1. Chapter 4: Inflation

1.1. Definition: Inflation is a general and sustained rise in overall price level over time.

1.1.1. Measured by changes in RPI, RPIX, CPI

1.1.2. RPIX (RPI – mortgage interest payments) is the one used by the government and firms

1.2. Demand pull

1.2.1. Aggregate demand shifts out creating a positive output gap. as component is increased Firms increase prices to choke off excess demand Leads to pool of unemployed workers diminishing as firms need to produce more

1.3. Cost-push

1.3.1. Caused by increased wages (unless offset by productivity) rising raw material costs falling exchange rate

1.4. Why it is a problem

1.4.1. Affects fair distribution of income as it diminishes value of fixed incomes e.g. pensioners or workers in weak bargaining postion

1.4.2. Redistributes away from savers towards borrowers as diminishes value of debt therefore you will have gained

1.4.3. Inflationary expectations rise, workers bid up wages leading to wage price spiral

1.4.4. If inflation rises faster than other countries it will make us less competitive

1.4.5. Creates uncertainty leading to loss of confidence and therefore investment decreases

1.4.6. Blurs price signals if prices are constantly changing and so reduces efficiency of market

1.5. Factors that affect the rate of inflation in the real world

1.5.1. wage growth affected by union power, immigration, inflation expectation

1.5.2. immigration increases supply easing supply side constraints

1.5.3. Information technology increases productivity

1.5.4. Globalisation reduces power of domestic firms raising their prices during the boom as their are alternatives

2. Chapter 5: Current Account

2.1. Balance of payments

2.1.1. Capital account is a balance of lending and borrowing

2.1.2. If it is running a current account deficit the economy’s total spending exceeds its total income Deficit of the current account can only be financed through a surplus of the capital account

2.1.3. current account composition: X-M (of goods and services) +/- net income flows refers to interest, profits and dividends that a country receives each year from its ownership of assets abroad +/- net transfers refers to such things like aid donations and payments to institutions like EU and world bank

2.2. Factors that affect it

2.2.1. Demand-Side High aggregate demand leads to rising incomes some of which is spent more imported goods current account worsens firms also import more raw materials

2.2.2. Supply-Side there will be a deficit if there is a lack of competitiveness in a country low productivity means high cost per unit this leads to uncompetitiveness

2.2.3. Inflation Consistently high inflation means expensive exports = worsening current account

2.2.4. Non-price factors quality/design/reliability/warranty

2.2.5. Exchange rate

2.3. exchange rate

2.3.1. Definition: an exchange rate is the price of one currency expressed in therms of another

2.3.2. S.P.I.C.E.D./W.P.I.D.E.C. Depreciating pound exports cost less Imports cost more

2.3.3. value of a currency is determined by the demand for that currency and the available supply called a floating exchange rate

2.3.4. Affects on macro performance depreciation of pount shifts AD out New node increase in exported goods means unemployment will fall as more labour is needed to produce higher profits and so could lead to rise in investment increase in price of imported goods leads to inflation More expensive to import raw materials

2.4. Improving current account

2.4.1. current account is partly cyclical if AD needs reducing contractionary monetary+fiscal polcies is needed

2.4.2. Expenditure switching polcies if depreciation then switch to domestic made products as cheaper

2.4.3. If poor competitiveness then supply-side polcies will be needed increase productivity increase non-price competition

2.4.4. place limits on number of goods coming into the country or tariffs Protectionist policies this is Prohibited by WTO

3.1. what affects

3.1.1. C Exchange rate

3.1.2. I Interest rates Unemployment business confidence Credit

3.1.3. G debt bailout banks unemployment needed fiscal stimulus

3.1.4. S Interest rate

3.2. Aggregate Demand

3.2.1. Consumption Personal Expenditure of households

3.2.2. Investment Interest rate (negative relationship) Household expenditure on new homes Capital buying

3.2.3. Government spending salaries of civil servants

3.3. Savings

3.3.1. Purchase of financial product (asset)

4. Chapter 1: Macroeconomics

4.1. Macroeconomic Objectives

4.1.1. allocative efficiency/increase living standards

4.1.2. Balance of payments

4.1.3. Low inflation (2%)

4.1.4. Full employment

4.1.5. Economic growth

4.2. Output gaps

4.2.1. negative output gap How it works AD is lessened = demand for goods and services is weakened Actual growth is less than trend growth Effects Worsens Current account falling ouput Solutions Monetary Fiscal

4.2.2. positive output gap during p. output gap there is an increase in demand firms increase prices to choke of excess demand because of the increase in prices workers will bid for higher wages if firm passes these higher costs of production onto consumers then this is cost-push inflation

4.3. Economic Cycle

4.3.1. National income Income received from firms for factors of production produced by households J (injections) =

4.3.2. National expenditure Money spent on goods and services produced by firms W (Withdrawls) =

4.3.3. If W > J then output and income will fall and lead to a recession

5. New node

6. Chapter 2: Economic growth

6.1. Economic Growth

6.1.1. E.G. is best defined as the increase in potential level of real output the economy can produce of a given period of time. (long-run)

