• Positive statements are judged by evidence; normative statements aren't

Economic Models: Circular Flow Diagrams

• Shows the flow of goods, services, and money between households and firms
• Households own factors of production (labor, land, capital)
• Firms use these factors to produce goods and services, and sell them back to the households
• Money flows in the opposite direction

Our Second Model: Production Possibilities Frontier

• Shows the maximum combinations of two goods an economy can produce, given its resources
• Points along the frontier represent efficient use of resources
• Points inside the frontier represent inefficiency
• Points outside the frontier are unattainable

Measuring a Nation's Income

• Gross Domestic Product (GDP) is the market value of all final goods and services produced in a country in a specific time period

Calculating GDP: Real vs. Nominal

The Components of GDP

• GDP is the sum of consumption (C), investment (I), government purchases (G), and net exports (NX)
• Consumption: household spending
• Investment: spending on capital equipment, inventories, and structures
• Government purchases: government spending
• Net exports: exports minus imports

Measuring GDP

• GDP can be measured by the sum of expenditure, factor incomes, or value added

• Factor income approach adds up factor payments to resources
• Value added approach sums the value added at each stage of production

Other Measures of Income

• Though higher GDP might suggest better lives, numerous factors like quality of life, informal sector, and environmental quality are not included in GDP calculations
