(i) Explain the Equi-Marginal Principle of consumer behaviour. i) State and explain three other economic assumptions used to analyse consumer behaviour. A manufacturer of three different products calculates the price elasticity of demand (PED) for each product as follows: Product A: -2.8 Product B: -1.0 Product C: -0.5 The manufacturer wishes to maximise its revenues. Explain in respect of each of these products, what change, if any, the manufacturer should make in the prices currently being charged to enable it to achieve its aim. Illustrate your answers with the aid of a demand curve for each product. You are given the following information about certain products: Cross Elasticity of Demand between Product X & Product A = -0.8 Cross Elasticity of Demand between Product X & Product B = +3.2 Cross Elasticity of Demand between Product X & Product C= -1.6 Cross Elasticity of Demand between Product X & Product D = +0.5 (1) Which of the products above are substitutes for Product X? Explain your answer. (ii) Which product is the closer complement to Product X? Explain your answer (i) Explain the reason for the shape of the demand curve of an individual firm in perfec competition. (ii) Outline two advantages of perfect competition. (i) Explain, with the aid of a labelled diagram, the equilibrium position of a firm in short run perfect competition. (ii) With the aid of labelled diagrams, explain the impact which the entry of new firms would have on the market and on the equilibrium position of the firm. Contrast the characteristics of perfect competition with monopoly under the following headings: Barriers to entry; Profits in the long run; Economies of scale; . . Price discrimination.(i) Explain the following terms in relation to a factor of production: . Supply Price; . Transfer Earnings. (ii) Explain the concept Economic Rent and outline two circumstances under which a factor of production can earn it. (i) State and explain the economic reasons why entrepreneurship is important to the development of the Irish economy. (ii) State and explain three means by which the Irish Government could encourage entrepreneurship in Ireland. There are 200,000 small firms in Ireland employing 655,000 people'. (Small Firms Association, December 2011) Discuss the reasons why small firms survive in the Irish economy. With the aid of two clearly labelled diagrams, explain the relationship between: (i) the short run average cost curve and long run average cost curve. (ii) the short run average cost curve and marginal cost curve. Discuss the economic factors which should be considered by a firm when deciding where to locate its operations. Ocean Blue Ltd produces two boats weekly and incurs the following weekly costs: . Rent: (1,200 Raw materials: (2,000 Labour: E1,600 . . Normal profit: 61,000 What is the minimum price at which each boat can be sold if production is to continue: (i) in the short run? (ii) in the long run? Explain your answers in each case
