Know the components of Total Expenditure. Aggregate expenditure is the expenditure on final goods and services that are carried out by different macroeconomic sectors including household, firms, government, and foreigners. In this unit, we explore one of the intellectual developments from this era that reshaped how many economists think about national income determination. When output is in excess of planned aggregate expenditure, output exceeds purchases, and inventories accumulate. Inventory starts accumulating since consumers are buying less than what is being produced by the firms. The Keynesian Model of Income Determination This set of notes outlines the Keynesian model of national income determination in closed and open economy. 7. § Key Assumption: 1.Prices are constant,at given price level firms are willing to sell any amount of the output at that price level. 4. Definition : In economics, the 45 degree line illustrates a variety of economic phenomena. Thus, if Y > AE or AE < Y. What other factors determine C? 2. S=f (Y). Want to read all 11 pages? ACHIEVMENT OF FULL EMPLOYMENT VII. KEYNESIAN THEORY IV. In this unit, you'll learn how the aggregate supply and aggregate demand model helps explain the determination of equilibrium national output and the general price level, as well as to analyze and evaluate the effects of fiscal policy. (That amount that you will spend, even if Y=0, spent from. If more inventories accumulate than what was expected, it means that actual investment (I) is greater than planned investment (IP). Note: Although the Neoclassical model is more realistic than the Keynesian model, students are allowed to use either model to illustrate the aggregate demand-aggregate supply approach to determining the equilibrium national output/national income in the examination. You'll also learn about the impact of economic fluctuations on the economy’s output and price level, both in the short run and in the long run. So Total Expenditure(TE)/ Aggregate Expenditure (AE): The Basic Framework of the Keynesian Model, This model suggests that TE drives the economy, Horizontal axis: Y (Aggregate Y & Aggregate Output), 45˚ line shows all the possible equilibrium points, E.g. The Keynesian theory of income determination is presented in three models: i) The two-sector model consisting of the household and the business sectors.   Privacy iii) The four-sector model consisting of household, business, government and foreign sectors Q.No.2. The two major composition of equilibrium are aggregate production/output and aggregate expenditure. Saving is a function of income, i.e. The Keynesian theory of employment is also called the theory of income and output. C) governments on personal computers. The Keynesian model considers that, the real GDP consist of four major factors: Aggregate expenditure on consumption. In 1936, Keynes had published The General Theory of Employment, Interest and Money , a book that revolutionised economic theory in the same way that Charles Darwin’s The Origin of Species revolutionised biology. On the IS-LM graph, "IS" represents one curve while "LM" represents another curve. In the Keynesian model of income determination, consumer expenditure includes spending by. An Expanded Model and Equilibrium Eq.No. In the economy, as one man's expenditure is another man's income, the total expenditure of the economy must be equivalent to the total income. Keynesian theory is relevant in the context of the short run only since the stock of capital, techniques of production, efficiency of la­bour, the size of population, forms of business organisation have been assumed to remain constant in this theory. The theory states that equilibrium level for national income is determined when aggregate demand is equal to aggregate supply. DETERMINATION OF EMPLOYMENT V. DETERMINATION OF INCOME AND OUTPUT VI. Classical Theory of Income and Employment, 2. 1. Aggregate Output < TE… firms increases output. B) businesses on personal computers. The Keynesian income-expenditure model explains the relationship between the expenditure and current national income. 6) In the Keynesian model of income determination, consumer expenditure includes spending by. product, labour and money. Aggregate Output > TE… firms reduces output, E.g. Explain factors which determine the level of consumption (C), Investment (I), Government expenditure (G), Exports (X) and, Illustrate and interpret the Consumption function and the Savings, Explain and calculate autonomous, induced expenditure, marginal, propensity to consume (MPC) and the marginal propensity to save. In addition, he believed that the equilibrium level of national income can be estimated when AD=AS. MEAP/U2 Topic 5 Simple Keynesian Model of Income Determination MDUtheintactone 2 May 2019 2 Comments According to Keynes, there can be different sources of national income, such as government, foreign trade, individuals, businesses and trusts. Inventories decline since consumer purchases are greater than actual production made by the firms. In other words, it is the state where either macroeconomic sectors viz.
