In economics, the field of public finance deals with three broad areas: macroeconomic stabilization, the distribution of income and wealth, and the allocation of resources. . Much of the study of the allocation of resources is devoted to finding the conditions under which particular mechanisms of resource allocation lead to Pareto efficient outcomes, in which no party's situation can be ...
In order to fully understand market failure, one must first comprehend market success, which is defined as the ability of a set of idealized competitive markets to achieve an equilibrium allocation of resources that is Pareto-optimal in terms of resource allocation.
Allocation efficiency occurs when there is an optimal distribution of goods and services, considering consumer's preference. When the price equals marginal cost of production, the allocation efficiency is at the output level. This is because the optimal distribution is achieved when the marginal utility of good equals the marginal cost.
Because productive resources are scarce, the resources must be allocated to various industries in just the right amounts, otherwise too much or too little output gets produced. [2] When drawing diagrams for businesses , allocative efficiency is satisfied if output is produced at the point where marginal cost is equal to average revenue.
Therefore, the establishment of the property rights system is the basis for optimizing resource allocation (to Pareto optimal). When faced with an externality, the same efficient outcome can be reached without any government intervention as long as the following assumptions hold: Property rights must be clearly defined
Let Xk be an allocation in the k-replicated economy where all copies of the same agent receive the same bundle as the original agent in X. The allocation X is called sigma-optimal if for every k, the allocation Xk is Pareto-optimal. Lemma: [7]: 528 An allocation is sigma-optimal, if-and-only-if it is a competitive equilibrium.
Each point on a social utility frontier represents an efficient allocation of an economy's resources; that is, it is a Pareto optimum in factor allocation, in production, in consumption, and in the interaction of production and consumption (supply and demand). In the diagram below, the curve MN is a social utility frontier.
A firm is said to be productively efficieducing at the lowest point on the average cost curve. This is where marginal cost meets average cost. Allocative efficiency takes into account the preferences of the consumers and the efficient allocation of resources. Graphically this point is reached when price is equal to marginal cost.
