Q
Inflation is defined as what?
A
An increasing aggregate price level.
16
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.

In the short run decreasing the money supply causes aggregate output to:
Decrease
38
In the long run decreasing the money supply causes aggregate output to:

2
80
Holding everything else constant, a government's budget balance tends to do what during expansionary fiscal policy?
Decrease
81
A government typically funds spending more than it receives in tax revenues by doing what?
Borrowing money
82
If a country's aggregate output increases and all else is held constant, what will happen to the interest rate?
Increase
83
What is the Taylor Rule formula?
Federal Funds Rate Target = 1 + (1.5 x inflation rate) + (0.5 x output gap)
84
How is an inflation target different than the Taylor Rule?
Taylor rule uses existing inflation rate. Inflation targeting tries to predict and adjust the inflation rate in advance.
85
What is the political business cycle?
Politicians are incentivized to pump up the economy before an election to get re-elected regardless of the business cycle.
86
Why is disinflation hard on an economy?
It usually requires AD to shift left, generating a recession.
87
Why does expansionary monetary policy stop working in a liquidity trap?
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.

Decrease
90

Movement along the curve up and to the left.
93
An increase in expected inflation has what impact on the Short Run Phillips Curve?
Shifts the curve up/right.
94
The Laffer curve serves what purpose?
It suggests an optimal tax rate considering the trade-off between revenues now and growth in the long run.
95
Rational expectations theory suggests what?
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
The long run Phillips curve should have what shape and be placed at what point?
Vertical line at the natural rate of unemployment
97
What is the rule of 70?

99
What is total factor productivity?
The overall efficiency with which goods can be produced in an economy.
100
What are the three main contributors to labor productivity?
Physical capital, human capital, and technology.
101
What is the purpose of the aggregate production function?
To state the relative impact of physical capital, human capital, and technology on productivity.
102
What is an example equation proposed for the aggregate production function?
GDP/worker = T * (physical capital/worker)^0.4 * (human capital/worker)^0.6
103

Technology
104
What is physical capital?
Physical items that aid workers in producing goods, like tools or assembly lines or computers.

What is technology as a factor of production?
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
Why can't nations just produce a huge amount of physical capital to boost productivity indefinitely?
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
What is growth accounting?
The study of which productivity factors increase growth most effectively.
109
What is the convergence hypothesis?
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

Somewhat. It seems to be working for East Asia, but not as much for South/Central America, Central Asia, or Africa.
111
Name 3 ways governments can directly contribute to real GDP growth per capita.

Official (government) sales and purchases of financial assets and private sales and purchases of financial assets.
122
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?
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.
