Basic Economic Concepts

An economy operating on its Production Possibility Curve produces two goods: Rice (in tonnes) and Tractors (in units). Currently, it produces $40$ tractors and $100$ tonnes of rice. When resources are reallocated to increase tractor production to $50$ units, rice production falls to $70$ tonnes. What is the opportunity cost of producing one additional tractor, expressed in tonnes of rice?

An economy's production possibility frontier for agricultural produce ($A$) and manufactured capital ($M$) is represented by the non-linear equation $A^2 + 4M^2 = 400$, where both $A$ and $M$ are measured in thousands of units. If the economy is currently operating efficiently by producing 12 thousand units of agricultural produce, what is the opportunity cost (in thousands of units) of manufactured capital sacrificed if agricultural output is increased to 16 thousand units?

An economy is currently operating at point $A$ on its Production Possibility Curve, producing $120$ units of consumer goods and $50$ units of capital goods. To meet a new production target, the economy shifts resources to point $B$, increasing the production of capital goods to $80$ units, while consumer goods production drops to $90$ units. What is the opportunity cost of producing the additional capital goods, expressed in units of consumer goods?

Tunde has $₦50,000$ saved and must choose between buying a laptop needed for an online coding course and buying a smartphone for personal entertainment. If Tunde decides to purchase the laptop, what is the opportunity cost of his decision?

A developing economy characterized by a high rate of unemployment and scarce foreign currency reserves must decide whether to construct its major highway network using manual labor with simple tools or imported heavy machinery. Which basic economic problem of society is this nation attempting to solve, and what is the primary economic factor determining its choice?

In a free market economic system, the fundamental economic decision of 'for whom to produce' is resolved primarily by the distribution of purchasing power and effective demand among consumers, rather than by individual need or administrative rationing.

A developing country produces only two commodities: Cocoa and Steel. If a technical innovation occurs that significantly improves agricultural yields for Cocoa without affecting Steel production efficiency, which of the following best describes the structural change in the nation's Production Possibility Curve (PPC)?

In an agricultural economy experiencing severe youth unemployment alongside rising food costs, commercial farming enterprise managers switch from labor-intensive methods to capital-intensive automated harvesting technologies to reduce unit operating expenses. Concurrently, the central authority imposes a mandatory price ceiling below the market equilibrium on harvested grain to protect low-income households. Under these combined conditions, how do the market-driven resolution of 'How to produce' and the state-imposed constraint on 'For whom to produce' interact to affect overall economic resource allocation?

An entrepreneur in Port Harcourt has sufficient capital to establish either a palm oil refinery or a commercial fish farm. If he chooses to invest in the palm oil refinery, what is the opportunity cost of his decision?

Match each economic system listed on the left with its defining structural feature on the right.

A manufacturing firm in Ibadan operates along its Production Possibility Curve (PPC) producing two goods: garments and shoes. Currently, when producing $150$ pairs of shoes, the firm can produce $400$ units of garments. To meet increased market demand for footwear, the firm reallocates its resources to produce $250$ pairs of shoes, causing garment output to fall to $150$ units.

Calculate the opportunity cost of producing one additional pair of shoes in terms of garments foregone.

In an economy undergoing structural reform, the government privatizes consumer goods manufacturing and allows prices to float based on market forces, but maintains absolute state monopoly and price controls over upstream raw materials and heavy infrastructure. Which of the following best analyzes the primary operational outcome of this resource allocation framework?

An economic researcher recorded the price per bag of cocoa (in thousands of Naira) across five key agricultural markets as $₦14$, $₦18$, $₦20$, $₦22$, and $₦26$. What is the coefficient of variation of these cocoa prices?

Match each economic system listed on the left with its corresponding major structural defect or operational limitation on the right.

A commercial farmer in Jos allocates all available agricultural resources to cultivate either Irish potatoes or maize. Using all resources for potatoes yields $100\text{ tonnes}$ of potatoes, while using all resources for maize yields $150\text{ tonnes}$ of maize. Assuming a constant rate of substitution along the production boundary, what is the opportunity cost of producing $1\text{ tonne}$ of potatoes in terms of tonnes of maize?

In economic analysis, nations resolve the fundamental questions of what, how, and for whom to produce through distinct institutional arrangements. Match each type of economic system on the left with its primary mechanism for directing resource allocation on the right.

A cooperative farm produced a total grain harvest of $1,200\text{ bags}$ in a farming season, consisting of $450\text{ bags}$ of maize, $350\text{ bags}$ of sorghum, and $400\text{ bags}$ of rice. What is the sectorial angle representing sorghum when this data is represented on a pie chart?

A bakery in Benin City allocates its daily supply of flour to produce either 100 loaves of bread or 50 meat pies. Currently, the bakery produces 20 meat pies. If the baker decides to increase meat pie production to 35 meat pies, what is the opportunity cost of this decision in terms of loaves of bread foregone?

A nation's total federal budget of $₦500\text{ billion}$ is allocated across four key sectors: Health ($₦125\text{ billion}$), Education ($₦175\text{ billion}$), Defense ($₦120\text{ billion}$), and Agriculture (the remainder). In a pie chart constructed to represent this budget distribution, what is the central angle (in degrees) representing the allocation for Agriculture?

The table below presents the distribution of daily expenditure on diesel (in $₦\text{'000}$) by $40$ micro-enterprises in a commercial hub:

What is the median daily expenditure on diesel for these enterprises?
