Review of x and Y axis
A graph consists of two axes called the x (horizontal/quantity) and y (vertical/price) axes.
The point where the two axes intersect is called the origin. The origin is also identified as the point (0, 0).
X axis
Moving right from the origin of (0,0), the numbers ascend. Moving left from the origin, the numbers descend.
Y axis
Moving up from the origin of (0,0), the numbers ascend. Moving down from the origin, the numbers descend.
In this course, we will mainly be using the upper right quadrant of the graphic area.
In economics it is the norm to show the independent variable on the y-axis and the dependent variable on the x-axis.

The Demand Curve
Demand Curve - A downward sloping curve that measures the relationship between the price of a good and the quantity demanded by consumers.
Demand - The amount that consumers are willing and able to purchase at various prices.
Change in Demand – A shift in the position of the demand curve that occurs in response to a change in one or more of the determinants of demand (non-price induced change).
Law of Demand – All other factors equal, the higher the price of the good or service, the lower the quantity demanded (price induced change). And the lower the price, the higher the quantity demanded. Price and Quantity Demanded vary inversely.
Change in Quantity Demanded – A change in the quantity consumers are willing and able to purchase. It is a response to a change in the market price.

Why does the demand curve shift?
The Determinants of demand
Shifts in the curve (change in demand) result from changes in one or more of the non-price determinants of demand:
Number of Consumers in the market (Size of Market)
Consumer Tastes and Preferences
Consumer Income
Prices of Related Goods (Substitute Goods and Complimentary Goods)
Expectations about the Future

The Demand Curve: Increases In Demand
Increase in Demand
Curve shifts to the right as a result of an increase in demand by the consumers (D1 to D2). This is caused by a change in one or more of the determinants of demand.
This causes Price to increase (P1 to P2). This shows a willingness to pay a higher price for all pos.

Demand and Supply Estimation
Assignment 1: Demand and Supply Estimation
Your name

Course Id:
Your Institution’s name
Date:
Imagine that you work for the maker of a leading brand of low-calorie, frozen microwavable food that estimates the following demand equation for its product using data from 26 supermarkets around the country for the month of April.
1. Compute the elasticity for each independent variable.
QD = - 5200 - 42P + 20(600) + 5.2(5500) + .20(10,000) + .25(5000)
Replacing the values of: PX= 600, I=5,500, P=500, M=5,000 and A=10,000
QD= - 5200 – 42(500) + 20(600) + 5.2(5500) + 0.20(10000) + 0.25(5000) = 17,650
Price Elasticity is given by: (Ep) = (P/Q) (∆Q/∆P)
From regression equation we find: ∆Q/∆P = -42.
Therefore, Price Elasticity (Ep) = (P/Q) (-42) (500/17650) = -1.19, likewise,
(Microwave oven’s Elasticity (EM) = (P/Q) (0.25) (5000/17650) = 0.07
Income-elasticity (EI) = (P/Q) (5.2) (5500/17650) = 1.62
Advertisement-elasticity (EA) = (P/Q) (0.20) (10000/17650) = 0.11
Cross- price elasticity ( Ec) = 20(600/17560) = 0.68
2. Determine the implications for each of the computed elasticities for the business in terms of short-term pricing strategies. Provide a rationale in which you cite your results.
Price Elasticity: The Price Elasticity (EP) is – 1.19. It implies that if there is made an increment of 1% in the cost of the item then it will drop the demanded quantity by 1.19%. In this way, it demonstrates that the demanded quantity is elastic in result. Subsequently, it prompts the circumstance that if the wages of the consumers rise then this may push them away.
Microwave Oven Elasticity: The computed elasticity in connection to the microwave ovens in the region is of 0.07, implying that this made an increase of 1% in the quantity of microwaves in the region would bring about an increment in the demanded quantity by .07%.
Income Elasticity: The calculated income elasticity is 1.62. This demonstrates that it brings an increment of 1% of the income of a buyer; it will bring an increment of the demanded quantity of the item by 1.62%. With this perception, we can see that the item is flexible; Hence, causing the organization to increase costs of the item if an income of the buyer increases.
Cross – Price Elasticity: The calculated cross – price elasticity is said to be 0.68. In the event that competitors raise their cost by 1%, it will lead to an increase of the demanded quantity of the item by 0.68%. This makes it be an inelastic behavior of the item demanded to the cost of competitors due to the fact that there are no influences in the sale of the competitors.
Advertisement Elasticity: The computed advertisement elasticity is .11; implying that if there is a 1% increment of the advertisement costs, the increment of the business would lead into an increment of the demanded quantity by 0.11%. This shows that the demanded quantity of the item is inelastic as it relates to t ...

