CFA Level 1 - All Topics and Questions Flashcards
Current Ratio Formula is? + is a higher current ratio better or worse
Current Ratio = Current assets / current liabilities. The higher the current ratio the more likely it is that the company will be able to pay its bills.
Quick Ratio formula is? and is a higher quick ratio better or worse?
Cash + marketable securities + receivables / current liabilities. The higher the quick ratio the more likely the company can pay its bills
For a lessor how are lease payments treated on the cash flow statement?
Investing income, operating cash inflow, or principal is treated as operating cash and interest is treated as investment income.
The entire lease payment is an operating cash inflow.
Accelerated depreciation, shorter useful lives and lower salvage values are examples of which accounting strategy?
Conservative, this type of accounting results in lower income in the current period and higher income in future years. We describe choices that result in higher income in the current period as aggressive accounting.
other things equal, increasing days sales payable will have what impact on operating cash flow?
Stretching accounts payable will increase operating cash flow. Accounts payable are bills it must pay to suppliers. These bills are recorded on the companies balance sheet as current liabilities
what are mutually exclusive and exhaustive events?
Mutually exclusive events are events that cannot happen at the same time. For example, you can’t run backwards and forwards at the same time.
Exhaustive events are events where at least one of them must occur. For example, heads and tails are mutually exclusive and collectively exhaustive. Exhaustive is all possible outcomes.
probability: conditional versus unconditional
Unconditional probability is the likelihood that an event will occur regardless of whether other events have taken place or any other conditions are present. It is also known as marginal probability.
Conditional probability is the likelihood of an event occurring based on the occurrence of a previous event. It is calculated by multiplying the probability of the preceding event by the updated probability of the succeeding event.
What is a probability distribution
a probability distribution describes the probability of all possible outcomes and must equal 1.
What is a discrete random variable and a continuous random variable?
A discrete random variable is one for which the numbers of all possible outcomes can be counted and measured and has a positive probability. i.e. flipping a coin only has two outcomes.
A continuous random variable is one which the numbers of possible outcomes is infinite. usually something that can be measured but has infinite options like height.
What is a diminishing marginal productivity/returns?
the production function says that two workers should be able to produce 2x of that of 1 worker. This would carry on as you add labor however, adding additional workers can result in less than 100% productivity.
Managers use it to make decisions in the short-run, such as how much variable input to combine with fixed inputs to maximize profit.
total revenue is greatest in the part of the demand curve which is:
A) Elastic
B) inelastic
c) unit elastic
C. unit elastic
Unit elastic, or unitary elastic, is an economic concept that describes a situation where a change in one variable causes an equally proportional change in another variable. In other words, if the price of an item changes by a small margin, the quantity of the item will also change by a small margin.
Demand can be classified as elastic, inelastic or unitary. An elastic demand is one in which the change in quantity demanded due to a change in price is large. An inelastic demand is one in which the change in quantity demanded due to a change in price is small.
when the price of a good decreases and the consumption also decreases it is most likely that the:
A) income effect is negative, substitution effect is positive
B) Income and substitution effects are both negative
c) income and substitution effects are positive
A: the substitution effect of a price decrease is always positive but the income effect can be both. Consumption of a good will decrease when the price of the good decreases only if the income effect is negative and greater than the substitution effect.
The income effect predicts that people will demand more when their income grows, and vice versa
A good is classified as inferior if:
A) income elasticity is is negative
B) own price elasticity is negative
C) Cross point elasticity is negative
an inferior good is one in which it has a negative income elasticity of demand.
In economics, an inferior good is a good or service that people tend to buy more of when they have lower incomes and less of when their incomes rise.
describe the 5 characteristics for determining a market structure as perfect competition, monopolistic, oligopoly, or pure monopoly?
number of firms relative to their size, degree to which firms differentiate their product, bargaining power of the firms with respect to pricing, barriers to entry into or exiting the industry, degree to which firms compete on factors other than price.
Describe the perfect competition as it relates to the 5 main characteristics?
many firms, lower barriers to entry, good substitutes, competes on price only. no pricing power (market sets the price).
Describe monopolistic as it relates to the 5 main characteristics?
many firms, low barriers to entry, good substitutes (but differentiated), competes on price and marketing, some purchasing power.
Describe a monopoly as it relates to the 5 main characteristics?
single firm, very high barriers to entry, no substitutes that are good, competes on advertising, significant pricing power.
