Macroeconomics definitions Flashcards
Economic Growth:
measures the rate of change in a country’s output. An expansion in the productive potential capacity of an economy. Increase in Real GDP
Short run economic growth
the actual annual percentage change in real national output (real GDP)
Long run economic growth:
An expansion in the potential productive capacity of the economy
Gross Domestic Product
the value of the quantity of goods and services produced in the economy over a period of time
Real GDP:
the value of the quantity of goods and services produced in the economy over a period of time, adjusted for inflation (constant price)
Nominal GDP:
the value of the quantity of goods and services produced in the economy over a period of time, NOT adjusted for inflation (current price)
GDP per capita: the
the value of total GDP divided by the population of the country
Total GDP
the combined monetary value of all goods and services produced within a country’s borders during a specific time period
Total national income:
the value of all goods and services produced in an economy
Per capita income:
the total income divided by the population
GDP: Volume-
considers the quantity of goods produced within an economy, GDP adjusted for inflation
GDP: Value
considers the monetary worth of the goods and services produced within an economy, nominal figure.
Gross National Product (GNP):
Value of all goods and services produced over a period of time through the labour or property supplied by citizens of a country both domestically and overseas
Gross National Income:
GDP + net overseas interest payments and dividends (factor incomes)
Purchasing power parities (PPP):
an exchange rate of one currency for another which compares how much a typical basket of goods in one country costs compared to that of another country.
Happiness Economics:
looks at how content individuals are with their life from a theoretical and scientific viewpoint
Inflation
a sustained rise in the general price level within an economy in a given time period.
Inflation rate-
a sustained rise in the general price level within an economy in a given time period, expressed as a percentage
Deflation
a decrease in the GPL within an economy over a given time period
Disinflation
when the inflation rate is falling but it remains positive e.g. the rate of inflation falling from 4% to 2%
Consumer Price Index (CPI) –
measures household purchasing power with the Family Expenditure Survey by the ONS. The Survey finds out what consumers spend their income on. From this, a basket of goods is created (700 items). Goods are weighted according to how much income is spent on them.
Retail Price Index (RPI)
Alternative measure of inflation- unlike CPI, RPI includes housing costs (payments on mortgage interest and council tax)
Index numbers
useful way of expressing economic data time series and comparing/ contrasting information
Index number in Year Y= (Data value in Year Y/ Base Year Value) *100
Demand - pull inflation
a sustained rise in the GPL caused by excessive total (aggregate) demand in an economy for G&S
Cost push inflation
a sustained rise in the GPL caused by firms responding to rising costs of production by increasing prices of output
Money Supply
a measure of the amount of stock of money in the economy
MO: Narrow money
includes notes and coins in circulation
M4: Broad money
includes MO (notes and coins)
Shoe leather costs
due to distorted price signals, individuals shop around. The cost of looking around to find cheaper prices/ best rate of interest.
Fiscal drag
wages rise in line with inflation and an individual is dragged into a higher tax bracket therefore increasing government tax revenueenue without altering tax brackets
Menu costs
due to fluctuating prices, firms print new labels and therefore increases their costs
Unemployment-
those who are willing and able to work but aren’t employed. They’re actively seeking work and usually looking to start within the next two weeks.
Structural unemployment-
(supply side) occurs with a long time decline in demand for the goods and services in a particular industry leading to job losses.
Frictional unemployment (supply side
transitional unemployment that occurs as workers move between jobs, mainly through career changes or geographical change
Cyclical (demand- deficient) unemployment
caused by a lack of demand for goods and services- usually occurs during periods of economic decline or recessions (when there is negative output gap)
Seasonal unemployment
occurs when workers are unemployed at different times of the year
Real Wage Flexibility
(voluntary unemployment, classical unemployment) occurs when real wage rates are above the equilibrium wage rate causing the supply of labour to be greater than the demand of labour
The Claimant Count
measures the number of people claiming unemployment related benefits from the government, job seekers allowance, universal credit and small groups of additional claimants
The labour Force Survey-
It uses a sample of the population (44,000). It asks people who aren’t working if they’re actively seeking work. The number of people who answer yes are added up to produce the ILO unemployment count
Underemployment
occurs when workers cannot find a job that is suitable for their qualification and experience or who cannot find enough hours to work
Economically Inactive
people who are of working age who are not seeking work for whatever reason e.g. wealth, disability, discouragement
Full Employment-
when the number of job vacancies equals the number of people actively seeking work
Unemployment level
the number of people who are unemployed
Unemployment rate-
the number of people who are unemployed expressed as a % of the labour force
Formula for unemployment
unemployed workers/ total labour force * 100
Economically inactive people aren’t included in total labour force
Hidden Unemployment
people who are not in work and not seeking work. If they were offered a job they’d take it.
