2.1 - Measures of Economic Performance Flashcards
What is macroeconomics?
Macroeconomics is a part of economics focusing on behavior of collective businesses and consumers, as well as the impact of the government on these collective businesses and consumers.
List the four macro-economical objectives.
- Inflation
- Economic growth
- Unemployment
- Balance of payments
Give some alternative macro economical objectives.
- Greater equality (regional/wealth/income)
- Increased access to public services
- Environmental sustainability
- Improved economic well-being (social welfare/mobility)
What is economic growth in the short run?
In the short run, economic growth is the actual annual percentage change for real national output.
How do you measure economic growth in the short run?
In the short-run, economic growth is measured by the percentage change in real GDP (gross domestic product) per year.
What is economic growth in the long run?
In the long run, economic growth is the increase in the potential productive capacity of an economy.
How is economic growth in the long run measured?
In the long run, economic growth is measured through the shift in the PPF graph (production possibility frontier - illustrates maximum potential output of capital and consumer goods, taking into account scarce resources).
Define GDP.
Gross Domestic Product, or GDP, is the total market value of all goods and services produced within a country within a year.
Give two ways to calculate the GDP.
GDP can be calculated either by adding total income (wages, interest, profits) within a year or total expenditure (consumption, investment, net exports) within a year; this means that the national output = national income = national expenditure.
What is national expenditure?
National expenditure is the total government spending in an economy.
What is nominal GDP?
Nominal GDP is the GDP expressed in monetary terms, not taking into account the inflation.
What is real GDP?
Real GDP is GDP which includes market value of production of goods and services as well as inflation.
What does nominal GDP measure?
Nominal GDP measures national output at current prices but it doesn’t include effects of inflation.
What does real GDP measure?
Real GDP measures output at constant prices and it also includes the effects of inflation, which is why economists refer to real GDP when discussing economic growth. This is because inflation can decrease a GDP, so the nominal GDP may show the GDP higher than it really is.
Give the formula for real GDP.
Real GDP = Nominal GDP / Average price level
What is a ‘boom’ in an economy?
If there are long periods of economic growth, then these are referred to as ‘booms’.
What is an economic recession?
If, for at least two consecutive quarters (each quarter lasting 3 months), negative economic growth occurs then this is referred to as a recession. Long periods of economic downturn can result in an ‘economic depression’.
What is the total real GDP?
The total (real) GDP is the value of goods and services produced within a country in a given year. This can be used my economists to deduce the size of the economy and compare with other countries.
Define GDP per capita?
GDP per capita is the total GDP divided by the population of the country, allowing economists to see standards of life for citizens.
Give the two indicators of GDP per capita.
- GNI (Gross National Income)
- GNP (Gross National Product)
Define GNI.
Gross National Income is the GDP per capita + net income abroad. Net income from abroad include income earned from international investments and owned assets abroad, but not from domestic investments by foreigners.
GNI per capita = (Total GNI) / Population of country
Define GNP.
Gross National Product or GNP, is total output earned from domestic businesses both in the country and abroad.
GNP per capita = (Total GNP) / Population of country
Why are GDP per capita, GNI and GNP per capita not so accurate?
GDP, GNI and GNP per capita do demonstrate the living standards of a country, but because not every countries uses USD ($), the exchange rate shows that economists aren’t seeing the true living standards.
What is the PPP?
Purchasing Power Parity or PPP, is a principle used where the purchasing power, or real value of a certain amount of money in a country is used to obtain the real living standards of that nation; e.g. $1 in poor countries will get you a lot of goods, while in developed nations it won’t get much goods.
Give a benefit of using PPP.
The Purchasing Power Parity will help adjust GDP to demonstrate purchasing power of goods in that country, allowing for a more accurate representation of living standards.
How is the volume of goods different from the value of goods in a country?
The volume of goods shows the quantity of goods and services produced within a country whereas the value indicates the monetary worth of these goods and services.
State a limitation of using GDP and GDP per capita to compare living standards.
- GDP and GDP per capita ignore the shadow/hidden economy; the shadow economy is the illegal economy involving the black market and smuggling of illegal goods, cross-border shopping. All this is ignored in the GDP.
Describe another limitation of GDP and GDP per capita to compare living standards.
- GDP and GDP per capita ignores negative externalities such as pollution, which can severely affect health of several consumers.
