What do the Grade 9 Economics cards cover?

31 cards across 8 chapters of the national textbook: Introducing Economics, The Basic Economic Problems and Economic Systems, Economic Resources and Markerts, Introduction to Demand and Supply, Introduction to Production and Cost, Introduction to Money, Introduction to Macroeconomics and Basic Entrepreneurship. You can take any chapter one card at a time on the page itself.

Is there a national exam in Grade 9?

No. Ethiopia sets national exams in Grade 6, Grade 8 and Grade 12 only. These cards are for your school's own exams, and for the national exam that comes a few years later.

Where do these cards come from?

They are drafted from Grade 9 Economics, the Ministry of Education textbook for this grade. A second pass that cannot see the chapter then re-derives every formula, constant and table row, and anything it cannot confirm is held back instead of published.

Yes. Every card here is free to read and the printable sheet is free to download. Neither needs an account.

When was this last checked?

30 August 2026. Cards arrive chapter by chapter, and the line under each one says when that card was last read through.

Introducing Economics

Decision Making Units in an EconomyReference tableHouseholds · Business Firms · Government

Decision Making Unit	Primary Role	Income Source
Households	Own factors of production and consume goods	Rent, wages, interest, profit
Business Firms	Hire factor services and produce commodities	Revenue from sales of goods and services
Government	Provide public services and regulate	Direct and indirect taxes

When you use it

Use when identifying the three basic economic agents, their roles, and their income mechanisms.

Watch out

Government enterprises that produce market goods are classified under business firms, not under general government.

Deductive and Inductive MethodsRule

When you use it

Use when determining the logical reasoning method applied to formulate economic theories.

Watch out

Deductive reasoning moves from general principles to specific facts. Inductive reasoning moves from specific observations to general principles.

Microeconomics vs MacroeconomicsReference tableScope · Central problem · Main tools · +1

Feature	Microeconomics	Macroeconomics
Scope	Individual units (households, firms)	Economy as a whole (aggregates)
Central problem	Price determination and resource allocation	Level of income and employment
Main tools	Demand and supply of particular goods	Aggregate demand and aggregate supply
Examples	Price of teff, individual income	GDP of Ethiopia, general price level

When you use it

Use when identifying the scope, analytical tools, or core problem of an economic scenario.

Watch out

Microeconomics studies individual markets and price determination, while macroeconomics examines national aggregates and full employment.

Positive vs Normative EconomicsCommon mistake

When you use it

Use when distinguishing factual descriptions from opinion-based or value-laden economic claims.

Watch out

A positive statement is testable against facts even if it is factually incorrect. Normative statements express value judgments using words like should or ought to and cannot be verified by data.

The Basic Economic Problems and Economic Systems

Comparison of Economic SystemsReference tableTraditional economy · Capitalist economy · Command economy · +1

Economic System	Ownership of Resources	Allocation Mechanism
Traditional economy	Family or tribe	Customs, traditions, and barter
Capitalist economy	Private ownership	Price mechanism, competition, and profit motive
Command economy	State or collective	Central economic planning
Mixed economy	Private and public sectors	Market forces combined with government planning

When you use it

Use when comparing how different economic systems determine resource ownership and economic decisions.

Watch out

Private ownership is completely absent in a command economy, but it co-exists with public ownership in a mixed economy.

Opportunity Cost CalculationFormula

\text{Opportunity Cost} = \left| \frac{\Delta \text{Sacrificed Output}}{\Delta \text{Gained Output}} \right|

\text{Opportunity Cost} = \left| \frac{\Delta \text{Sacrificed Output}}{\Delta \text{Gained Output}} \right|

$\Delta \text{Sacrificed Output}$: Quantity of the good given up $units$
$\Delta \text{Gained Output}$: Quantity of the additional good obtained $units$

When you use it

Use when calculating the trade-off of producing more of one good in terms of the forgone good on the PPF.

Watch out

Opportunity cost is measured in physical units of the sacrificed good, not in money. Always take the absolute value.

Production Possibilities Frontier PointsReference tableOn the curve · Inside the curve · Outside the curve

Position	Status	Economic Meaning
On the curve	Attainable and efficient	Full employment and optimal resource utilisation
Inside the curve	Attainable but inefficient	Underutilised resources or unemployment
Outside the curve	Unattainable	Beyond current resources and technology capacity

When you use it

Use to interpret efficiency and output feasibility for any combination of goods on a PPF diagram.