Long term unemployment
when someone is unemployed for more than one year
Net Migration
the difference between emigration (those leaving the UK) and immigration (those entering the UK)
Balance of Payments
A record of a country’s transactions with the rest of the world
Exports
Goods and services sold to foreign countries- positive on the balance of payments as they are an INFLOW of money. Added to Real GDP
Imports
Goods and services bought from foreign countries- negative on the BOP as they are an OUTFLOW of money. Subtracted from Real GDP
Current account:
consists of trade in goods, trade in services, investment income, current transfers
Current account surplus:
When the sum of exports, goods, services, investment income and transfers is greater than imports
Current account deficit:
When the sum of exports, goods, services, investment income and transfers is less than imports
Financial account
consists of FDI, portfolio investment, gold reserves, hot money flows
Investment income:
The reward for investments in other countries. Comprises of interest, profit and dividends
Aggregate demand-
the total level of planned real expenditure on goods and services procedures within a country in a given time period
Consumption
how much consumers spend on goods and services. Consumer income may come from wages, savings, pension, benefit, and investments such a dividend payments
Disposable income
the amount of income consumers has left over after taxes and social security charges have been removed, i.e. what consumer can choose to spend
The savings ratio
gives an idea of the average extent of saving for all households in an economy. It is calculated as the % of disposable income that is saved
The Pigou effect
occurs when consumers increase consumption due to an increase in the value of assets such as house prices, shares etc. This would lead to higher output and increased employment
Marginal propensity to consume-
refers to how likely an individual is to consume an extra £1 of income they receive. A proportion of a change in income (margin) that will be spent on consumption rather than being saved.
Marginal propensity to save (MPS
refers to the proportion of any extra income that is saved by consumers
Marginal propensity to withdraw (MPW)
a measure of how much of any extra pound earned is saved, taxed or spent outside the economy on imports
Investment
expenditure undertaken by firms to add to the capital stock in the economy
Gross investment-
the total amount the economy spends on new capital. Spending on capital assets such as buildings, machinery and equipment= increases the productive capacity of the economy leading to economic growth.
Net investment
net investment = gross investment – capital depreciation. If gross investment is higher than depreciation, then net investment will be positive. Thus meaning businesses will have a higher productive capacity and can meet rising demand in the future.
Animal Spirits
John Maynard Keynes coined this term to refer to the collective mood of investors. When this is strong AD increases leading to greater capital investment
The accelerator effect-
this happens when an increase in national income (GDP) results in a proportionately larger rise in capital investment spending. Often see a surge in capital spending by businesses when an economy is growing quite strongly.
Net exports
the export of goods and products means that money flows into the country; when the value of the money flowing out the country as imports is deducted, a figure for the net export is the result
Marginal propensity to import
the amount of additional income that households spend on imports
Exchange rates:
the price of one currency expressed in terms of another currency
Government Spending
tax revenue and borrowing spent by the government for the benefit of the country’s citizens
Transfer payments
a redistribution of income and wealth made without goods or services being received in return
Automatic stabilisers
effects which help influence the path of economic growth due to cyclical changes in tax revenue and welfare costs
Fiscal policy-
government changes to spending, taxation and borrowing to manipulate the economy
The multiplier effect
when an initial injection into the economy has a bigger final impact on real GDP. An increase in investment or other injection will lead to an even greater increase in national income.
Current expenditure
government spending on the day to day running of the country e.g. wages. An increase will see a shift in the SRAS curve to the right
Capital expenditure
government spending on physical assets will help to develop infrastructure, allowing businesses to operate effectively and efficiently. This will help shift the LRAS curve to the right and PPF outwards
Balanced budget
this occurs when government expenditure is equal to government revenue through taxations
Budget deficit
where government expenditure exceeds tax rev
Budget surplus
where taxation exceeds government expenditure
Aggregate supply
is the volume of goods and services produced within the economy at a given price level. It indicates the ability of an economy to produce goods and services and shows the relationship between the real GDP and the average price levels.
