What do the Grade 12 Economics cards cover?

34 cards across 8 chapters of the national textbook: The fundamental concepts of macroeconomics introduction, Aggregate demand and aggregate supply analysis, Market failure and consumer protection introduction, Macroeconomic policy instruments introduction, Tax theory and practice introduction, Poverty and inequality, Macroeconomic Reforms in Ethiopia and Economy, Environment and Climate Change. You can take any chapter one card at a time on the page itself.

Do these help with the Grade 12 national exam?

Yes. Grade 12 sits a national exam, and these are the Economics rules and formulas it expects you to know. Past papers with a worked answer behind every question are on the same site, also free.

Where do these cards come from?

They are drafted from Grade 12 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?

The fundamental concepts of macroeconomics introduction

Dividing Unemployed by Total PopulationCommon mistake

When you use it

Use when checking calculated unemployment rates from census or demographic questions.

Watch out

Do not divide unemployed persons by the total population or working-age population. The denominator must be the Labour Force (Employed + Unemployed).

Inflation Rate from CPIFormula

\text{Inflation Rate} = \frac{\text{CPI}_2 - \text{CPI}_1}{\text{CPI}_1} \times 100

\text{Inflation Rate} = \frac{\text{CPI}_2 - \text{CPI}_1}{\text{CPI}_1} \times 100

$\text{Inflation Rate}$: Percentage change in general price level $\%$
$\text{CPI}_2$: Consumer price index in the current period $\text{dimensionless}$
$\text{CPI}_1$: Consumer price index in the base or previous period $\text{dimensionless}$

When you use it

Use when finding the annual or periodic rate of price inflation or deflation from Consumer Price Indices.

Watch out

Always divide by the past period index CPI_1, not the current index CPI_2. A negative result means deflation.

Major Schools of Macroeconomic AnalysisReference tableClassical · Keynesian · Monetarist

School of Thought	Key Driver of Economy	Price Behavior	Policy Prescription
Classical	Aggregate supply	Fully flexible	Hands off, market self corrects
Keynesian	Aggregate demand	Sticky wages and prices	Active fiscal policy
Monetarist	Money supply	Flexible in long run	Control money supply growth

When you use it

Use to distinguish the core assumptions and recommended government interventions across macroeconomic schools.

Watch out

Keynesians prioritize fiscal policy due to sticky prices, whereas Monetarists view fiscal expansion as merely crowding out private investment.

Relationship between GDP and GNPFormula

\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 received from abroad $\text{ETB}$

When you use it

Use to convert Gross Domestic Product to Gross National Product using net receipts from abroad.

Watch out

NFI can be negative if factor income paid to foreigners exceeds factor income earned abroad by citizens.

Unemployment RateFormula

\text{Unemployment Rate} = \frac{\text{Unemployed}}{\text{Labour Force}} \times 100

\text{Unemployment Rate} = \frac{\text{Unemployed}}{\text{Labour Force}} \times 100

$\text{Unemployment Rate}$: Percentage of the labour force that is jobless $\%$
$\text{Unemployed}$: Number of job seekers without work $\text{people}$
$\text{Labour Force}$: Total number of employed and unemployed individuals $\text{people}$

When you use it

Use when determining the proportion of the labour force actively looking for work but lacking employment.

Watch out

Do not include people outside the labour force like full-time students, retirees, or children in the denominator.

Aggregate demand and aggregate supply analysis

Aggregate Supply Curve TypesReference tableKeynesian Aggregate Supply · Short-Run Aggregate Supply (SRAS) · Long-Run / Classical Supply (LRAS)

Supply Horizon	Curve Slope	Key Assumption
Keynesian Aggregate Supply	Horizontal	Widespread unemployment and rigid wages allow output expansion at constant prices
Short-Run Aggregate Supply (SRAS)	Upward sloping	Sticky wages and worker misperceptions cause output to respond positively to price level
Long-Run / Classical Supply (LRAS)	Vertical	Fully flexible prices and wages ensure the economy produces at natural real GDP ( $Q_N$ )

When you use it

Use when identifying the differences between Keynesian, short-run, and long-run classical aggregate supply curves.

Watch out

The vertical LRAS curve is positioned strictly at natural real GDP, meaning price level changes in the long run have zero effect on real output.

