Consumption

=Units Output - Units Invested

Technology

A *proximate(direct) cause* of growth and thus a *factor of production*. This is knowledge about how the world works which is used to produce goods and services (something can be BOTH physical capital and this--but THIS is used to *advance production*).

Human Capital

A *proximate(direct) cause* of growth and thus considered a *factor of production*. This is the productive knowledge and skills that workers acquire through education, training, and experience. (A way to measure this would be to find the average education level of a population, a country with a higher average education would have more of this factor).

Physical Capital

A *proximate(direct) cause* of growth; the stock of tools, structure, and equipment. This is the main *factor of production*.

John Nash

A Nobel Laureate who advanced understanding on *non-cooperative behaviors*. This is when there is some optimal thing that could happen but because we assume/do not cooperate, it does not happen. (Ex: single girl wants BF and boys want a GF but all assume the girl already has a BF so she stays single even though it seems to be an optimal situation).

Consumption

A component of GDP in the expenditure approach. The spending by *households* on goods and services including *durable* (cars) and *non-durable* (clothes and food) goods.

GDP(Gross Domestic Product)

A measure of *well-being*(USUALLY a good indicator). Gives a summary statistic about a country's *standard of living*. Higher levels of this means: -higher life expectancy -more educated females -better health outcomes

Further

A prediction of the Solow Model: countries that are ___________ from the steady-state capital tend to grow rapidly (due to diminishing marginal returns and investment is a larger than the amount needed to keep up with depreciation--lines are further apart).

A. Real income and employment.

A recession is a period of significant, widespread declines in: A. Real income and employment. B. Real income and unemployment. C. Exports and imports. D. Inflation and unemployment.

Recession

A significant, *widespread* decline in real *income and employment*. (Ex: Not just one mcdonalds closing but alot of mcdonalds closing across the country).

Catch-Up Growth

A type of growth that shifts the production function; takes advantage of ideas, technologies, or methods if management that are *already in existence*. --Movement along the production function curve, increase in capital stock inputs

Cutting-Edge Growth

A type of growth that shifts the production function; this is the development of *new* ideas and focusing on developing *new technologies* for resources. (Better ideas make us produce more output from the same amount of capital inputs). --Looks like a jump; we get more outputs from same amount of inputs

Consumption

According to the Expenditure Approach, this is the factor that mostly drives GDP.

Exceed

Dependable Legal System

An *ultimate(indirect) cause* of growth. This is important because it ensures that property-rights are well enforced and helps the society run better.

Honest Government

An *ultimate(indirect) cause* of growth. This refers to a corruption-free government that does not deviate from its commitments. This is important because resources that are used in bribing politicians and bureaucrats (instead of being used for productive things) are *wasted resources*. --More corrupt countries have LOWER GDPs because resources are being wasted.

Property Rights

An *ultimate(indirect) cause* of growth. This refers to the right to receive benefits from, sell, or transfer a property in addition to the right to exclude others from the property. Without this, people will have incentive to *free-ride*(properties belong to the community and people can consume without paying for it --China in 1970s).

Expenditure Approach

An approach to calculating GDP that measures spending in order to tell us how productive we are (looks at money *leaving* the household). (looksby adding up aggregate spending on domestically produced final goods and services in the economy--the sum of consumer spending, investment spending, government purchases of goods and services, and exports minus imports.

Increase in GDP

An increase in the average level of *prices* and/OR additional *production* causes this. *******Remember that an increase in production IS good but an increase in price levels is NOT! Yet, they both do the same thing to GDP...

Market

An institution that can be used to allocate resources. Behavior that is based on self-interest can lead to an overall benefit to society according to *Adam Smith's "Invisible Hand" metaphor*. ---Occasionally fails to allocate (public good provisions, externality) and then we DO need government intervention.

Absolute Advantage

The ability to produce the same good using *fewer inputs* than another producer.

Comparative Advantage

The ability to produce the same good with the *lowest opportunity cost* compared to other producers.

The approach to GDP measurement that measures how much we earn (income/wages) in order to measure how many products we produce (looks at money *entering* the household). that determines GDP as the sum of all incomes received by economic agents contributing to production

Real GDP per capital

The best indicator of well-being aka the best GDP measure. This is a rough estimate of the standard of living in a nation and is corrected for *inflation* by using the same set of prices in every year.

Depreciation

The deterioration of capital, rendering these units useless.

Solow

The first to formulate the idea of growth. He ONLY considers *physical capital*.

8.5%(per year)

The growth rate of Japan from 1950 to 1970 following their status of poorest country following WWII. This makes them an example of a *growth miracle*.

A. High

The marginal product of capital in China is __________ relative to the marginal product of capital in developed economies. A. High B. Moderate C. Low D. Zero

75%(book says 73%)

The percentage of the world's population (~5.2 billion people) that lives in a country where the *GDP per capita* is LESS than that world average.

Production Function

The relationship between inputs and outputs. We assume that technology equals 1 (unless told otherwise) and only focus on *physical capital*. Ultimately the formula describes the relationship between GDP and physical capital (how much GDP is needed to produce one unit of physical capital). --This is a line that gets flatter overtime because the longer you work, the more tired you get. *NOT A 1:1 RATIO OF INPUT TO OUTPUT*

Incentives

The rewards and penalties that motivate behaviors. These include *both* monetary and non-monetary. Can influence where you live, whether you vote, producers and consumers, where you go to school, etc.

The sale of sugar will contribute to GDP when the buyer is: A. Krispy Kreme Doughnuts B. A mother who is baking cookies at home. C. A Mexican food restaurant. D. A grocery store chain.

Poverty, wealth

The world income distribution tells us that _____ is normal and ______ is unusual.

Fixed Costs

These DO NOT MATTER when facing a trade-off (opportunity cost situation). (Ex: Once you pay $5 to get into the buffet, this does NOT affect how many burgers you eat at the buffet).

Proximate(direct) Causes

These causes of growth are *factors of production*. Have a direct impact on our outcome (determinant of growth(

Ultimate(Indirect) Causes

These causes of growth are the *institutions*.

Rational

These type of individuals will make decisions based on the additional gains (marginal benefits) and additional losses (marginal costs) of an action. This allows an individual to MAXIMIZE their profit/utility/social welfare/etc.

Argentina(Nigeria is another disaster example)

This country is an example of a *growth disaster*. Their GDP per capita was 75% as large as the U.S.'s in the 1900s but is only *1/3 of the size of the U.S.'s by 2000*. The gap is continuing to grow.

Diminishing Marginal Returns

This explains why the *production function* curve has a *concave* shape. This is the idea that the *marginal*(additional) product of capital diminishes as more and more capital is added. (Ex: giving a millionaire a dollar does much less than giving a very poor person a dollar..). --Following WWII Germany and Japan both grew faster than the US because they both had NOTHING --China has a higher growth rate than the US because they have less capital than us

MB=MC

This is the optimal level of MC and MB because it means we are maximizing our net gains.

Good Institution

This type of institution creates incentives in a way that individuals in their own self-interest achieve the objectives of what society wants. Ex: Reduced Tuition- creates incentive so more people can go to school and then more people are educated and can innovate and behave well in society.

50

Today, GDP per capita is more than _______ times as large in the richest countries as in the poorest countries (*even though in the past they were somewhat similar*--$700-1000).
