A country's budget allocation to various sectors of the economy is shown in the pie chart. If the budget of the country was $7,200.00, how much is allocated to Education?
A.$2,400.00.
B.$2,000.00
C.$1,200.00
D.$1,000.00
Show the answer and explanation
Answer: A ($2,400.00.)
Explanation
Education has 120° of 360°: 120/360 × 7,200 = $2,400.
People buy necessities even when prices rise, so demand is inelastic and the curve is steep. But they still buy slightly less at higher prices, so it slopes downwards (negatively sloped).
If the quantity of men's hat demanded per week is represented by the function Qd = 20 − (1/3)P, where P is price, how many hats are demanded when the price is $9.00?
When a number of countries agree to remove all trade barriers among themselves and at the same time charge a common tariff against non-member countries, it is known as
A.free trade area.
B.common market.
C.customs union.
D.economic community.
Show the answer and explanation
Answer: C (customs union.)
Explanation
Free trade among members plus a common external tariff is a customs union.
The following data shows the budget of a hypothetical country in 2006. Study the data and answer the questions that follow: Revenue | [$ millions] Company tax | 240 Workers' income tax | 160 Excise duties | 80 Taxes on exports | 100 Value added tax | 150 Import duties | 90 Non-tax revenue | 40 Expenditure | [$ millions] Construction of roads | 100 Building of schools | 120 Payment of workers' salaries | 150 Government administration | 200 Maintenance of health facilities | 220 Extension of electricity to rural areas | 180 Maintenance of official vehicles | 70 (a) Calculate the total (i) direct taxes; (ii) indirect taxes. (b) Calculate the total (i) recurrent expenditure; (ii) capital expenditure. (c) What percentage of total revenue was collected as indirect tax? (d) State two examples of non-tax revenue. (e) What was the budget surplus or deficit? Explain your answer.
Show the model answer
Model answer
(a)(i) Direct taxes = company tax 240 + workers' income tax 160 = $400 m (ii) Indirect taxes = excise 80 + export taxes 100 + VAT 150 + import duties 90 = $420 m (b)(i) Recurrent = salaries 150 + administration 200 + maintenance of health facilities 220 + maintenance of vehicles 70 = $640 m (ii) Capital = roads 100 + schools 120 + rural electricity 180 = $400 m (c) Total revenue = 400 + 420 + 40 = $860 m; indirect share = 420/860 × 100 ≈ 48.84% (d) Any two: rents and royalties; fees and fines; profits of public enterprises; grants and aid; sale of government property. (e) Total expenditure = 640 + 400 = $1,040 m; 1,040 − 860 = $180 m deficit, because expenditure is greater than revenue.
Explanation
Indirect taxes are on goods and trade; capital spending builds new assets.
The utility schedule of a consumer for a brand of ice cream is shown in the table below. Use the information to answer the questions that follow: Units Consumed (Q) | Total Utility (TU) | Marginal Utility (MU) 0 | 0 | – 1 | 10 | 10 2 | 19 | R 3 | P | 6 4 | 30 | 5 5 | 31 | S 6 | Q | 0 7 | 29 | −2 (a) Calculate the values of P, Q, R and S. (b) Given that the price of ice cream is $1.00 per unit, at what level of consumption is the consumer in equilibrium? Explain your answer. (c) Using a graph sheet, draw the marginal utility curve. (d) State the law of diminishing marginal utility.
Show the model answer
Model answer
(a) P = 19 + 6 = 25; Q = 31 + 0 = 31; R = 19 − 10 = 9; S = 31 − 30 = 1 (b) At 5 units, where MU (1) equals the price ($1.00, taking 1 util as worth $1): buying the 5th unit gives satisfaction just equal to what is paid; a 6th unit gives MU 0, less than the price. (c) Units on the horizontal axis, MU on the vertical axis; plot 10, 9, 6, 5, 1, 0, −2 for units 1–7 and join: a downward-sloping curve that cuts the horizontal axis at 6 units and goes below it at 7. (d) As a consumer takes more and more units of a commodity in a given period, the additional satisfaction from each extra unit eventually decreases.
Explanation
MU = change in TU; equilibrium for one good is where MU = price.
(a) What is a production possibility curve? (b) Draw a production possibility curve and indicate any: (i) point P, where resources are fully utilized; (ii) point U, where resources are under-utilized; (iii) point X, where production is not feasible. (c) Explain any two factors that can make production at point X feasible. (d) Why is the production possibility curve negatively sloped?
