Contribution to Economics

His most significant contribution in the field of economics includes his contribution to Social Choice Theory, Arrow’s Impossibility Theorem, and General Equilibrium. He had also done research on Endogenous Growth Theory and Economics of Information. His main theories are: [br]

• Arrow’s Impossibility Theorem- the theorem has serious implications on welfare economics and theories of justice. This was extensively worked over by Amartya Sen to the liberal paradox, which lay down that in a status of ‘Minimal Liberty’ Pareto optimality couldn’t be achieved.
• General Equilibrium Theory– the theory proves that a market clearing equilibrium exists. Bu this can be achieved only when there are certain restrictive assumptions made. He also dealt with the other issues relating to this theory like the factor of uncertainty, stability of the equilibrium, and the efficiency of the competitive equilibrium.
• Endogenous Growth Theory– the theory explains the source of technical change, that is a key driver of economic growth. The formulation of this theory triggered a comprehensive research into the endogenous growth theory. Before the theory was been propounded there was no explanation available as to why technical change. Endogenous Growth Theory offered reasons to why the firms innovate.
• He had also developed a paper on the medical aspect of market transaction. He addressed the issue for medical care in the market since there is asymmetry of information in the markets. The sellers usually have more information on the product than the buyers. Therefore they can cheat the buyers. Arrow had analyzed the medical issue pertaining this market asymmetry of information.
