What is Economics?
• Studies inflation, unemployment, business cycle, economic growth, income inequality • Studies how a consumer’s decisions, a firm’s decisions, and a laborer’s decisions, etc. • Economics is the studies of how economy functions — macroeconomics versus microeconomics • Microeconomics provides foundation for us to understand macroeconomics • Note the tentative nature of economic knowledge

What is Economics?
• On Oct 4, 2008, Alan Greenspan explained to the Congress what had gone wrong with the financial markets over the past year. • “In other words,” a house representative said, “you found that your view of the world, your ideology, was not right. It was not working.” • “Precisely,” replied Greenspan. ‘That’s precisely the reason I was shocked, because I had been going for forty years or more with very considerable evidence that it was working exceptionally well.” • Bottom line: we should treat our economic knowledge as tentative; should be wary of its limitation

The Assumption of Economic Man
• In everyday life, the individual cares more about himself/herself than about others. • Adam Smith (17231790) in his Wealth of Nations (1776) used “self-love” to describe this propensity.
