MACROECONOMIC MARKETS: Three sets of markets that make up the macroeconomy--product, financial, and resource--which exchange the three primary types of macroeconomic commodities--gross production, legal claims, and factor services. The four macroeconomic sectors--household, business, government, and foreign--interact through these three sets of markets. The primary objective of macroeconomic theories is to explain activity that takes place in these three sets of markets.

An hypothesis is a possible, even probable, scientific relationship. An hypotheses is a candidate to become a principle. Hypothesis must be tested before becoming principles.- A possible hypothesis: The distance between a passing car and a jogger depends on the driver's political philosophy.
- Alternative hypotheses can also explain differences in distance between jogger and passing car.
An hypothesis that seems reasonable is not necessarily right. It must be verified with real world data.- The scientific method does not accept an explanation at face value. It needs to prove an explanation is correct.
- Scientists check to see if a reasonable explanation is consistent with the data. The scientific process is all about verifying hypotheses.
- To test our hypothesis, ask people about passing distance and political affiliation.
- While subjective data, based on asking people, can be useful, objective methods of data collection are usually preferred. Let's use lasers.
- Government is a fruitful source of objective data.

KEYNESIAN ECONOMICS A theory of macroeconomics developed by John Maynard Keynes based on the proposition that aggregate demand is the primary source of business-cycle instability and the most important cause of recessions. Keynesian economics points to discretionary government policies, especially fiscal policy, as the primary means of stabilizing business cycles and tends to be favored by those on the liberal end of the political spectrum. The basic principles of Keynesian economics were developed by Keynes in his book, The General Theory of Employment, Interest and Money, published in 1936. This work launched the modern study of macroeconomics and served as a guide for both macroeconomic theory and macroeconomic policies for four decades. Although it fell out of favor in the 1980s, Keynesian principles remain important to modern macroeconomic theories, especially aggregate market (AS-AD) analysis.
