Overview of Macroeconomics

• Macroeconomics focuses on the “Circular Flow of Income, Resources and Products” as a whole, not individual entities (firms, consumers, etc.)

• Macroeconomics focuses on broad aggregates such as GDP, unemployment and inflation. Penson et al. 2009

• “Macroeconomists study aggregated indicators such as GDP, unemployment rates, and price indices to understand how the whole economy functions.” http://en.wikipedia.org/wiki/Macroeconomics

Macroeconomic Indicators

• Many, many macroeconomic indicators (measures) exist – 1,000’s!

• Socioeconomic Indicators: – Population ( http://www.census.gov/– Income (www.census.gov)

• Economic Indicators: – unemployment rates

National Income and Product Accounts

• A national accounting system (much like a business would use) started in the 1930’s (post-Depression) to measure and monitor the value of economic activity in the U. S. economy.

• Viewed the economy much like a business.– Focused on income, expenditures and products

produced. – Continually modified and improved.

National Income Acounts

• Most important measure - • Gross Domestic Product (GDP) – a single dollar

value of the total of all goods and services produced in the United States whether by domestic or foreign resources.

• A measure of growth in the economy and a basis for other measures.

Ways to measure GDP

• There are 2 ways to measure GDP – provides a system of “check and balances”

– Expenditure Method – looks at product markets - the sum of all sales of goods and services in the economy.

• GDP = Consumption + Investment + Gov’t Expenditures + (Exports – Imports)

Very famous equation!

United States’ GDP

– Income Method – looks at resource markets - the sum of all expenditures on resources in the economy.

• GDP = Employee compensation + Corporate profits + Proprietor's Income + Rental income + Net Interest

– Both way produce the same number!

Nominal vs. Real GDP

• National Accounts are measures in dollars, but the dollar “value” (the things that can be purchased with a dollar) changes – called, inflation or deflation.

• Thus, “nominal values” must be adjusted (usually, deflated) to determine “constant” or “real” values.

• “Constant” is outdated; government now used “Chained” – Concept is the same, adjust for inflation; methodology is different.– http://en.wikipedia.org/wiki/Chained_dollars

• Bottom line, it is important to distinguish between real and nominal values when making comparisons over time.

Examples of Inflation

Keep in mind that the Minimum Wage was $1.15!

As a point of reference, real GDP fell by 8.5%, 6.5% and 12.9% annually over the 1930–1932 period.

Issues with GDP

• Problems - depend on the purpose:• GDP includes:

• pollution control – pollute a river, clean it up and increase GDP!

• clean up from natural disaster - • war expenditures – go to war and increase GDP!

Issues with GDP

• GDP excludes:• leisure activities – a nice walk or bike ride! • volunteerism • income distribution considerations• private transactions (bartering)

Summary

• Macroeconomic is concerned with the performance of our overall economy.

• Our economy is measured and monitored via a series of socioeconomic and economic indicators.

• Where are we going? – Macro> Stock Market> Food and Fiber System





We can measure macro economic activity in either resource markets or product markets. Result is the same…



National income = GDP
