THEME 1, Nature of Economics (1.1) Flashcards
1
Q
What is Ceteris Paribus?
A
All things being equal: The assumption that, whilst the effects of a change in one variable are being investigated, all other changes have been kept constant
2
Q
What is an economic law?
A
A theory or model which has been verified by empirical evidence
3
Q
What is Normative Economics?
A
The study and presentation of policy prescriptions involving value judgements about the way in which scarce resources are allocated.
4
Q
What is Positive Economics?
A
The scientific or objective study of the allocation of resources.
5
Q
What is a Positive Statement?
A
A statement which can be supported or refuted by evidence.
6
Q
What is a Normative Statement?
A
A statement which cannot be refuted or supported by evidence. This is also a value judgement.
7
Q
What is the Scientific method?
A
A method which subjects hypotheses to falsification by empirical evidence.
8
Q
What is a theory/model?
A
A hypothesis which is capable of refutation by empirical evidence
9
Q
What do assumptions allow for?
A
They allow us to simplify a problem so we can solve it.
10
Q
What does the word ‘rational’ mean?
A
It means that economic agents have well defined preferences.
They act to maximise their self interest.
11
Q
What does evaluating mean?
A
Thinking how valid our analysis has been.
12

A
The workforce
16
Q
What is ‘capital’?
A
Money spent on goods used to manufacture goods and services.
17
Q
What is ‘enterprise’?
A
Seeking out profitable opportunities for production and take risks in attempting to exploit these.
18
Q
What are economic goods?
A
Goods that are scarce because their use has an opportunity cost.
19
Q
What is the fundamental economic problem?
A
Resources have to be allocated between competing uses because wants are infinite whilst resources are finite/scarce.
20
Q
What is ‘fixed capital’?
A
Economic resources such as factories and hospitals which are used to transform working capital into goods and services.
21
Q
What are free goods?
A

Forests
Water
26
What is a sustainable resource?
Sustainable resources can be exploited economically and will not diminish or run out.
E.g. a forest is renewable however it is only sustainable if it survives over time despite logging or commercial farming.
27
What is an economy?
An economy is a system which attempts to resolve the basic economic problem.
28
How to economists distinguish three parts to the economic problem?
* What is to be produced? (Output/input spending)
* How is production to be organised? (E.g where should smartphones be made?)
* For whom is production going to take place? (What proportion of output should go to the workforce?)
29
Why do some people have more than others?
* Background
* Inheritance
* Oppurtunity
* Luck
* Location (1st world, 2nd world...)
30
What is market mechanism?
A system of the market where the forces of demand and supply determine the price and quantity of goods and services traded.
31
What is VAT?
* Value added tax
* A tax on spending/consumption
32
What is allocative efficiency?
* Producing the things that people want the most
* Only one point on the PPF graph is allocatively efficient
33
What is productive efficiency?
* Producing the maximum outputs from the given inputs
* All points on the curve are points of maximum productive efficiency
34
What is it called when a point is inside the curve on a PPF graph?
Unemployed resource
35
How are axis labelled on a microeconomics diagram?
* Good A / Good B
* Capital / Consumption
36
What moves the PPF out?
* Increase in factors of production (e.g. inward immigration (more labour), more investment in Capital))
* Increase in the quality of the factors of production (productivity)
* The efficiency with which factors of production can be combined
37
What is SR growth?
* Short run growth
38
What is LR growth?
* Long run growth
39
What is static efficiency?
* Productive and allocative efficiency
40
What would happen to the curve if the firms became more efficient at producing Good B but there was no change to Good A? Why might this situation arise?
* PPF would be pushed out (towards the right)
* This situation might arise if technological advances for GOOB B but not GOOD A
* E.g. Yamaha making pianos and motor cycles
41
What are the implications of having unemployed resources?
* It is a waste of scarce resources
42
What is a real value?
* Data expressed in constant prices
* eg taking one time period as the base year and valuing quantities in other years at base year prices.
* It removes the impact of inflation
43
What is CPI?
Consumer Price Index
44
What is the Consumer Price Index?
A weighted price index used to measure inflation
45
What is the Claimant Count?
* A measure of unemployment, in which the number of people claiming Job Seeker's Allowance (JSA) is counted.
46
How is the Claimant Count calculated?
* Calculated using data from benefit offices to produce a partial indication of unemployment.
47
Why isn't the Claimant Count used internationality?
* Different countries receive different level of benefits.
48
What is a nominal value?
* Data expressed in the prices of the day
49
What is the labour force survey?
* Internationally comparable method used to measure employment and unemployment
50
What is survey data?
* Data produced from a sample of respondents
51
What are experimental statistics?
* Official statistics that are still in the testing stage and therefore subject to more uncertainty eg data on collaborative platforms
52
What are index numbers/ values?
* Where a series of data has been re-based relative to a base period which is given the value 100.
53
What is a base period / year?
* The period given the value 100 against which other values are compared when constructing a series of index numbers
54
What is the Log Scale?
* A scale which compresses the values on the vertical axis as they increase
55
What did Smith say about specialisation?
* Smith essentially said that by dividing the production of pins into 18 different tasks the output of pins could increase significantly.
* Each worker specialises and output
increases.
56
What is the definition of specialisation?
* When a firm, individual or country specialises in a single task or narrow range of skills
* E.g. Bangladesh specialises in the textile industry
57
What is needed to make specialisation effective?
* **Money**
* Without money trade would depend on barter and a double coincidence of wants
58
What impact does specialisation have on economic agents?
* Creates new jobs
* If other industries (E.g. coal stopped) then there is possible unemployment
59
What is gained from specialisation?
* Learning by doing
* Time saved switching between tasks
* Specialist equipment can be used.
* There are more opportunities for economies of scale, so the size of the
market increases.
* There is more competition and this gives an incentive for firms to lower their prices and costs
* Higher output and potentially higher quality, since production focusses on
what people are best at.
* There could be a greater variety of goods and services produced.
60
What are the downsides of specialisation?
* Vulnerability to economic shocks and technological change
* If workers are bored the quality of the product can decrease - lower productivity
* Overly specialist skills do not have flexibility and are not transferable to others jobs
* Variety could decrease for consumers.
* There could be higher worker turnover for firms, which means employees
become dissatisfied with their jobs and leave regularly
61
What does it mean to barter?
* To exchange one good or service for another
* It is a very inefficient mean of exchange
62
What did Adam Smith believe in?
* Believed in the free market economy and the laissez-faire approach by governments
63
Where did Adam Smith notice that specialisation could help the economy?
* In a Pin Factory
64
What did Smith say about specialisation?
* Smith essentially said that by dividing the production of pins into 18 different tasks the output of pins could increase significantly.
* Each worker specialises and output
increases.
