SS 2 Economics (1st, 2nd & 3rd Term)

RATIONING This is a prevailing economic situation of scarcity  of essential commodities in the market in which consumers are allowed to have access to these commodities at specified quantities and at regulated period of times. The scarcity of these essential commodities in the market may be man – made, and which is known as artificial […]

PRICE CONTROL POLICY This is defined as a process by which the government or its agency fixes the price of essential commodities. That is, it is a situation where the government uses the instrument of law to fix the price of certain commodities.  It can be in the form of maximum or minimum price control.

Cross Elasticity of Demand is the degree of responsiveness of quantity demanded of commodity X to a little change in the price of commodity Y.  Cross elasticity of  demand is applicable mainly to goods that are close substitute as well as complementary goods.   For example the demand for Milo will increase as a result of

Income elasticity of demand is the degree of responsiveness of quantity  demanded of a commodity to a little change in consumer’s income. That is, it measures how changes in income of consumers will affect the quantity of commodities demanded by such consumers. Mathematically, income elasticity of demand is expressed as: % change in Quantity Demanded

Elasticity of supply can be defined as the degree of responsiveness of change in quantity supplied as a result of change in price.  Elasticity of supply measures the extent to which the quantity of a commodity supplied by a producer changes as a result of a little change in the price of the commodity.  

DEFINITION OF ELASTICITY OF DEMAND Elasticity of demand may be defined as the degree of responsiveness of demand as changes in price, income, prices of other commodities etc.   Types of Elasticity of Demand Price elasticity of demand Income elasticity of demand Cross elasticity of demand   EVALUATION Define Elasticity. State three types of Elasticity

CHANGE IN QUANTITY DEMANDED A change in quantity demanded, is otherwise known as movement along a particular demand curve that is only influenced by price. When there is a change in the quantity demanded, the demand curve does not shift. This is because the price of the commodity is the only cause of a change

THEORY OF CONSUMER BEHAVIOUR The theory of consumer behaviour is also known as the theory of household behaviour.  It is primarily concerned with how the consumer or household tries to satisfy his/her wants by dividing his/her limited amount of income between the various commodities that give him equal amount of satisfaction.   WHAT IS UTILITY?

MEASURES OF DISPERSION This also known as measures of spread or variation describes how the data given in any distribution are spread about the ‘Mean’, or the overall spread of the data. These measures are the range, mean – deviation, standard deviation, variance, coefficient of variation, etc.   The Range: The range of a data

MEASURES OF CENTRAL TENDENCY These are the values which show the degree to which a given data or any given set of values will converge toward the central point of the data. Measures of central tendency, also called measures of location, is the statistical information that gives the middle or centre or average of a
