demand

Examples of demand in the following topics:

• Demand Schedules and Demand Curves

  • A demand curve depicts the price and quantity combinations listed in a demand schedule.
  • The demand curve of an individual agent can be combined with that of other economic agents to depict a market or aggregate demand curve.
  • Using a demand schedule, the quantity demanded per each individual can be summed by price, resulting in an aggregate demand schedule that provides the total demanded specific to a given price level.
  • In this manner, the demand curve for all consumers together follows from the demand curve of every individual consumer.
  • It is derived from a demand schedule, which is the table view of the price and quantity pairs that comprise the demand curve.

• Market Demand

  • The demand schedule is depicted graphically as the demand curve.
  • The demand curve is shaped by the law of demand.
  • The graphical representation of a market demand schedule is called the market demand curve.
  • As noted, both individual demand curves and market demand are typically expressed as downward shaping curves.
  • The demand curve is the graphical depiction of the demand schedule.

• Income Elasticity of Demand

  • The income elasticity of demand measures the responsiveness of the demand for a good or service to a change in income.
  • The income elasticity of demand (YED) measures the responsiveness of demand for a good to a change in the income of the people demanding that good, ceteris paribus.
  • In contrast, if a rise in income leads to a decrease in demand, the good or service has a negative income elasticity of demand.
  • Negative income elasticity of demand (YED<0): An increase in income is accompanied by a decrease in the quantity demanded.
  • Income elasticity of demand measures the percentage change in quantity demanded as income changes.

• Shifts in the Money Demand Curve

  • A shift in the money demand curve occurs when there is a change in any non-price determinant of demand, resulting in a new demand curve.
  • The real demand for money is defined as the nominal amount of money demanded divided by the price level.
  • A demand curve is used to graph and analyze the demand for money.
  • The shift of the money demand curve occurs when there is a change in any non-price determinant of demand, resulting in a new demand curve.
  • Likewise, when the demand curve shifts to the left, it shows a decrease in the demand for money.

• Shifts in investment due to shocks

  • Positive and negative demand shocks directly impact investment; increases in demand encourage higher investment while less demand lowers investment.
  • In economics, a demand shock is a sudden event that increases or decreases the demand for goods or services.
  • A positive demand shock increases the demand (not the quantity demanded), while a negative demand shock decreases the demand.
  • The graph shows the demand curve.
  • When there is a positive demand shock, the demand for goods increases causing the demand curve to shift to the right.

• Defining Price Elasticity of Demand

  • The price elasticity of demand (PED) measures the change in demand for a good in response to a change in price.
  • The price elasticity of demand (PED) is a measure that captures the responsiveness of a good's quantity demanded to a change in its price.
  • The law of demand states that there is an inverse relationship between price and demand for a good.
  • When demand is perfectly inelastic, quantity demanded for a good does not change in response to a change in price.
  • When the demand for a good is perfectly elastic, any increase in the price will cause the demand to drop to zero.

• Interpretations of Price Elasticity of Demand

  • The price elasticity of demand (PED) explains how much changes in price affect changes in quantity demanded.
  • The price elasticity of demand (PED) is a measure of the responsiveness of the quantity demanded of a good to a change in its price.
  • When PED is greater than one, demand is elastic.
  • The second is perfectly inelastic demand.
  • The price elasticity of demand for a good has different values at different points on the demand curve.

• Reasons for and Consequences of Shift in Aggregate Demand

  • A short-run shift in aggregate demand can change the equilibrium price and output level.
  • In economics, aggregate demand is the total demand for final goods and services at a given time and price level.
  • The aggregate supply-aggregate demand model uses the theory of supply and demand in order to find a macroeconomic equilibrium.
  • The aggregate demand curve shifts to the right as a result of monetary expansion.
  • The Aggregate Supply-Aggregate Demand Model shows how equilibrium is determined by supply and demand.

• Macroeconomic Equilibrium

  • There are four basic laws of supply and demand.
  • The laws impact both supply and demand in the long-run.
  • If quantity demand decreases and supply remains unchanged, a surplus occurs, leading to a lower price until the quantity demanded is pushed back to equilibrium.
  • Aggregate demand is the total demand for final goods and services in an economy at a given time and price level.
  • When the demand increases the aggregate demand curve shifts to the right.

• Applications of Elasticities

  • For elastic demand, when the price of a product increases the demand goes down.
  • When the price decreases the demand goes up.
  • For inelastic demand, the overall supply and demand of a product is not substantially impacted by an increase in price.
  • An elastic demand curve shows that an increase in the supply or demand of a product is significantly impacted by a change in the price .
  • For elastic demand, when there is an outward shift in supply, prices fall which causes a large increase in quantity demanded.
