Q

Why is deflation bad?

A

People will refuse to loan out or spend money since its value is increasing as long as they hold it. This shifts aggregate demand left, which creates more deflation, etc.

Q

What is the Taylor Rule formula?

A

Federal Funds Rate Target = 1 + (1.5 x inflation rate) + (0.5 x output gap)

84
Q

How is an inflation target different than the Taylor Rule?

A

Taylor rule uses existing inflation rate. Inflation targeting tries to predict and adjust the inflation rate in advance.

85
Q

What is the political business cycle?

A

Politicians are incentivized to pump up the economy before an election to get re-elected regardless of the business cycle.

86
Q

Why is disinflation hard on an economy?

A

It usually requires AD to shift left, generating a recession.

87
Q

Why does expansionary monetary policy stop working in a liquidity trap?

A

At 0% interest nobody will loan any money anymore because it makes you no interest. This means you can’t increase spending (and therefore AD) by increasing loans once you hit 0% interest.

Q

What are two major problems with governments carrying a large debt relative to their GDP?

A

Crowding out and bankruptcy

92
Q

An increase in inflation has what impact on the Short Run Phillips Curve?

A

Movement along the curve up and to the left.

93
Q

An increase in expected inflation has what impact on the Short Run Phillips Curve?

A

Shifts the curve up/right.

94
Q

The Laffer curve serves what purpose?

A

It suggests an optimal tax rate considering the trade-off between revenues now and growth in the long run.

95
Q

Rational expectations theory suggests what?

A

That individuals can use all of the information available, including probabilities about what will happen in the future, to optimize their decisions. For instance, they can predict an increase in the inflation rate and this will impact their decisions about holding money now.

96
Q

The long run Phillips curve should have what shape and be placed at what point?

A

Vertical line at the natural rate of unemployment

97
Q

What is the rule of 70?

A

Something doubles in time = 70 / growth rate

98
Q

What is labor productivity?

A

The efficiency with which workers can produce goods for a given level of labor.

99
Q

What is total factor productivity?

A

The overall efficiency with which goods can be produced in an economy.

100
Q

What are the three main contributors to labor productivity?

A

Physical capital, human capital, and technology.

101
Q

What is the purpose of the aggregate production function?

A

To state the relative impact of physical capital, human capital, and technology on productivity.

102
Q

What is an example equation proposed for the aggregate production function?

A

GDP/worker = T * (physical capital/worker)^0.4 * (human capital/worker)^0.6

103
Q

Which productivity factor drives most GDP growth in advanced western nations like the United States?

A

Technology

104
Q

What is physical capital?

A

Physical items that aid workers in producing goods, like tools or assembly lines or computers.

105
Q

What is human capital?

A

A worker’s quality/amount of training and education.

106
Q

What is technology as a factor of production?

A

A new idea for training/education or a new invention for physical capital that is more effective at production than what came before. Computers and the internet are big, but so are sticky notes and standardized shipping containers.

107
Q

Why can’t nations just produce a huge amount of physical capital to boost productivity indefinitely?

A

Physical capital has diminishing returns. A man with two tractors is no better than a man with one tractor, and a $20,000 computer isn’t ten times more productive than a $2,000 computer.

108
Q

What is growth accounting?

A

The study of which productivity factors increase growth most effectively.

109
Q

What is the convergence hypothesis?

A

The theory that nations with low GDP/capita can take the advances from leading nations to grow their GDP/capita more rapidly and catch up to the leading nations.

110
Q

Is the convergence hypothesis true?

A

Somewhat. It seems to be working for East Asia, but not as much for South/Central America, Central Asia, or Africa.

111
Q

Name 3 ways governments can directly contribute to real GDP growth per capita.

A
  • Investing in public infrastructure (physical capital)
  • Investing in public education & job training (human capital)
  • Investing in public Research & Development (technology, e.g. NASA or public universities’ science departments)
112
Q

Name 1 way a government can indirectly contribute to real GDP growth per capita (hint: encourages the 3 productivity factors).

A

Creating a stable society so people will risk long-term investments and savings.

113
Q

What are the two main types of goods produced in a society?

A

Consumer goods and investment goods

114
Q

How is long-term economic growth represented in the production possibilities curve model?

A

The curve shifts rightward.

115
Q

How is long-term economic growth represented in the Aggregate Demand - Aggregate Supply Model?

A

LRAS shifts rightward.

116
Q

What are the Balance of Payments Accounts?

A

A way to track international payments.

117
Q

What are the two main categories of the Balance of Payments Accounts?

A

Current Account and Financial Account (sometimes also called the Capital Account)

118
Q

What are the three sub-categories of the Current Account in the Balance of Payments Accounts?

A

Imports/Exports of goods & services, factor income, and transfers

119
Q

What is “factor income” in the context of the Balance of Payments Current Account?

A

Income earned from other nations renting your factors of production. For instance, a foreigner renting your apartment or your factory.

120
Q

What is a transfer in the context of the Balance of Payments Current Account?

A

Somebody giving away money to someone outside your country. For instance, a migrant worker sending their wages to their family in their home country.

121
Q

What are the two sub-categories of the Financial Account in the Balance of Payments Accounts?

A

Official (government) sales and purchases of financial assets and private sales and purchases of financial assets.

122
Q

If Nation A has a high interest rate and Nation B has a low interest rate, assuming funds can flow internationally, what will happen to the interest rates of these nations over time?

A

They will both head towards a middle value between them as funds flow out of the low-interest country into the high-interest country for investment.

123
Q

If nation A has 8% interest and nation B has 2% interest, what interest rate will their respective loanable funds markets head towards assuming international capital flows exist?

A

5%

124
Q

How does the supply of loanable funds market graph change to represent the flow of loanable funds from one nation to another?

A

The supply curve shifts left (for nations whose money is going elsewhere) or right (for nations who have foreign money coming in).

125
Q

What is the “invisible hand of the market”?

A

Adam Smith proposed that when everyone acts in their own self-interest it seems to create more wealth overall, as if people’s behavior was guided by some “invisible hand”.

126
Q

What famous book did economist Adam Smith write in 1776?

A

Wealth of Nations

127
Q

Economics is the study of what topic?

A

How people allocate scarce resources.

128
Q

What is a scarce resource?

A

A resource like labor that is not infinite.

129
Q

What is an abundant resource?

A

A resource like water that is effectively infinite.

130
Q

What is a normative economic statement?

A

A statement about how things ought to be or personal preferences. e.g. “Welfare programs are good/bad.”

131
Q

What is a positive economic statement?

A

A statement about how things are right now factually. e.g. “Welfare programs reduce the incentive to work.” Not about whether you like them or not, just what they do.

132
Q

A command economy is…

A

An economy where the government has significant or complete control over the means of production. Think Soviet Union.

133
Q

A market economy is…

A

An economy where private citizens own the means of production. Think America in the 1800s.

134
Q

A traditional economy is…
