FUNDAMENTAL THEOREMS OF WELFARE ECONOMICS Meaning and
Definition
-
The fundamental theorems of welfare economics refer to a set of two theorems that form the cornerstone of modern economic theory. These theorems provide a framework for understanding and analyzing how a competitive market can lead to an efficient allocation of resources and maximize social welfare.
The first fundamental theorem of welfare economics, also known as the welfare-optimality theorem, states that under certain conditions, a competitive market equilibrium will result in an allocation of resources that is Pareto efficient. Pareto efficiency refers to a situation where it is impossible to make any individual better off without making someone else worse off. In other words, the market equilibrium is optimal in terms of resource allocation.
The second fundamental theorem of welfare economics, also called the welfare-efficiency theorem, considers the case where markets are not perfectly competitive or there are externalities present. It states that, under certain conditions, it is possible to achieve a Pareto efficient allocation of resources through the use of appropriate government intervention, such as taxes or subsidies, and the reallocation of resources.
These fundamental theorems highlight the role of market competition and the existence of property rights in achieving economic efficiency and maximizing social welfare. They serve as a guiding principle for policymakers and economists in evaluating and designing economic policies that aim to improve overall societal well-being.
