Standards for Graphing a Lorenz Curve and Calculating the Gini Coefficient

Standard: 3

Name: Allocation

Individuals and organizations routinely use different decision-making systems to determine what should be produced, how it should be produced, and who will consume it. Most high school students already understand the major advantages and disadvantages of selling concert tickets using a first-come/firstserved system, rather than a lottery to select from among those who applied for tickets. Unfortunately, many students have experienced the use of force to allocate resources on the school playground. Students also know that families typically use authoritarian systems to decide how resources are used ? Mom and Dad decide. The American economy uses a market system to make many allocation decisions, and it is important for students to understand why the market system is used so extensively. Students also should be able to compare the characteristics of a market system with alternatives used more extensively in some other countries. With this understanding, students can assess the benefits and costs of alternative allocation systems when discussing difficult questions such as how incomes should be divided among people or who should receive a kidney transplant and who should not.

• 4-12: Students will understand that: Different methods can be used to allocate goods and services. People acting individually or collectively must choose which methods to use to allocate different kinds of goods and services.
• 4-12: Students will be able to use this knowledge to: Evaluate different methods of allocating goods and services, by comparing the benefits to the costs of each method.

Name: Income

In a market economy, wages and salaries the prices of labor services are determined just as other prices are, by the interaction of buyers and sellers. The buyers of labor services are employers. They are willing to pay higher wages and salaries to those employees who can produce more or better goods or services in a given amount of time. Students who understand this will appreciate the value of the skills they can acquire by completing high school, and perhaps college or a vocational training program. Understanding the forces affecting wages and other sources of income will be increasingly important in the future, when workers may change employers and careers more often than in the past. Regardless of the occupations or industries in which today's students eventually work, they are likely to find that they will have to continue their education and training to maintain or increase their earnings.

• 4-12: Students will understand that: Income for most people is determined by the market value of the productive resources they sell. What workers earn primarily depends on the market value of what they produce.
• 4-12: Students will be able to use this knowledge to: Predict future earnings based on their current plans for education, training, and career options.