Drafted from Grade 12 Economics, pages 26-48, then checked twice before it went up

Components of Aggregate DemandFormula

AD = C + I + G + (X - M)

AD = C + I + G + (X - M)

$AD$: Aggregate demand $\text{ETB}$
$C$: Consumption expenditure by households $\text{ETB}$
$I$: Private Investment spending $\text{ETB}$
$G$: Government Purchases of goods and services $\text{ETB}$
$X$: Exports value $\text{ETB}$
$M$: Imports value $\text{ETB}$

When you use it

Use when calculating total aggregate demand or evaluating how a change in any macroeconomic sector spending affects aggregate demand.

Watch out

Do not add imports. Net exports is exports minus imports, so an increase in imports reduces aggregate demand.

Drafted from Grade 12 Economics, pages 26-48, then checked twice before it went up

Movement Along Curve versus Shift of CurveCommon mistake

When you use it

Use when determining whether an economic event causes a movement along the AD or AS curve or shifts the entire curve.

Watch out

A change in the general price level ONLY causes a movement along the existing AD or AS curve (change in quantity demanded or supplied). Non-price factors such as taxes, input costs, and money supply shift the entire curve.

Drafted from Grade 12 Economics, pages 26-48, then checked twice before it went up

Real WageFormula

W_r = \frac{W}{P}

W_r = \frac{W}{P}

$W_r$: Real wage $\text{ETB}$
$W$: Nominal wage $\text{ETB}$
$P$: Price level index $\text{dimensionless}$

When you use it

Use when determining the purchasing power of wages or explaining why sticky wages make the short-run aggregate supply curve slope upward.

Watch out

When the price level falls while nominal wage is locked by contract, the real wage rises, which causes firms to hire fewer workers and reduce output.

Drafted from Grade 12 Economics, pages 26-48, then checked twice before it went up

Market failure and consumer protection introduction

Adverse Selection vs Moral HazardCommon mistake

When you use it

Use this when distinguishing between types of asymmetric information problems in markets.

Watch out

Do not confuse the timing. Adverse selection is hidden information occurring before the transaction, while moral hazard is hidden action occurring after the contract is signed.

Drafted from Grade 12 Economics, pages 49-71, then checked twice before it went up

Classification of GoodsReference tablePure private goods · Pure public goods · Impure public (toll) · +1

Good Type	Rivalry	Excludability	Example
Pure private goods	Rivalrous	Excludable	Food, clothing
Pure public goods	Non-rivalrous	Non-excludable	National defence, clean air
Impure public (toll)	Non-rivalrous	Excludable	Toll express roads, cable TV
Impure public (common)	Rivalrous	Non-excludable	Ocean fish, shared grazing

When you use it

Use this table to classify economic goods based on rivalry and excludability criteria.

Watch out

Pure public goods require both non-rivalry and non-excludability. Goods possessing only one characteristic are impure public goods.

Drafted from Grade 12 Economics, pages 49-71, then checked twice before it went up

Externality and Allocative EfficiencyRule

When you use it

Use this rule to determine the direction of market failure and corrective policies for external effects.

Watch out

Negative externalities lead to overproduction where MSC exceeds MPC, requiring a per unit tax. Positive externalities lead to underproduction where MSB exceeds MPB, requiring a per unit subsidy.

Drafted from Grade 12 Economics, pages 49-71, then checked twice before it went up

Macroeconomic policy instruments introduction

Exchange Rate Regimes and TermsReference tableFixed Exchange Rate · Flexible Exchange Rate

Exchange Rate Regime	Currency Value Fall	Currency Value Rise	Determining Mechanism
Fixed Exchange Rate	Devaluation	Revaluation	Government decision
Flexible Exchange Rate	Depreciation	Appreciation	Market supply and demand

When you use it

Use when classifying foreign exchange rate changes by system type and distinguishing market movements from policy decisions.

Watch out

Devaluation and revaluation occur under fixed exchange rates by government decree, whereas depreciation and appreciation occur under floating regimes through market forces.

Fiscal and Monetary Policy ToolsReference tableFiscal: Government Spending · Fiscal: Taxation · Monetary: Discount Rate · +2

Policy Instrument	Expansionary Action	Contractionary Action
Fiscal: Government Spending	Increase spending	Decrease spending
Fiscal: Taxation	Reduce taxes	Increase taxes
Monetary: Discount Rate	Lower discount rate	Raise discount rate
Monetary: Open Market Operations	Buy government securities	Sell government securities
Monetary: Required Reserve Ratio	Lower reserve ratio	Increase reserve ratio

When you use it

Use when deciding which macroeconomic policy actions shift aggregate demand to manage recession or inflation.

Watch out

Expansionary policy combats unemployment during a recession, while contractionary policy combats high inflation during economic overheating.

Price Control Placement ErrorCommon mistake

When you use it

Use when identifying whether a price ceiling or floor causes a market imbalance.

Watch out

A price ceiling placed above equilibrium or a price floor placed below equilibrium is non-binding and has zero effect on market price and quantity.

Drafted from Grade 12 Economics, pages 72-102, then checked twice before it went up

Price ControlsReference tablePrice Ceiling · Price Floor

Control Type	Legal Limit Position	Market Effect
Price Ceiling	Below equilibrium price	Shortage (Excess demand)
Price Floor	Above equilibrium price	Surplus (Excess supply)

When you use it

Use when evaluating the market impacts of legally imposed maximum or minimum prices such as rent ceilings and minimum wages.

Watch out

A price ceiling is only effective below the equilibrium price, and a price floor is only effective above the equilibrium price.

Tax theory and practice introduction

Direct vs Indirect TaxesReference tableImpact and Incidence · Tax Shifting · Examples

Feature	Direct Tax	Indirect Tax
Impact and Incidence	Fall on the same person	Fall on different persons
Tax Shifting	Cannot be shifted	Can be shifted to consumers
Examples	Employment tax, Business tax	VAT, Excise tax, Customs duty

When you use it

Use this comparison to distinguish who bears statutory responsibility versus the ultimate economic burden of a tax.

Watch out

Impact is the statutory first point of contact, while incidence is the final economic resting place.

Ethiopian Income Tax SchedulesReference tableSchedule A · Schedule B · Schedule C · +2

Schedule	Source of Income
Schedule A	Employment income
Schedule B	Rental income from buildings
Schedule C	Business income
Schedule D	Other income (royalties, dividends, casual rental)
Schedule E	Exempt income (medical, hardship, pension)

When you use it

Use this table when classifying sources of income and their legal categories according to Ethiopian tax proclamation.

Watch out

Schedule E represents exempt income categories, not a taxable rate band.

Taxes by Rate ProgressionReference tableProgressive · Proportional · Regressive

Tax Type	Average Tax Rate	Distribution of Burden
Progressive	Rises as income rises	High income pays a higher share
Proportional	Remains constant for all income	Everyone pays the same percentage
Regressive	Falls as income rises	High income pays a lower share

When you use it

Use this classification to evaluate tax fairness and vertical equity based on taxpayer income levels.

Watch out

A regressive tax takes a larger percentage from low-income earners, even if high-income earners pay a larger absolute amount.

Drafted from Grade 12 Economics, pages 103-122, then checked twice before it went up

Poverty and inequality

Absolute versus Relative Poverty ConfusionCommon mistake

When you use it

Use when distinguishing the conceptual boundaries between absolute deprivation and relative income inequality.

Watch out

Relative poverty measures income distribution relative to others and can exist even when basic subsistence needs are met, while absolute poverty is the inability to afford life-sustaining essentials.

Drafted from Grade 12 Economics, pages 123-148, then checked twice before it went up

Gini CoefficientFormula

G = \frac{A}{A + B}

G = \frac{A}{A + B}

$G$: Gini coefficient $dimensionless$
$A$: Area between the 45 degree line of perfect equality and the Lorenz curve $dimensionless$
$B$: Area under the Lorenz curve $dimensionless$

When you use it

Use to quantify the degree of income inequality in an economy using the Lorenz curve areas.

Watch out

A Gini coefficient of 0 means perfect equality, while a value of 1 represents complete inequality.

Headcount RatioFormula

HCR = \frac{H}{N}

HCR = \frac{H}{N}

$HCR$: Headcount ratio $dimensionless$
$H$: Headcount of people living below the poverty line $dimensionless$
$N$: Total population $dimensionless$

When you use it

Use this formula to calculate the proportion of a country's total population that falls below the absolute poverty line.

Watch out

Headcount ratio only measures the incidence of poverty, not the depth or severity of income shortfall among the poor.

