Many kids come out of college, they have a credit card and a diploma. They don't know how to buy a house or a car or health insurance or life insurance. They do not know basic microeconomics.
Microeconomics is about money you don't have, and macroeconomics is about money the government is out of.
One of the most important skills of the economist, therefore, is that of simplification of the model. Two important methods of simplification have been developed by economists. One is the method of partial equilibrium analysis (or microeconomics), generally associated with the name of Alfred Marshall and the other is the method of aggregation (or macro-economics), associated with the name of John Maynard Keynes.
Governments do not necessarily act in the national interest, especially when making detailed microeconomic interventions. Instead, they are influenced by interest group pressures. The kinds of interventions that new trade theory suggests can raise national income will typically raise the welfare of small, fortunate groups by large amounts, while imposing costs on larger, more diffuse groups.
It should be possible to emphasize to students that the level of employment is a macroeconomic issue, depending in the short run on aggregate demand and depending in the long run on the natural rate of unemployment, with microeconomic policies like tariffs having little net effect. Trade policy should be debated in terms of its impact on efficiency, not in terms of phoney numbers about jobs created or lost.
Even philosophies who have denounced pseudosciences like psychoanalysis, have condoned pseudoscientific economic theories like neoclassical microeconomics. It is far safer and easier to criticize Freud and Jung than to criticize Milton Friedman and Friedrich Hayek, because the latter are backed by political movements whereas the former are not.
Microeconomics: The study of who has the money and how I can get my hands on it.Macroeconomics: The study of which government agency has the gun, and how we can get our hands on it.
The great lesson in microeconomics is to discriminate between when technology is going to help you and when it's going to kill you. And most people do not get this straight in their heads. But a fellow like Buffett does. For example, when we were in the textile business, which is a terrible commodity business, we were making low-end textiles-which are a real commodity product. And one day, the people came to Warren and said, "They've invented a new loom that we think will do twice as much work as our old ones."
Our microeconomic indicators are stable and it gives me reason to believe that we will calmly and steadily pass this uneasy period in our economy, which has already no doubt adapted to the current situation.