The Demand Curve: Increases In Demand
Increase in Demand
Curve shifts to the right as a result of an increase in demand by the consumers (D1 to D2). This is caused by a change in one or more of the determinants of demand.
This causes Price to increase (P1 to P2). This shows a willingness to pay a higher price for all possible quantities of the good.
Suppliers respond to the higher price by increasing Quantity Supplied (q1 to q2) .
This process results in a new Equilibrium at e2 with Equilibrium Price P2 and Equilibrium Quantity q2.

The Demand Curve: Decreases In Demand
Decrease in Demand
Demand curve shifts to the left as a result of a decrease in demand by the consumers (D1 to D2). This is caused by a change in one or more of the determinants of demand.
This causes Price to decrease (P1 to P2). This shows a decreased willingness to pay for all possible quantities of the good.

The European Unemployment Puzzle: implications from population agingGRAPE
We study the link between the evolving age structure of the working population and unemployment. We build a large new Keynesian OLG model with a realistic age structure, labor market frictions, sticky prices, and aggregate shocks. Once calibrated to the European economy, we quantify the extent to which demographic changes over the last three decades have contributed to the decline of the unemployment rate. Our findings yield important implications for the future evolution of unemployment given the anticipated further aging of the working population in Europe. We also quantify the implications for optimal monetary policy: lowering inflation volatility becomes less costly in terms of GDP and unemployment volatility, which hints that optimal monetary policy may be more hawkish in an aging society. Finally, our results also propose a partial reversal of the European-US unemployment puzzle due to the fact that the share of young workers is expected to remain robust in the US.
Currently pi network is not tradable on binance or any other exchange because we are still in the enclosed mainnet.
Right now the only way to sell pi coins is by trading with a verified merchant.
What is a pi merchant?
A pi merchant is someone verified by pi network team and allowed to barter pi coins for goods and services.
Since pi network is not doing any pre-sale The only way exchanges like binance/huobi or crypto whales can get pi is by buying from miners. And a merchant stands in between the exchanges and the miners.

how can I sell pi coins after successfully completing KYCDOT TECH
Pi coins is not launched yet in any exchange 💱 this means it's not swappable, the current pi displaying on coin market cap is the iou version of pi. And you can learn all about that on my previous post.
RIGHT NOW THE ONLY WAY you can sell pi coins is through verified pi merchants. A pi merchant is someone who buys pi coins and resell them to exchanges and crypto whales. Looking forward to hold massive quantities of pi coins before the mainnet launch.
This is because pi network is not doing any pre-sale or ico offerings, the only way to get my coins is from buying from miners. So a merchant facilitates the transactions between the miners and these exchanges holding pi.
I and my friends has sold more than 6000 pi coins successfully with this method. I will be happy to share the contact of my personal pi merchant. The one i trade with, if you have your own merchant you can trade with them. For those who are new.

what is the future of Pi Network currency.DOT TECH
The future of the Pi cryptocurrency is uncertain, and its success will depend on several factors. Pi is a relatively new cryptocurrency that aims to be user-friendly and accessible to a wide audience. Here are a few key considerations for its future:
Message: @Pi_vendor_247 on telegram if u want to sell PI COINS.
1. Mainnet Launch: As of my last knowledge update in January 2022, Pi was still in the testnet phase. Its success will depend on a successful transition to a mainnet, where actual transactions can take place.
2. User Adoption: Pi's success will be closely tied to user adoption. The more users who join the network and actively participate, the stronger the ecosystem can become.
3. Utility and Use Cases: For a cryptocurrency to thrive, it must offer utility and practical use cases. The Pi team has talked about various applications, including peer-to-peer transactions, smart contracts, and more. The development and implementation of these features will be essential.
4. Regulatory Environment: The regulatory environment for cryptocurrencies is evolving globally. How Pi navigates and complies with regulations in various jurisdictions will significantly impact its future.
5. Technology Development: The Pi network must continue to develop and improve its technology, security, and scalability to compete with established cryptocurrencies.
6. Community Engagement: The Pi community plays a critical role in its future. Engaged users can help build trust and grow the network.
7. Monetization and Sustainability: The Pi team's monetization strategy, such as fees, partnerships, or other revenue sources, will affect its long-term sustainability.
It's essential to approach Pi or any new cryptocurrency with caution and conduct due diligence. Cryptocurrency investments involve risks, and potential rewards can be uncertain. The success and future of Pi will depend on the collective efforts of its team, community, and the broader cryptocurrency market dynamics. It's advisable to stay updated on Pi's development and follow any updates from the official Pi Network website or announcements from the team.