Show the model answer
Model answer
(a) A production possibility curve shows the different combinations of two goods that an economy can produce when all its resources are fully and efficiently used with given technology. (b) Concave curve between the two axes (each axis one good): P on the curve; U inside the curve; X outside the curve. (c) Any two: improvement in technology; discovery of new resources; increase in the quantity of labour or capital (investment, population growth); better education and skills; foreign aid/investment. These shift the curve outward so X becomes attainable. (d) Resources are scarce: to produce more of one good, some of the other must be given up (opportunity cost), so the curve slopes downward.
Explanation
Points on the curve: full use; inside: under-use; outside: unattainable now.
(a) What is: (i) peasant farming? (ii) co-operative farming? (b) Identify any five ways through which the government can assist peasant farmers.
Show the model answer
Model answer
(a)(i) Peasant farming: small-scale farming on small plots, using simple tools and family labour, mainly for family consumption with a little surplus for sale. (ii) Co-operative farming: farmers voluntarily pool land, labour, capital and equipment, farm and market together and share the benefits. (b) Any five: credit/loans at low interest; subsidised fertilisers, seeds and chemicals; extension services and training; provision of rural infrastructure (roads, storage, water); guaranteed minimum prices/marketing; land reform; mechanisation (tractor hire services); irrigation schemes; research into improved varieties; insurance against crop failure.
Explanation
Help should raise productivity or income of small farmers.
(a) What is price elasticity of supply? (b) Differentiate between joint supply and competitive supply. (c) Explain any four determinants of elasticity of supply.
Show the model answer
Model answer
(a) Price elasticity of supply is the degree of responsiveness of quantity supplied to a change in the commodity's price: % change in quantity supplied ÷ % change in price. (b) Joint supply: two goods produced together from one process, so more of one automatically gives more of the other (e.g. beef and hides, palm oil and kernel). Competitive supply: goods that compete for the same resources, so more of one means less of the other (e.g. cocoa and coffee on the same land). (c) Any four: time period; nature/perishability of the good; availability of spare capacity and stocks; mobility of factors; length of production period; cost of production; ease of entry of new firms; government policy.
Explanation
Joint: produced together; competitive: compete for resources.
(a) Define: (i) Building Society; (ii) Central Bank. (b) Highlight any five instruments of the Central Bank in regulating the supply of money.
Show the model answer
Model answer
(a)(i) A building society is a financial institution that accepts savings from members/the public and gives long-term loans (mortgages) for buying or building houses. (ii) A central bank is the apex financial institution of a country that issues currency, acts as banker to government and commercial banks, and controls money supply and credit. (b) Any five: open market operations; bank rate/monetary policy rate; cash reserve ratio; liquidity ratio; special deposits; selective credit control; moral suasion; credit ceilings; direct directives.
Explanation
Instruments change the banks' ability to create credit.
(a) Who is a discriminating monopolist? (b) Explain any four conditions necessary for a monopolist to practise price discrimination. (c) Explain any two benefits enjoyed by a discriminating monopolist.
Show the model answer
Model answer
(a) A discriminating monopolist is a sole seller who charges different prices to different buyers or markets for the same product for reasons not related to cost. (b) Any four: the seller must be a monopolist (no close substitutes); markets must be separable so buyers cannot resell (no seepage); different elasticities of demand in the markets; consumer ignorance or indifference; distance, tariffs or time separating markets; nature of the product (personal services such as medical care); legal sanction. (c) Any two: higher total revenue and profit; can sell to more buyers by charging low prices to the poor/elastic market; can use excess capacity; can dispose of surplus abroad (dumping); covers costs of services that would otherwise be unprofitable.
Explanation
Separate markets with different elasticities are essential.
Explain the following National Income concepts: (a) Gross Domestic Product (GDP); (b) Gross National Product (GNP); (c) Cost of living; (d) Per Capita income; (e) Standard of living.
Show the model answer
Model answer
(a) GDP: the total money value of all final goods and services produced within a country's borders in a year, by both citizens and foreigners. (b) GNP: the total money value of all final goods and services produced by a country's citizens and their firms at home and abroad in a year; GDP + net factor income from abroad. (c) Cost of living: the amount of money needed to buy the goods and services a person or family needs to maintain a given standard of living over a period. (d) Per capita income: national income divided by the population; average income per person. (e) Standard of living: the level of material well-being of people, measured by the quantity and quality of goods and services they enjoy (food, housing, health, education).
Explanation
GDP is about location; GNP is about ownership by citizens.
