Equilibrium is a situation in which there is no tendency for change. A market will be in equilibrium when there is no reason for the market price of the product to rise or to fall. This occurs at the price where quantity demanded equals quantity supplied.

Do you ever wonder why the prices for some things seem so high, and for other goods, why they seem to go up and down for no clear reason? In fact you can use economics to help you understand what is happening, and then to make informed choices. As we learn about the factors that influence price, you will be able to return to your questions and make sense of the prices.

## Price elasticity of demand

A good's price elasticity of demand is a measure of how sensitive the quantity demanded of it is to its price. When the price rises, quantity demanded falls for almost any good, but it falls more for some than for others. The price elasticity gives the percentage change in quantity demanded when there is a one percent increase in price, holding everything else constant. If the elasticity is -2, that means a one percent price rise leads to a two percent decline in quantity demanded. Other elasticities measure how the quantity demanded changes with other variables e. Price elasticities are negative except in special cases. If a good is said to have an elasticity of 2, it almost always means that the good has an elasticity of -2 according to the formal definition.

The price elasticity of supply is the measure of the responsiveness in quantity supplied to a change in price for a specific good. In economics, elasticity is a summary measure of how the supply or demand of a particular good is influenced by changes in price. Elasticity is defined as a proportionate change in one variable over the proportionate change in another variable:. There are numerous factors that directly impact the elasticity of supply for a good including stock, time period, availability of substitutes, and spare capacity. The state of these factors for a particular good will determine if the price elasticity of supply is elastic or inelastic in regards to a change in price. Inelastic goods are often described as necessities.

## Study Notes on Elasticity of Demand: Concept, Types and Importance

The elasticity of demand can be categorized into three parts: price elasticity, income elasticity and cross elasticity of demand. The elasticity of demand is a measure of a degree of responsiveness of quantity of a product to the change in its determinants. If the demand is more elastic, then a small change in price will cause a large change in the quantity consumed.

The algebraic approach to equilibrium. The algebraic approach to equilibrium analysis is to solve, simultaneously, the algebraic equations for demand and supply. In the example given above, the demand equation for good X was. To solve simultaneously, one first rewrites either the demand or the supply equation as a function of price.

Let us make an in-depth study of Elasticity of Demand.

#### Price Elasticity of Supply

Сьюзан просунула в щель ногу в туфле Феррагамо и усилила нажим. Дверь подалась. Стратмор сменил положение. Вцепившись в левую створку, он тянул ее на себя, Сьюзан толкала правую створку в противоположном направлении. Через некоторое время им с огромным трудом удалось расширить щель до одного фута. - Не отпускай, - сказал Стратмор, стараясь изо всех сил.

Почему бы не сказать - мы выиграли. Насколько мне известно, ты сотрудник АНБ. - Ненадолго, - буркнул Хейл. - Не зарекайся. - Я серьезно.

Нет. - Может быть, сказала, куда идет.

Не может быть, чтобы Грег Хейл был гарантом затеи Танкадо. Это полный абсурд. Танкадо ни за что не доверился бы Хейлу. - Коммандер, - напомнила Сьюзан, - Хейл однажды уже чуть не угробил нас - с Попрыгунчиком. Танкадо имел основания ему верить.

Ты же сказала, что не колешься. Девушка засмеялась: - Это же чудо-маркер. Я чуть кожу не содрала, пытаясь его стереть. Да и краска вонючая.