non-physical system or means for
bringing buyers and sellers together.
Forms of market:
1. Product market: For trading
goods and services.
2. Factor markets: For trading
factors of production e.g.
labour market
3. Stock markets: For trading
company shares e.g. NYSE
4. International financial markets:
For trading international
currencies e.g. forex market.
8. Meaning of demand
The quantity of a good or service that a
consumer is willing and able to buy at a
given price and period of time.
To be an effective demand a consumer
must have enough money to buy the
product. That is demand is not a mere
wish or desire to have a product. It must
be backed up by the ability to pay for the
product.
9. Law of Demand
The law of demand states that there is
an inverse relationship between the price
of a product and the demand for it. This
means:
As price rises, the quantity demanded
by consumers contracts, ceteris
paribus.
As price falls, the quantity demanded
by consumers extends, ceteris paribus.
10. Demand Schedule

11. Demand Curve
This is a graphical representation of the law of demand. A normal
demand curve slopes downwards to show the law of demand. This
means it has a negative slope.

22. Determinants of Demand
Price Determinant
The price of the product itself.
Non-price Determinants
1. Price of related goods e.g. the price of
complements and substitutes.
2. Consumer population.
3. Income: How income affects demand differs
for inferior and normal goods.
4. Tastes and preferences
5. Consumer population.
6. Other factors e.g. weather, government
policyhh
This causes a
movement along
the demand curve These cause a
shift of the
demand curve
23. Class Work
1. Using a demand and supply curve diagram, analyse the impact of
increased accidents in air travel on the market for air travel.
2. Using a demand and supply curve diagram, analyse the impact of a
decline in the use of robots on the market for software engineers.
24. CHANGE IN QUANTITY DEMANDED
A change in quantity demanded is just a
movement along the same demand curve. It is
when demand contracts when there is a rise in
price or extends when there is a fall in
price. The diagram below represents the two
cases of change in quantity demanded:
contraction of demand and extension of
demand. When price rises from P to P1, demand
contracts from Q to Q1 (A-B) and when price falls
from P to P2, demand extends from Q to Q2 (A-
C).
Note that a change in quantity demanded is
caused by a change ONLY in the price of the
product itself.
25. Change in Demand: Increase in demand
A rise/increase in demand
The demand curve shifts outwards
Possible causes are:
• an increase in consumer income (for normal
goods only)
• a rise in the price of substitutes
• a fall in the price of a complement
• tastes and fashion favour the product
• an increase in advertising
• a rise in the population
• other factors, e.g. hot weather increases
demand for cold drinks and sun creams
26. Change in Demand: Decrease in demand
A fall in demand
The demand curve shifts inwards
Possible causes are:
• a fall in consumer income (for normal
goods only)
• a fall in the price of substitutes
• a rise in the price of a complement
• tastes and fashion favour other products
• a reduction in advertising
• a fall in the population
• other factors, e.g. hot weather reduces the
demand for winder coats
27. Elasticity of Demand
Learning outcomes: You should be
able to define:
- Define the term, elasticity
- Define price elasticity of demand
(PED) and state the formula for its
calculation.
-Demonstrate calculations of PED.
28. Elasticity of Demand
Elasticity is a term that measures the
degree to which a variable changes
when one of its determinants changes.
We will look at two types:
1) Price Elasticity of demand (PED)
2) Income Elasticity of demand (YED).
32. Illustration
1. The price of a product rose from $2 to $3 and the quantity demanded fell from 16 to
12 units.
a) Calculate the PED coefficient and interpret your answer.
b) What type/example of product would you say the product is?
2. The quantity demanded and price of a product changed as seen in the diagram
below.
Calculate PED if price
decreased from £20 to £10
and comment on its
coefficient.
35. Price Elasticity of Demand
Learning outcomes: At the end of
this lesson, you should be able to
-Explain the determinants of PED
-Explain the relationship between
PED and Total Revenue.
36. Relationship between PED and Revenue
1. Relatively elastic demand: If the
demand for a product is price elastic,
an increase in price will reduce total
revenue and vice versa.
2. Relatively inelastic demand: If the
demand for a product is price inelastic,
an increase in price will increase total
revenue and vice-versa.
3. Unitary elastic demand: If the
demand for a product is unitary elastic,
an increase or decrease in price will
leave total revenue unchanged.
37. Determinants of PED or Factors Affecting Price Elasticity of
Demand
1. Degree of necessity of a good/service.
2. Availability of substitutes.
3. Proportion of income taken up by a good/service.
4. Time period.
38. For each question, calculate PED, interpret your answer and calculate
Total Revenue before and after the price change.
1. The price of a product rose from $2 to $3 and the quantity demanded fell
from 16 to 12 units.
2. The product’s quantity demanded rose from 10 units to 17 units when its
price fell by 10% from $80.
3. The quantity demanded and price of a product changed as seen in the
diagram below.
Price decreased from £25
to £15.