What is marginal costs versus marginal revenue?
marginal cost is the cost of producing one more unit of a product or service. Marginal revenue is the additional revenue from selling one more unit.
When should a firm stop expanding priduction
when marginal cost equals marginal revenue
what is economic profit
The total revenues, less the opportunity cost, which includes a cost of normal return to production.
What is GDP and what does it include.
a nations gdp is the total of all its consumer and government spending, investments, and exports minus imports. It does not include the resale of goods and services and it also does not include transfers such as social security and welfare.
what is a gdp deflator
a price index that can be sued to turn te nominal gd into real gdp
Do gains and losses as well as expenses appear on the income statement
Yes both
shares in a publicly traded company that owns gold mines and mining operations are considered what: a financial asset, physical asset, real asset
a financial asset because its still shares that simply have a claim against real assets.
A stock has a beta of 1.55 and a expected return of 17.3%. If the risk free rate is 8% the expected market risk premium is?
The term automatic stabilizer’s refers to?
increases in transfer payments (spending) and decreases in tax revenue that results from an economic contraction without new legislation.
covariance vs correlation
covariance measures the direction of a relationship between two variables, while correlation measures the strength of that relationship.
A positive covariance means that the two variables are positively related and move in the same direction. A negative covariance means that when one variable is high, the other tends to be low.
in the dominant firm model of oligopoly, it is least likely that one firm:
A) Effectively sets the prices in the market
B) is the innovation leader in the product development
c) Has a significant cost advantage over its competitors
B “is the innovation leader in the product development”.
the dominant firm model of oligopoly is based on the assumption that one firm has a significant cost advantage which allows it to set the price in the market and control a relatively large share of the industry production and sales. it does not assume that one firm will be the innovation leader. In fact being more innovative is one of the factors that allows smaller firms to survive.
what is a convenience yield?
The benefit of holding the physical product rather than contract or detractive.
= spot price - futures price
Merger Arbitrage
its an event driven hedge fund strategy. Usually the fund buys the shares of the company being acquired and shorts the company being acquired.

Early, mezzanine, angel investment
Early stage
Angel investing is more commonly known for investments at the idea stage.
Seed capital refers to funding for market research and product development.
Early stage investing is usually for commercializing
Late stage is for growing/expanding
mezzanine is to prepare for an IPO
An equity hedge fund strategy that focuses primarily on exploiting overvalued securities is called what?
a) a fundamental value strategy
b) event driven strategy
c) short bias strategy
a short bias strategy
an event driven strategy focuses on companies involved in mergers, or financial distress as an example.
A fundamental value strategy focuses on stocks that are undervalued.
using derivatives to hedge the changes in value of inventory is considered:
fair value hedge
hedge accounting is a method of accounting in which entries to adjust for fair value of a security and its hedge are treated as one.
the lower limit of a normal distribution is:
negative one, zero, negative infiinity
in a normal distribution the lower limit is technically negative infinity
the curve extends indefinity in a negative direction, this means theoretically the distribution includes values close to negative infinity but have extremely low probabilities of occurring.
An enterprise value model for equity valuation is most accurately described as:
asset based model, discounted cash flow model, multiplier model
multiplier model, its analyzed as a multiple of revenue or earnings and compared to other firms.

A) a decrease in the quantity of imports
B) a shift in production to higher cost suppliers
C) increased revenue for the government
C

CFA institute will enforce the following punishments except:
public censure, a fine, suspension, revocation of the use of the trademark
a fine. the CFA institute does not issue fines.
what is a probability distribution
a probability distribution describes the probability of all possible outcomes and must equal 1.
probability - unconditional versus conditional
unconditional probability is not concerned with past or future events and conditional probability is when one event affects the probability of another
mutually exclusive event versus exhaustive events
mutually exclusive events cannot happen at the same time i.e. rolling a 1 and a 6 on a dice at the same time.
Exhaustive events have all possible outcomes.

what is this describing “pre tax financial income based on financial accounting standards” “also known as income before tax or earnings before tax”.
Accounting profit
“net amount of an asset or liability used for tax reporting purposes”
tax base
What happens to the balance sheet, income statement and cash flow statement when a company issues a bond at par?
on a balance sheet assets and liabilities go down by the proceeds from the bond sale. On the income statement interest expense increases by the amount of the coupon rate. On the cash flow stmt issuance proceeds are a cash inflow from financing, coupon payments are a cash outflow from operating activity and at maturity face value repayment is a cash outflow from financing activity.
what are debt covenants and are they specifically negative or positive? why are they important?
debt covenants are restrictions imposed by the lender on the borrower to protect the lenders interests. debt covenants protect both the lender and the borrower by defining the terms and reducing default risk.
