Q
Cross-price elasticity is positive:
A
Goods are substitutes
As one good’s price goes up, the other good’s quantity demanded goes down
2
Q
Cross-price elasticities is negative:
A
Good are compliments
As one good’s price goes up, the other good’s quantity demanded goes down
3
Q
A decrease in the price of a good that a consumer purchases, leaving consumer with unspent income:
A
Income effect
4
Q
Positive substitution effect & Positive income effect
A
Normal goods
the substitution and the income effects reinforce one another to cause the demand curve to be negatively sloped
When price decreases, consumption increases, leading to increases levels of unspent income
5
Q
When the positive substitution effect < negative income effect , consumption:
A
Consumption will decrese
Giffen good
When prices decrease, consumption is not pushed towards the good
6
Q
The positive substitution effect < negative income effect, causing a positively sloped demand curve, where a drop in prices decreases consumption
A
Giffen good
7
Q
A normal profit is best described as:
A
Zero economic profit;
Normal profit is the level of accounting profit such that implicit opportunity costs are just covered; thus, it is equal to a level of accounting profit such that economic profit is zero
8
Q

A company will stay in the market in the short term if:
A
Total revenue (price) >= total costs
the company is exceeding it’s variable costs

9
Q

20
Q

(i.e. reducing overtime hours)
21
Q
- unemployment rate
- average duration of unemployment
- inventory/sales ratios
- prime rate
- services inflation
- consumer installment debt

24
Q
When the central bank wants to employ open market operations, what does this mean?
A
Expansionary: the fed is buying government securities, to increase reserves/money supply, and decrease rates
Contractionary: the fed is selling government securities, to decrease reserves/money supply, and increase rates
When the fed is buying securities, that puts money into the banking system (and out of the central bank)
When the fed is selling securities, that takes money away from the banking system (and into the central bank)
25
Increases in transfer payments & decreases in tax revenues that result from an economic contraction without new legislation:
Automatic stabilizers
| dampen economic cycles
## Footnote
Taxes and transfer payments increases during a recession, thus increasing the deficit

Fiscal policy
27
Determined by the equilibrium between the demand for money and the supply of money is the ?
interest rate
28
Increased budget deficits will increase the real interest rate and thereby reduce private investment
Crowd-out effect (Macroeconomic issues that can hinder usefulness of fiscal policy)
Increased budget deficits will increase the demand for loanable funds and lead to higher interest rates, and thus lower private investment.
Crowding-out implies that an increase in government spending will choke off private investment and reduce the intended impact of fiscal policy changes on aggregate demand
29
Crowding-out implies that an ______ in government spending will choke off private investment and reduce the intended impact of fiscal policy changes on aggregate demand
increase
30

independence
33

G = T
taxation matches the level of government spending
34
Real GDP will _____, when the balance budget multiplier condition is met.
Increase
Government spending will increase G in the GDP equation
Taxation will decrease C+I in the GDP equation, but by a lesser amount
GDP= (C+I) + G + (X-M)
35
Decreasing spending or increasing taxes are:
contractionary fiscal policy actions
36
Expansionary fiscal policy tends to expand the _____ sector. Contractionary monetary policy tends to contract the ____ sector.
Public (government); expansionary fiscal policy increases government spending
Private: contractionary monetary policy causes higher interest rates, and thus less business investments
37
The central bank should increase target interest rates when the economy is:
growing at an unsustainable (above-full-employment) level
to try and slow down spending
38
To determine whether monetary policy is expansionary or contractionary, an analyst should compare the central bank's policy rate to the:

43
Unemployment rate=
unemployed / labor force
44
Labor force=
Employed + Unemployed
45
An increase in the policy rate will impact banks by:
Immediate increase in commerical bank's base rates;
Reduced credit availability
## Footnote
An increase in the policy rate (federal funds rate) will likely raise the potential penalty that banks will have to pay if they run short of liquidity and thereby reduces their willingness to lend.
46
Neutral interest rate=
real trend growth rate + inflation rate (expected or target)
## Footnote

50

52
Actual real GDP > potential real GDP
Inflationary phase
Real GDP > full employment
## Footnote
Full employment: Actual real GDP = potential real GDP
Recessionary phase: real GDP
53
Long-run aggregate supply equals:
Potential GDP/Full employment
54
The long-run aggregate supply curve is:
Perfectly inelastic; because in the long run wages and other input prices adjust to changes in the overall price level
55
The short-run aggregate supply curve:
Slopes upward; because in the short run some input prices do not adjust fully to changes in the price level
(i.e., is not perfectly inelastic)
## Footnote
Because firms can increase profit in the short run by increasing output in response to higher prices, there is a positive short-run relationship between the price level and quantity supplied.
56

95
The tendency for currency depreciation to increase a country's trade deficit in the short run is known as the:
J-curve effect
## Footnote
Currency depreciation should decrease a country's trade deficit: imports fall because domestic can purchase less and exports increase because foreigners can purchase more
But at first, the J-curve occurs because import purchases were already committed to
96

Above the kink=
Below the kink=
Above the kink, prices are more elastic where a small increase in price will cause a greater decrease in quantity demand
Below the kink, prices are less elastic where a small increase in price will cause a lesser decrease in quantity demanded
## Footnote
Price increases: more elastic
Price decrease: less elastic
121
Oligopoly competitors will lower prices to match a price reduction, but will not match a price:
Increase
122
Often in a duopoly market, producers agree to share the market to maximize total industry profits, by restricting output and putting upward pressure on prices
Collusion
123
A situation where no firm can increase it's profits by changing it's price/ouput:
Nash equilibrium
| Often an opportunity for collusive agreements
124
A government entity that regulates an authorized monopoly will most likely base regulated prices on:

Both the Laspeyres index and the Paasche index ignore the substitution effect whereby people may substitute higher priced goods or services with cheaper ones
138
Type of inflation that depends upon the relationship between **actual and potential GDP** and **industrial capacity utilization**
Demand-pull
## Footnote
The **higher the rate of capacity utilization** or the **closer actual GDP is to potential,** the more likely an economy will suffer shortages, bottlenecks, and a general inability to satisfy demand, and hence, price increases.
139

156
# Elasticities approach:
Currency depreciation will result in greater improvement in the trade deficit when either:
* Considers trade flows
* Ignores capital flows
import or export demand becomes more elastic
157
# Absorption approach:
Currency depreciation will improve the balance of trade if it increases domestic savings;
* Considers trade flows
* Considers capital flows
increases national income relative to expenditures
