INTERNAL DISECONOMIES

Internal diseconomies on the other  hand can be defined as the disadvantages which a firm undergoes as a result of expansion, resulting in less efficiency and increase in the cost per unit of output as a result of managerial problems.

DISADVANTAGES OF LARGE SCALE PRODUCTION

a. Delay in decision making: As a firm grows in size, decision making process will take longer time.

b. Less personnel relationship between workers and management: As a firm grows in size the rapport and interaction that exists when it was small is no more present.

c. Difficulties In co-ordination and control of staff: When a firm grows in size, it might be very difficult to co-ordinate and control the staffs.

d. Over production and Resource Wastage: One major disadvantage of large scale production is the fact that resources can be wasted in production. This is because goods can be overproduced.

e. Large firms take a long time to change their methods of production or to respond to changes in the market. Time is usually wasted before final decisions are reached.

EXTERNAL ECONOMIES

External economies are cost saving advantages which can be enjoyed only by the firms in the same industry. They are benefits due to localization of industry.

Symbolically written as TP = AP X Q

 

2. AVERAGE PRODUCT (AP): Average product is defined as the output per unit of the variable factor (labour or capital) employed. This is obtained by dividing the total output by the number of labour or capital employed.

RELATIONSHIP BETWEENTOTAL PRODUCT, AVERAGE PRODUCT AND MARGINAL PRODUCT.

The relationship between total products, average product and marginal product can be demonstrated by a graph. Both TP and MP initially rise. The TP curve remains at maximum point when MP is zero. TP declines after MP = 0 and MP afterwards assumes negative values.