Affirmative covenants; the borrower promises to do certain things i.e. make timely payments.
negative covenants; the borrower promises to refrain from certain activities that may affect the ability to repay the debt.

finance lease
if the benefits of ownership and the risk of ownership is not transferred to the lessee then its called an operating lease.
this type of annuity pays at the end of a compounding period?
Ordinary annuity
an annuity due pays at the beginning of the compounding period.
when you sell more items than you have bought recently you will end up selling older items and therefor selling items that have a lower carrying value and your profit will go up. This is what type of liquidation?
LIFO Liquidation

What is a GDP deflator
cash + marketable securities + receivables / current liabilities
quick ratio
FYI the higher the quick ration the more likely the company will be able to pay its short term bills.

central bank
IPO vs direct listing
While many companies choose to do an initial public offering (IPO), in which new shares are created, underwritten, and sold to the public, some companies choose a direct listing, in which no new shares are created and only existing, outstanding shares are sold with no underwriters involved.
outside investors who buy out all of the companies shares and remove its public listing are participating in what type of buyout
leveraged
a group of managers by the company shares

an analyst assigns a rating of 1,2,3,4 or 5 to all companies in a stock exchange. Value 1 is highly likely to increase the dividend and 5 is unlikely to increase its dividend. these values are LEAST likely described as:
nominal data, ordinal data, discrete data
nominal data
nominal data is also known as categorical or qualitative data. categories or labels that cannot be ordered numerically.
discrete data is commonly in the form of numbers this data is countable and has a finite number of values.
ordinal data is statistical data and has a natural order where distance between the values is known.
This data type is commonly in the form of numbers this data is countable and has a finite number of values.

core inflation removes the cost of what?
food and energy.
headline inflation refers to the total cost of an index for all goods.
an income statement where each line item is expressed as a percentage of a base figure.
Common size income statement
A common-size cash flow statement is least likely to provide payments to employees as a percentage of:
A) revenues for the period.
B) operating cash flow for the period.
C) total cash outflows for the period.
B
There are two formats for a common-size cash flow statement, expressing each type of outflow as a percentage of total cash outflows or as a percentage of total revenue for the period. Operating cash flow for the period mixes inflows and outflows and is not used to calculate percentage flows for payment made.
is a measure of the amount of cash generated by a company’s normal business operations.
operating cash flow
forms of non operating cash flow would be dividends and interest from other investments.
Greg Allen is a security analyst and visits David Dawson, the Chief Financial Officer of Edmonds Company. Dawson reveals a great deal of nonmaterial financial data to Allen, data that Dawson routinely reveals to all security analysts who visit him. From this data and other industry information, Allen conjectures that Edmonds is likely to make a tender offer for another company in the industry, a fact that if true would be considered material to the value of the company. Allen:
A) can publish his conclusion in a research report.
B) must not disseminate the information or use it for trading purposes until the tender offer is announced.
C) should send a copy of the report to Dawson for verification before disseminating the report to clients.
A) can publish his conclusion in a research report.
While the information that Allen received from the Edmonds CEO may be non-public, we are also told that it is non-material. Because Allen has reached his investment conclusion through an analysis of public information together with items of non-material non-public information (i.e., “mosaic theory”), publishing this conclusion is not a violation of the Code and Standards.
This theory allows analysts to combine nonmaterial, nonpublic information with public information. Analysts can act on this collection of information without risking violation.
Mosaic theory
net income - preferred dividends / weighted average of common shares outstanding
basic EPS
The Widget Company had net income of $1 million for the period. There were 1 million shares of widget common stock outstanding for the entire period. If there are 100,000 options outstanding with an exercise price of $40, what is the diluted earnings per share for Widget common stock if the average price per share over the period was $50?
A) $0.98.
B) $1.00.
C) $0.99.
Use the Treasury stock method
Proceeds = 100,000 ($40) = $4,000,000
Shares assumed purchased with proceeds= $4,000,000/$50 = 80,000 shares
Potential dilution = 100,000 – 80,000 = 20,000 shares
Basic EPS = $1/share
Diluted EPS = $1,000,000 / 1,020,000 = $0.98/share
The inventory-to-sales ratio for manufacturing and trade is classified as a:
A) lagging indicator.
