  EXCEPTION TO THE LAW OF SUPPLY Exceptional or Abnormal Supply: is the supply pattern which does not abide by the law of supply, and therefore, gives rise to the reverse of the basic law of supply which states that the higher the price, the higher the quantity of commodity that will be supplied by the producer, and vice-versa. An abnormal supply also called a Regressive or Backward Sloping Supply Curve. Shows that at higher price, less quantity will be supplied. That is a negative situation in which a fall in the price of a commodity leads to an expansion of its supply. Causes of abnormal supply are as itemized below: 👉Existence of some fixed assets whose prices increase without a  corresponding increase in its size, eg Land 👉Rising wages of labour where a worker tends increase his leisure time and reduce his productive working hours at high wage rate 👉A producer with a particular target income may go on supplying the market with his commodities even when prices fall. 👉Monopolisti

ELASTICITY OF DEMAND Elasticity is a measure of the responsiveness of quantity demanded or quantity supplied to one of its determinants. Economists usually refer to the coefficient of elasticity as the price elasticity of demand, a measure of how much the quantity demanded of a good responds to a change in the price of that good, computed as the percentage change in the quantity demanded divided by the percentage change in price. Other coefficients of elasticity may relate to 'income elasticity of demand', 'cross-elasticity of demand', What Is Price Elasticity of Demand? Price elasticity of demand is an economic measure of the change in the quantity demanded or purchased of a product in relation to its price change. Expressed mathematically, it is: Price Elasticity of Demand = % Change in Quantity Demanded / % Change in  price. There are different types of price elasticity of demand i.e. 1) perfectly elastic demand, 2) perfectly inelastic demand, 3) relatively elastic d
