Chapter 3 supply and demand

Crazy for Coffee Starbucks Coffee Company revolutionized the coffee-drinking habits of millions of Americans. Fifteen years later it had grown into a chain of four stores in the Seattle area. But over the last decade the price of coffee beans has been quite volatile. Excessive rain and labor strikes in coffee-growing areas of South America had reduced the supply of coffee, leading to a rise in its price.

Graphical representations[ edit ] Although it is normal to regard the quantity demanded and the quantity supplied as functions of the price of the goods, the standard graphical representation, usually attributed to Alfred Marshallhas price on the vertical axis and quantity on the horizontal axis.

Since determinants of supply and demand other than the price of the goods in question are not explicitly represented in the supply-demand diagram, changes in the values of these variables are represented by moving the supply and demand curves often described as "shifts" in the curves.

By contrast, responses to changes in the price of the good are represented as movements along unchanged supply and demand curves. Supply schedule[ edit ] A supply schedule is a table that shows the relationship between the price of a good and the quantity supplied.

Under the assumption of perfect competitionsupply is determined by marginal cost. That is, firms will produce additional output while the Chapter 3 supply and demand of producing an extra unit of output is less than the price they would receive.

A hike in the cost of raw goods would decrease supply, shifting costs up, while a discount would increase supply, shifting costs down and hurting producers as producer surplus decreases. By its very nature, conceptualizing a supply curve requires the firm to be a perfect competitor i.

This is true because each point on the supply curve is the answer to the question "If this firm is faced with this potential price, how much output will it be able to and willing to sell? Economists distinguish between the supply curve of an individual firm and between the market supply curve.

The market supply curve is obtained by summing the quantities supplied by all suppliers at each potential price. Economists also distinguish the short-run market supply curve from the long-run market supply curve.

In this context, two things are assumed constant by definition of the short run: In the long run, firms have a chance to adjust their holdings of physical capital, enabling them to better adjust their quantity supplied at any given price.

Furthermore, in the long run potential competitors can enter or exit the industry in response to market conditions. For both of these reasons, long-run market supply curves are generally flatter than their short-run counterparts. The determinants of supply are: Production costs are the cost of the inputs; primarily labor, capital, energy and materials.

Following the law of demandthe demand curve is almost always represented as downward-sloping, meaning that as price decreases, consumers will buy more of the good. The demand schedule is defined as the willingness and ability of a consumer to purchase a given product in a given frame of time.

It is aforementioned that the demand curve is generally downward-sloping, and there may exist rare examples of goods that have upward-sloping demand curves.

Two different hypothetical types of goods with upward-sloping demand curves are Giffen goods an inferior but staple good and Veblen goods goods made more fashionable by a higher price. By its very nature, conceptualizing a demand curve requires that the purchaser be a perfect competitor—that is, that the purchaser has no influence over the market price.

This is true because each point on the demand curve is the answer to the question "If this buyer is faced with this potential price, how much of the product will it purchase? Like with supply curves, economists distinguish between the demand curve of an individual and the market demand curve.

The market demand curve is obtained by summing the quantities demanded by all consumers at each potential price. The determinants of demand are: Prices of related goods and services.

Number of potential consumers. Equilibrium[ edit ] Generally speaking, an equilibrium is defined to be the price-quantity pair where the quantity demanded is equal to the quantity supplied.After studying this chapter you will be able to Describe a competitive market and think about a price as an opportunity cost Increase in Both Demand and Supply An increase in demand and an increase in supply increase the equilibrium quantity.

The change in equilibrium price is uncertain because the. This is the official website for the second edition of “Matching Supply with Demand: An Introduction to Operations Management” (McGraw Hill, ) by Gérard Cachon and Christian Terwiesch, the Wharton School, University of Pennsylvania.
