Chapter 2 the Basics of Supply and Demand

            One reason that could have led the ice cream sale to fluctuate could have been due to Price of Related goods. For example, frozen yogurt is a substitute for ice cream, so when the price increases, more ice cream is demanded. However, hot fudge is a compliment for ice cream, therefore when its price goes up, less ice cream is demanded. Second reason leading for the ice cream sale to fluctuate could be due to income. For normal goods, the higher your income, the more you buy. For inferior goods, the higher your income, the less you buy. Taste is another factor. When taste changes, the quantity demands change.  For example, our taste for ice cream might depend on the weather. Expectations are also an important factor.  Expectations about future income or prices affect the quantity demanded today.

4) For each article describe causes of changed price and the effects of the changed price.

Elasticity of demand is the relationship between the demands for a product with respect to its price. Generally, when the demand for a product is high, the price of the product decreases. When demand decreases, prices tend to climb. Products that exhibit the characteristics of elasticity of demand are usually cars, appliances and other luxury items. Items such as clothing, medicine and food are considered to be necessities. Essential items usually possess inelasticity of demand. When this occurs prices do not change significantly.

3. The price elasticity of demand increases with the length of the period considered simply because ( )

d. Calculate the price elasticity of demand in each market and discuss these in relation to the prices to be charged in each market.

* From the scenario for Katrina’s Candies, examine the key factors affecting the demand for and the supply of a good in general and Katrina’s Candies specifically. Distinguish between a change in demand and a change in the quantity demanded (movement along the demand curve).

If the product coast a large percentage of the average consumer’s income, people will pay more attention to sale prices because they may be afraid of a fact that if the price keeps rising, they can’t afford it because it is expensive and costs most of their income. It is common that we spend more than $200 on one pair of Nike shoes, which are quite expensive. However, the price of bread is low. Furthermore, one pair of Nike shoes costs more percentage of clients’ income than a piece of bread. If the price declines, people would like to buy more Nike shoes because they can’t afford it in normal time. However, people won’t buy too much bread than before because the bread may go rancid quickly. So people are more sensitive to the price of Nike shoes. As a consequence, all Nike shoes sold in Canada have more elasticity than all bread sold in Canada.

Apple juice and orange juice are substitutes for consumers, so the fall in the price of apple juice decreases the demand for orange juice. The demand curve for orange juice shifts leftward. The increase in the wage rate paid to orange grove workers raises the cost of producing orange juice. The supply of orange juice decreases and the supply curve of orange juice shifts leftward. The net effect of these events decreases the equilibrium quantity but has an undetermined effect on equilibrium price. If supply decreases by more than the demand, the shift in the

2.) Which curve(s) change and based on the lists in the text of what causes demand and supply to shift what are the causes of theses shifts? D1 changed moving leftward indicating a decrease in demand due to a technological change: a technological setback causes a decrease. This causes price to go down as well as the demand is lower.

This causes the price and the quantity move in opposite directions in a supply curve shift. Also, if the quantity supplied decreases at any given price the opposite will happen.

Elasticity : rising or falling price lead changes in quantity of demand, and the quantity of supply and this so-called elasticity

2. The quantity of peanuts supplied increased from 40 tons per week to 60 tons per week when the price of peanuts increased from $4 per ton to
$5 per ton. The price elasticity of supply for peanuts over this price range is

Elasticity is a measure of the responsiveness of demand to changes in the price of a good or service. In the case of Steam Scot, when the price rises from 4 to 5, demand falls from 60,000 to 40,000 units. The original equilibrium market price of 4 pounds resulted in demand of 60,000 units and this generated revenue of 240,000 pounds. When the prices increased to 5 pounds the resulting demand is 40,000 units, and this generates total revenue of 200,000 pounds. When market price changes from 4 pounds to 5 pounds 40,000 pounds of revenue are lost in this indicates an elastic price elasticity of demand.

D) slope upward. Answer: C 2) An increase in the price of pork will lead to A) a movement up along the demand curve. B) a movement down along the demand curve.

B) a movement upward along the demand curve for plasma TVs. C) a rightward shift of the supply curve for plasma TVs. D) no change of the demand curve for plasma TVs. Answer:

Elasticity of demand represented as “Ed” is defined as a “measure of the response of a consumer to a change in price on the quantity demanded of a good” (McConnell, 2012). Determinants for elasticity of demand would include the substitutability of a good, proportion of a consumer 's income spent on a good, the nature of the necessity of a good and the time a purchase is under consideration by the consumer. Furthermore, elasticity of demand is calculated with this formula:
