3 ModuleThe ProductionPossibilitiesCurve Model • KRUGMAN'S • MACROECONOMICS for AP* Margaret Ray and David Anderson
Do Now – yes I mean “now” Lesson 2 – Activity 2 sections: 2.1, 2.2, 2.3 and 2.5 2.4 is a challenge question for our Econ geeks.
Unit 1 Test Thursday / Friday - Sept. 11 & 12 Modules 1 & 3 20-30 AP style multiple choice questions. “Tackle the Test” questions are a good sample.
Today’s Objectives • Understand how the production possibilities frontier (PPF) shows opportunity costs for an economy. • Use PPF to show efficient and inefficient output and economic growth. • Learn to identify macro and microeconomic issues
Opportunity Cost - Efficiency efficient full employment Not feasible Inefficient, unemployment
Economic Growth • Expansion of the economy’s production possibilities • Availability of resources (land, labor, capital, entrepreneurship) • Technology: not just electronics, any process that is used to produce goods and services. Example: assembly line.
Summary • PPF shows opportunity cost of using society’s resources to produce two types of products. • Efficiency = cannot make more of something without giving up something else. • Constant vs. declining opportunity costs. • Underemployment • Economic growth: more resources or better technology.
Micro vs. Macroeconomics Macroeconomics: • Entire economy • “Economic aggregates” Microeconomics: • Individuals, households and firms
Macro or Micro? What will be the effect if the Federal Reserve lowers interest rates to stimulate the economy?
Macro or Micro? What will happen to coffee prices if there is a drought in Brazil?
