Human milk is available to feed the baby a few days after the birth. It is made by the mother’s mammary glands from constituents in the maternal blood and its formation is under control of prolactin and oxytocin hormones of the pituitary.The milk contains protein, fat and carbohydrate which fulfill the requirements of baby for heat and energy as well as for growth and repair of tissue.The human mammary gland consists of about 15 separate milk producing systems which are arranged radially around the nipple. ADVERTISEMENTS: The milk is produced deep to the surface in the milk-producing alveoli. These alveoli lead via series of branching ducts to a main milk duct which opens at the nipple. There are thus 15 openings at the nipple, each leading to its own milk…

In the short-run, total quantity of at least one factor of production remains fixed and quantities of other inputs can be changed. Suppose, in a two input framework, capital is the fixed input and OK amount of capital is employed (see figure 9.8).To show the relation between short run Total Cost curve and the long run Total Cost curve we use a fixed set of isocost lines (represented by a2b2, a3b3 and a5b5) and a particular isoquant map (comprising of isoquants I, II, III only) is used.First, consider isocost line ‘a2b2‘. Given this cost constraints and pre­fixed amount of capital OK, maximum amount of labour to be employed is determined by the point of intersection between KK line and isocost a2b2 (i.e., point ‘n’). ADVERTISEMENTS: This point of intersection shows…

Returns to scale refers to a relationship which shows the degree of change in output caused by change in quantities of all inputs in a fixed proportion. The concept of returns to scale is a long-run concept, because it refers to a case where all inputs are variable.In this context, it is also important to distinguish returns to scale from returns to a factor. Instead of all factors, when a relationship specifies change in output as a result of a given change in quantity of only one factor of production, while keeping the others unchanged, it is termed as returns to a factor.There are Three Types of Returns to Scale: (a) Increasing Returns to Scale: ADVERTISEMENTS: When all inputs are increased by a given proportion and the output increases by…

Price elasticity of demand may be of five types, viz, perfectly elastic demand, perfectly inelastic demand, unitary elastic demand, Relatively less elastic demand and Relatively more elastic demand. (a) Perfectly elastic demand: Perfectly elastic demand refers to a situation when due to a very insignificant or small change in price the quantity demanded changes infinitely. In such a case the demand curve is horizontal and parallel to OX axis. In this case the value of elasticity of demand is infinite (ed = It should be remembered that cases of perfectly elastic demand are very rare in actual life and it is only a theoretical case. ADVERTISEMENTS: In the above diagram DD, is the demand curve which is of horizontal shape. (b) Perfectly inelastic demand: This is a type of elasticity…
