Currency depreciation can occur as the home country sells more
of the home country’s currency to buy the other currency; this

Pink Salmon
Supply shifts right for pink salmon
New technology

Demand shifts left for pink salmon
Increases in consumers’ income
Reductions in the price of substitutes
LO7
Supply shifts due to new technology which increases the catch
and lowers the cost of fishing. High profits encourage new
fishers to enter the industry. Demand shifts due to increases in
consumers’ income causing them to shift away from canned fish
such as pink salmon. Reductions in the price of substitutes for
pink salmon, such as fresh salmon from the Atlantic, cause the
demand for pink salmon to fall.

When a supply curve is upsloping, any change in demand is
tempered by a change in quantity supplied. However, when the
supply curve is vertical and fixed, any change in demand only
results in changes in price; the quantity supplied stays the same
no matter what the price is. There is only so much land

secondary market.
In the market for tickets to the Olympic curling preliminaries
the demand curve, D, and supply curve, S, produce an
equilibrium price below the P1 price printed on the ticket. At
price P1 the quantity of tickets demanded is less than the

delving into the specifics of your concept, you must first
identify and overcome any concerns
that may arise in the future, even if they are years
away(Patnaik,2019).
This will help you to take a step back and look at your idea
from a more comprehensive
perspective. This post provides an outline of what should be
included in a business plan, as
well as sample business plans to help you get started on the
correct path when writing your
own plan. According to experts, any decision that a firm makes
should be accompanied by a
complete business plan that details the planned expenses as well
as any potential problems
that may arise. When it comes to business plans, even among
competitors in the same
industry or industrial area, they are rarely the same as one
another(Hider,2018).
For the most part, however, the fundamental features of all
business plans are the same, and
typically include an executive summary of the company as well
as a full explanation of the
company, its services, and its goods. It also defines the
approach that the organisation intends
to take in order to attain its goals and objectives. Despite the
fact that there is no such thing as
a "good" or "poor" business plan, it is
possible to categorise company plans into two
categories. The first is the traditional approach, and the second
is the lean startup approach.
According to the Small Business Administration, the basic
business plan is the most common
type of business plan that is faced by business owners. Standard
60. in that each component is
significantly more in-depth than the one before it, this version
is the most popular. There is a
great amount of additional effort required for these, and they
are frequently significantly

This chapter provides an introduction to demand and supply
concepts. Both demand and supply are defined and illustrated;
determinants of demand and supply are listed and explained.
The concept of equilibrium and the effects of changes in
demand and supply on equilibrium price and quantity are
explained and illustrated. The chapter also includes brief
discussions of efficiency (productive and allocative) and price
controls (floors and ceilings). In the Last Word, you can read
how creation of a legal market for human organs could reduce

To be part of the demand for a good, consumers have to be
willing and able to purchase the good. When deriving demand,
we are assuming that the only factor that causes consumers to
buy more or less is the price of the good. It is assumed that all
other factors that influence the amount that consumers will buy
are constant. Market demand is derived by summing the
individuals’ demand curves.

Other things equal, as price falls, the quantity demanded rises,
and as price rises, the quantity demanded falls
Explanations
Price acts as an obstacle to buyers
Law of diminishing marginal utility
64. Income effect and substitution effect
LO2
An inverse relationship exists between price and quantity
demanded. Prices act as obstacles for buyers and keep them
from being able to buy everything that they want. So, it makes
sense that with a limited income, consumers will buy more at
lower prices.
Diminishing marginal utility refers to the decrease in added
satisfaction that results as one consumes additional units of a
good or service, i.e., the second “Big Mac” yields less extra
satisfaction (or utility) than the first. Because additional units
yield less utility, the price has to be lower to make up for less
utility.
The income effect occurs as a lower price increases the
purchasing power of money income; this enables the consumer
to buy more at a lower price (or less at a higher price) without
having to reduce consumption of other goods.
The substitution effect is when a lower price gives an incentive
to substitute the lower-priced good for the now relatively
higher-priced goods.

