1: Introduction to Microeconomics Flashcards
Explain the relationship between living standards and resources
Resources (natural, labour, capital etc.) are needed to produce the goods and services which enable enjoyment of high living standards.
As resources are scarce/limited, production levels and therefore material living standards are restricted.
What is economics?
Economics is the study of human behaviour which involves analysing the ways businesses, individuals, governments and families (B.I.G FAMILIES) make decisions/choices about how to use their limited resources to satisfy their basic needs and unlimited wants.
Identify 2 main branches of economics
Macroeconomics & Microeconomics
What is microeconomics?
A branch of economics which examines individual decision-making by firms and households, and how this impacts a particular market for a single good or service.
What is macroeconomics?
A branch of economics which looks at the whole economy and the factors that affect the nation’s general economic conditions.
What are needs?
Goods and services necessary for survival
What are wants?
Unessential goods and services that make life more enjoyable
What is a fundamental assumption about needs and wants in economics?
They are infinite/unlimited
Why are needs and wants unlimited?
- They arise from several sources e.g. household, business, government and overseas sector.
- Keep up with trends (materialism)
- As one satisfied, another appears
- More have, more want due to advertising
- Many needs and wants reoccur e.g. need for food
- Planned obsolescence
- Population growth
What are resources/factors of production?
Productive inputs used by firms to make or supply good and services
Identify the three main types of resources
- natural
- labour
- capital
What are natural resources?
Productive inputs that occur in nature
e.g. soil, oceans, rivers, snow, rainfall, forests etc.
What are labour resources?
The intellectual skills, knowledge and manual effort that people provide as members of the nation’s labour force
e.g. those of doctors, engineers, teachers etc.
What are capital resources?
Manufactured or produced goods that are used by a firm to help make other finished goods and services. They are seen as the stock of past production that is used to aid current and future production
e.g. highways, mills, tractors, machinery etc.
What is productive capacity?
The maximum possible output of an economy using its limited resources as efficiently as possible.
Represented as PPF
What is relative scarcity?
The basic economic problem where the resources available for production are limited and relative to society’s unlimited wants.
Describe some consequences of relative scarcity
Economic activity and growth is limited, and not all needs/wants can be satisfied. So, only the most important ones are actually satisfied.
Indicate the relationship between price and relative scarcity
Price of good/service linked to its relative scarcity.
$$$ diamonds are relatively scarcer than air which is not scarce at all and therefore free. A low priced item that is more scarce than air, but not as scarce as diamonds may be found in abundance.
What is resource allocation?
Involves making choices about how scarce productive inputs are to be used and distributed among competing areas of production
How does resource allocation lead to opportunity costs?
Relative scarcity means unlimited volume of goods and services cannot be produced. So, firms must decide how to use and distribute resources most efficiently, selecting certain areas of production in which most efficient production can be achieved. This gives rise to opportunity costs.
What is an opportunity cost?
The value of the next best alternative that was forgone when a choice was made.
What is a production possibility diagram?
A diagram used to illustrate the many production combinations of a country that is able to produce just two products and where all resources are used most efficiently. These combinations are illustrated as points on a production possibility frontier and illustrate the concept of opportunity cost.
Identify simplified assumptions made in PPDs
assumes only 2 types of output can be produced
assumes total quantity of resources available is fixed
assumes nation uses most efficient production methods
What is the production possibility frontier (PPF)?
A line which traces out the productive capacity or a nation’s potential output, given the efficient and complete use of all resources.
What is efficient allocation of resources formally known as?
Allocative efficiency
What is economic efficiency?
When there is maximum output gained from a given volume of productive inputs, thereby maximising society’s general wellbeing and material living standards. It can mean allocative, dynamic, productive and intertemporal efficiency
Define allocative efficiency
When resources are distributed in ways that maximise society’s satisfaction and minimise opportunity costs.
Define Productive or Technical Efficiency
When lowest cost production methods are used and wastage of resources in making goods and services is minimised.
Anywhere along the lines of the PPF curve is technically efficient; increase in technical efficiency would help shift PPF outwards.
Define dynamic efficiency
When resources are reallocated quickly to increase choice and better meet the changing needs of consumers. Shown on PPF as moving along curve quickly.
Define intertemporal efficiency
Refers to finding a balance between current consumption versus saving for future consumption. On PPF curve it can refer to anywhere not on the edges as either extremes are not balancing resources across long term
What things could increase the volume and efficiency of a nation’s resources and expand the PPF?
• rise in foreign investment
• increase in the target for skilled immigration
• discovery of new natural resources
• technological breakthroughs
• government spending on education and training of the labour force, or a rise in outlays on R&D
• rises in worker productivity or efficiency
• the building of new infrastructure such as roads, water and telecommunications
What can we say about the efficiency of a point INSIDE the PPF?
