Macroeconomics
Field of economics that studies movement and trends in the economy as a whole.
Examines changes in unemployment, GDP, and inflation.
Microeconomics
analyzes the market behavior of individual consumers and firms in an attempt to understand their decision-making process.
Focuses on patterns of:
Law of supply
A fundamental law of microeconomics that states, all other factors being equal, as the price of a good or service increases, suppliers will increase the quantity of that good or service.
(As the price of an item goes up, suppliers will attempt to maximize their profits by increasing the quantity offered for sale).
Example: when college students learn a certain profession pays more, the supply of students studying that profession will increase.
Example: when consumers start paying more for cupcakes than donuts, bakeries will increase their cupcake output to increase profits.
Example: when your employer pays time and a half for overtime, the number of hours you are willing to supply for work increases.
Law of demand
Fundamental microeconomic principle about how price affects demand.
States that, for all other things remaining constant, the lower the price of a good or a service, the higher the demand will be. Conversely, the higher the price, the lower the demand.
Example: when shirts go on sale, you might buy 3 instead of 1. The quantity you demand increases because the price has fallen.
Example: when plane tickets become more expensive, you’re less likely to travel by air and more likely to choose a less expensive option. The amount of plane tickets you demand decreases to zero because the cost has gone up.
Durables
a.k.a. “durable goods”
A category of consumer goods, durables are products that do not have to be purchased frequently. (things you buy to last).
Consumer goods
a.k.a. “final goods”
Products that are purchased for consumption by the average consumer. They are the end result of production and manufacturing and are what the consumer will see on the shelf.
Clothing, food, cars, and jewelry are all consumer goods.
Basic materials like copper are not consumer goods because they must be transformed into usable goods.
PMI
Purchasing Managers’ Index
An indicator of the economic health of the manufacturing sector.
Based on 5 major indicators:
Malthusian
Ideas of Thomas Malthus, the 18th century British economist.
At the time, people said we would one day evolve into a utopia.
Malthus said there would always be a starving lower class, as long as population multiplied faster than the means of subsistence.
Capitalism
A system of economics based on:
Capitalism is generally characterized by…………………?
Competition between producers.
In capitalism, the production of goods and services is based on…………………?
Supply and demand in the general market (market economy) rather than through central planning (planned economy).
When did capitalism rise to prominence?
It came to prominence with the end of the feudal economies.
(It is the dominant economic system in developed countries).
What are two cornerstones of capitalism?
- wage labor
What are the two biggest criticisms of capitalism?
- the constant need for consumption to sustain economic growth.
Capital
Wealth.
Zero-sum game
A situation in which one person’s gain is equivalent to another’s loss, so the net change in wealth or benefit is zero.
Ex: we each have a penny. If you win, you get my penny and if I win I get your penny.
This is the opposite of a win-win situation - such as a trade agreement that benefits both nations, or a lose-lose situation, like war.
What are macro and microeconomics?
The two vantage points from which the economy is observed.
Macro - from a distance, seeing the economy as a whole (the larger picture)
Micro - from close-up, seeing all the small parts that make up the economy
As economists gain understanding of certain phenomena they can help nations and people make more informed decisions when allocating resources.
Market economy
Planned economy
a.k.a. “Command Economy”
(A key feature of any communist society - China, Cuba, North Korea, and the former Soviet Union all had one)
What is the opposite of a surplus?
A shortage
What are the signs that we are in a recession?
What causes recessions?
Inflation is the biggest contributor to recessions (the higher the rate of inflation, the smaller the percentage of goods and services that can be bought with the same amount of money)
Stagflation
A condition of slow economic growth and high unemployment - a time of stagnation - accompanied by inflation.
It occurs when the economy isn’t growing but prices are (which is very bad for an economy).
What are two generally accepted theories about the cause of inflation?
Demand-pull inflation
Cost-push inflation