39. Price Elasticity of Demand
1. Relatively elastic demand: If the
demand for a product is price elastic,
an increase in price will reduce total
revenue and vice versa.
2. Relatively inelastic demand: If the
demand for a product is price inelastic,
an increase in price will increase total
revenue and vice-versa.
3. Unitary elastic demand: If the
demand for a product is unitary elastic,
an increase or decrease in price will
leave total revenue unchanged.
40. Price Elasticity of Demand
Learning outcomes: At the end of this
lesson, you should be able to:
Explain why PED values on a
straight line demand curve are not
constant.
Explain the difference between the
PED for primary products and
manufactured products.
41. 1. The price of a product rose from $2 to $3 and the quantity demanded fell
from 16 to 12 units.
2. The product’s quantity demanded rose from 10 units to 17 units when its
price fell by 10% from $80.
3. The quantity demanded and price of a product changed as seen in the
diagram below.
Price decreased from £25
to £15.

Starter questions: For each question, calculate PED, interpret your
answer and calculate Total Revenue before and after the price
change.
42. PEDs along a straight line demand curve
Along any downward-sloping, straight-
line demand curve, the PED varies (changes) as
we move along the curve. As the price of a
product falls, the PED along a straight-line,
downward sloping demand curve also falls.
A linear or straight line demand curve has a
unitary elasticity at the midpoint. The total
revenue is maximum at this point. Any point
above the midpoint has elasticity greater than 1,
(Ed > 1). Here, price reduction leads to an
increase in the total revenue.
The reason why PED falls when price falls on a
linear demand curve is that, consumers are more
price sensitive when product prices are higher
43. PED for Primary and Manufactured products
Primary products are goods that are available from cultivating raw
materials without a manufacturing process. Examples are wool, cotton,
wheat, fish, fruits etc.
Manufactured goods are tangible products created from the
conversion of raw materials into consumable or useful products e.g.
cars, airplanes, computers etc.
Generally primary products have relatively low PED values (inelastic),
while manufactured goods will tend to have higher values (more
elastic).
Reasons: Primary products tend to be more essential or necessary
goods that many people need and therefore have a small price
44. Price Elasticity of Demand
Learning outcomes: At the end
of this lesson, you should be
able to:
Explain the importance of PED
to firms and government.
Define income elasticity of
demand (YED) and calculate it.
45. Importance of PED in decision making by Firms and
Government
1. Producers’ knowledge of the PED for the products they sell will help
them in setting prices. If a product’s PED is elastic a reduction in
price can raise revenue while an increase in price can raise revenue
if the price of the product’s PED is inelastic. Hence, they will raise
prices for products whose demand is inelastic and reduce prices for
products with elastic demand.
2. Government will impose higher taxes on goods that are inelastic in
demand like tobacco and alcohol since consumers consume them by
habit. Raising taxes on these products can help government
increase its tax revenues. A tax raise can also help to discourage
consumption of these types of goods, since they become more
expensive for consumers. Government, on the other hand, will
reduce taxes on products with an elastic demand in order to raise its
tax revenues. Also increasing taxes on tobacco and alcohol is a good
46. Income Elasticity of Demand (YED).
Not only price affects the demand for a product. Income is also an
important determinant.
Income elasticity of demand measures the degree of responsiveness of
quantity demanded to a change in consumer income. It is measured as:
47. Range of Values for Income Elasticity of Demand (YED).
1. If the income elasticity of demand coefficient is positive, it means
the product involved is a normal good. If negative, the good is an
inferior good.
2. If the absolute value of YED is less than 1, demand is income-
inelastic. The percentage change in income is greater than the
percentage change in quantity demanded. Necessity goods (e.g.
bread) generally have low income elasticities.
3. If the absolute value of YED greater than 1, demand is income-
elastic. The percentage change in quantity demanded is greater than
the percentage change in income. Superior/luxury goods have high
income elasticity.
48. Illustration
1. Calculate the income elasticity and interpret the coefficient if incomes
increases from $10 to $15 and quantity demand falls from 20 units to
8 units as a result.
49. Income Elasticity of Demand
Learning outcomes: At the end
of this lesson, you should be
able to:
Explain what is meant by the
Engel curve.
Explain the importance of a
knowledge of YED
50. Income Elasticity of Demand
Task on Income Elasticity:
Table 1 provides information about the quantities of good A
and good B purchased by a consumer between Year 1 and
Year 2.
Table 1
Using Table 1, calculate the income elasticity of demand for good A
and good B when income increases from Year 1 to Year 2. Interpret
your results and state what type of good each is.
51. Income Elasticity of Demand
The Engel curve is a curve that shows the relationship
between consumer income and the quantity demanded
of a product over a time period. The Engel curve is
named after the German 19th century economist, Ernst
Engel (1821-96)
Task: Draw and Engel Curve for
a) a normal good.
b) an inferior good.
52. Importance of the knowledge of Income Elasticity of Demand
1. YED knowledge helps businesses plan which market to sell
their goods in. Goods with high YED usually have large
increases in demand as income levels in a country rise and so
their markets will quickly grow. Hence, firms enter markets
with large YED and avoid those with low YED. Also, if a
country is expected to go into recession, producers will plan
to produce more inferior goods as demand for inferior goods
rise with a fall in income.
2. To explain sectoral changes in the structure of an economy.
The primary sector may grow slower than the secondary and
tertiary sectors when national income rises. YED explains the
reason for this. Primary sector products are less income-
elastic than secondary-sector and tertiary-sector ones.
Consumer spending on secondary and tertiary sector
products becomes proportionally greater than that of primary
53. Demand and Price
Explain the importance of a
knowledge of YED to businesses.
Define cross elasticity of demand

