Following the increase in price of a 250g bag of coffee from £2.35 to £2.65 in a local supermarket, weekly sales of tea increase from 8.5 kg to 11.5 kg. From this we can conclude that: a) The price elasticity of demand for tea is -2.76, so that consumer’ demand for tea is highly elastic. b) The income elasticity of demand among consumers is 10, confirming that tea, but not coffee, is a luxury good. c) The cross-price elasticity of demand is 2.5, confirming that tea is a substitute for coffee. d) The price elasticity of demand for coffee is -0.4, so that the demand for coffee is price inelastic.
You are an analyst. Your friend started a new business of selling masks. She knows that you have adequate knowledge of economics and business, and hence, asked for your help in making some important business decisions. From the data obtained from her, you computed the Price Elasticity of Demand (PED) of Masks, and found PED in February was 1.8 (absolute value), and PED of Masks in April was 0.7 (absolute value). (a) What type of good mask is in the month of April in terms of elasticity? (b) The market price of the mask in June was 10 taka per unit and revenue earned in June was 150 taka. How many masks were sold in June? (c) In 2(b), you found the quantity demanded masks in June. You received the data for August and observed that the price in August was 25 per unit and the quantity demanded of masks in August is 7. Calculate the Price Elasticity of Demand (PED) for masks from June to August.

a new study suggests that eating wild salmon reduces your chances of developing heart disease. At the same time, the government adopts a new regulation that increases the cost of catching wild salmon. Based on these changes we would expect the equilibrium quantity of the wild salmon sold to. increase decrease remain unchanged it is impossible to say
The Globe and Mail (December 16, 1997) reported that milk consumption declined following price increases: “Since the early 1980s, the price of milk in Canada has increased 22 per cent. As prices rose, the demand for milk fell off. Total [consumption] of milk on a per capita basis dropped . . . to 2.62 hectolitres in 1995 from 2.92 hectolitres in 1986.” Use these data to estimate the price elasticity of demand for milk. (1.5marks) 0.49 milk is inelastic According to your estimate, what happens to milk producers’ revenue when the price of milk rises? (1 mark) When the price of milk rises milk producers revenue drop because the demand for milk dropped Why might your estimate of the elasticity be unreliable? (Hint: Notice that The Globe and Mail is careless about the distinction between demand and quantity demanded.) (1 mark)

Koeler et al. (2004) estimate that the U.S. Tobacco Settiement between major tobacco companies and 46 states caused the price of cigarettes to jump by 45e per pack (21%) and overall per capita cigarete consumption to fal by 8.3%.
