## What Is Allocational Efficiency?

Allocational efficiency, also known as allocative efficiency, is a characteristic of an [efficient market](https://www.investopedia.com/terms/m/marketefficiency.asp) where the optimal distribution of goods in an [economy](https://www.investopedia.com/terms/e/economy.asp) meets the needs and wants of society. The goal of allocative efficiency is to ensure that resources are used so that their marginal benefit to society is equal to their marginal cost.

### Key Takeaways

*   Allocational or allocative efficiency is an efficient market whereby all goods and services meet the needs and wants of society.
*   Allocative efficiency ensures that resources are used so that their marginal benefit to society is equal to their marginal cost.
*   An efficient market is always reflected in the [market prices](https://www.investopedia.com/terms/m/market-price.asp) of goods and services.

## Understanding Allocational Efficiency

Allocational efficiency occurs when organizations in the public and [private sectors](https://www.investopedia.com/terms/p/private-sector.asp) spend their resources on projects that will be the most profitable and do the most good for the population, thereby promoting [economic growth](https://www.investopedia.com/terms/e/economicgrowth.asp).

When all of the data for a [market](https://www.investopedia.com/terms/m/market.asp) is accessible, companies can make accurate decisions about what projects might be most profitable, and manufacturers can concentrate on producing products most desired by the general population.

In economics, allocative efficiency materializes at the intersection of the [supply and demand](https://www.investopedia.com/terms/l/law-of-supply-demand.asp) curves. At this [equilibrium](https://www.investopedia.com/terms/e/equilibrium.asp) point, allocative efficiency exists for a firm producing the output for which the price is equal to the marginal cost of production.

> Allocative efficiency measures how an economy uses resources to produce the goods and services people value the most.

## Requirements for Allocational Efficiency

An efficient market is one in which all pertinent data regarding the market and its activities is readily available to all market participants and is always reflected in [market prices](https://www.investopedia.com/terms/m/market-price.asp).

For the market to be efficient, it must be both [informationally efficient](https://www.investopedia.com/terms/s/strongform.asp) and transactionally or [operationally efficient](https://www.investopedia.com/terms/o/operationalefficiency.asp). When a market is informationally efficient, all necessary and pertinent information about the market is readily available to all parties involved. In other words, no parties have an informational advantage over any other.

Meanwhile, all [transaction costs](https://www.investopedia.com/terms/t/transactioncosts.asp) are reasonable and fair when a market is transactionally efficient. This ensures that all transactions are equally executable by all parties and not prohibitively expensive to anyone. If these conditions of fairness are met and the market is efficient, [capital flows](https://www.investopedia.com/terms/c/capital-flows.asp) will go to where they will be the most effective and provide an optimal risk/reward scenario for investors.

## What Is the Difference Between Allocational Efficiency and Distributive Efficiency?

Allocational efficiency is the optimal distribution of goods in an economy that meets the needs and wants of society. Distributive efficiency occurs when goods and services are consumed by those who need them most and focuses on the equitable distribution of resources.

## What Is Allocative Efficiency Important?

Allocative efficiency is important because it ensures that resources are used to satisfy the highest number of wants.

## When Does Allocative Efficiency Happen?

The state of allocative efficiency happens when a firm produces the output for which the price is equal to the marginal cost of production.

## The Bottom Line

Allocational efficiency is the efficient allocation of resources that leads to maximum overall satisfaction in the economy. Allocative efficiency ensures that resources are used so that their marginal benefit to society is equal to their marginal cost. For a firm or producer, allocative efficiency happens when the price of the output is equal to the marginal cost of production.

_Correction—July 31, 2023_: A previous version of this article inaccurately compared allocational efficiency to distributive efficiency, the equitable distribution of resources. The article was edited to clarify that allocation efficiency is the optimal distribution of goods in an economy to meet the needs and wants of society where marginal social cost is equal to the marginal social benefit.