their goods in. Goods with high YED usually have large
increases in demand as income levels in a country rise and so
their markets will quickly grow. Hence, firms enter markets

55. Demand and Price
Cross elasticity of demand is a measure of the degree of
responsiveness of the quantity demanded of a product X to a
change in price of a related product Y. It is computed as
56. Interpretation of Cross Elasticity Coefficient
1. Where cross elasticity of
demand is positive, the products
involved are substitutes.
2. Where cross elasticity of
demand negative, the products
involved are complements.
3. Where cross elasticity of
demand is zero, the products are
unrelated or independent.
57. Illustration

Table 1 provides information about Good X and Good Y, which are
related goods.

Good X and Good Y when the price of Good X increases. [2]
60. Exception to the law of demand/Abnormal Demand Curve
According to the law of demand, there is an inverse relationship between the
price and demand.
But there are situations where this normal relationship does not hold.
These are the cases of
a) Veblen goods or goods of ostentation or luxury goods
b) Giffen goods.
c) Expectation of future rise in price.
a) Veblen goods (named after the economist, Thorstein Veblen) are goods
that some consumers demand more of as their prices because their buyers
gain satisfaction from being seen to consume expensive goods.
b) Giffen goods (named after Robert Giffen) are necessary goods (e.g bread,
rice etc) whose demand increases as their prices increase. People may
consume less luxury items in order to purchase more Giffen goods.
c) Consumers buy more of some goods when their prices rise in order to
avoid further price rises in the future.

Topic: Demand and Price
69. Explain the implications for a country of a relatively low
income elasticity of demand for its primary products.
countries that specialize in primary products may need to diversify in
order to achieve economic growth
(relative) income for those working in the primary sector might decrease,
leading to greater inequality
as economic growth occurs, demand for primary products will increase
more slowly than the demand for secondary/tertiary products, causing the
prices of primary products to increase more slowly than the prices of
secondary/tertiary products
as economic growth occurs, there will be differences in the rate of
expansion of primary industries in relation to secondary/tertiary
industries/employment
because the prices of primary products fall relative to manufactures, the
terms of trade for countries specializing in the export of primary products
may deteriorate. This may threaten the process of economic development
as country specializes in the export of (income inelastic) goods, it will not
benefit from global economic growth (the income gap will widen), or the

93. Supply, effective supply and law of supply
Supply is the quantity of a
good/service that a supplier/producer is
willing and able to offer for sale at a
given price and period of time.
As price rises, the quantity supplied
by producers extends because
production becomes more profitable
As price falls, the quantity supplied by
producers contracts because
production becomes less profitable
A supply curve slopes upwards
Supply is effective when supply is backed up by the
ability to offer a product for sale.
Law of supply: There is a positive relationship
between price and supply i.e. the higher the price, the
higher will be the supply and vice versa.
94. Supply schedule and Supply curve
A supply schedule is a table showing the relationship between price and quantity supplied of
a product. A supply curve is a graph that shows the relationship between price and quantity
supplied. A supply curve has a positive slope i.e. it is upward sloping. Find illustrations below.

Learning outcomes: At the end of this lesson, you should
be able to:
-Define Price Elasticity of Supply (PES).
-Calculate and interpret PES values.
-Explain the determinants of PES.
120. Price Elasticity of Supply
This is defined as the degree of responsiveness of quantity supplied of a
product to a change in its price. It is calculated as follows:
123. Quick Note on Perfectly Elastic Supply
Perfectly inelastic supply (vertical supply curve)
Producers are completely price insensitive. A change in price leads to no change in supply. The idea
of a perfectly elastic supply is often seen a sporting or entertainment venue with a maximum
capacity. For example, the maximum capacity of Real Madrid Stadium is 81,044 which means the
supply of tickets is perfectly elastic at 81,044.
Quantity

