A Dead Wight Loss is a permanent loss of well being of the society. It occurs when equilibrium for a commodity is not Pareto Optimal. Pareto Efficiency is a broad concept with a broad application in economics. A change that can make at least one individual better off without making any other individual worst off is Pareto Efficiency. A situation is Pareto Optimum when no further improvement is needed. Many natural wastes in a system for e.g., leakage in water pipe are equal to Dead Weight Loss. Monopoly leads to lack of economic competition; it also creates Dead Weight Loss. In loss of benefits due to indirect tax there is some amount of Dead Weight Loss or excess burden which the society has to bear. In case of relatively elastic commodities the Dead weight Loss is more than the revenue earned by the government though the indirect tax. This is the reason why inelastic commodities are taxed more than elastic commodities.
Producer’s Surplus
Producer’s Surplus exists when actual price exceeds the minimum price that the seller is ready to accept. Let us take an example. If Sam considers as CD worth Rs. 50 and Ram, who owns it values the CD for Rs. 10 then, if Ram sells the CD for Rs. 30, Sam, who willing to pay Rs. 50 maximum for the CD actually got it for Rs. 30. Sam is now enjoying a consumer surplus of Rs. 20 and Ram who was ready to accept the minimum price of Rs 10 for the CD, sold it for Rs. 30 and enjoys the producer’s surplus of Rs. 20.
Producer’s surplus may appear to be a profit, but it takes different forms. To understand how Produer’s surplus takes different forms. Let us see one example.
Suppose the price of wheat is Rs. 35 per kg for many years, but now it has increased to Rs. 45 per kg. This increase in price of wheat draws more land under wheat cultivation. Now, farmers, who are cultivating and selling wheat, are enjoying Producer’s surplus of Rs. 10 which they are having due to increase in the price.
