Econ Flashcards
Cross-price elasticity is positive:
Goods are substitutes
As one good’s price goes up, the other good’s quantity demanded goes down
Cross-price elasticities is negative:
Good are compliments
As one good’s price goes up, the other good’s quantity demanded goes down
A decrease in the price of a good that a consumer purchases, leaving consumer with unspent income:
Income effect
Positive substitution effect & Positive income effect
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
When the positive substitution effect < negative income effect , consumption:
Consumption will decrese
Giffen good
When prices decrease, consumption is not pushed towards the good
The positive substitution effect < negative income effect, causing a positively sloped demand curve, where a drop in prices decreases consumption
Giffen good
A normal profit is best described as:
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
A company will stay in the market in the long term if:
A company will stay in the market in the short term if:
Total revenue (price) >= total costs
the company is exceeding it’s variable costs
Revenue > variable costs
Profit is maximized when:
marginal revenue = marginal cost
Total revenue - total cost = is maximized
Output increases in the same proportion as input increases occur at:
constant returns to scale
Positive substitution effect > negative income effect:
Inferior good
Occurs when a business charges the maximuim possible price a consumer is willing to pay:
First-degree price discrimination (perfect price discrimination)
Second degree: invovles using the quantity purchased as the basis for the pricing of a particular good
Oligopoly firms are said to be:
Interdependent
Economic profits is different from accounting because it includes:
Opportunity costs
Economic profit= accounting profit - opportunity costs
All firms will increase output when:
MR > MC
MR= Market price (perfect competition) & will stop production when Price = MR = MC
For all firms, profits are maximized where:
MR = MC
(Maximizes profits, not revenue)
Unemployment rate=
unemployed / labor force
Labor force=
Employed + Unemployed
Competitive market that produces less output, and the sum of consumer and producer surplus is reduced:
Monopoly
A firm’s initial response to an emerging economic contraction is:
Reduce output, by using less capital and labor
(i.e. reducing overtime hours)
- unemployment rate
- average duration of unemployment
- inventory/sales ratios
- prime rate
- services inflation
- consumer installment debt
lagging indicator
Economic growth:
-Increasing average duration of unemployment indicates a downturn has occured and growth is expected, if decreases it means the economic upturn has occured and firms have started hiring again
-increase in consumer installment debt follows increases in average aggregate income
-in economic recovery, new job seekers enter the labor force and increase the unemployment rate
Economic decline:
-Increasing inventory, relative to sales, appear after a peak and show signs of slowing economic growth
- Real personal income
- Industrial output
Coincident Indicators
Economic growth:
-increased industrial output
Economic Decline:
-decline in real personal income shows a slowdown in business activity
- Building permits !
- Stock price
- initial unemployment claims
- manufacturing new orders
- spread of short & long term interest rates !
leading indicators
Economic growth:
-Builders are seeking permits in anticipation of an economic expansion
Economic decline:
-Narrowing spread forecasts an economic decline
When the central bank wants to employ open market operations, what does this mean?
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)
Increases in transfer payments & decreases in tax revenues that result from an economic contraction without new legislation:
Automatic stabilizers
dampen economic cycles
Taxes and transfer payments increases during a recession, thus increasing the deficit
Refers to actions by a government to influence economic activity through changes in taxes and government spending
Fiscal policy
Determined by the equilibrium between the demand for money and the supply of money is the ?
interest rate
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
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
Economic actors come to believe the inflation rate will be near the central bank’s target and factor this inflation rate into their decisions, show’s the central bank’s:
credibility
Periodic inflation reports enhance the ______ of a central bank
transparency
A central bank that determines both the policy rate and the method for computing the inflation rate is said to have ______.
independence
Balanced budget multiplier condition:
government spending = Tax revenue
G = T
taxation matches the level of government spending
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)
Decreasing spending or increasing taxes are:
contractionary fiscal policy actions
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
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
To determine whether monetary policy is expansionary or contractionary, an analyst should compare the central bank’s policy rate to the:
Neutral interest rate:
Expansionary = Neutral > Policy rate
Contractionary = Neutral < Policy rate
Banks are able to borrow from the Fed at the _____.
discount rate
The ______ is the interest rate banks charge other banks to borrow reserves from other banks
federal funds rate
The rate that commercial banks charge their best customers.
prime rate
Fisher effect states that nominal rate of interest=
Nominal rate of interest= real rate + expected inflation
Unemployment rate=
unemployed / labor force
Labor force=
Employed + Unemployed
An increase in the policy rate will impact banks by:
Immediate increase in commerical bank’s base rates;
Reduced credit availability
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.
Neutral interest rate=
real trend growth rate + inflation rate (expected or target)
Neutral > policy rate (fed funds rate) = Expansionary
Neutral <policy rate = contractionary
Represents increased productivity that cannot be directly accounted for by increases in capital & labor, driven by changes in technology
Total factor productivity
Regulatory practice of setting prices at a level where the monopoly firm’s total average cost curve intersects the demand curve:
Average cost pricing
Regulatory practice of setting prices at a level where the monopoly firm’s marginal cost curve intersects the demand curve:
Marginal cost pricing
In a perfectly competitive industry, the short-run supply curve for the market is the:
Sum of individual supply curves for all firms in the industry
- reducing the volatility of domestic asset prices
- maintaining control of exchange rates
- keeping domestic interest rates low
- protecting strategic industries from foreign ownership.
Reasons for a government to impose restrictions on capital flows into/out of its country
Actual real GDP > potential real GDP
Inflationary phase
Real GDP > full employment
Full employment: Actual real GDP = potential real GDP
Recessionary phase: real GDP <potential GDP
Long-run aggregate supply equals:
Potential GDP/Full employment
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
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)
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.
When the government is spending more and taxing less:
Expansionary Fiscal Policy
Deficit: G - T = positive
When the government is spending less and taxing more:
Contractionary fiscal policy
Surplus: G - T = negative
Aggregate Demand Equation=
AD= C + I + G (X-M)