B) coincident indicator.
C) leading indicator.
A
The inventory-to-sales ratio for manufacturing and trade is considered a lagging indicator because it peaks after the economy does, even though it is sometimes used in forecasting economic activity.
The what hypothesis always includes the “equal to” condition.
Null Hypothesis
A null hypothesis is a statistical hypothesis that states that there is no statistical significance in a set of observations. It is also known as the default hypothesis. The null hypothesis is represented by H0.
The null hypothesis is one of two mutually exclusive hypotheses about a population in a hypothesis test.
The other hypothesis is called the alternative hypothesis. Researchers use a statistical test to weigh evidence for and against the null and alternative hypotheses.
Ed Verdi has a long position in a European put option on a stock. At expiration, the stock price is greater than the exercise price. The value of the put option to Verdi on its expiration date is:
A) negative.
B) zero.
C) positive.
B “Zero”
At expiration, the value to the holder (long position) of a put option on a stock is the greater of zero or the exercise price minus the stock price. If the stock price is greater than the exercise price, the value of a put option to the holder is zero and the holder will allow the option to expire unexercised.
these theorists believe that the Fed’s tools are powerful and should not be used to moderate fluctuations in prices and outputs. Thus, steady, predictable growth is the best monetary policy. They believe in the power of the money supply, not fiscal policy, to affect prices and outputs.
Monetarist
this describes what type of investing strategy: “a firm invests the majority of a portfolio passively and uses active strategies for the remaining portion’
a core-satellite approach.
this describes what type of investing strategy: “refers to specifying the percentages of a portfolio’s value to allocate to specific asset classes.”
Strategic Asset Allocation
This describes what type of investing strategy: “refers to allocating a portfolio’s overall permitted risk among strategic asset allocation, tactical asset allocation, and security selection.”
Risk budgeting
Which of the following is least important as a reason for a written investment policy statement (IPS)?
A. The IPS may be required by regulation.
B. Having a written IPS is part of best practice for a portfolio manager.
C. Having a written IPS ensures the client’s risk and return objectives can be achieved.
C.
C is correct. Depending on circumstances, a written IPS or its equivalent may be required by law or regulation and a written IPS is certainly consistent with best practices. The mere fact that a written IPS is prepared for a client, however, does not ensure that risk and return objectives will in fact be achieved.
Two years from now, a client will receive the first of three annual payments of $20,000 from a small business project. If she can earn 9 percent annually on her investments and plans to retire in six years, how much will the three business project payments be worth at the time of her retirement?
In summary, your client will have $77,894.21 in six years if she receives three yearly payments of $20,000 starting in Year 2 and can earn 9 percent annually on her investments.
Question
Providing information about the performance and financial position of companies so that users can make economic decisions best describes the role of:
auditing.
financial reporting.
financial statement analysis.
This is the role of financial reporting. The role of financial statement analysis is to evaluate the financial reports.
A company’s profitability for a period would best be evaluated using the:
A. balance sheet.
B. income statement.
C. statement of cash flows.
Solution
B is correct. Profitability is the performance aspect measured by the income statement. The balance sheet portrays the financial position. The statement of cash flows presents a different aspect of performance.
values that describe a quality or characteristic of a group of observations and therefore can be used as labels to divide a dataset into groups to summarize and visualize.
Categorical data (or qualitative data)
The two types of categorical data are nominal data and ordinal data.
In a frequency distribution, the absolute frequency measure:
A. represents the percentages of each unique value of the variable.
B. represents the actual number of observations counted for each unique value of the variable.
C. allows for comparisons between datasets with different numbers of total observations.
B is correct. In a frequency distribution, the absolute frequency, or simply the raw frequency, is the actual number of observations counted for each unique value of the variable. A is incorrect because the relative frequency, which is calculated as the absolute frequency of each unique value of the variable divided by the total number of observations, presents the absolute frequencies in terms of percentages. C is incorrect because the relative (not absolute) frequency provides a normalized measure of the distribution of the data, allowing comparisons between datasets with different numbers of total observations.