Watch out

Points inside the curve can be produced, but they indicate idle resources or inefficient production.

Scarcity versus ShortageCommon mistake

When you use it

Use when distinguishing between the universal economic condition and a temporary market imbalance.

Watch out

Scarcity is permanent, universal, and occurs when resources are limited at zero price. Shortage is temporary and occurs only at the prevailing market price.

Drafted from Grade 9 Economics, pages 13-28, then checked twice before it went up

Three Central Economic ProblemsReference tableAllocation of resources · Choice of technique · Distribution of output

Problem	Core Question	Decision Focus
Allocation of resources	What to produce?	Types and quantities of goods (capital vs consumption)
Choice of technique	How to produce?	Labour-intensive vs capital-intensive production methods
Distribution of output	For whom to produce?	Distribution of goods among members of society

When you use it

Use when identifying the three fundamental questions every economy must answer due to resource scarcity.

Watch out

How to produce is strictly about the choice of production technique (labour vs capital), not about final distribution.

Economic Resources and Markerts

Agricultural Soil Types of Ethiopian HighlandsReference tableRed to reddish brown soils · Brownish to grey and black soils

Soil Type	Characteristics	Agricultural Potential
Red to reddish brown soils	Friable and good drainage	Well endowed with minerals for crops
Brownish to grey and black soils	High clay content	Excellent potential with proper drainage

When you use it

Use this to distinguish the two dominant agricultural soil types found in the Ethiopian highlands.

Watch out

Black clay soils require proper drainage and conditioning to realize their potential, unlike naturally well drained red soils.

Direction of Flows in the Circular Flow ModelCommon mistake

When you use it

Use this when analyzing transactions between households and business firms in circular flow diagrams.

Watch out

Real flows and money flows move in opposite directions. For goods, the real flow moves from firms to households, while the money flow moves from households to firms.

Factors of Production and Factor PaymentsReference tableLand · Labour · Capital · +1

Factor of Production	Factor Payment	Description
Land	Rent	Gifts of nature and natural resources
Labour	Wage	Physical and mental human effort
Capital	Interest	Manufactured inputs like machinery
Entrepreneurship	Profit	Organizing inputs and taking business risk

When you use it

Use this table to match each economic resource with its corresponding factor reward or definition.

Watch out

Capital earns interest, not profit. Profit is the reward exclusively for entrepreneurship.

Introduction to Demand and Supply

Confusing Stock with SupplyCommon mistake

When you use it

Reach for this card when defining supply to ensure it is not equated with the total inventory of a firm.

Watch out

Stock is the total stored output. Supply is only the specific quantity sellers are willing and able to offer at a given price.

Drafted from Grade 9 Economics, pages 45-61, then checked twice before it went up

Demand Function and Law of DemandFormula

Q_d = f(P)

Q_d = f(P)

$Q_d$: Quantity Demanded $kg$
$P$: Price $Birr$

When you use it

Use this when analyzing how Quantity Demanded changes inversely with Price under the ceteris paribus condition.

Watch out

Demand requires both willingness and ability to pay. A mere desire without purchasing power is not economic demand.

Drafted from Grade 9 Economics, pages 45-61, then checked twice before it went up

Market Equilibrium and ImbalancesReference tableEquilibrium · Excess Demand · Excess Supply

Market State	Condition	Price Direction
Equilibrium	$Q_d = Q_s$	Stable
Excess Demand	$Q_d > Q_s$	Rises
Excess Supply	$Q_s > Q_d$	Falls

When you use it

Use this to identify whether a market is in balance, facing a shortage, or holding a surplus at a given price.

Watch out

In excess demand, buyer competition pushes the price upward toward equilibrium, not downward.

Drafted from Grade 9 Economics, pages 45-61, then checked twice before it went up

Supply Function and Law of SupplyFormula

Q_s = f(P)

Q_s = f(P)

$Q_s$: Quantity Supplied $kg$
$P$: Price $Birr$

When you use it

Use this to describe the direct or positive relationship between Price and Quantity Supplied, ceteris paribus.

Watch out

Supply curves slope upward to the right because higher prices give producers an incentive to supply more.