81044
124. Illustration
A publishing firm realises that they can now sell their monthly magazine
for $5.50 instead of $5.00. In light of this, they increase their supply
from 240,000 to 270,000 magazines per month. Calculate the price
elasticity of the magazine and comment on your answer.
126. Determinants of PES
The determinants of PES include:
1. Unused or Spare capacity/Availability
of factors of production.
2. The mobility of factors of production.
3. Time.
4. The ability to store stock.
127. Determinants of PES
1. Unused capacity/Availability of factors of production: Where a firm has a lot of unused
capacity (significant amount of resources not fully used), it will be able to increase output
easily. PES for the product will be relatively high. However, where a firm is producing at full
capacity, it will be difficult to raise supply significantly and the product’s supply will
therefore be relatively inelastic.
2. The mobility of factors of production: Where factors of production can be easily
switched from one productive use to another, supply will tend to relatively elastic, but
supply will be relatively inelastic if it is difficult to move factors of production from one
productive use to another. For example, it may be easy to convert resources from the
production of metal cups to production of metal spoons. Thus when the price of metal
spoon rises, a firm may find it easier to increase the supply of metal spoons, which makes
the supply of metal spoons relatively elastic.
128. Determinants of PES
3. The ability to store stock: The more a firm is able to store products, the easier it is to
respond to a change in price and the more elastic the supply of the products will be if their
prices change. A low ability to store stocks will mean the supply of the stocks will be
relatively inelastic when their prices change.
4. Time: Most products have inelastic supply in the short run because most firms may not be
able to increase the quantity of all factors of production so as to increase supply
significantly when product prices rise. On the other hand, most products have elastic
supply in the long run because firms may have enough time to increase all factors of
production to raise supply significantly.

132. Differences in PES for manufactured and primary goods
1. Primary goods (e.g. cocoa) tend to have inelastic supply as a
change in price may not cause a proportionately large change in
supply. For example, a rise in the price of cocoa may not be met by
a significant proportional rise in supply because it takes a long time
to grow cocoa. Also, moving productive resources from the
production of rice, for example, to the production of cocoa may be
impossible or difficult, hence its supply ay be relatively inelastic.
2. Manufactured products, e.g. soda, on the other hand, tend to have
elastic supply as it is easier to increase or decrease quantity
supplied in response to a change in price. With manufactured
goods it is likely there will be unused capacity in the industry and
factors of production may be more mobile and it is relatively easy

LEARNING OUTCOME:
143. Meaning of Consumer Surplus and Producer Surplus
Consumer Surplus (CS)
This is the extra satisfaction (or utility) gained by consumers from paying a price that is
lower than that which they are willing to pay for. It is shown by the area under the
demand curve and above the equilibrium price. Formula:
Note: bCS and hCS stand for base and height of the consumer surplus triangles
respectively.
Producer Surplus (PS)
This is the amount of income gained by producers from receiving a price that is higher
than that which they are willing to receive. It is shown by the area under the demand
curve and above the equilibrium price. Formula:
Note: bPS and hPS stand for base and height of the producer surplus triangles
respectively.
144. Meaning of Social Surplus
Community (Social) Surplus (SS)
This is the total benefit to society of operating where market demand equals market
supply. It is the addition of consumer surplus and producer surplus.

society.
To raise government revenue for
149. Methods of Government intervention in
Markets
The use of subsidies.
The use of indirect taxes
The use of maximum price.
The use of minimum price.
150. Maximum Price
A maximum price (or price
floor) is a price set by
government below the
equilibrium price to encourage
the consumption of a product
and to make the product more
affordable for consumers.
Producers are not allowed by
law to sell above the maximum
price.
151. Analysis of a Maximum Price
The equilibrium price Pe may be
too high for consumers to afford
the product (bread). Government
then intervenes by setting a
maximum price Pmax below the
equilibrium price Pe. But at the
maximum price, quantity
demanded Q2 exceeds quantity
supplied Q1, thereby creating an
excess demand of Q1Q2.
152. Illustration
Given the demand-supply diagram for
rice in Islandia below, the government of
Islandia wants to reduce the price of rice
by in order to enable low-income
households to buy enough rice to meet
their needs. The government decides to
achieve this by imposing a maximum
price.

market/parallel market, which is
an illegal market where the
product is sold for a higher price,
somewhere between the
maximum price and the
equilibrium price.

