Edexcel Economics (A) A-level - Theme 1.1 Nature of Economics

Comprehensive practice flashcards reviewing Edexcel Economics A-level Theme 1.1: Nature of Economics, covering economic models, statements, scarcity, opportunity cost, PPFs, specialisation, division of labour, functions of money, and economic systems.

What is the key structural difference between economic theories and economic models?

Economic theories are generally expressed in words, whereas economic models are expressed in mathematical terms to achieve greater precision.

What does the Latin term ceteris paribus mean in economics?

It means "all other things remaining equal." Economists use it to isolate the effect of a single variable by assuming all other variables remain unchanged.

Why is economics classified as a social science rather than a natural science?

Economics studies human behavior, making it difficult to set up controlled laboratory experiments because real-world variables are constantly changing.

How do positive economic statements differ from normative economic statements?

Positive statements are objective and can be tested, proven, or disproven using evidence. Normative statements are subjective, value-based opinions containing terms like "should" or "ought" that cannot be tested.

What is the fundamental economic problem facing all individuals and societies?

The problem of scarcity, which occurs because human wants are infinite, but the resources available to satisfy those wants are finite.

What three basic economic questions must every economy answer due to resource scarcity?

1. What to produce
2. How to produce it
3. For whom production should take place

What defines a renewable resource compared to a non-renewable resource?

A renewable resource can be replenished naturally at a rate equal to or greater than its rate of consumption. A non-renewable resource cannot be readily replaced by natural means at the rate it is consumed.

What is the definition of opportunity cost?

Opportunity cost is the cost of one choice expressed in terms of the next best alternative that is given up.

What does a Production Possibility Frontier (PPF) represent?

A PPF shows the maximum possible combinations of capital goods and consumer goods an economy can produce when using all its current resources and technology fully and efficiently.

Based on this diagram, what is the opportunity cost of increasing consumer goods production from $60$ to $75$ units (moving from point A to point B)?

The opportunity cost is $30$ capital goods (a decrease from $60$ to $30$ capital goods).

Based on this linear Production Possibility Frontier, what is the opportunity cost of producing $1$ unit of a consumer good?

The opportunity cost is $3$ capital goods, calculated as $\frac{600}{200} = 3$.

On a PPF diagram, what do parallel outward shifts and inward shifts represent?

An outward shift (purple arrows) represents economic growth due to an increase in the quantity or quality of resources. An inward shift (orange arrows) represents economic decline or reduced productive capacity.

In this PPF diagram, what do points A, B, and C represent?

Point A represents efficient production on the PPF curve. Point B represents attainable but inefficient production inside the curve. Point C represents unattainable production beyond the economy's current capacity.

What change in an economy's productive capability is illustrated by this PPF diagram?

A fall in the maximum potential output of capital goods with no change in the potential output of consumer goods, indicating reduced efficiency or lost resources specific to capital goods.

What causes the shift shown in this PPF diagram?

An improvement in technology or resource efficiency that specifically increases the maximum potential output of consumer goods without affecting capital goods production.

What is the difference between consumer goods and capital goods?

Consumer goods are goods demanded and bought directly by households and individuals for satisfaction. Capital goods are goods produced to aid in the future production of consumer goods.

What is specialisation, and how is it related to the division of labour?

Specialisation is the production of a limited range of goods by a worker, firm, or country. The division of labour is a specific form of specialisation where the production process is split into separate tasks assigned to individual workers.

How did Adam Smith demonstrate the benefits of the division of labour in his pin factory observation?

Adam Smith observed that dividing pin production into $18$ distinct operations allowed a factory to produce $5,000$ pins per worker daily, whereas an individual worker making whole pins alone could produce only a few dozen.

What are three major advantages of applying the division of labour in production?

1. Increased worker productivity and skill specialization
2. Time saved by not switching between tasks or tools
3. Lower training costs since workers only learn one specific operation

What are the four primary functions of money in an economy?

1. Medium of exchange
2. Measure of value
3. Store of value
4. Method for deferred payment

What is a major requirement for barter to occur that is eliminated by money?

A double coincidence of wants, where both parties in a transaction must desire the exact good that the other party is offering.

How are resources allocated in a free market economy, according to Adam Smith?

Resources are allocated automatically through the price mechanism driven by consumer sovereignty and firm profit motives; Adam Smith referred to this self-regulating system as the "invisible hand."

What was Friedrich Hayek's main critique of government-planned command economies?

Hayek argued that government central planning leads to a loss of individual freedom and forcing minority preferences on society, whereas individuals in free markets best understand their own specific situation and needs.

How are resources allocated in a command economy, and what were Karl Marx's views on capitalism?

Resources are directly owned and allocated by the state. Karl Marx argued that capitalism exploits labor by underpaying workers, predicting competition would cause capitalism to collapse and give way to communism.

What is a mixed economy, and what four key roles does the government play within it?

A mixed economy uses both price mechanism market forces and state planning to allocate resources. The government's roles are: 1. Creating a framework of rules (e.g., regulating monopolies with over 25\text{\textpercent} market share), 2. Supplementing/modifying prices (providing public/merit goods), 3. Redistributing income via taxes and benefits, 4. Stabilising the economy.