Give a third limitation of GDP and GDP per capita to compare living standards.
- Economic growth can cause severe inequalities in income, wealth or region and these inequalities are not taken into account by GDP or GDP per capita.
Define happiness economics.
Happiness economics is a branch of economics investigating how happy and content individuals are about their life.
What is the Easterlin Paradox?
The Easterlin Paradox is a theory of the relationship between real income and happiness; it proves that although happiness initially rises with the increase in income, it will stop rising beyond a certain economic threshold. As a result, rich societies tend to be less happier than poorer societies.
Give a problem of comparing developing and developed countries.
Accuracy of statistics differs very dramatically between developed and developing nations; contrary to popular belief, developing countries do produce many goods but the goods they produce are also consumed by them on the market. So no money is made/there is no monetary value.
State another disadvantage of comparing developed and developing countries.
Although developed countries appear successful, what actually happens is that governments increase income at the expense of causing more stress, more congestion and longer working hours.
Give a third disadvantage of comparing developed and developing countries.
Developing nations may sometimes aspire to achieve growth at the cost of health and safety regulations.
Define inflation.
Inflation is the sustained rise in the average level of prices and fall in the purchasing power of money.
What is deflation?
Deflation, or negative inflation, is where there is a decrease in the average price level and slowing down in the rate of prices increasing.
Give a cause of deflation.
Consumers may delay purchasing decisions in the fear that prices may fall as a result of the decrease in average price levels.
What problems can deflation cause?
Deflation can cause a decrease in demand and consumption of goods and services, causing firms to not be so confident about investing. This will significantly harm the AD (Aggregate Demand) as a result.
What is Aggregate Demand (AD)?
Aggregate demand is the total demand of all finished goods and services within an economy.
Give the formula for aggregate demand.
AD = C + I + G + (X - M)
Consumption + Investment + Government spending + (total exports - total imports) = Aggregate demand
What is disinflation?
Disinflation is a fall in the inflation rate, so prices are rising at a slower rate. Unlike deflation, where inflation rate can fall below 0%, in disinflation the inflation rate falls but stays positive.
Give two methods used by the UK to measure inflation.
- CPI (Consumer Prices Index)
- RPI (Retail Prices Index)
What is the basket of goods and services?
The basket of goods and services is a model used by the Office of National Statistics to influence both the CPI and RPI. It contains about 700 goods and services representing typical consumer purchases in the UK, with prices collected from about 150 different locations in the UK.
How are goods typically weighted in the basket of goods and services?
In the basket of goods and services, goods are generally weighted by how significant they are to consumers and how important they are to a consumer’s income; petrol is given a high weighting due to there not being many substitute goods, and how petrol forms a major part of a consumer’s disposable income.
Give a limitation of using CPI to measure inflation rates of households.
CPI is meant to provide a weighted index of goods and services of all households, yet all households are different, with differing rates of inflation as there will be differing baskets of goods.
Give another limitation of using CPI to measure inflation rates of households.
During measurement, the consumer prices index excludes mortgage payments and associated interest; mortgage payments include the biggest item of expenditure in a household. So, by excluding payments for the most used item in a household, this is an inaccurate method of measurement.
State a third limitation of using CPI to measure inflation rates of households.
CPI doesn’t take into account the improvements of quality in goods and services; the prices of several electronic goods and services have fallen despite the stronger quality.
Describe a limitation of using RPI compared to CPI.
During measurement, RPI excludes the top 4% income earners as it doesn’t believe these are typical households, while CPI includes households of all incomes.
What are the three primary causes of inflation?
- Demand-pull inflation
- Cost-push inflation
- Growth of money supply
What is demand-pull inflation?
Demand-pull inflation is a cause of inflation as a result of excessive amounts of demand; there is too much money from consumers, chasing too little supplies of goods and services.
Give a cause of demand-pull inflation.
Reduced taxation; by reducing taxation, this will contribute to higher disposable consumer incomes, so consumers can afford more goods, causing an increase in demand. This will contribute to demand-pull inflation.
Describe another cause of demand-pull inflation.
Another contributor to demand pull inflation is reduced interest rates; with less interest rates, consumers have more spending power on goods and services, increasing demand. This comes as as result of borrowing becoming more popular and saving money becoming less rewarding.