This type of frequency is calculated as the absolute frequency of each unique value of the variable divided by the total number of observations
Relative frueqency
Year 1 2.48 Year 7 −9.19
Year 2 −2.59 Year 8 −5.11
Year 3 9.47 Year 9 1.33
Year 4 −0.55 Year 10 6.84
Year 5 −1.69 Year 11 3.04
Year 6 −0.89 Year 12 4.72
What is the relative frequency and the cumulative relative frequency for the bin −1.71% ≤ x < 2.03%.
Relative frequency is .333 and cumulative relative frequency is .583.
The cumulative relative frequency of a bin identifies the fraction of observations that are less than the upper limit of the given bin. It is determined by summing the relative frequencies from the lowest bin up to and including the given bin. The following exhibit shows the relative frequencies for all the bins of the data from the previous exhibit:
The term “…………” means that the events cover all possible outcomes.
Exhaustive
If the probability that Zolaf Company sales exceed last year’s sales is 0.167, the odds for exceeding sales are closest to:
1 to 5.
1 to 6.
5 to 1.
1 to 5
In this case, the probability that Zolaf Company’s sales exceed last year’s sales is 0.167, and the probability of it not exceeding last year’s sales is 1 - 0.167 = 0.833.
Now, let’s calculate the odds:
Odds = 0.167 / 0.833 ≈ 0.2
(Number of successful outcomes) / (Total number of outcomes)
Probability forumla
After six months, the growth portfolio that Rayan Khan manages has outperformed its benchmark. Khan states that his odds of beating the benchmark for the year are 3 to 1. If these odds are correct, what is the probability that Khan’s portfolio will beat the benchmark for the year?
50%
67%
75%
75%
To calculate the probability that Khan’s portfolio will beat the benchmark for the year based on these odds, you can use the following formula:
Probability = (Number of successful outcomes) / (Total number of outcomes)
In this case, the successful outcome is beating the benchmark, and the total number of outcomes is the sum of successful outcomes and unsuccessful outcomes, which is 3 (beating the benchmark) + 1 (not beating the benchmark) = 4.
Now, calculate the probability:
Probability = 3 (beating the benchmark) / 4 (total outcomes) = 3/4
You are using the following three criteria to screen potential acquisition targets from a list of 500 companies:
Product lines compatible
0.20
Company will increase combined sales growth rate
0.45
Balance sheet impact manageable
0.78
If the criteria are independent, how many companies will pass the screen?
P(ABC) = P(A)P(B)P(C) = (0.20)(0.45)(0.78) = 0.0702. As a consequence, (0.0702)(500) = 35.10, so 35 companies pass the screen.
The probability of an event given that another event has occurred is a:
Conditional Probability
Which of the following best describes how an analyst would estimate the expected value of a firm using the scenarios of bankruptcy and non-bankruptcy? The analyst would use:
A. the addition rule.
B. conditional expected values.
C. the total probability rule for expected value.
C is correct. The total probability rule for expected value is used to estimate an expected value based on mutually exclusive and exhaustive scenarios.
Which of the following is a continuous random variable?
The value of a futures contract quoted in increments of $0.05
The total number of heads recorded in 1 million tosses of a coin
The rate of return on a diversified portfolio of stocks over a three-month period
C is correct. The rate of return is a random variable because the future outcomes are uncertain, and it is continuous because it can take on an unlimited number of outcomes.
If the price elasticity coefficient of the demand curve for paper clips is equal to –1, demand is:
A. elastic.
B. inelastic.
C. unit elastic.
C is correct. When the price elasticity of demand coefficient is –1, demand is said to be unit elastic, or unitary elastic.
Unit elastic demand is when the price elasticity of demand is equal to -1. This means that the percentage change
in quantity demanded is equal to the percentage change in price.
This indicates that the quantity demanded is responsive to changes in price. If price increases, quantity demanded decreases, and if price decreases, quantity demanded increases.
Positive PED (in absolute terms, greater than 1)
This means that the percentage change in quantity demanded is exactly equal to the percentage change in price. Demand is considered to be proportionate to price changes.
Unitary PED (in absolute terms, equal to -1):
The demand for membership at a local health club is determined by the following equation:
Qdhm=400−5Phm
where Qdhm
is the number of health club members and Phm is the price of membership. If the price of health club membership is $35, the price elasticity of demand is closest to:
–0.778.
–0.500.
–0.438.
