Slide1: 9 The Economy and Business Activity


Macroeconomic Objectives: Macroeconomic Objectives Microeconomics and macroeconomics The major macroeconomic issues economic growth unemployment inflation balance of payments and exchange rates Government macroeconomic policy controlling various intermediate variables interest rates, money supply, taxes, government expenditure, etc.


The Circular Flow of Income: The Circular Flow of Income The inner flow


Slide4: The circular flow of income Firms Households


The Circular Flow of Income: The Circular Flow of Income Withdrawals net saving (S) net taxes (T) import expenditure (M) Injections investment (I) government expenditure (G) export expenditure (X)


Slide6: Factor payments Consumption of domestically produced goods and services (Cd) The circular flow of income WITHDRAWALS INJECTIONS


The Circular Flow of Income: The Circular Flow of Income The relationship between withdrawals and injections the links between them planned injections may not equal planned withdrawals effect of J > W effect of W > J equilibrium in the circular flow


Slide8: Factor payments Consumption of domestically produced goods and services (Cd) The circular flow of income WITHDRAWALS INJECTIONS


The Circular Flow of Income: The Circular Flow of Income The relationship between withdrawals and injections the links between them planned injections may not equal planned withdrawals effect of J > W effect of W > J equilibrium in the circular flow The circular flow and the four macroeconomic objectives


The Determination of Business Activity: The Determination of Business Activity The importance of aggregate demand effects of J > W effects of W > J Identifying the equilibrium level of GDP the 45o line diagram


Equilibrium GDP: O GDP (£bn) GDP = Cd + W Cd, E, W, J (£bn) Equilibrium GDP


The Determination of Business Activity: The Determination of Business Activity The importance of aggregate demand effects of J > W effects of W > J Identifying the equilibrium level of GDP the 45o line diagram the GDP and E lines


Equilibrium GDP: O GDP (£bn) GDP = Cd + W Cd, E, W, J (£bn) Equilibrium GDP


The Determination of Business Activity: The Determination of Business Activity The importance of aggregate demand effects of J > W effects of W > J Identifying the equilibrium level of GDP the 45o line diagram the GDP and E lines effects of E > GDP effects of GDP > E


Equilibrium GDP: O GDP (£bn) GDP = Cd + W Cd, E, W, J (£bn) GDP1 GDP2 Equilibrium GDP


The Determination of Business Activity: The Determination of Business Activity The importance of aggregate demand effects of J > W effects of W > J Identifying the equilibrium level of GDP the 45o line diagram the GDP and E lines effects of GDP > E effects of E > GDP finding the equilibrium point


Equilibrium GDP: O GDP (£bn) GDP = Cd + W Cd, E, W, J (£bn) GDP1 GDP2 GDPe Equilibrium GDP


The Determination of Business Activity: The Determination of Business Activity The multiplier the multiplier process definition of the multiplier GDP / J the marginal propensity to consume domestic goods and services mpcd = Cd / GDP


The multiplier: a rise in aggregate expenditure: O GDP (£bn) 100 160 100 120 160 Cd, E, W, J (£bn) The multiplier: a rise in aggregate expenditure


The Determination of Business Activity: The Determination of Business Activity The multiplier the multiplier process definition of the multiplier GDP / J the marginal propensity to consume domestic goods and services mpcd = Cd / GDP formula for the multiplier 1 / (1–mpcd)


The multiplier: a rise in aggregate expenditure: O GDP (£bn) 100 160 100 120 160 Cd, E, W, J (£bn) The multiplier: a rise in aggregate expenditure


The Business Cycle: The Business Cycle Growth in actual and potential output Economic growth & the business cycle fluctuations in actual growth the phases of the business cycle the upturn the expansion the peaking out the slowdown or recession

The Business Cycle: The Business Cycle Causes of cyclical fluctuations Why does AD change in the first place? Why do booms and recessions persist? time lags bandwagon effects the accelerator Why do booms and recessions end? ceilings and floors echo effects the accelerator random shocks changes in government policy


Money, Interest Rates and Business Activity: Money, Interest Rates and Business Activity The meaning of money narrow definitions of money (M0 in the UK) broad definitions of money (M4 in the UK) The supply of money banks and the creation of credit simple illustration

Money, Interest Rates and Business Activity: Causes of increases in money supply increased demand for money banks reduce liquidity ratio inflow of funds from abroad a public-sector deficit (PSNCR) depends on how it is financed from banking sector: money supply expands from outside the banking sector: money supply does not expand Money, Interest Rates and Business Activity