Introduction to Production and Cost

Economic CostFormula

\text{Economic Cost} = \text{Explicit Cost} + \text{Implicit Cost}

\text{Economic Cost} = \text{Explicit Cost} + \text{Implicit Cost}

$\text{Economic Cost}$: Total economic opportunity cost $Birr$
$\text{Explicit Cost}$: Actual monetary out-of-pocket payments to resource suppliers $Birr$
$\text{Implicit Cost}$: Estimated value of self-owned resources used in production $Birr$

When you use it

Use this relationship to determine total economic cost by including both direct cash expenses and the opportunity cost of owned resources.

Watch out

Accounting cost only measures explicit costs. Economic cost always includes implicit costs such as forgone rent or owner salary.

Product Curve RelationshipsReference tableMP > AP · MP = AP · MP < AP · +2

Condition	Behavior of Product Curves
$MP > AP$	$AP$ is rising
$MP = AP$	$AP$ is at its maximum
$MP < AP$	$AP$ is falling
$MP = 0$	$TP$ is at its maximum
$MP < 0$	$TP$ is declining

When you use it

Use this reference to identify how Total Product and Average Product behave based on the value of Marginal Product.

Watch out

Average Product reaches its maximum when Marginal Product equals Average Product, not when Marginal Product reaches its own maximum.

Drafted from Grade 9 Economics, pages 62-76, then checked twice before it went up

Short Run Total CostFormula

TC = TFC + TVC

TC = TFC + TVC

$TC$: Total cost of production $Birr$
$TFC$: Total fixed cost that does not change with output $Birr$
$TVC$: Total variable cost that changes with output $Birr$

When you use it

Use this formula to calculate the total cost incurred by a firm in the short run from its fixed and variable components.

Watch out

Total fixed cost is incurred even when output is zero, so total cost equals total fixed cost at zero output.

Introduction to Money

Composition of Money SupplyReference tableCurrency with the public · Deposit money with the public · Total Money Supply

Component	Constituents	Deductions
Currency with the public	Currency notes in circulation, birr notes and coins, small coins	Cash in hand with banks
Deposit money with the public	Bank balances held in current accounts (chequable deposits)	None
Total Money Supply	Currency with the public + Deposit money with the public	None

When you use it

Use when evaluating the total stock of money in an economy or determining currency with the public.

Watch out

Cash in hand with banks must be deducted from total currency circulation to get currency with the public.

Criteria for Acceptance as MoneyReference tableStandardization · Acceptability · Divisibility · +2

Criterion	Requirement
Standardization	Must be easily standardized to make value ascertainment simple
Acceptability	Must be widely accepted as a medium of economic exchange
Divisibility	Must be divisible so that it is easy to make change
Portability	Must be light and easy to carry around
Durability	Must not degrade or deteriorate quickly over time

When you use it

Use when identifying the physical and economic properties a commodity must possess to serve as money.

Watch out

A commodity must satisfy all five criteria simultaneously to function effectively as money.

Four Functions of MoneyReference tableMedium of exchange · Unit of account · Store of value · +1

Function	Economic Role
Medium of exchange	Eliminates double coincidence of wants, lowers transaction costs
Unit of account	Measures and expresses the value of goods and services
Store of value	Transfers purchasing power from the present to the future
Standard of deferred payments	Facilitates lending, borrowing, and settling future payments

When you use it

Use when analyzing how money operates in an economy or differentiating its primary roles.

Watch out

Money is not unique as a store of value since assets like land or bonds also store value, but money has the highest liquidity.

Drafted from Grade 9 Economics, pages 77-92, then checked twice before it went up

Keynesian Motives for Demanding MoneyReference tableIncome motive (Transaction) · Business motive (Transaction) · Precautionary motive · +1

Motive	Main Purpose	Key Determinant
Income motive (Transaction)	To bridge the gap between receipt of income and daily expenditure	Income level and payment frequency
Business motive (Transaction)	To pay for wages, materials, and current operating costs	Volume of business turnover
Precautionary motive	To hold cash balances for unforeseen risks and contingencies	Individual nature and living conditions
Speculative motive	To take advantage of future changes in interest rates and bond prices	Expected market interest rates

When you use it

Use when describing liquidity preference or explaining why individuals and firms hold cash balances.

Watch out

The transaction motive consists of two distinct components: the income motive for households and the business motive for firms.

