"The price elasticity of demand for low-fat milk in Australia is estimated at -2.07 [Sharma et al 2014)- Do you think the demand for low-fat milk in Australia is price clastic or price inelastic?" In response to the above question, Vu (a 1" year student) writes the following answer. "The price elasticity of demand for low-fat milk is -2.07. It's a negative number, thus, it's lower than 0. Since it's lower than 0, it's definitely lower than 1. Therefore, the demand for low-fat milk in Australia is inelastic." Do you agree or disagree with Vu's answer above? Clearly explain why. Question 4) Harrison owns a dairy farm in Western Victoria. There are about 1,500 dairy farms in the same region. All dairy farms here, Harrison's included, sell milk to at the price of 50 cents per litre. The buyers are Woolworths and Coles, the two biggest supermarket chains in Australia. Last month, Harrison decided to raise his price to $5 cents per litre while his competitors kept the price unchanged. After raising his price, Harrison noticed that his buyers stopped doing business with him. Consequently, Harrison's sales last month crashed to zero. What you can say about the price elasticity of demand for Harrison's milk? Clearly explain. How would you illustrate the demand curve for Harrison's milk on a graph? Note: This question does not focus on the price elasticity of demand for milk overall. It concentrates on the price clasticity of demand for milk supplied by Harrison in particular. Question 5) For each pair of products below, determine which product would have a higher price elasticity of demand (in absolute value), Refer to the list of determinants in the lecture slides, point out which determinant is relevant in each case. a. Drugs for cancer treatment and Lacoste polo shirts b. Petrol (in the short run) and Petrol (in the long run) c. Petrol and Domino's Pizza Pick the following pair of products "Drugs for cancer treatment" and "Lacoste polo shirts"- Draw the demand curve for each of them, then compare. What can you say about the difference in the demand curve between cancer drugs and Lacoste polo shirts? Explain
