A. Define price elasticity of demand. What are the 4 major determinants of
price elasticity of demand and give a short explanation of their impact on elasticity?
B. Define price elasticity of supply. What are the 2 major determinants of
price elasticity of supply?
1. A. Price elasticity of demand is a measure of the degree of responsiveness or sensitive of consumers to a change in price. The first determinant of price elasticity of demand is substituted for the product, which is the more substitutes, the more elastic the demand. Another determinant of price elasticity of demand is the proportion of price relative to income, generally the larger the expenditure relative to one’s budget, the more elastic the demand because buyers notice the change in price more. Another determinant of price elasticity of demand is a luxury or a necessity, which is the less necessary the item, the more elastic the demand. The last determinant of price elasticity of demand is time, which is the longer the time period involved, the more elastic the demand becomes.
B. Price elasticity of supply measures the sellers’ responsiveness to price changes. One determinant of price elasticity of supply is the time period that it takes to adjust production depends on the degree of flexibility, different in different industries. Another determinant of price elasticity of supply is the ease of shifting resources between alternative uses.
2. What information is in a budget line? What information is contained in an indifference curve? What is an indifference map? Where is the point of equilibrium (maximum utility) on the indifference map?
2. A budget line shows all the combinations of any two products that a consumer c...

5. The characteristics of pure competition are very large number of firms, standardized products, no control over price, no obstacles to entry, easy entry and exit, and no non-price competition. The characteristics of monopolistic competition are, many firms, differentiated products, some control over price in a narrow range, relatively easy entry, and considerable non-price competition. The characteristics of oligopoly are few firms, standardized or differentiated products, control over price limited by mutual interdependence considerable control with collusion, many obstacles to entry, and much non-price competition. The characteristics of pure monopoly are one firm only, unique product with no close substitutes, considerable over price, entry is blocked, and mostly public relations advertising.

- In this particular assignment, there are a number of questions that a student must ask as a gate pass to beginning this particular assignment. What is a “trade-off”. What is price elasticity and how does it affect the markets. What is considered as the substitution effect. A trade-off is a compromise given in order for one to gain something else. It’s more of a balance that comes out of giving one desirable but incompatible item for another equally desirable object. Price elasticity on the other hand refers to the responsiveness of the demand of a commodity to changes in price of that particular commodity.... [tags: Supply and demand, Consumer theory]

- question 1 Review Slides 10-12 in your Attend section. Suppose a local coffee shop knows that its elasticity of demand is 0.2. Would you recommend that the coffee shop increases its price by 20%. Why or why not. Since the demand is less than zero, this is fairly inelastic demand. This means that quantity demanded won 't be affected much by changes in price. knowing this to be the case, I would suggest increasing price because while there will be some decrease in quantity demanded, it will be more than offset by the larger profits earned by the quantity demanded remaining....

- The concept of Price Elasticity of Demand (PED) measures the responsiveness of quantity demanded by consumers to a change in product price. It is used by businesses to forecast sales, set the most effective price of goods and determine total revenue (TR) and total expenditure (TE). Similarly, governments also use price elasticity of demand when imposing indirect taxes on goods and setting minimum and maximum prices. Marginal revenue is also determined by the price elasticity of demand. Price elasticity of demand is used to predict the quantity shift in the supply curves and the effect on price for a product, and is usually always negative as it is the relationship between price and quantity...

- 1- What is the price elasticity of demand. How is the price elasticity of demand calculated The price elasticity of demand is a term that is usually use in economic to discuss the price sensitivity. It refers to the relationship between a change in the price of a particular good and a change in its quantity demanded, in other words, the price elasticity of demand is the measure of variable reaction to change in another variable. The supply or the demand of a good or service changes with the price or the consumer’s income.... [tags: Supply and demand, Price elasticity of demand]

- McGuigan, Moyer & Harris (2014) price elasticity of demand measured by the changes that affect at least one-factor price, advertising, promotion, packaging or income levels (p.64). However, my supervisor needs the elasticities for each independent variable using the regression equation above and adding values, P= 500, PX= 600, I= $5,500, A= $10,000, M=5,000. Adding the P, PX, I, A, and M value to the regression table: QD= - 5,200 – 42(500) + 20(600) + 5.2(5,500) + 0.20(10,000) + 0.25(5,000) = 17,650....

- 1. What is the price elasticity of demand. How is the price elasticity of demand calculated. The price elasticity of demand as I understand it is how much demand for an item will change with a given change in the price of an item. To be more precise it is the percent change in demand per unit of time divided by the percent change in price. (Khan, "Price elasticity of demand") While most examples I could find of price elasticity of demand were linear, I do not think they would truly be that way in real life....

- Price elasticity is defined in our text as the change in relationship between a change in the quantity demanded and price. When price elasticity is greater than 1, it’s considered “somewhat elastic” so that when the price increases the revenue decreases. This is due to the quantity being changed so significantly it results in a lost in revenue. In a short period of time, this elasticity may not be detrimental but a wide market change could drive away customers and hurt the company. Cross price elasticity is a measure of changes in quantity demands.... [tags: Supply and demand, Price elasticity of demand]

- Price Elasticity of Demand According to Microeconomics, Price Elasticity of Demand is the responsiveness of the quantity demanded to a change in price, measured by dividing the percentage change in the quantity demanded of a product by the percentage change in the product’s price (Hubbard & O’Brien, 2015). Demand is considered elastic when the quantity demanded for a product increases or decreases in response to price change. Normally, sales increase with price drops and decrease when prices rise....