A is correct. Inserting the price of $35 into the demand function, quantity demanded is calculated as
Qdhm=400−5(35)=225
At a price of $35 per health club membership, the elasticity of demand is
Price elasticity of demand = (ΔQdhm/ΔPhm)×(Phm/Qdhm)
Price elasticity of demand = –5 × (35/225) = –0.778
Question
A market structure characterized by many sellers with each having some pricing power and product differentiation is best described as:
oligopoly.
perfect competition.
monopolistic competition.
C is correct. Monopolistic competition is characterized by many sellers, differentiated products, and some pricing power.
the ratio of the percent change in quantity demanded to the percent change in price.
Price elasticity of demand

Which of the following types of data would most likely be organized as a two-dimensional array?
Panel Data
Panel data combine time series data with cross-sectional data and are typically organized as data tables, which are two-dimensional arrays.
The intervals in a frequency distribution should always be:
non-overlapping
Intervals within a frequency distribution should always be non-overlapping and closed-ended so that each data value can be placed into only one interval. Interval widths should be defined so that data are adequately summarized without losing valuable characteristics.
Difference between absolute frequency and relative frequency?
An absolute frequency is a number of occurrences.
Relative frequency is shown as a %.
The vertical axis of a histogram shows:
In a histogram, the intervals are on the horizontal axis and the frequency is on the vertical axis.
Types of Probability
Empirical vs Subjective vs A Priori
Empirical is based on experience and real data analysis, Subjective is based on perception (what you think is going to happen), A Priori is based on reasoning (what should happen given math and logic).
Unconditional probability vs conditional probability
Unconditional probability (Marginal) is the probability of something happening regardless of outside or other events. Conditional probability is the likely hood of A occurring given that event B has already occurred.
An interest rate is best interpreted as:
a required rate of return or the opportunity cost of consumption.
An interest rate from which the inflation premium has been subtracted is known as:
a real interest rate.
Real interest rates are those that have been adjusted for inflation. (Module 1.1, LOS 1.b)

6.96%
Which of the following is most accurate regarding a distribution of returns that has a mean greater than its median?
A) It is positively skewed.
B) It is a symmetric distribution.
C) It has positive excess kurtosis.
A distribution with a mean greater than its median is positively skewed, or skewed to the right. The skew pulls the mean. Kurtosis deals with the overall shape of a distribution, not its skewness. (Module 2.5, LOS 2.l)

Two Undconditional Events?
1 x conditional and 1 x undconditional?
By the multiplication rule of probability, the joint probability of two events, P(AB), is the product of a conditional probability, P(A | B), and an unconditional probability, P(B).
Two mutually exclusive events:
Cannot or can both occur?
cannot both occur.
What is Kurtosis?
Kurtosisis a measure of the degree to which a distribution is more or lesspeakedthan a normal distribution.
Leptokurtic vs platykurtic vs mesokurtic
Answer
MAD - Mean Absolute Devation
The average of the absolute values values of the deviations of the indivual observations from the arithmatic mean. 1) calculate the mean 20 minus the value from the mean 3) divide that by the number of observations
Type of mean for calculating compounding growth rates or investment returns over multiple periods.
Geometric Mean
Quartile =
Quintile =
Decile =
Percentile =
Quartile. The distribution is divided into quarters.
Quintile. The distribution is divided into fifths.
Decile. The distribution is divided into tenths.
Percentile. The distribution is divided into hundredths (percents).
Price elasticity of demand. More or less elastic means?
More elastic means the higher the price the less demand, in-elastic means the price usually doesnt change the demand as much.
Measure of elasticity?
> 1 & <1
> 1 = demand is elastic
<1 = demand is inelastic
The sensitivity of quantity demanded to a change in income is termed:
Income Elasticity
For most goods, the sign of income elasticity is positive—an increase in income leads to an increase in quantity demanded. Goods for which this is the case are termed:
For other goods, it may be the case that an increase in income leads to a decrease in quantity demanded. Goods for which this is true are termed:
Normal Goods
Inferior Goods
PED - % increase in price leads to a larger % decrease in in demand is a elastic or inelastic demand?
Elastic demand
PED - Percent increase in price leads to a smaller % decrease in demand is a elastic or inelastic demand?
Inelastic demand
If the quantity of goods sold never changes, regardless of price this is an example of a perfectly ……..
Perfectly inelastic demand
3 factors that influence PED?
Available substitutes, proportion of income spent on the product, time elapsed since the change in price. The more substitutes available the more elastic the demand, the more you spend on a good the more elastic the demand, longer that goes by since the change in price the more elastic the product could become.