Determinants of Demand
Determinants of demand
Change in consumer tastes and preferences
Change in the number of buyers
Change in income
Normal goods
Inferior goods
LO2
Determinants are those things that can shift the entire demand
curve causing demand to change. When most consumers
experience the same change in tastes for a particular good, the
demand for the good will change. If there is a preferable change
in tastes, demand will increase. On the other hand, if there is an
72. unfavorable change in tastes, demand will fall.
If there are more buyers in the market for a good, demand will
increase, whereas when there are fewer buyers in the market for
a good, demand will decrease.
Normal goods are goods that we buy more of as our incomes
increase. Most of the goods that we buy are normal goods. We
buy fewer normal goods when our income decreases.
Inferior goods are goods we buy more of as our income
decreases. We buy fewer inferior goods if our income increases.
*

Determinants of Demand
Change in prices of related goods
Complementary good
Substitute good
Change in consumer expectations
Future prices
Future income
LO2
Complementary goods are goods that we consume jointly. It
isn’t beneficial to have one without its complement. When the
price of one complement increases, the demand for the other
complement decreases. When the price of one complement
decreases, the demand for the other complement increases.
Some examples are cell phones and cell phone service, tuition
and textbooks.
Substitute goods are goods that we use in place of another. A
perfect substitute is a good that we use in place of the other
without any loss of satisfaction. If the price of one good
increases, the demand for its substitute increases. If the price of
one good decreases, the demand for the other substitute
73. decreases. Some examples are Colgate and Crest toothpaste,
Nike and Reebok shoes.
If consumers expect the future price of a product to be higher,
they increase their current demand for the product.
If consumers expect the future price of a product to be lower,
they decrease their current demand for the product.
If consumers expect their future income to rise, they increase
purchases now. If consumers believe their future income will be
less, they reduce their demand for some products.

Producers are willing to produce and sell more of their product
at a high price than at a low price. There is a direct relationship
between price and quantity supplied. Given product costs, a
higher price means greater profits and thus an incentive to
increase the quantity supplied. Beyond some level of output,
producers usually encounter increasing costs per added unit of

If resource prices (input prices) go up, supply decreases. If
resource prices (input prices) go down, supply increases.
If technology increases, supply increases. If we adopt, or use,
less efficient technology, supply decreases.
If the number of sellers increases, supply increases. Economic
profits in the market draw producers from less profitable
markets into this market. If the number of sellers decreases,
supply decreases. Economic losses in the market cause
producers to leave market.
If taxes are increased on a specific product, supply decreases. If
taxes are decreased, or eliminated on a specific product, supply
increases. If subsidies are increased on a specific product,
supply increases. If subsidies are decreased on a specific
product, supply decreases.
If the price of another good that the producer could produce
with the same resources rises, the supply decreases for the
product the producers are currently producing.
If the price of another good that the producer could produce
with the same resources falls, the supply increases for the
product the producers are currently producing.
If producers expect that the price of the product they are

Market Equilibrium
Equilibrium occurs where the demand curve and supply curve

Equilibrium price and equilibrium quantity
Surplus and shortage
Rationing function of prices
Efficient allocation
LO4
The equilibrium price is also known as the market-clearing
price. Graphically, note that the equilibrium price and quantity
are where the supply and demand curves intersect. It is
important to note that it is not correct to say supply equals
demand.
The rationing function of prices is the ability of competitive
forces of supply and demand to establish a price where buying
and selling decisions are coordinated.
At prices above this equilibrium, note that there is an excess
quantity supplied, or a surplus.
At prices below this equilibrium, note that there is an excess
quantity demanded, or shortage.
At equilibrium the markets are economically efficient.
*

84. Efficient Allocation
Productive efficiency
Producing goods in the least costly way
Using the best technology
Using the right mix of resources
Allocative efficiency
Producing the right mix of goods
The combination of goods most highly valued by society
LO4
Competitive markets generate productive efficiency that is the
production of any particular good in the least costly way.
Sellers that don’t achieve the least-cost combination of inputs
will be unprofitable and have difficulty competing in the
market.
The competitive process also generates allocative efficiency
which is producing the combination of goods and services most
valued by society. Allocative efficiency requires that there be
productive efficiency. Productive efficiency can occur without
allocative efficiency. Goods can be produced in the least costly
method without being the most wanted by society. Allocative
and productive efficiency occur at the equilibrium price and
quantity in a competitive market. Resources are neither over -
allocated nor under-allocated based on society’s wants.