the year respectively: June, April, September,
October and November. They spell the name Jason.
Solution to Starter: Question 1
160. RATIONING
Rationing is the controlled
distribution of goods and
services among competing
users, or an artificial restriction
of demand.
Rationing controls the size of
the ration, which is the
quantity of the limited product
that the buyer is allowed to
buy at a particular time.
161. TYPES OF RATIONING
TYPES OF RATIONING
1. Price rationing: Price rationing is a method of rationing that
allocates the limited quantities of goods and services using
markets and prices. For example, if the quantity of a given
commodity becomes increasingly limited, then the price rises.
Only the buyers most willing and able to buy the commodity, and
pay the higher price, obtain the good. The limited quantity is
automatically rationed to the highest bidder.
2. Non-price rationing: This involves rationing limited goods and
services by ways other than by price. Methods artificially designed
by humans/government are employed to ration the limited goods
and services to consumers.
163. GOVERNMENT SOLUTIONS TO EXCESS DEMAND
CREATED BY PRICE CEILINGS
In order to eliminate the excess
demand created by a maximum
price, government can increase
supply through
1. Subsidies: Government can
grant subsidies to enable firms
increase the supply of the
product.
2. Direct provision: Government
can produce and provide the
goods/services directly to
eliminate excess demand.
3. Release from storage:
Government can draw on
previously stored products to
165. Learning outcomes:
At the end of this lesson, you should be able to:
1
Define minimum price and
explain why government sets
minimum prices.
2
Analyse the impact of
minimum prices on markets
3
Discuss the interventions
used in minimum price
legislation
166. Minimum Price
(Price Floor)
A minimum price is a price
set by the government
above the equilibrium price
to increase the supply of a
product and ensure that the
producers make a decent
profit from its sale.
167. Reasons for setting minimum prices (price floors)
Government can set minimum prices to:
1. Raise the incomes for producers of goods and services that government
thinks are important e.g. agricultural products which are subject to large
price fluctuations.
2. Protect workers by setting a minimum wage so they can earn enough to
meet their needs and wants reasonably well.
3. Discourage the consumption of harmful products (e.g. alcohol and
tobacco) by pricing them above what many can afford.
168. Effects of a price floor
1. A surplus (excess supply)
of Q1Q2 is created.
2. Producers may try to get
around the price floor by
selling at a lower price: a
price between the price
floor (PMin) and the
equilibrium price (Pe)
169. Government intervention to control excess
demand supply at the price floor
1. Government can buy up the surplus at the minimum price
so that the demand curve shifts to the right to
D+government buying. This eliminates the surplus. The
government then stores the surplus, destroys it or sells it
abroad. But buying and storing the surplus is expensive and
has opportunity costs, destroying it is wasteful and selling it
abroad may amount to dumping.
2. Producers may be limited by quotas so they do not supply
beyond Q1. But this means only a limited number of
producers will benefit from the minimum price.
3. Government can attempt to increase the demand for the
product by advertising it or by restricting imports (through
protectionism) of the same products so that domestic
demand for it will increase.
170. Minimum Price
(Price Floor)
A minimum price is a price
set by the government
above the equilibrium price
to increase the supply of a
product and ensure that the
producers make a decent
profit from its sale.
171. Government Intervention in Markets
(Subsidies)
Learning outcomes
You should be able to:
- Define a subsidy and explain why government grants
it.
- Demonstrate subsidy grants graphically and calculate
it.
172. Meaning and reasons for subsidies
A subsidy is an amount paid by government to a firm, per unit
of output, to encourage the production of a product.
The reasons why government grants subsidies include:
1. To reduce the price of essential goods (e.g. rice) so as to encourage its
consumption.
2. To guarantee the supply of products of strategic importance to the economy e.g.
basic food supply and power source like coal.
3. To enable producers to compete with overseas trade, thereby protecting the home
industry.
173. Subsidy and the Supply Curve
If a subsidy is granted to a firm on a
certain product, the supply curve for
the product will shift vertically
downwards by the amount of the
subsidy, because it reduces the cost
of production. If a subsidy of $2 per
unit is granted, the supply curve will
shift to the right as seen below.