Short run AS
changes in the value of output in the short run caused by changes in the cost or production
Classical economists LRAS
the classical view of LRAS suggest that the economy will always produce the maximum that its factor resources will allow
Keynesian economists LRAS
an economy could be in equilibrium below full employment
Keynesian LRAS
The Keynesian AS curve is shaped due to the level of spare capacity available in the economy indicating that the economy can be in the long run at any level of output (Real GDP) due to the inflexibility of wages downwards. When there’s large level of spare capacity Keynesian believe that the output can increase without putting excess pressure on existing factors of production given the large amount of unemployed resources in the economy. Therefore Real GDP can increase without any demand pull inflationary pressure hence why the curve is horizontal at low levels of Real GDP.
Only when the economy approaches full capacity, Yfe, that for Real GDP to increase, pressure is put on existing factors of production increasing the price of them and thus costs of production for businesses- resulting In higher prices filtering out through the economy, increasing the inflation rate.
There comes a point when no spare capacity exists and thus Real GDP cannot increase without large increases in inflationary pressure, unsustainable production.
Circular flow of income
an economic model showing the flow of goods and services, the factors of production and their payments between households and firms within an economy
The wealth effect-
the effect on incomes or spending when asset value changes
Injections-
flows into the circular flow of income i.e. investment, government spending, and imports
Withdrawals
flows out of the circular flow of income i.e. savings, taxes, and imports
The multiplier effect
occurs when an initial injection into the economy, or circular flow of income causes a proportionately larger final increase in the level of real national income/ output, facilitating further rounds of spending and income generation.
K= 1/MPW
K= 1/ (1-MPC) - where MPW=MPS+MPT+MPM
Keynesian multiplier theory
the more the government spends, the more an economy will flourish
Marginal propensity to consume
the proportion of a change in income (the margin) that will be spent on consumption rather than being saved
Marginal propensity to withdraw-
measure of how much of any extra pound is saved, taxed or spent outside the economy
Income
a flow concept
Wealth
a stock concept
Economic growth
measures the rate of change in a country’s output. An expansion of the productive potential of an economy. Increase in Real GDP
Short run economic growth-
measures the rate of change in a country’s output. An expansion of the productive potential of an economy. Increase in Real GDP
Short run economic growth-
the actual annual percentage change in real national output (Real GDP)
Long run economic growth
an expansion in the potential productive capacity of the economy
Actual economic growth-
short run growth caused by increased real GDP
Potential economic growth
long run growth caused by increased productive potential
Migration
the movement of people from one country to another
Export led growth
economic growth caused by rises in net exports
Output gap
the output gap is the difference between the trend rate and actual rate of economic growth
Trend rate
the trend rate of economic growth is the average rate of growth of GDP is over time. It shows the potential output of an economy
Potential output
potential output occurs when the economy is working at full capacity over the long term. This occurs when all factors of production are working efficiently
Positive output gap
occurs when the actual rate of economic growth is above the long run trend rate. This happens during periods of high economic growth and is associated with inflationary pressure and low unemployment
Negative output gap-
occurs when the actual trend rate of economic growth is below the long run trend rate. This happens during periods of low or negative economic growth and is associated with deflationary pressure and high unemployment
Trade cycle
variations in the level of productive capacity of an economy over time
Productive capacity/ productive potential-
the maximum amount of goods and services that we can produce with the resources we have available
GDP
the value of goods and services produced in the economy over a period of time
Boom
a period of high levels of economic activity
Recession
the rate of economic growth starts to fall in a downturn. Two consecutive quarters of negative real GDP
Slump
the bottom of the business cycle which represents a period of serious economic decline. Low or negative economic growth.
Recovery
when there are often signs that economic growth is starting to rise often referred to as the green shoots of recovery
Demand side policies
a deliberate manipulation by the government of aggregate demand in order to achieve macroeconomic objectives
Monetary policy
involves the monetary instruments such as interest rates and the money supply (quantitative easing) to influence one or more of the components of aggregate demand
Contractionary monetary policy-
reduces the size of the money supply or raises the interest rate in order to reduce AD
Expansionary monetary policy-
increases the size of the money supply, decreases the interest rate in order to increase AD
Interest rate
the cost of borrowing, reward for saving, return for lending
Base rate
set by the BOE. The rate at which the BOE will lend to the financial system and Influences the structure of all other interest rates