Indigenous Mutual Support InstitutionsReference tableIdir · Iqub · Debo

Institution	Nature	Primary Function
Idir	Traditional burial and group insurance association	Financial and social assistance during bereavement and emergencies
Iqub	Rotating savings and credit association	Pooling regular savings to fund investments and major household expenses
Debo	Communal labour pooling group	Rotational free agricultural and manual labour sharing among members

When you use it

Use when identifying traditional Ethiopian socio-economic institutions that help alleviate poverty and provide mutual security.

Watch out

Idir is a long term insurance-oriented association, whereas Iqub focuses primarily on rotating credit and savings.

Multidimensional Poverty Index Dimensions and WeightsReference tableHealth · Education · Living Standard

Dimension	Indicator	Weight
Health	Child mortality in the family	$\frac{1}{6}$
Health	Malnutrition of adult or child	$\frac{1}{6}$
Education	No household member completed 5 years of schooling	$\frac{1}{6}$
Education	Any school-age child out of school (grades 1 to 8)	$\frac{1}{6}$
Living Standard	Deprivations in electricity, water, sanitation, floor, cooking fuel, assets	$\frac{1}{18} \text{ each} \; (\frac{1}{3} \text{ total})$

When you use it

Use when examining the three core dimensions and deprivations comprising the Multidimensional Poverty Index.

Watch out

Health and Education each account for one third total weight, divided equally into one sixth per indicator.

Macroeconomic Reforms in Ethiopia

Derg Four Economic Planning PhasesReference tablePhase I · Phase II · Phase III · +1

Phase	Period	Economic Characteristic
Phase I	1974 to 1978	Nationalization and economic dislocation
Phase II	1978 to 1980	Zemecha campaign and temporary GDP recovery
Phase III	1980 to 1985	Severe drought, input decline, and stagnation
Phase IV	1985 to 1990	Ten-Year Perspective Plan and state farms

When you use it

Use when reviewing the four distinct post-1974 socialist economic phases and their respective growth shocks.

Watch out

Phase II experienced temporary recovery due to the Zemecha campaign and good weather, not long-term structural industrialization.

Home-Grown Economic Reform Three PillarsRule

When you use it

Use when classifying the structural components of the Home-Grown Economic Reform (HGER) program.

Watch out

HGER transitions the growth model from debt-financed public investments to private sector-led growth across macroeconomic, sectoral, and structural pillars.

Imperial Five-Year Development PlansReference tableFirst Five-Year Plan · Second Five-Year Plan · Third Five-Year Plan

Plan	Period	Core Strategic Focus
First Five-Year Plan	1957 to 1961	Infrastructure, communications, and processing industries
Second Five-Year Plan	1962 to 1967	Agro-industry and large-scale commercial farming
Third Five-Year Plan	1968 to 1973	Peasant agriculture and addressing food shortages

When you use it

Use when identifying the evolution of centralized planning under the Imperial regime from 1957 to 1973.

Watch out

The Third Plan shifted focus toward peasant agriculture due to food shortages, whereas the First and Second prioritized processing and commercial agriculture.

Pre-2020 Growth Financing MisconceptionCommon mistake

When you use it

Use when analyzing macroeconomic imbalances and reasons behind the debt crisis during the GTP I and GTP II periods.

Watch out

Do not assume high GDP growth from 2010 to 2020 was driven by export expansion. It was driven by public infrastructure spending funded by external debt, which widened the trade deficit and fueled inflation.

Economy, Environment and Climate Change

Classes of Adaptation StrategiesReference tableMobility · Storage · Diversification · +1

Adaptation Strategy	Mechanism and Function
Mobility	Avoids risks across space
Storage	Reduces risks experienced over time
Diversification	Reduces risks across assets owned by households or collectives
Communal pool	Joint ownership, resource sharing, and collective mobilization during scarcity

When you use it

Use this table to distinguish between the four primary mechanisms households and communities use to adapt to climate risks.

Watch out

Storage manages risk across time, whereas mobility manages risk across geographic space.

Environmental Kuznets CurveRule

When you use it

Use this rule when analyzing the relationship between economic growth, per capita income, and environmental degradation.

Watch out

Environmental degradation does not decrease immediately as an economy grows. It first rises and then falls in an inverted-U pattern.

Drafted from Grade 12 Economics, page 183 onwards, then checked twice before it went up

Mitigation vs AdaptationCommon mistake

When you use it

Use this when classifying climate change policy responses as either tackling causes or dealing with consequences.

Watch out

Mitigation is a preventive policy addressing the causes by reducing emissions, whereas adaptation is a reactive policy adjusting to the consequences.
