Economics 19e Flashcards
founder of microeconomics
Adam Smith
founder of macroeconomics
1936, when John Maynard Keynes published his revolutionary General Theory of Employment, Interest and Money.
Keynes developed an analysis of what causes business cycles, with alternating spells of high unemployment and high inflation.

technique that applies the tools of statistics to economic problems
The following are some of the common fallacies encountered in economic reasoning:
- The post hoc fallacy. The first fallacy involves the inference of causality. The post hoc fallacy occurs when we assume that, because one event occurred before another event, the first event caused the second event. This occurred in the Great Depression of the 1930s in the United States. Some people had observed that periods of business expansion were preceded or accompanied by rising prices. From this, they concluded that the appropriate remedy for depression was to raise wages and prices. This slowed recovery
- Failure to hold other things constant.
- The fallacy of composition. Sometimes we assume that what holds true for part of a system also holds true for the whole. In economics, however, we often find that the whole is different from the sum of the parts. When you assume that what is true for the part is also true for the whole, you are committing the fallacy of composition.
The key points to understand about slopes are the following:
- The slope can be expressed as a number. It meaures the change in Y per unit change in X, or “the rise over the run.”
- If the line is straight, its slope is constant everywhere.
- The slope of the line indicates whether the relationship between X and Y is direct or inverse.

Globalization
a term that is used to denote an increase in economic integration among nations. Increasing integration is seen today in the dramatic growth in the flows of goods, services, and finance across national borders.

United States
Governments have three main economic functions in a market economy:
- Governments increase efficiency by promoting competition, curbing externalities like pollution, and providing public goods.
- Governments promote equity by using tax and expenditure programs to redistribute income toward particular groups.
- Governments foster macroeconomic stability and growth—reducing unemployment and inflation while encouraging economic growth—through fiscal and monetary policy.
Since World War II, for example, there have been X recessions in the United States, some putting millions of people out of work. These fluctuations are known as the business cycle.

Gary Becker
Daniel Bernoulli, a member of a brilliant Swiss family of mathematicians, observed in 1738
that people act as if the dollar they stand to gain in a fair bet is worth less to them than the dollar they stand to lose.This means that they are averse to risk and that successive new dollars of wealth bring them smaller and smaller increments of true utility.
Jeremy Bentham (1748–1832)
accomplished early introduction of the utility notion into the social sciences
extended Bentham’s utility concept to explain consumer behavior.
William Stanley Jevons (1835–1882). Jevons thought economic theory was a “calculus of pleasure and pain,” and he developed the theory that rational people would base their consumption decisions on the extra or marginal utility of each good.
The ideas of Jevons and his coworkers led directly to the modern theories of ordinal utility and indifference curves developed by
Vilfredo Pareto, John Hicks, R. G. D.
Equimarginal principle
The fundamental condition of maximum satisfaction or utility. It states that a consumer will achieve maximum satisfaction or utility when the marginal utility of the last dollar spent on a good is exactly the same as the marginal utility of the last dollar spent on any other good.
The seventeenth-century philosopher Francis Bacon held that
the purest of human pleasures was gardening.
developing a better understanding of the role of asymmetric information and the market for “lemons.”
George Akerlof
received the prize for “the analysis of human judgment and decision-making . . . and the empirical testing of predictions from economic theory by experimental economists.”
Daniel Kahneman and Vernon L.Smith
Ordinal variables
ones that we can rank in order, but for which there is no measure of the quantitative difference between the situations. Economists today generally reject the notion of a cardinal (or measurable) utility that people feel or experience when consuming goods and services. Utility does not ring up like numbers on a gasoline pump.
Rather, what counts for modern demand theory is the principle of ordinal utility. Under this approach, consumers need to determine only their preference ranking of bundles of commodities.
In between substitutes and complements are
independent goods, such as beef and textbooks, for which a price change for one has no effect on the demand for the other.
Merit goods
whose consumption is thought intrinsically worthwhile, and the opposite, which are demerit goods, whose consumption is deemed harmful.
