Chapter 5SectionMain Menu Price As price increases… Supply Quantity supplied increases Price As price falls… Supply Quantity supplied falls The Law of Supply According to the law of supply, suppliers will offer more of a good at a higher price and less of a good at a lower price.

Chapter 5SectionMain Menu How Does the Law of Supply Work? Economists use the term quantity supplied to describe how much of a good is offered for sale at a specific price. The promise of increased revenues when prices are high encourages firms to produce more. –If iPods increase to $500 each and people keep buying them the same as before, Apple will want to make more iPods to sell so Apple can make more $$ Rising prices draw new firms into a market and add to the quantity supplied of a good. –Other companies will want to sell MP3 players to take some of Apple’s customers

Chapter 5SectionMain Menu Market Supply Curve Price (in dollars) Output (slices per day) Supply Supply Curves A market supply curve is a graph of the quantity supplied of a good by all suppliers at different prices. Higher price = higher supply (or output)

Chapter 5SectionMain Menu Elasticity of supply is a measure of the way quantity supplied reacts to a change in price. Elasticity of Supply If supply is not very responsive to changes in price, it is considered inelastic. –If orange prices rise…the orange tree farmer can’t immediately produce (supply) more oranges An elastic supply is very sensitive to changes in price. –If prices of pizza went up, the local pizzeria could produce (supply) more pizza immediately

Chapter 5SectionMain Menu Costs of Production Objective: How do firms decide how much labor to hire? What are production costs? How do firms decide how much to produce? *Be sure to leave a couple blank lines under each question and answer the questions at the end of the lesson.

Chapter 5SectionMain Menu CA Standard(s) Covered 12.2 Students analyze the elements of America’s market economy in a global setting. 8. Explain the role of profit as the incentive to entrepreneurs in a market economy.

Chapter 5SectionMain Menu Marginal Product of Labor Labor (number of workers) Output (beanbags per hour) Marginal product of labor 00— –1 A Firm’s Labor Decisions Business owners have to consider how the number of workers they hire will affect their total production. The marginal product of labor is the change in output from hiring one additional unit of labor, or worker. –Lots of workers doesn’t exactly mean more stuff being made

Chapter 5SectionMain Menu Increasing, Diminishing, and Negative Marginal Returns Labor (number of workers) Marginal Product of labor (beanbags per hour) –1 –2 –3 Diminishing marginal returns occur when marginal production levels decrease with new investment (in other words, when additional workers increase total output but at a decreasing rate) Diminishing marginal returns Negative marginal returns occur when the marginal product of labor becomes negative. 89 Negative marginal returns Marginal Returns 123 Increasing marginal returns Increasing marginal returns occur when marginal production levels increase with new investment.

Chapter 5SectionMain Menu Production Costs A fixed cost is a cost that does not change, regardless of how much of a good is produced. –Examples: rent and salaries Variable costs are costs that rise or fall depending on how much is produced. –Examples: costs of raw materials, some labor costs. The total cost equals fixed costs plus variable costs. The marginal cost is the cost of producing one more unit of a good. Firms set total output to maximize profit by determining the largest gap between total revenue and total cost.

Chapter 5SectionMain Menu Production Costs Total revenue Profit (total revenue – total cost) Marginal revenue (market price) Marginal cost Total cost (fixed cost + variable cost) Variable cost Fixed cost Beanbags (per hour) $ –36 – $ $24 24 — $ $ $ $ Setting Output (chart on p. 111 in text) Marginal revenue is the additional income from selling one more unit of a good. It is usually equal to price. To determine the best level of output, firms determine the output level at which marginal revenue is equal to marginal cost.

(a) some workers increase output but others have the opposite effect (b) additional workers increase total output but at a decreasing rate (c) only a few workers will have to wait their turn to be productive (d) additional workers will be more productive 2. How does a firm set its total output to maximize profit? (a) set production so that total revenue plus costs is greatest (b) set production at the point where marginal revenue is smallest (c) determine the largest gap between total revenue and total cost (d) determine where marginal revenue and profit are the same

Chapter 5SectionMain Menu Changes in Supply Objective: How do input costs affect supply? How can the government affect the supply of a good? What other factors can influence supply? *Be sure to leave a couple blank lines under each question and answer the questions at the end of the lesson.

Chapter 5SectionMain Menu CA Standard(s) Covered 12.2 Students analyze the elements of America’s market economy in a global setting. 1.Understand the relationship of the concept of incentives to the law of supply and the relationship of the concept of incentives and substitutes to the law of demand. 7. Analyze how domestic and international competition in a market economy affects goods and services produced and the quality, quantity, and price of those products.

Chapter 5SectionMain Menu Input Costs and Supply Any change in the cost of an input such as the raw materials, machinery, or labor used to produce a good, will affect supply. –Example: Increased price of oranges means orange juice becomes more expensive to produce. As input costs increase, the firm’s marginal costs also increase, decreasing profitability and supply and goods becomes more expensive to produce. Input costs can also decrease, thus, increasing supply.

Chapter 5SectionMain Menu Government Influences on Supply By raising or lowering the cost of producing goods, the government can encourage or discourage an entrepreneur or industry. Subsidies A subsidy is a government payment that supports a business or market. Subsidies cause the supply of a good to increase. French Farmers, Asian Car makers “Story of Broke”“Story of Broke” Taxes The government can reduce the supply of some goods by placing an excise tax on them. An excise tax is a tax on the production or sale of a good. -Cigarettes, alcohol & gasCigarettes Regulation Regulation occurs when the government steps into a market to affect the price, quantity, or quality of a good. Regulation usually raises costs. -smog checks, Chinese ToysChinese Toys

Chapter 5SectionMain Menu Other Factors Influencing Supply The Global Economy –The supply of imported goods and services has an impact on the supply of the same goods and services here. –Government import restrictions will cause a decrease in the supply of restricted goods. Future Expectations of Prices –Expectations of higher prices will reduce supply now and increase supply later. Expectations of lower prices will have the opposite effect. Number of Suppliers –If more firms enter a market, the market supply of the good will rise. If firms leave the market, supply will decrease.

(a) A rise in the cost of raw materials lowers the overall cost of production. (b) The good becomes cheaper to produce. (c) The good becomes more expensive to produce. (d) This does not have any affect on the eventual price of a good. 2. When government actions cause the supply of a good to increase, what happens to the supply curve for that good? (a) It shifts to the left. (b) It shifts to the right. (c) It reverses direction. (d) The supply curve is unaffected.