6.1.2. Percentage change in GDP (Short-run)

6.1.3. Short run E.G. uses spare capacity in the economy, movement from F (inside frontier) to G

6.1.4. Long run E.G. increase total productive capacity, Movement from G to H

6.1.5. Supply side policies increase quantity and quality of the economy’s factors of production

6.1.6. This allows an economy to grow at a more rapid rate also reduces risk of accelerating inflation

6.1.7. More capital goods = greater long term growth

6.1.8. However, for an economy to grow there needs to be sufficient demand

6.2. Distinguishing between totals(/levels) and rates of change

6.2.1. GDP measures the level/total of national output

6.2.2. GDP growth measures how much real GDP has changed in a given time period

6.2.3. A recession exists when real GDP falls for two economics consecutive quarters

6.3. Simple AD/AS analysis and being able

6.3.1. Long run Aggregate supply refers to the total level of output supplied within an economy at any given price level

6.3.2. SRAS is the sum of all individuals firm’s supply curves

6.3.3. AD line is straight because output stays the same in real terms

6.3.4. AD line shows the normal capacity level of output in the economy

6.3.5. aggregate supply refers to the total level of output supplied within an economy at any given price level.

6.3.6. Short run supply is the total of all individual firms supply curves. As price rises firms will supply more in hope of higher profits

6.3.7. Change in the price levels leads to a movement along the long run aggregate demand curve i.e. straight up

6.3.8. AD = G + I + C + (X-M)

6.3.9. If any of these increase/decrease the LRAS will shift out/inwards respectively

6.4. Output Gaps

6.4.1. An output gap will occur when the growth rate in the economy is either above or below the trend rate of growth/ long term economic growth

6.4.2. A negative gap is when the rate of growth is below the trend rate

6.4.3. A positive gap is when the rate of growth is above the trend rate, this will either decrease the deficit or increase the surplus in the balance of payments on the current account

6.4.4. Output gaps occur when output is greater or less than trend output. A recession or boom. A recession is a fall in real output for 2 consecutive quarters. Running below normal capacity means a fall in output and rising unemployment

6.4.5. Chain of reason (negative) Actual output < trend Unemployment rising Solution Expansionary monetary and fiscal polcies

6.5. Index numbers

6.5.1. Number in current year/ number in base year

7. Chapter 3: Unemployment

7.1. Definition of unemployed: is officially classed as unemployed if they are in the population of working age, out of work and actively seeking employment

7.1.1. not searching for work: Housewives, People in education - claimant count and labour force survey are used to measure unemployment - claimant count is people who eligibly passed for benefits

7.1.2. However, discrepancy between the 2, government holds a bit of manipulation over figures through definition of unemployed pushing figure down - Changed from those registered at job centres to those actually collecting benefit - 2 week time lag introduced before someone could be declared unemployed - Anyone under 18 couldn’t register for benefits and went on training scheme - Pressure was put on long-term unemployed to accept a place on a training scheme - People seeking part-time employment became ineligible for benefit

7.1.3. Some people would even argue that it underestimates true unemployment rate - Benefit cheats - May not be seeking unemployment even tho benefited - Moving between jobs

7.1.4. - Labour force survey (LFS) measuremen of 60000 households

7.2. Causes of Unemployment

7.2.1. Cyclical Occurs when there is a negative output gap when aggregate demand is too low When not enough demand firms will make workers redundant During recessions unemployment inevitably rises as firms close Can be solved with demand side policies

7.2.2. Structural When sector shifts occur and there is a decline in old industry Workers with now useless skills cannot find a job Caused by deindustrialisation Solutions: offer training programs to obtain new skills,example of supply side policy

7.2.3. Frictional Caused when people move between jobs if earning a lot and then made redundant they wont instantly accept a new low-paid job but wait and search for an equivalently paid job Labelled as voluntary unemployment Could be argued that long search periods arise because of the availability of benefits and the real value should be reduced Individual has imperfect information so will take time to search

7.2.4. Seasonal Caused from regular change in weather conditions and holidays such as Christmas; higher employment . Affects tourism agriculture and construction

7.2.5. Classical When markets fail to clear Wage price is higher than equilbrium price usually caused by minimum wage i.e. too much union power

7.3. Solutions

7.3.1. Demand-Side Solves Cyclical Solution to negative output gap to raise aggregate demand

7.3.2. Supply-Side Improving available information, cutting unemployment benefits (e increasing incentive to find a job and reducing search time) Increase Geographical mobility by government grants luring investment, infrastructure, housebuilding Occupational mobility grants education and training See table in revision booklet

7.4. Costs of unemployment

7.4.1. Loss of income for individual and skills if out of work for a long time

7.4.2. Government has to pay benefits and loses tax revenue

7.4.3. Economy loses output as a whole
