Business Cycle

more or less regular pattern of expansion and contraction around the trend of gross domestic product (GDP) growth

New cards
New cards

What are the 4 business cycle phases?

These are the phases of?

1. expansion phase

2. the peak

3. the contraction or recession

4. the trough

New cards
New cards

Expansion phase

where more resources become employed and actual output approaches potential output. In the extreme there may be over employment as workers work overtime and the utilization rate for plant and equipment exceeds normal levels

New cards
New cards

The peak

the highest point of output during the cycle. The economy is operating above the long-term growth trend of real GDP

New cards
New cards

The contraction or recession

more resources become unemployed and actual output falls below potential output.

New cards
New cards

The trough

the lowest point of output during the cycle. There are high unemployment rates, a decline in annual income, and overproduction. Real GDP stops declining and starts expanding

New cards
New cards

How a business cycle is measured

the period of time the peak of one cycle though the four phases to the peak of the next cycle

New cards
New cards

Economic Growth

the trend or the path of economic growth measures the level of output (potential output) that could be produced if all resources were fully employed over time.

New cards
New cards

The real business cycle model

is based on the premise that fluctuations in output and employment result from real supply shocks that periodically hit the economy, and that markets adjust rapidly to the shock and always remain in equilibrium

New cards
New cards

The political business cycle model

explains the business cycle as resulting from interactions between economy policy decisions and political decisons designed to influence voter behavior.

New cards
New cards

The insufficient aggregate expenditure model

is based on the premise that a business cycle is caused by inadequate spending

New cards
New cards

What are the key components of the aggregate expenditure model

These are the key components of what?

(c) personal consumption

(I) business investment

(G) government expenditures

(X) the net difference between exports and

(M) Imports

New cards
New cards

What is the formula for the aggregate expenditure model

GDP = C + I + G + (X-M)

New cards
New cards

The accelerator model

assumes that the business cycle is caused by the volatility of investment spending

New cards
New cards

Unemployment rate

measures the percentage of the labor force that is not working. (The number of unemployed workers divided by the number of workers in the labor force multiplied by 100)

New cards
New cards

Labor force

equals all U.S residents 16 years or older who are not institutionalized, working, unemployed, actively looking for work

New cards
New cards

Discouraged workers

unemployed workers who are not actively seeking employment, and they are not considered to be a part of the labor force.

New cards
New cards

fricitional unemployment

occurs due to normal labor turnover

New cards
New cards

Seasonal unemployment

occurs in regual and recurring patterns in some industries

New cards
New cards

cyclical unemployment

unemployment that is related to the general level of economic activity and tends to rise during the recession phase

New cards
New cards

Structual unemployment

arises when changes in technology and international competitiveness change the skills required to perform jobs and/or change the location of jobs

New cards
New cards

What are the costs of unemployment

These are the costs of?

a. unemployment represents forgone output, and causes actual output to be less than the potential output. The primary economic cost of unemployment is the loss of output. The economy is not producing its potential output.

b. There is a social dimension to unemployment as a loss of a job causes problems with self-esteem. Generally, there is also an increase in domestic violence as the unemployment rate increases in the average time workers are main unemployed increases.

c. The burden of unemployment is unequally shared. Lower skilled workers have a higher unemployment rates than higher skilled workers.

New cards
New cards

full employment

The level of employment, where the actual unemployment rate is equal to the natural rate of unemployment(NRU)

New cards
New cards

when does natural rate of unemployment occur? (NRU)

this causes the occurrence of?

Occurs when the number of jobseekers is equal to the number of job vacancies and actual unemployment would be greater than zero due to frictional unemployment

Perfect competition

A large number of sellers producing a standardize product with easy entry and exit into an out of the industry

New cards
New cards

Market equilibrium

New cards
New cards

Monopolistic competition

is characterized by having many small firms are produced differentiated products. The firm has some degree of control over product price

New cards
New cards

Oligopoly

A market structure characterized by a few firms that sell either standardized or differentiated product and we're entry into the industry is difficult

New cards
New cards

Kinked demand curve

One type of demand curve that affirm operating in an oligopoly might face. One strategic assumption is that competitors will follow a price reduction, but will not follow a price increase.

New cards
New cards

Price leader ship

Another form of competition in an oligopoly. It often result in an implicit agreement that coordinates prices without having the firms engage in illegal collusion.

New cards
New cards

Monopoly

There is a single seller of a product for which there are no close substitutes. The firm has considerable control over price and is a price maker.

New cards
New cards

Consumer surplus and producer surplus

The demand curve and supply curve show what consumers and producers are willing and able to buy or offer for sale at various alternative prices at a given moment in time. The interaction of buyers and sellers in the market place determines an equilibrium price.

New cards
New cards

Demand

The quantity of goods or services that buyers are willing and able to purchase at various alternative prices at a given moment in time. A critical point to remember is that the consumer must be both willing and able to purchase for their desires

Demand measures the responsiveness of consumer demand for a product relative to a change in income

New cards
New cards

Cross elasticity of demand

Measures responsiveness of consumer demand for a product relative to the change in the price of another product. If consumers buy less of the original product, then the goods are complements.

New cards
New cards

Complementary goods

Goods and services that are used in conjunction with each other. When the price of one good falls, and the quantity demanded of that good rises, the demand of the other good rises.

New cards
New cards

Inferior goods

Goods or services, who is demand decreases as a consumer income increases, assuming prices remain constant

New cards
New cards

Normal goods

Goods or services, who is demand, increases as consumers income increases, assuming prices remain constant

New cards
New cards

Substitute goods

Goods and services that can be used in place of each other in at least some of their uses. When the price of one good falls, the quantity demanded of that good increases, and the demand for the other good without a price decrease falls.

New cards
New cards

Law of diminishing marginal utility

A proposition that describes how an individual satisfaction derived from the consumption of each additional unit of the good or service, declines as consumption of that good or service increases

New cards
New cards

Inflation

A sustained increase in the average level of prices, and is measured by using a fixed wheat price index

New cards
New cards

New good bias

New goods constantly replace all goods, and the index does not compare about the price and quality between the old and new goods

New cards
New cards

Quality change bias

The quality of many items improves each year in the improvement must be compared to the increase in the price of the good

New cards
New cards

Commodity substitution bias

Consumers have a tendency to cut back on the consumption of relatively more expensive goods and substitute. Relatively cheap are good as price rises.

New cards
New cards

Outlet substitution bias

As price increase, there is a tendency for more people to shop at discount, stores, and in recent years, online shopping has allowed consumers to search for lower prices for many products

New cards
New cards

Demand pull inflation

Caused by an access in total spending relative to the economies, current capacity to produce goods and services

New cards
New cards

Cost push inflation

Occurs when rising prices result from an increase in resource cost and loss, arise in per unit cost of production

New cards
New cards

Hyper inflation

And extremely rapid rate of inflation, that usually has a devastating impact on real output, unemployment

New cards
New cards

Deflation

A sustained decline in the general price level

New cards
New cards

Redistribution effects

There is a difference between nominal income, and the purchasing power of that income. When inflation occurs, not everyone's nominal income rises at the same rate and, therefore, there will be some redistribution of purchasing power as inflation persists.
