discuss keynesian model of income determination

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. KEYNESIAN MODEL VIII. Saving is a function of income, i.e. and the value of the expenditure multiplier. The four aggregate expenditures are consumption expenditure (C), investment expenditure (I), government expenditure (G), and net exports (X – M).   Keynesians believe consumer demand is the primary driving force in an economy. The national income will be in equilibrium only when intended saving is equal to intended investment. D) all of the above since computers are consumer durables. § Key Assumption: 1.Prices are constant,at given price level firms are willing to sell any amount of the output at that price level. In other words, it is the state where either macroeconomic sectors viz. ACHIEVMENT OF FULL EMPLOYMENT VII. 1. Know the components of Total Expenditure. Total income (Y) = Total Expenditure (TE) = GDP. The two major composition of equilibrium are aggregate production/output and aggregate expenditure. 7) Actual investment spending is comprised of two components: KEYNESIAN III. Aggregate demand comprises of two components: Keynesian Theory of Income and Employment! Subject : economics Course :Post Graduate Keyword : SWAYAMPRABHA A) consumers on personal computers. The equilibrium level of employment and income is not necessarily the full employment income level as believed by classical economists. 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. Aggregate Output < TE… firms increases output. Y = AD = C+ I + G + (X-M) or Y = C+ I + G + (X-M) Keynes gives all attention to the ADF. Classical Theory of Income and Employment, 2. An Expanded Model and Equilibrium Eq.No. The point of effective demand, which gives the equilibrium level of employment, also indicates the equilibrium level of national income and output. household, firms, government, and foreign sector, do not purchase the quantities that have been produced, or the state when producers or business firms are unable to meet the demands or sell the goods they have produced. Inventories decline since consumer purchases are greater than actual production made by the firms. A comparison of the classical and the Keynesian models of income determination are given below: The classical and the Keynesian models, given above in the notational form, refer to the working of the macro – level economic system in three markets, i.e. We should note that C and AD are also endogenously determined by the forces in the model. The Keynesian Theory Keynes's theory of the determination of equilibrium real GDP, employment, and prices focuses on the relationship between aggregate income and expenditure. Components of GDE = C + I + G (only) The Basic Framework of the Keynesian Model  This model suggests that TE drives the economy  Along the 45 0 line, the economy is at equilibrium TE Y (Aggregate income and aggregate output) 45 0 TE = Y Along this 45 0 line the amount on the vertical axis is exactly equal to the amount on the x-axis.