Calculating elastcity basic formula
% change in quantity / % change in Price
PED - Price Elasticity of Demand Formula =
current price / current quantity x slope coeeficient of demand
Qdgas = 138,500 - 12,500 Pgas - Calculate the price elasticity of demand at a gasoline price of $3 per gallon
1) 138,500 - 12,500 (3) = Quantity or 101,000 2) current price / current quantity x slope Coeff or 3 / 101,000 x - 12,500 = -0.37 3) therefore we can say that at a price of $3, demand is inelastic because its less than 1.
Substitute & Income effect
Substitute effect come into play when the price of good X is decreased it always results in more demand. Its substituted positively. The income effect can be good (normal) or bad (inferior). Increasing income could have you substitute ground beef for steak, making ground beef inferioir and steak a normal good.
Giffen Good vs Veblen Good
AGiffen goodis an inferior good for which the negative income effect outweighs the positive substitution effect when price falls. A Veblen good is one for which a higher price makes the good more desirable. The idea is that the consumer gets utility from being seen to consume a good that has high status (e.g., Gucci bag
production function
The quantity of output that a firm can produce can be thought of as a function of the amounts of capital and labor employed. Such a function is called aproduction function.
Marginal Product =
Additonal Output
Dimishing Marginal Returns
When the marginal product (additional output) is increasing at a decresing rate. 1 worker produces 10 outputs, worker 2 produces 7 outputs & worker 3 produces 4 outputs.
Cost curves - AVC & ATC (what should you do if your selling price is between the AVC and the ATC?
(Average Variable Cost) & ATC (Average Total Cost) average meaning per unit. If your price is below the AVC you should shut down, If you are selling at a price between the AVC and ATC you should keep going in the short term but shut down in the long-term, you must be selling above the ATC to be making profits.
Marginal Cost
Cost of producing an additonal unit
SRATC
Short Run Average Total Cost
Perfect Competition definition
Perfect competitionrefers to a market in which many firms produce identical products, barriers to entry into the market are very low, and firms compete for sales only on the basis of price. Firms face perfectly elastic (horizontal) demand curves at the price determined in the market because no firm is large enough to affect the market price.
Monopolistic Competition compared to perfect competition and an oligopoly.
In perfect competition a company has many competitors and low barrier to entry. Only difference between products is price and marketing. In perfect competition the differntion is price. In an oligopoly there are just less firms competing.
Perfect Competition Characteristics
- homogeneous product 2. Large number of indipendent competitors 3. perfectly elastic demand 4. No barriers to entry or exit 5. Supply and demand determine market place
A profit maximizing firm will produce the quantity,Q*, when MC =
A profit maximizing firm will produce the quantity,Q*, when MC = MR
Price discrimination
Price discriminationis the practice of charging different consumers different prices for the same product or service. Examples are different prices for airline tickets based on whether a Saturday-night stay is involved (separates business travelers and leisure travelers) and different prices for movie tickets based on age.
DWL - Dead weight Loss
Difference between the price and what consumers are willing to pay. Price discrimination helps to lower DWL.
Marginal Revenue
the revenue gained by producing one additional unit of a good or service.
Perfect Competition =
Price = MR = MC
Perfect competition is characterized by:
Perfect competition is characterized by:
Many firms, each small relative to the market.
Very low barriers to entry into or exit from the industry.
Homogeneous products that are perfect substitutes, no advertising or branding.
No pricing power.
Monopolistic competition is characterized by:
Monopolistic competition is characterized by:
Many firms.
Low barriers to entry into or exit from the industry.
Differentiated products, heavy advertising and marketing expenditure.
Some pricing power.
Oligopoly markets are characterized by:
Oligopoly markets are characterized by:
Few sellers.
High barriers to entry into or exit from the industry.
Products that may be homogeneous or differentiated by branding and advertising.
Firms that may have significant pricing power.
Monopoly is characterized by:
Monopoly is characterized by:
A single firm that comprises the whole market.
Very high barriers to entry into or exit from the industry.
Advertising used to compete with substitute products.
Significant pricing power.
If a firm’s long-run average total cost increases by 6% when output is increased by 6%, the firm is experiencing:
diseconomies of scale. Increasing long-run average total cost as a result of increasing output demonstrates diseconomies of scale.