and equilibrium quantity of 7,000 bushels of corn per week.
The shortages of corn at below-equilibrium prices (for example,
7000 bushels at $2) drive up the price. The higher prices
increase the quantity supplied and reduce the quantity demanded
until equilibrium is achieved. The surpluses caused by above-
equilibrium prices (for example, 6000 bushels at $4) push the
price down. As price drops, the quantity demanded rises and the
quantity supplied falls until equilibrium is established. At the

Government Set Prices
Price ceiling
Set below equilibrium price
Rationing problem
Black markets
Example is rent control
LO6
Price ceilings are maximum prices that can be charged on a
good. Price ceilings are set on goods that are considered to be
necessities, but the equilibrium price is so high that many
people are unable to purchase the item. To be effective, the
92. price ceiling must be set below the equilibrium price. When
price ceilings are placed on a good, this creates a chronic
shortage which makes it difficult to determine how to ration the
limited output for all of the consumers who are willing and able
to buy the good. The shortages often lead to black markets
where the good is sold at a higher price than the price ceiling.
Price ceilings distort the efficient allocation of resources.

Legal Market for Human Organs
What if we created a legal market for human organs?
Positive effects
Increase the incentive to donate
Eliminate the persistent shortage of eyes, livers, hearts,
kidneys, etc.
Organ transplants have become increasingly common, but not
everyone who needs a transplant can get one. In 2012, there
were 116,000 Americans on the waiting list for transplants. It is
estimated that there are 6,900 deaths per year in the U.S.
because not enough organs are available.
Why shortages? No market exists for human organs. The
demand curve for human organs would resemble others in that a
greater quantity would be demanded at low prices than at higher
prices. Donated organs that are rationed by a waiting list have a
zero price. The existing supply is perfectly inelastic, and there
is a fixed quantity offered by willing donors. There is a
shortage of human organs because at a zero price the quantity
demanded exceeds the quantity supplied.

95. Legal Market for Human Organs
Negative effects
Diminishes the special nature of life by commercializing it
The market would leave out the poor and uninsured
Increases the cost of medical care
Prohibition on market solution has resulted in a $1 billion
illegal market
The first negative effect is a moral objection that turning human
organs into commodities commercializes human beings and
diminishes the special nature of human life.
An analytical critique based on the elasticity of supply suggests
that the likely increase in the actual number of usable organs for
transplants would not be great. A health cost concern suggests
that a market for body organs would greatly increase the cost of
health care.
Prohibitions on a human organ market have given rise to a
worldwide, $1 billion-per-year illegal market. There is concern
that those willing to participate in an illegal market such as this
may also be willing to take extreme measures to solicit organs
from unwilling donors.
Supporters of legalizing the market for organs argue that it
would increase the supply of legal organs, drive down the price
of organs, and reduce the harvesting of organs from unwilling
sellers (the lower price would make it less profitable).

98. Economics
A social science concerned with making optimal choices under
conditions of scarcity
Economic wants exceed society’s productive capacity
LO1
If wants didn’t exceed our productive capacity, everyone could
have everything that they ever wanted and this class wouldn’t
exist. Since we can’t get everything that we want, we have to
make choices. The choices that we make are the best options
available given the circumstances. Every choice that is made
has an impact on the economy. Being in this class right now
impacts the economy.

The Economic Perspective
Economic perspective
Scarcity and choice
Opportunity cost
Purposeful behavior to increase utility
Marginal analysis
LO1
The economic perspective is the way economists view the
world. This includes considering scarcity of resources, the
opportunity costs of economic decisions, and how consumers
and businesses exhibit purposeful behavior in order to increase
their utility. Often economists use marginal analysis, which is
weighing the marginal benefits and the marginal costs of some
activity, in their work.