Can say that it’s is using resources inefficiently and would CERTAINLY lower society’s satisfaction and wellbeing.
What do points INSIDE the PPF indicate about employment?
At any point inside PPF, production levels are below maximum level and potential capacity. This implies that some resources are not being full used, and there is unemployment of workers and unused capacity in businesses.
What would we expect about living standards if point is inside the PPF?
Fall in income and living standards; potential rise in poverty
What does a point OUTSIDE the PPF signify?
It is currently beyond the economy’s productive capacity because there are insufficient resources to enable such high levels of output. Any attempt to operate at this level of national production would be likely to cause inflation by causing a general shortage in resources.
What is an economic system?
A way of organising the production and distribution of the nation’s goods, services and incomes.
What is a market capitalist economy?
An economic system in which resources are privately owned and decisions about what to produce, how to produce and for whom to produce are made by the market system
What is a market?
An institution where buyers and sellers of goods and services negotiate the price for each good or service.
How does the market price change when the number of buyers exceeds the number of sellers?
Market price rises
How does the market price change when the number of sellers exceeds the number of buyers?
Market price falls
What is market structure?
Refers to the type and level of competition that exists in various markets.
When do markets operate best?
When they are freely competitive
Identify the different market structures
- pure of perfect competition
- monopolistic competition
- oligopoly
- pure or perfect monopoly
What is pure of perfect competition?
A type of market structure in which there are many buyers and sellers of identical products, and competition is strong. Firms, having no market power, are price takers and have perfect knowledge about market conditions. There are no government barriers/restrictions so ease of entry exists.
What is monopolistic competition?
A type of market structure where there is a moderate number of buyers and sellers of similar, but not identical products. Competition is quite strong so firms are price takers, and product differentiation and advertising is important. Knowledge of market conditions is quite good and there is moderate ease of entry and exist as there are few government barriers/restrictions.
What is oligopoly?
A type of market structure where there are relatively few, large buyers who are price makers. Here, there is opportunity for collusion. Product differentiation is quite important, and entry/exit is fairly difficult due to many government barriers and restrictions.
What is a pure or perfect monopoly?
A type of market structure where one seller is a price maker and controls the output of an entire industry and there is no close substitute product. No competition exists and product differentiation is unimportant. Entry and exit are difficult due to government barriers and restrictions.
Identify the conditions of a perfectly competitive market
Consumer sovereignty
No market power
Ease of entry or exit
Identical products
Mobile resources
Profit maximisation
Perfect knowledge
What is consumer sovereignty?
When consumers of goods and services, not the government, dictate how resources will be used.
What is an acronym to help remember the conditions of a perfectly competitive market?
MInCE PPie!!!
Mobile Resources
Identical products
No market power
Consumer sovereignty
Ease of entry and exit
Perfect knowledge
Profit maximisation
What are the effects of competitive markets on efficiency in resource allocation?
- higher efficiency in resource allocation
- lower prices and higher purchasing power
- better quality goods and services
How does strong competition lead to higher efficiency?
With many rivals and no market power, firms must try to get more output from the same input and use their resources in ways that minimise opportunity costs, boosting allocative efficiency.
They must also innovate technology to survive, increasing productive/technical efficiency.
Firms need to be more responsive to changes in consumer demand to continue selling; increasing dynamic efficiency.
What effect can strong competition have on a nation’s productive capacity and living standards?
Strong competition = rivalling firms try to get more output from same inputs = increased inefficiency = PPF moves outwards and productive capacity increases
= higher GDP = higher employment = higher average income = improved material living standards.
How can strong competition lead to lower prices and greater purchasing power?
With more rivalry, firms will be forced to price their products competitively, and being price takers, will not collude or exploit consumers, leading to lower market prices, and increasing purchasing power.
How can strong competition lead to better quality goods and services?
Having many rivals, firms are forced to ensure that product quality is high so consumers are not motivated to buy from other sellers.
Outline some negative effects of strong competition?
- A struggling firm may employ aggressive cost-cutting and render low quality, unsafe products
- With many small-sized competitors, business would be less likely to gain e economies of large-scale production
Identify the three key economic questions
- What and how much to produce?
- How to produce?
- For whom to produce?
What are relative prices?
The price of one good or service compared to that of another.
How is the “what to produce” question addressed?
Product has higher equilibrium market price = relatively more profitable = produced more
Product has lower equilibrium = relatively less profitable = produced less
How is the “how to produce?” question addressed?
Cheaper + most efficient resources = minimise production costs and maximise output = preferred
How is the “for whom to produce?” question addressed?
People with higher incomes get more.
Incomes relative to relative scarcity of work provided.
Relatively scarcer work = higher relative income = higher purchasing power e.g. doctors
Relatively less scarce work = lower relative income = lower purchasing power e.g. teachers