Total revenue is greatest in the part of a demand curve that is:
unit elastic. Total revenue is maximized at the quantity at which own-price elasticity equals –1. (Module 8.1, LOS 8.a)
Income elasticity formula
Income elasticity = I0/ Q0× ∆Q / ∆
A demand function for air conditioners is given by:
QDair conditioner = 10,000 – 2 Pair conditioner + 0.0004 income + 30 Pelectric fan – 4 Pelectricity
At current average prices, an air conditioner costs 5,000 yen, a fan costs 200 yen, and electricity costs 1,000 yen. Average income is 4,000,000 yen. The income elasticity of demand for air conditioners is closest to:
Substituting current values for the independent variables other than income, the demand function becomes:
QDair conditioner = 10,000 – 2(5,000) + 0.0004 income + 30(200) – 4(1,000)
= 0.0004 income + 2,000.
The slope of income is 0.0004, and for an income of 4,000,000 yen, QD = 3,600.
Income elasticity = I0 / Q0 × ∆Q / ∆I = 4,000,000 / 3,600 × 0.0004 = 0.444.
(Module 8.1, LOS 8.a)
When the price of a good decreases, and an individual’s consumption of that good also decreases, it ismost likelythat: A)
the income effect and substitution effect are both negative.
B)
the substitution effect is negative and the income effect is positive.
C)
the income effect is negative and the substitution effect is positive.
C - The substitution effect of a price decrease is always positive, but the income effect can be either positive or negative. Consumption of a good will decrease when the price of that good decreases only if the income effect is both negative and greater than the substitution effect. (Module 8.2, LOS 8.b)
When a firm operates under conditions of pure competition, marginal revenue always equals:
Price - When a firm operates under conditions of pure competition, MR always equals price. This is because, in pure competition, demand is perfectly elastic (a horizontal line), so MR is constant and equal to price. (Module 9.1, LOS 9.a)
Cournot model.
Answer
Dominant firm model.
Answer
Kinked demand model.
Answer
Nash equilibrium Model
Answer
Which of the following statementsmost accuratelydescribes a significant difference between a monopoly firm and a perfectly competitive firm? A perfectly competitive firm: A)
minimizes costs; a monopolistic firm maximizes profit.
B)
maximizes profit; a monopolistic firm maximizes price.
C)
takes price as given; a monopolistic firm must search for the best price.
C - Monopolists must search for the profit maximizing price (and output) because they do not have perfect information regarding demand. Firms under perfect competition take the market price as given and only determine the profit maximizing quantity. (Module 9.4, LOS 9.b)
Keynesian vs monetarist theorist
Keynesian economists believe that fiscal policy, through its effect on aggregate demand, can have a strong effect on economic growth when the economy is operating at less than full employment. Monetarists believe that the effect of fiscal stimulus is only temporary and that monetary policy should be used to increase or decrease inflationary pressures over time. Monetarists do not believe that monetary policy should be used in an attempt to influence aggregate demand to counter cyclical movements in the economy.
A country’s debt ratio is?
A country’sdebt ratiois the ratio of aggregate debt to GDP
Fiscal policy toolsinclude spending tools and revenue tools. What are the spending and revenue tools?
Spending tools = Transfer payments (entitlement programs), Current spending (on goods and services), capital spending (infrastructure). Revenue Tools = Direct taxes (levied on income or wealth), Indirect taxes (are levied on goods and services).
Fiscal Multiplier
Changes in government spending have magnified effects on aggregate demand because those whose incomes increase from increased government spending will in turn increase their spending, which increases the incomes and spending of others.The magnitude of the multiplier effect depends on the tax rate and on the marginal propensity to consume.
Disposable Income
is income after taxes
Fiscal Multiplier
fiscal multiplier = 1 / 1−(MPC)(1−t)
Discretionary Fiscal Policy
Fiscal policy is implemented through changes in taxes and spending. This is calleddiscretionary fiscal policy. Discretionary fiscal policy would be designed to be expansionary when the economy is operating below full employment. Fiscal policy aims to stabilize aggregate demand. During recessions, actions can be taken to increase government spending or decrease taxes. Either change tends to strengthen the economy by increasing aggregate demand, putting more money in the hands of corporations and consumers to invest and spend.
Three factors influence money demand:
- Transaction demand, for buying goods and services.
- Precautionary demand, to meet unforeseen future needs.
- Speculative demand, to take advantage of investment opportunities.
Money supply is determined by central banks with the goal of managing inflation and other economic objectives.
Tarriff?