Scarcity and Choice
Resources are scarce
Choices must be made
Opportunity cost
There’s no free lunch
LO1
If resources weren’t scarce, we wouldn’t have to make choices.
Because we have to make choices, there is a cost to every
choice and that’s called “opportunity cost.” This is where the
phrase “There’s no such thing as a free lunch” comes from.
What did you give up to be in this class? What would you be
doing if you weren’t in class right now?
It’s important to note that everyone’s opportunity cost will be
different.

Purposeful Behavior
Rational self-interest
Individuals and utility
Firms and profit
Desired outcome
LO1
Individuals and businesses make rational decisions; decisions
that will make them better off, not worse off.
With rational self-interest, the goal is to maximize utility or
100. satisfaction. This does not mean that we are completely selfish
or that we can’t make wrong decisions. We can derive utility by
helping others and often when we make decisions, we don’t
have all of the information, so wrong decisions can be made.
Firms are rational when they make choices about which
products to produce in an attempt to maximize their profits.
People make decisions with some desired outcome in mind.

Marginal Analysis
Marginal benefit
Marginal cost
Marginal means “extra”
Comparison between marginal benefit and marginal cost
LO1
Every time we make a choice, we are weighing the marginal
benefit and cost. We will choose to do something if the
marginal benefit is greater than the marginal cost because that
is rational and will help to maximize utility.
If a person says, “That’s not worth it,” then they are saying the
marginal cost is greater than the marginal benefit.

that all variables other than those under consideration are held
constant or is assumed to not change for a particular analysis.
In economics, graphs are often used to illustrate the relationship
between variables.

Micro and Macro
Microeconomics
The study of the individual consumer, firm, or market
Macroeconomics
The study of the entire economy or a major aggregate of the
economy
LO3
In microeconomics an individual consumer, household, or
industry is examined. Examining the price of a particular
product or demand or supply of a particular products’ market is
studied in microeconomics.
In macroeconomics the entire economy is examined.
Macroeconomics also looks at the basic groups in the economy
such as all households, all businesses, all of the government, or
the foreign sector. All goods and services produced in the
economy, or the unemployment rate for the entire labor force,
or the inflation rate are all macroeconomics topics.

Normative economics is what “ought to be.” This is subjective
since everybody has different opinions about what is desirable.

The Economizing Problem
The economizing problem
Limited income and unlimited wants
The budget line
Attainable and unattainable combinations
Trade-offs and opportunity costs
LO4
The individual’s economizing problem exists because of the
combination of a limited income and unlimited wants.
A budget line is used to illustrate the greatest combinations of
two goods that can be purchased with a certain amount of
income. It reflects the greatest amount of these two goods that
can be purchased.
A budget line is created for a specific level of income so that
when income changes, the budget line will shift to show the
higher or lower incomes.

Any combination of goods inside the budget line can be
purchased, but that combination of goods is not representative
of the maximum that could be purchased. Since the blue budget
line represents the maximum of goods that can be purchased,
any point outside (to the right) of the budget line represents a
combination whose price exceeds the available income and
therefore can’t be purchased. A budget line clearly illustrates
how much of one good must be sacrificed to get more of another
good (opportunity costs).
If income increases, the budget line will shift to the right to
show that now more books and DVDs can be purchased. If
income falls, the budget line shifts to the left to show that fewer
books and DVDs can be purchased.

Society’s Economizing Problem
4 categories of economic resources
Land
Labor
Capital
Investment
Entrepreneurial ability
LO5
For the economy as a whole, the economizing problem exists
because resources are scarce.
Resources refers to inputs that are used in the production of
other goods and services.
Land refers to all natural resources.
Labor is one of the human resources and refers to all physical
and mental talents used in the production of a good or service.
Capital refers to anything man-made and used to produce goods
and services. Capital is an investment good; it is not the same
as money. Money isn’t even considered a resource.
Entrepreneurs are another type of human resource but is
different from labor mainly because entrepreneurs are risk-
