Discuss the determinants of aggregate demand and distinguish between a movement along the aggregate demand curve and a shift of the curve. Discuss the determinants of the four components of aggregate expenditure. Discuss the determinants of aggregate supply, and distinguish between a movement along and a shift of the curve. Textbook reading: Chapter 5 p112, pp127-136 (Business cycles) Chapter 9 pp229-231, 234-239 (Components of Agg Expenditure) Chapter 10 pp267-272 (Agg Demand), pp275-279 (Agg Supply), pp280-283 (Equilibrium AD-AS) Vocational Business Education Slide 1 Slide 2 Business Cycle The business cycle refers to the periodic but irregular ups and downs in the level of growth in economic activity over a period of time. The economy grows over time, but there are irregular fluctuations in its rate of growth from year to year. Vocational Business Education 2 Slide 3 Business Cycle Measured by % change in RGDP. In most economies economic activity tends to assume a 4 phase cycle: Expansion-Peak-Contraction-Trough Real GDP % change Time Peak Contraction Expansion Trough Vocational Business Education 3 Slide 4 Business cycle A complete business cycle occurs when the of economic activity level fluctuated between peak and peak or trough and trough. There can be variations in: The intensity (amplitude) of the cycle The size of fluctuations in economic activity The duration of the cycle The time taken for economic activity to go through a complete 4-phase cycle. Vocational Business Education 4 Slide 5 1. The Expansionary phase The phase in which economic activity (% change in Real GDP) increases from a preceding period of slowing or declining economic growth. Characteristics of expansionary phase GDP increases at a higher rate than in the preceding period Employment tends to increase /unemployment to decrease Inflation tends to increase Business and consumer confidence increases, reflected by higher C and I spending. Household savings tend to decrease / borrowings increase). Consumption patterns change: consumers buy more expensive and durable products e.g.: Motor vehicles Capacity utilisation of firms increase.as prod’n levels come closer to 100% of full potential productive capacity Vocational Business Education 5 Slide 6 2. Peak [boom] Phase The economy experiences its highest level of economic activity (Max. growth in Real GDP) Low levels of unemployment Maximum unfilled employment vacancies Increasing inflation (esp. demand-pull inflation) Increasing wage levels, due to scarcity of labour High levels of business & consumer confidence. Imports generally increase to meet unsatisfied domestic demand for goods and services. Vocational Business Education 6 Slide 7 3. Contraction Phase The rate of economic growth declines or slows, e.g. it decreases from 4% to 2% (production slows), 4. The Trough Phase of the business cycle in which the economy experiences its lowest level of economic activity. Real GDP growth is at its minimum. Note: it is minimum growth, not necessarily negative. When Real GDP falls (experiences negative growth) for 2 consecutive quarters, the economy is in a “technical recession”. Vocational Business Education 7 Slide 8 Characteristics of the Trough Increased business bankruptcies High levels of unemployment Further reduction /stabilisation of inflation Further reduction of imports Continuing and worsening decline in consumer and business confidence. Lower levels of I and C spending, and higher levels of sings. Vocational Business Education 8 The Product market: AD-AS model Aggregate Demand Aggregate demand (AD): spending on real GDP by households, firms and the government. The aggregate demand for goods and services has four components: Aggregate Demand = C + I + G + NX Aggregate Supply = Y In equilibrium, supply = demand Therefore, in equilibrium Y = C + I + G + NX Slide 9 Vocational Business Education 10 The aggregate-demand curve Quantity of output Price level 0 Aggregate demand P Y Y2 P2 1. A decrease in the price level ... 2. ... increases the quantity of goods and services demanded. Why is the aggregate-demand curve downward sloping? (the reasons are very different from a D curve for a good) Vocational Business Education 10 AD curve shows the amounts of goods and services (RGDP) that will be purchased at any given price level. Aggregate demand is the relationship between the overall price level and real GDP. In ‘Price and Market’, a demand curve concerns about a substitution and relative price change for particular goods. Also, mention that in a textbook, Inflation rate used in a vertical axis 10 Slide 11 Vocational Business Education Aggregate-demand curve is downward sloping An increase in the price level decreases the value of money because each dollar you have buys less. When the price level increases how much we can buy with $1 decreases. A decrease in the price level results in a movement along the AD curve to the right and An increase in the price level results in a movement along the AD curve to the left. 11 11 Slide 12 Vocational Business Education Aggregate Demand Slopes Downwards 1. The price level and consumption − the wealth effect: - Changes in the price level change real wealth, thus changing the level of consumption spending (C). 2. Interest Rate Effect - P↓ causes nominal interest rate ↓ nominal interest rate ↓ encourages greater investment spending by businesses (I ↑) Higher interest rates result in a movement along the AD curve to the left. 3. The price level and net exports − Foreign Purchases Effect - Higher prices causes consumers to spend less on domestically produced goods and services and more on imported goods and services. This results in a movement along the AD curve to the left. 12 12 Shifts in the Aggregate Demand Curve Quantity of Output Price Level 0 Aggregate demand, D1 P1 Y1 D2 Y2 Many other factors, however, affect the quantity of goods and services demanded at any given price level. Aggregate demand increases to Y2 even if the price level stays put at P1? P2 Y2 13 Vocational Business Education 13 Shifts in aggregate demand In the short run, shifts in aggregate demand cause fluctuations in the economy’s output of goods and services. In the long run, shifts in aggregate demand affect the overall inflation rate but do not affect output. Why the Aggregate-Demand Curve Might Shift Shifts arising from changes to the components of aggregate demand (C) Consumption: consumer optimism, tax rates, prices of assets (stocks, bonds, real estate) (I) Investment: technological progress, business confidence, tax rates, money supply (G) Government Purchases (NX) Net Exports: foreign GDP, expectations about exchange rates Y Vocational Business Education Slide 14 Slide 15 RMIT University Determinants of Consumption Spending Deterrminants are non-price factors that change the level of aggregate demand and consequently result in shifts of the AD curve. Determinants or factors that influence consumption spending The level of personal disposable income (PDI) Changes in tax rates Expectations / Confidence – e.g. future incomes or prices The cost & availability of credit Vocational Business Education 15 15 3-16 Level of Personal Disposable Income (PDI = Gross income – Direct taxes) PDI refers to income available to individuals/ households for either consumption or saving. The level of C tends to increase as PDI increases Changes in direct taxes directly impacts on PDI and may influence the level of consumption expenditure. Generally: Increases in direct tax reduces both
