This theory concentrates on the situation when one or more than one optimum situation cannot be satisfied. Richard Lipsey and Kelvin Lancaster showed interest in 1956 that if one optimum condition cannot be satisfied in the model, then the best possible solution involves changing the variables from the values that could be optimal.
Lipsey and Lancaster, in 1956, worked hard on this theory. They gave the following statement about this theory. The general theorem for the second best optimum states if there is introduced in the general equilibrium system, there is a constraint which prevents the attainment of one of the Pareto conditions. The other Pareto conditions still attainable are, in general, no longer desirable.
The primary focus of this theory is on what happens when the optimum conditions are not satisfied in an economic model. Lipsey and Lancaster’s results have important implications for the understanding of not only trade policies but many other government policies as well.
Lipsey and Lancaster said that the theorem of second best has important implications in applied welfare economics. Lipsey and Lancaster also gave the argument that the theory of second best shows the futility of piecemeal welfare economics to apply rules for a Pareto optimum to only one sector of an economy, which may move the economy away from the second-best situation.
For example, an economy consists of a private monopoly, which is a set of competitive firms and publicly owned firms which will be deciding how to price the goods in the public interest, and if the firm behaves in a competitive manner, then it will produce more output compared to monopolized goods then what is required by Pareto and various policymakers give their views that some conditions are worse and some conditions are better and no policy by public owned firms can achieve Pareto optimum situation because due to the presence of monopoly form of market in the economy.
The theory of second best also says that there are so many market failures in the economy, and only some market failures can be corrected, and some are uncorrectable, so actions are being taken to correct market failures of only related sectors with the motive of increasing economic efficiency in the market. If an attempt is being made to correct all the market failures, it will be impossible, and there will be a decline in overall economic efficiency in the market.
In this theory, it is better to let two market imperfections to cancel each other effects rather than putting an effort on one market. Thus, it is optimal from the government’s point of view also that only those markets should be corrected and studied in detail which is related with each other.
Indian economy is a mixed economy, and the problem related to the mixed economy also provides a way for applying the principles of the second-best theory. This can be explained with the help of the following example.
There are two sections in the economy. One section is rigidly controlled by the central authority, while the other section of the economy is virtually uncontrolled. If there is a high degree of control in one section and a complete absence of control from another section, then it would be very difficult to achieve a second-best optimum situation.
Thus, to increase efficiency in the market, it is better to increase the degree of control exercised over the uncontrolled sector or give some relaxation on the degree of control over the controlled sector. If this policy is being adopted in a mixed economy like India, then surely the economy will move in the direction of achieving the second-best optimum position.
