1
actual economic growth
increase in real gross domestic product
2
gross domestic product (GDP)
the total amount of goods and services produced in a country in one year
3
real
adjusted for inflation
4
potential economic growth
increase in the productive potential of an economy
5
recession
when an economy has two consecutive quarters of negative economic growth
6
GDP per capita
total GDP divided by the population
7
volume of output
amount of goods produced
8
value of output
amount of goods produced multiplied by the price at which they are sold
9
gross national income (GNI)
income received by a country both domestically (GDP) and via net incomes from overseas
10
GNI =
GDP + profits from companies operating abroad and income earned from nationals living in foreign countries - profits from foreign-owned companies and income earned from foreign nationals living in the country that goes abroad
11
purchasing power parities (PPPs)
used to compare GDP in different countries and takes into account the cost of a ‘basket of goods’ that could be bought in each of the countries being compared
12
PPP exchange rate
the rate that equalises the purchasing power of different currencies by eliminating differences in prices between countries
13
quality of life
a measure of living standards that takes into account housing, health, environment and safety
14
6 limitations of using GDP to compare living standards between countries
population, rates of inflation, income distribution, exhange rates, amount of self-consumed output, type of government spending
15
5 limitations of using GDP to compare living standards over time
population, rates of inflation, income distribution, amount of self-consumed output, type of government spending
16
subjective happiness
measure of how people feel about themselves
17
relationship between real incomes and subjective happiness
positive relationship up to a certain level of income, once income increases beyonf that level, marginal gains in happiness fall (Easterlin paradox)
18
policy implication of the Easterlin paradox
governments need to focus not only on economic growth but also on other objectives such as income equality and a clean environment
19
inflation
sustained rise in the general price level
20
deflation
sustained fall in the general price level
21
disinflation
fall in the rate of inflation
22
3 measures of inflation
consumper price index (CPI), CPIH, retail price index (RPI)
23
consumer price index (CPI)
weighted average of items on which people spend their money
24
measure of rate of inflation used to make international comparisons
CPI
25
real GDP =
nominal GDP / CPI
26
index number
number shown relative to another number in percentage terms
27
base year
used to compare price levels in different time periods
28
weight
proprtion of income spent on items
29
how the CPI is calculated
living costs and food survey collects information about purchases from 7000 households in the UK, data about the change in the prices of the 700 most commonly used goods and sercives is collected, weights are assigned to each item the average household buys, price changes are multiplied by weights to give a price index
30
CPI does not include
housing costs such as rent payments, mortgage interest repayments and council tax
31
5 limitations of CPI as a measure of the rate of inflation
does not inlude housing costs, unrepresentative spending patterns, does not account for changes in quality, sudden changes in spending patterns are not reflected, survey sampling issues
32
CPIH =
CPI + housing costs
33
preferred measure of inflation in the UK
CPIH
34
3 causes of inflation
demand-pull inflation, cost-push inflation, growth of money supply
35
demand-pull inflation occurs when
aggregate demand in the economy increases at a faster rate than aggregate supply
36
cost-push inflation occurs when
aggregate supply decreases as the cost of production increases
37
5 causes of demand pull-inflation
decrease in interest rates, rise in the level of business and consumer confidence, increase in government spending, exports rise relative to imports, depreciation of the exchange rate
38
5 causes of cost-push inflation
rise in raw material prices, depreciation of the exchagne rate, rise in taxes on businesses, increase in minimum wage, increased regulations
39
3 effects of inflation on consumers
income falls in real terms, real value of savings deceases, real value of loans fall
40
3 effects of inflation on firms
decrease in international competitiveness resulting in the worsening of the trade balance, uncertainty leading to a fall in investment, lower profits leading to afall in investment
41
3 effects of inflation on the government
fall in the real value of national debt, increased inequality, deteriration in the balance of trade
42
2 effects of inflation on workers
incomes of workers in a weak bargaining position may fall, unemployment
43
2 measures of employment
level of employment, rate of employment
44
level of employment
number of people in work
45
employment rate
number of people in work as a percentage of the working age population
46
2 measures of unemployment
claimant count, ILO (labour force survey)
47
claimant count
number of people caliming unemployment benefits, either from Jobseeker’s Allowance (JSA) or Universal Credit (UC)
48
Jobseeker’s Allowance (JSA) is paid to
people who are willing and able to work but are not currently in employment
49
3 advantages of claimant count as a measure of unemployment
reliable as it is based on real data, provide data about the potentail cost of unemployment to tax payers, available monthly
50
3 disadvantages of claimant count as a measure of unemploymnet
many people can’t claim it as they have savings or a partner in work, people claim dishonestly, not internationally comparable
51
3 advantages of the ILO as a measure of unemployment
statistically robust, internationally comparable, independent of benefits system
52
3 disadvantages of ILO as a measure of unemployment
costly to administer, only available quarterly, respondents may not asnwer honestly
53
unemployment rate
the number of unemployed people as a percentage of the labour force
54
labour force
people aged 16 and over who are either employed or unemployed
55
unemployed
people over the age of 16 who are not working, but who are available to work, and have either looked for job during last four weeks or are waiting to start a job in the next two weeks
56
employed3
people who have worked at least one hour paid work in the last four weeks or who are on government subsidized work experience or occupational training
57
underemployed
people who are employed but for fewer hours than they would like
58
economically inactive
poeple not in education, employment or training and who are not actively seeking work withint the last 4 weeks and are unavailable for work within the next 2 weeks
59
5 advantages of an increase in the employment rate
increased GDP, increased revenues and profits for firms, increased incomes leading to a higher standard of living, improved skills (human capital) of workers, higher government taxation revenue
60
human capital
the knowledge and skills of a workforce that determine its productivity
61
2 advantages of a decrease in the unemployment rates
falling government spending on JSA and UC, increased employment
62
3 effects of an increase in the inactivity rate
productive capacity of the country will fall, more claims on state benefits, dependency ration will increase (number of inactive people who are directly or indirectly supported by employed or active people)
63
5 types of unemployment
cyclical and demand deficient, structural, frictional, seasonal, real wage inflexibility (classical)
64
cyclical and demand deficient unemployment
caused by a fall in AD due to recession
65
structural unemployment
caused by a mismatch between the jobs available and the skills of workers
66
frictional unemployment
caused by people leaving a job and not yet starting another
67
seasonal unemployment
caused by a change in seasons
68
real wage inflexibility (classical) unemployment
caused by wages being above the equilibrium

70
8 reasons for migration
employment, to earn a higher income, better standard of living, to study abroad, to join other family members, to escape conflic or discrimination, to avoid high tax liabilities, remittances
71
4 impacts of a highly skilled workforce
increased productivity leading to an increase in economic growth, higher earnings, more stable and secure emplyments, lower income inequality and poverty
72
4 effects of unemployment on consumers
deacrease in living standards, loss of confidence leading to lower consumer spending, mental illness, lower house prices and fall in personal wealth
73
3 effects of unemployment on firms
easier to recruit new employees, less consumer spending so fall in sales and profits, lower costs of production due to low wages
74
4 effects of unemployment on workers
loss of skills, loss of income, lower living standards, long-term unemployment means it is more difficult to get a job in the future
75
4 effects of unemployment on government and society
increasing spending on government debts, less revenue from income and indirect taxes, opportunity cost (the goods and services that could have been produced by the unemployed workers), rise in inequality, crime and polutical unrest
76
balance of payments
record of international payments over the course of a year
77
current account =
balance of trade + primary balance + secondary balance
78
balance of trade =