INDIRECT TAX WORKS
Learning outcomes: At the end of this lesson,
you should be able to
176. An indirect tax is a tax imposed
on expenditure on goods and
services. Examples include:
Goods and Services Tax (GST)
Value Added Tax
Consumption tax
Excise tax
Indirect Tax
177. REASONS FOR IMPOSING INDIRECT TAXES
1. To raise revenue needed to carry out state
responsibilities.
2. To discourage the consumption of
dangerous/demerit goods.
3. To redistribute income in order to reduce income
inequality.
4. To preserve and protect the environment e.g.
pollution tax.
5. To reduce balance of payments deficits.
178. How Indirect Taxes Work
An indirect tax is imposed on the selling price of a
product, thereby raising the firm’s costs and shifting the
supply curve for the products vertically upwards by the
amount of the tax. Because of this shift, less of the
product is supplied at every price.
181. Government Intervention in markets: Indirect
Tax
Learning outcomes: At the end of this lesson, you should be able to:
1. EXPLAIN THE IMPACT OF INDIRECT
TAXES ON STAKEHOLDERS
3. PERFORM CALCULATIONS ON
THE IMPACT OF INDIRECT
TAXES
3. EXPLAIN HOW THE TAX
BURDEN IS SHARED BETWEEN
CONSUMERS AND
PRODUCERS
183. Graphical Analysis of Indirect Tax
Notes:
1. The price Pe is received by producers and also paid by consumers before the tax.
2. A specific tax of $XY per unit is charged. Hence the supply curve shifts vertically upwards by the
amount $XY. The quantity demanded and supplied falls from Qe to Q1
3. Following the tax, the amount received by producers then falls from Pe to C and the amount paid by
consumers rises from Pe to P1.
4. Producers receive the price $C per unit and consumers pay the price P1 after the tax is imposed.
Producers pay CPe to government and consumers pay to PeP1 to government as tax.
187. Demand and Supply: a revisit
Learning outcomes: You should be able to:
- To explain the reasons for a downward sloping demand curve.
- Define the price mechanism and explain its functions.
188. Reasons for downward sloping demand curve
There is an inverse relationship between the demand for a product and its price for
the following reasons:
1. Income effect.
2. Substitution effect
189. Reasons for downward sloping demand curve
Income effect: There will be an increase in the real income of consumers when
the price of a good/service falls and vice-versa. That is consumers will be able to
buy a higher quantity of a product when the price falls. For example, a consumer
with an income of $30 can buy 15 apples priced at $2 each. If the price of each
apple falls to $1.50, the consumer’s real income will increase as they will be able to
now buy 20 apples.
Substitution Effect: When the price of a product rises, it is likely that consumers
will substitute it for a relatively cheaper alternative product whose price has
remained the same. Also when price falls, consumers tend to substitute other
relatively more expensive products for the product whose price falls. Moreover, if
we link utility (satisfaction derived from consuming products) with product
consumption and a product’s price increases, this means the utils (measurement of
utility in units) from the product is the same but the product is more expensive.
Consumers will therefore tend to switch their purchases to a relatively cheaper
substitute that gives them utils that correspond to the price they pay for it.
190. The price mechanism is the means by which decisions of consumers
and businesses interact to determine the allocation of resources.
The free-market price mechanism clearly does not ensure an
equitable distribution of resources and can lead to market failure.
The price mechanism performs (3) three functions (SIR):
1) Signalling function
2) Incentive function
3) Rationing function
Price Mechanism
191. Functions of the Price Mechanism
1. Signalling function
Prices perform a signalling function – i.e. they adjust to demonstrate where
resources are required.
Prices rise and fall to reflect scarcities and surpluses.
If prices are rising because of high demand from consumers, this is a signal to
suppliers to expand production to meet the higher demand.
If there is excess supply in a market, the price mechanism will help to eliminate a
surplus of a good by allowing the market price to fall.
2. Incentive function
Through choices consumers send information to producers about their changing
nature of needs and wants.
One important feature of a free-market system is that decision-making
is decentralised, i.e. there is no single body responsible for deciding what to
produce and in what quantities.
This is in contrast to a planned (state-controlled) economic system where there is
192. Functions of the Price Mechanism
3. Rationing function
Prices ration scarce resources when demand outstrips supply.
When there is a shortage, price is bid up – leaving only those
with willingness and ability to pay to buy.
.
193. Demand and Supply: a revisit
Learning outcomes: You should be able to :
- explain why the supply curve is upward sloping.
194. Reasons for the downward sloping nature of the Supply
Curve
Three factors responsible for the shape of the supply curve or the law of supply:
1. The short run.
2. The law of diminishing marginal utility.
3. Increasing marginal costs.
195. Reasons for the upward sloping nature of the Supply Curve
1. The short run.
The short run is a production period too short to vary all factors of production. At least one
factor of production is fixed in the short run. In the short run, firms are not able to change
all their factors of production to increase or decrease supply when product prices change.
Capital and land may be fixed while labour may be variable.
2. The law of diminishing returns.
This law states that as more variable factors of production continue to be added to a fixed
factor of production, additional units of output (called marginal product) increases at first but
eventually declines.
3. Increasing marginal costs.
Marginal cost is the additional cost associated with producing an extra unit of output. This
cost starts to increase when diminishing returns set in due to inefficiency in production.
Therefore, to encourage firms to produce more, price must rise high enough to cover the
additional cost of production.
196. How the Law of Diminishing returns works
1. Total Product (TP)
This is the total output produced by a firm using its fixed and variable inputs in a time period.
2. Average Product (AP)
This is the output product by each unit of variable input employed. It is calculated as
3. Marginal Product (MP)
This is the additional output produced by a firm by using an extra unit of a variable input.
This is calculated as
