12. However, when the unit price is $ 8, the quantity demanded is 8000/week. The supplier will not market any cameras if the unit price is $ 2 or lower. At $ 4/camera, however, the manufacturer will make available 5000 cameras/week. Given that both the supply and demand equations are linear: (a) Determine the associated linear demand function (b) Determine the linear supply function. (c) At what price should the camera be sold so that there is neither a surplus nor a shortage?PRICE (Dollars per unit) 350+ 225 175) 50 0 Region Between Y and Z Between W and X Between X and Y Z True False X 28 36 QUANTITY (Units) For each of the regions listed in the following table, use the midpoint method to identify if the demand for this good is elastic, (approximately) unit elastic, or inelastic.

The before-tax total cost of retailing petrol is $1.20 per litre. Assume that 100% of the tax is always passed through to consumers. After the increase in taxes, the quantity of petrol sold falls from 3,000,000 litres a day to 2,800,000 litres a day. Calculate the price elasticity of demand for petrol using the mid-point formula, based on the change in price due to the tax. Use three decimal places in your calculations. What are the implications for policymakers who want to raise revenue, when considering raising taxes on petrol?
