Economic Efficiency Concepts

The production of that particular combination of goods and services that society needs most.

The production of a particular combination of goods and services in the least expensive way.

It involves a complex network of interrelated economic decision-making and activities.

Displays the various amounts of a product that consumers are able and willing to buy at each possible price during a specified period.

If all else is constant, as prices decrease, the quantity demanded increases, and vice versa; when prices rise, demand declines.

Individual demand can be aggregated to get market demand by adding the quantities demanded by all consumers at each of the different possible prices.

These are factors that remain constant in the relationship between price and quantity demanded. A change in any of these will shift the demand curve:

A change in demand is a shift in the entire demand curve:

Quantities of a product that producers are able and willing to produce and offer for sale at each possible price during a specified period.

When the price increases, the quantity supplied increases, and vice versa.

Factors that influence the quantity supplied at each price:

Substitutability: In general, the higher the number of available substitutes, the greater the elasticity of demand.
Share of Income: The higher the price of a good relative to a person's income and budget, the greater the elasticity of demand for that product.
Time: Overall, product demand tends to be more elastic over longer periods.

Demand for necessary goods is often inelastic, while demand for luxury goods tends to be elastic.

In the short term, the amount of individual producers and industry capacity is assumed to be fixed, impacting supply elasticity.
