3. The following table gives the supply schedule for Purcell Ltd, a UK based rug producer. Price (£) Quantity Supplied (Qs) 10 0 20 15 30 21 40 28 (i) What does the price elasticity of supply (PES) measure? (ii) How is it calculated? Write down the full formulae. (iii) Assume that the current price is £20. Calculate the price elasticity of supply if the price increases to £30 (show all your calculations). (iv) Is supply elastic, unit-elastic, or inelastic? Explain why. (v) What would the slope of the supply curve look like? (Hint: Relatively flat or steep supply curve) Based on your calculation and your analysis, draw the supply curve for Purcell Ltd. (vi) Would you expect the PES of rugs to be different in the short term and the long term? Explain your answer in detail.

Assume gasoline is sold in a competitive market, the equilibrium price is $50 per barrel, and the equilibrium quantity is 1000 barrels. (a) Using the numerical values above, draw a correctly labeled graph of the gasoline market and show each of the following. (i) The equilibrium price (ii) The equilibrium quantity (b) At a price of $40 per barrel, will there be a surplus or a shortage in the market? Explain. (c) Assume new oil wells are discovered. On your graph from part (a), show how this change will affect the equilibrium price and quantity in the market for gasoline. (d) Assume instead there is an increase in the price of gasoline-operated automobiles. How will this change affect the market for gasoline? Explain. (e) If both changes in part (c) and part (d) occurred simultaneously, what will happen to the equilibrium price and quantity of gasoline?

(a) You went to the market to buy groceries. You noticed that the price of the tea increased in the market from April to September. Now that you have a knack for elasticity, you wanted to check something. You asked the customers assistant of the store for some information. The information you collected is mentioned below. Information of Tea Market: Price Quantity April 12 14 September 18 10 Information of Coffee Market: Quantity April 12 September 18 Out of curiosity, you wanted to see the effect of change in price of tea on the quantity demanded for coffee. What would be the cross price elasticity of demand due to the price increase of tea? Do not convert into percentage. Give your answer in 2 decimal places. E.g. If you get XED = 0.253 then submit 0.25 (b) Based on the findings in 6(a), you can comment on the relationship of tea and coffee Tea and coffee are - One word answer (complementary/substitute/neutral) goods
Nile.com, the online bookseller, wants to increase its total revenue. One strategy is to offer a 10% discount on every book it sells. Nile.com knows that its customers can be divided into two distinct groups according to their likely responses to the discount. The accompanying table shows how the two groups respond to the discount. Group A Group B(sales per week) (sales per week) Volume of sales beforethe 10% discount 1.55 million 1.50 million Volume of sales afterthe 10% discount 1.65 million 1.70 million A. Using the midpoint method, calculate the price elasticities of demand for group A and group B. B. Explain how the discount will affect total revenue from each group. C. Suppose Nile.com knows which group each customer belongs to when he or she logs on and can choose whether or not to offer the 10% discount. If Nile.com wants to increase its total revenue, should discounts be offered to group A or to group B, to neither group, or to both groups?

QUESTION 1 a) Suppose you are the supplier of fertilisers and that you are in a position to decide at which price you will offer these products for sale. What would your pricing strategy tend to be if you have determined that the price elasticity of the demand for fertilisers is: i. Greater than one. ii. Equal to one. iii. Smaller than one.
Quantity of A traded 10,000 15,000 Household Income | Price of B $3000 Price of A $1.10 $1.50 $0.90 $2500 $1.20 (i) Determine the price elasticity of demand for A, income elasticity of demand for A and the cross price elasticity of demand between A and B using the mid-point formula. Based on the elasticities, classify A in terms of its price and income elasticities of demand and establish the relationship between product A and product B. Given that the price of product A increases by 5%, household income increases by 3% and the price of product B increases by 2%, explain and compute the effect on the revenue from product A, assume each of the changes occurs separately. (ii) (b) The demand and supply functions of wheat is given as P = 20 – 0.05Q and P = 10 + 0.05Q, respectively. Solve for the equilibrium price and quantity in the wheat market. If the government implement a price floor of $18 per unit of wheat to help the wheat farmer, compute the consumer surplus, the producer surplus…
