theme 2 Flashcards
what is the circular flow of income?
its a model of the economy where the major exchanges are represented as flows of money, goods and services etc between economic agents
what are the three withdrawals from an economy?
savings, government taxation, imports
what is the effect of withdrawals?
decreases the size of national income
what is the definition of GDP?
the market value of all the final goods and services produced in a given country
includes both citizens and non citizens within a country
what does nominal value mean?
its the breakdown of characteristics of an economy
what does GNI mean?
the total income generated by a countries citizens?
what is GNP?
the market value of all goods and services produces in one year by labour and properyty supplied by the citizes of a country
what are the evaluations of economic growth?
to what extent does it measure wellbeing effectively?
depends on how growth is achieved?
which groups in society benefit the most?
are you just considering growth in the short term?
magniture of benefits compared to costs of growth?
what is the balassa-samuelson effect?
when the prices of goods and services in poorer countries are cheaper because they are immobile
what is arbitrage?
when goods are purchased for cheap and resold at a higher price elsewhere
what is PPP and how is it calculated?
PPP compares a basket of goods + services and changes in price to reflect different costs of living and inflation.
to calculate: volume of goods produced by each country x price of the good in the US
what are the benefits and limitations of PPP?
no discrepancies
provides a base for comparison
however not all goods have an equivalent in the US
what is purchasing power?
the amount of goods you can get for one unit of currency
recall the characteristics of AD
purchasing power
interest rates
exports/imports
how does purchasing power affect AD?
people can purchase more with their income
assets worth more
induces the wealth effect
leads to higher consumption and investment
how does interest rates affect AD?
borrowing is cheaper
saving less attractive
higher consumption
how does exports/imports affect AD?
if prices are low, uk prices are more competitive compared to other countries]larger quanitity of exports sold
people opt for cheap UK goods, so imports fall
how do you calculate MPC?
change in consumption/ change in income
what are the factors affecting consumption?
consumer incomes
availability of credit
consumer confidence
changes in taxation
population
wealth effect
inflation expectations
what are the factors affecting investment?
paradox of thrift
economic growth
business expectations + confidence
demand for exports
interest rates
access to credit
government and regulation
relative prices of capital and labour
what are the factors affecting SRAS?
exchange rates
changes in taxation
cost of raw materials
how does changes in taxation. cost of raw materials and exchange rates affect SRAS?
taxation inc leads to inc in cost of production
increase cost of raw materials, inc cost of p
if exchange rate depreciates, cost of raw materials increases
all of these shift SRAS inwards
what is the definition of aggregate supply?
the potential output of all goods and services that are produced within an economy over a period of time
what are the factors affecting net trade?
relative inflation
exchange rates
cost of production
what is actual growth
Actual economic growth occurs when the current output level is below full capacity and therefore an increase in AD can lead to higher real GDP in an economy
what is an output gap
an output gap is the difference between real output (Y1) and potential output (Y*)
how can you evaluate the multiplier?
- There is a time lag involved- may not feel the effects until a later stage
- Measuring the multiplier effect may be difficult as it is hypothetical
- If the economy is close to full employment it may cause inflationary pressure
- MPM of a country may be high, which means that consumers are more likely to spend an additional unit of income on imports, which is a withdrawal from the economy
- If MPC is low, the rounds of spending will be lower
what are the two formula to calculate the multiplier? how do you calculate MPW?
1/MPW
1/(1 - MPC)
MPW= MPS + MPM + MPT
what are the macroeconomic objectives?
- Low unemployment
- Low+ stable rate of inflation
- Current account surplus
- Economic growth
- Balanced govt budget
- Balance of payment equilibrium
- Income equality
- environment
what are the targets for the govt macroeconomic objectives?
Target for inflation is 2%
Unemployment target is 3%
Target for balance of payments – 5% of GDP= sustainable
Economic growth- sustainable growth
why is strong economic growth needed
You need strong economic growth to increase employment as it creates new jobs-> higher incomes, reduce negative output gaps, inc c + I, increase LRAS
what is a current account deficit?
a current account deficit is when the outflow of money is greater than the inflow of money
what is the evaluation for the net impact of a current account deficit on the value of the pound?
more imports than exports means that supply inc is greater than demand in, net impact means that the value of the pound falls
what is the effect of a current account deficit on exchange rates if uk exports are high?
if uk exports are high, the demand for the pound is high, because to buy uk exports you have to buy the currency. So a current account deficit would cause for the exchange rate to appreciate
what is the effect of a current account deficit on exchange rates if uk imports are high?
if imports are high, the supply of the pound increases as people in the UK need to supply the pound in order to buy foreign currencies, so a current account deficit leads to the exchange rate depreciating
what is disinflation?
when level of inflation is falling, meaning that prices are rising more slowly
what is hedging
Hedging is when there is an agreement between firms and their supplier to purchase the good at a fixed price, which can delay cost push inflation