Drafted from Grade 9 Economics, pages 77-92, then checked twice before it went up

Limitations of the Barter SystemReference tableLack of double coincidence of wants · Lack of a common measure of value · Indivisibility of commodities · +2

Limitation	Description
Lack of double coincidence of wants	Requires finding a partner who wants what you have and has what you want
Lack of a common measure of value	Absence of a common standard to determine exchange ratios between goods
Indivisibility of commodities	Certain goods lose value or identity when divided to make an exchange
Difficulty in storing and transferring wealth	Goods deteriorate over time, incur high storage costs, or are costly to transport
Difficulty in deferred payments	Future payments in goods are hindered by price instability and quality variation

When you use it

Use when explaining why direct exchange of goods fails and why monetary systems emerged.

Watch out

Do not confuse indivisibility of goods with difficulty in storing wealth.

Introduction to Macroeconomics

Demand-Pull vs Cost-Push InflationReference tableDemand-pull inflation · Cost-push inflation

Inflation Type	Primary Cause	Key Feature
Demand-pull inflation	Increase in aggregate demand	Too much money chasing too few goods near full capacity
Cost-push inflation	Decrease in aggregate supply	Rising input costs, higher wages, or production setbacks

When you use it

Use this table to distinguish between inflation driven by excess aggregate demand and inflation caused by supply side cost increases.

Watch out

Demand-pull inflation arises from the demand side (too much spending), whereas cost-push inflation arises from supply side cost shocks.

GNP and GDP RelationshipFormula

\text{GNP} = \text{GDP} + \text{NFI}

\text{GNP} = \text{GDP} + \text{NFI}

$\text{GNP}$: Gross National Product $\text{ETB}$
$\text{GDP}$: Gross Domestic Product $\text{ETB}$
$\text{NFI}$: Net factor income from foreign sources $\text{ETB}$

When you use it

Use this formula to calculate Gross National Product by adjusting GDP with net factor income from abroad.

Watch out

NFI is negative when factor income paid to foreigners abroad exceeds factor income received from abroad, which makes GNP smaller than GDP.

Drafted from Grade 9 Economics, pages 93-104, then checked twice before it went up

Intermediate Goods in GDPCommon mistake

When you use it

Reach for this when determining which goods and services are included in GDP calculations.

Watch out

Do not include intermediate goods in GDP calculations. Only final goods and services produced currently within national borders are counted, avoiding double counting.

Drafted from Grade 9 Economics, pages 93-104, then checked twice before it went up

Real GDPFormula

\text{Real GDP} = \frac{\text{Nominal GDP}}{\text{Price Index}} \times 100

\text{Real GDP} = \frac{\text{Nominal GDP}}{\text{Price Index}} \times 100

$\text{Real GDP}$: Gross Domestic Product measured at constant prices $\text{ETB}$
$\text{Nominal GDP}$: Gross Domestic Product measured at current prices $\text{ETB}$
$\text{Price Index}$: Average measure of price level changes $\text{dimensionless}$

When you use it

Use this formula to remove the effect of price changes from Nominal GDP and calculate real output at constant prices.

Watch out

Always divide Nominal GDP by the Price Index first, then multiply the quotient by 100.

Types of UnemploymentReference tableFrictional unemployment · Structural unemployment · Cyclical unemployment

Unemployment Type	Primary Cause
Frictional unemployment	Temporary job transition, seasonality, or new entrants seeking employment
Structural unemployment	Mismatch between worker skills or location and employer requirements
Cyclical unemployment	Deficiency in aggregate demand during economic recessions or downturns

When you use it

Use this reference table to classify different forms of unemployment based on their underlying economic cause.

Watch out

Do not confuse structural unemployment (skill mismatch) with cyclical unemployment (shortage of aggregate demand during recessions).

Basic Entrepreneurship

Creativity to Entrepreneurship FlowRule

When you use it

Use to explain the progression from idea generation to commercial business activity.

Watch out

Creativity is the ability to generate new ideas, innovation is applying those ideas to solve problems, and entrepreneurship is the commercial process of taking risks to launch the enterprise.

Drafted from Grade 9 Economics, page 105 onwards, then checked twice before it went up

Financial Budgetary RequirementsReference tablePermanent Capital · Working Capital · Asset Finance

Capital Type	Term	Primary Purpose
Permanent Capital	Long term	Start-up costs, major developments, and expansions
Working Capital	Short term	Raw materials, operating costs, and short-lived assets
Asset Finance	Medium to long term	Purchase of physical assets like machinery and buildings

When you use it

Use to differentiate between the capital needs of a new or growing business.

Watch out

Working capital is short term financing for day to day operations, not for purchasing permanent machinery.
