Standard: 2

Name: Decision Making

• 4-12: Students will understand that: Effective decision making requires comparing the additional costs of alternatives with the additional benefits. Many choices involve doing a little more or a little less of something: few choices "are all or nothing" decisions.
• 4-12: Students will be able to use this knowledge to: Make effective decisions as consumers, producers, savers, investors, and citizens.

Standard: 7

Name: Markets and Prices

In market economies there is no central planning agency that decides how many different kinds of sandwiches are provided for lunch every day at restaurants and stores, how many loaves of bread are baked, how many toys are produced before the holidays, or what the prices will be for the sandwiches, bread, and toys. Students should understand that, instead, most prices in market economies are established by the interaction between buyers and sellers.Understanding how market prices and output levels are determined helps people anticipate market opportunities and make better choices as consumers and producers. It will also help them realize that market allocations are impersonal.

• 4-12: Students will understand that: Markets exist when buyers and sellers interact. This interaction determines market prices and thereby allocates scarce goods and services.
• 4-12: Students will be able to use this knowledge to: Identify markets in which they have participated as a buyer and seller and describe how the interaction of all buyers and sellers influences prices. Also, predict how prices change when there is either a shortage or surplus of the product available.

Standard: 16

Name: Role of Government and Market Failure

Why does government pay private construction firms to build roads and highways? Why do the firms that build the roads not own them themselves and charge tolls to users? All kinds of goods and services are produced and distributed through private markets, so why not roads and highways, too? In flipping through the pages of the telephone directory, we observe a vast array of businesses and government agencies. Why do markets work well to supply much of what we want, while failing to produce other things we want? Citizens should understand the limitations and shortcomings of markets and how some government policies attempt to compensate for market failures. Learning the economic as well as the political and social reasons for public sector services helps citizens make better choices about the appropriate size and scope of markets and government. It is also important that students be able to evaluate redistributive effects of government programs.

• 4-12: Students will understand that: There is an economic role for government in a market economy whenever the benefits of a government policy outweigh its costs. Governments often provide for national defense, address environmental concerns, define and protect property rights, and attempt to make markets more competitive. Most government policies also have direct or indirect effects on people's incomes.
• 4-12: Students will be able to use this knowledge to: Identify and evaluate the benefits and costs of alternative public policies, and assess who enjoys the benefits and who bears the costs.

Standard: 8

Name: Role of Prices

Understanding the role of prices as signals and incentives helps people anticipate market opportunities and make better choices as producers and consumers. It also helps citizens understand the consequences and weigh the costs and benefits of price controls, such as minimum-wage laws and rent ceilings, that set legal minimum or maximum prices and result in sustained surpluses or shortages.

• 4-12: Students will understand that: Prices send signals and provide incentives to buyers and sellers. When supply or demand changes, market prices adjust, affecting incentives.
• 4-12: Students will be able to use this knowledge to: Predict how changes in factors such as consumers' tastes or producers' technology affect prices.
