question: please explain in deep summarise work in economics topics

(@) (1) State and explain FOUR factors which affect a consumer's demand schedule, other than the price of a good itself. (ii) Explain the economic rationale for assuming that a person's demand curve for a normal good slopes downward. (b) For something to be considered an economic good, it must possess certain characteristics. State and explain THREE of these characteristics. (c) A consumer spends all income on two goods, Good A and Good B. Both goods are normal goods but they are not complementary goods. The price of Good A is reduced and the price of Good B remains unchanged. The consumer continues to spend all income on the two goods. Distinguish between the substitution effect and the income effect of the price reduction in Good A.1. (a) Outline THREE key features of an oligopolistic market and state ONE example of an oligopolistic market in Ireland. (b) With the aid of ONE clearly labelled diagram: (i) Explain the shape of the demand curve facing a firm in oligopoly. (i) Explain the relationship between this demand curve and the firm's marginal revenue curve. (Hii) Explain the long run equilibrium position of this firm. (c) Explain THREE methods by which firms in oligopolistic markets may collude. 2. (a) Define (1) price elasticity of demand and (ii) cross elasticity of demand. In each case, state the formula by which it is measured. (b) When the price of Good X is (27, the quantity demanded of Good Y is 1,200 units. When the price of Good X falls to (23 (the price of Good Y unchanged) the quantity demanded of Good Y falls to 800 units. (i) Using the cross elasticity of demand formula, calculate the cross elasticity of demand for Good Y. Show all your workings. (ii) Is Good Y a substitute for or complement to Good X? Explain your choice. (25 marks) (c) A firm has the following price elasticities of demand for two goods, Good X and Good Y: Good X ..... 2.0 Good Y ..... 0.5 What changes, if any, should the firm make in the selling price of each of the goods to increase overall revenue.
