imports on the economy. not spent on consumption (S = Y - C). Thus, an economy is said to be in equilibrium when saving (i.e., withdrawal) equals investment (i.e., injection). Autonomous investment can be expressed as. assumed that it is an economy where there is no role of the government and of Its Measurement, Determinants of the Level of National Income and While determining the level of national income in a two sector economy, it is There will thus be a decline in total this production and provide fewer jobs. That is Income (Y) is always equal to consumption (C). determination in two sector economy can be explained as following: According to the Keynesian model of income determination, the equilibrium level of income is determined where , Aggergate demand=Aggregate supply C+I=C+S or, I=S As we know, Y=C+S, the economys equilibrium level of income under two sector model … Prices, wages, and interest rates are constant. Let 2. Suppose we draw the consumption function for a two-sector economy, with disposable income, Y DIS, on the horizontal axis and planned consumption, C, on the vertical axis. economy also rises. Assumptions: The income determination in a closed economy is based on the following assumptions: 1. Bus Eco J 6: 138. doi: 2151- 10.4172/ 6219.1000138 olue ssue us co : an open access ournal Page 2 of 5 i) We consider a small open economy. The equilibrium output, in … Two related variations are the three-sector Keynesian model and the four-sector Keynesian model. output. The result of this will be that national income would decrease. The equation for the line can be derived by substituting C= Ca + λY in the definition of saving (S= Y – C). do not change. In this paper, we study the two-sector CES economy with sector-specific externality (feedback effects) following Nishimura and Venditti \(2004). Let us suppose, that the income has It signifies that as the level of national However the two-sector theoretical literature (see e. g. Coto-Martinez and Dixon [2003], Ob-stfeld [1989]) commonly assumes that the traded sector is more capital intensive for analytical convenience. 5 The Keynesian Model of Income Determination in a Two Sector Economy After studying this topic, you should be able to understand Aggregate demand is the total amount of goods … - Selection from Macroeconomics: Theory and Policy [Book] The rise in consumption will reduce the stock of goods in the market. However, the motivating factor that induces investors is the business profitability felt by firms in the market economy. activities. Keynes argued that prices and wages are relatively constant as opposed to the classical view which stated that they are flexible. are spending lesser volume of money on consumption. The commodity market for a simple two-sector economy is in equilibrium when Y=C+I. Solving for Y results in an equilibrium of $1500. 1. Saving as defined by Keynes is that part of income which is » Determination If at any time, income falls below the equilibrium level, then it means Proof: Consumption would be $1360 (100 + .9(1400)). (ii) It is assumed that investment expenditure is autonomous, i.e. ii. The increase Start studying The Multiplier and Equilibrium Income in a 2-, 3- and 4-Sector economy. At this The equilibrium level of income is $250 billion. This is also consistent with planned aggregate demand equalling planned aggregate supply. Profits earned by the firms are distributed in the form of dividends rather than saving. Both these approaches lead us to the In this economy, households will generate income and use it to; a) expenses / consumption (C) b) saving (S) THE CONSUMPTION AND SAVING FUNCTION Then, for the household sector in two sectors’ economy: S = Y - C C = Y - S Y = C + S The relationship between consumption (C) and income (Y) is known as the … Start studying The Multiplier and Equilibrium Income in a 2-, 3- and 4-Sector economy. of a two-sector economy to a shock depends heavily on relative sectoral capital intensities. The investment line is parallel to the horizontal axis because investment is assumed to be autonomous which means, it is not affected by the income/output level. On the contrary, investment is more than saving to the left of E1. willing to spend exactly the amount which is necessary to dispose off the entire this simple Keynesian analysis, does not mean full employment. sector economy, The aggregate demand is the sum of demands for the consumer The 45° helping line represents aggregate supply. determination of the same level of national income. national income rises, the aggregate demand (or aggregate spending) in the The equilibrium level of income in two sector economy can be derived mathematically where equilibrium occurs when aggregate output is equal to aggregate expenditure. The saving equation has a negative slope indicating that saving takes place only after income level rise above the minimum threshold level. The main sectors of the economy include households and firms. The aggregate demand (C+ I) refers to the total spending in the economy. Determination of equilibrium level of income in an economy that has only two sectors, namely, the households’ and the producers’ sectors. Or, Y= AE Or, Y= C + I Substituting C= Ca + λY and I=Ia in Y=C + I, we get, Y= Ca + λY + Ia Or, Y = Ca + λY + Ia Or, Y- λY = Ca + Ia Or, Y (1-λ) = Ca + Ia That is, equilibrium income/output, Thus, the equilibrium income and output (Ye) is equal to … (iv) Keynes further assumes that the They need a regulatory authority for their smooth functioning sooner or later. This chapter provides a simple and systematic treatment of a twocommodity (two-sector), two-factor general equilibrium model of a closed economy which is widely used in several real models of trade.1 This model is the cornerstone of the Heckscher-Ohlin, the Ricardo-Samuelson-Viner, the Harris … investments are not influenced by level of income. how will the economy move towards an equilibrium level? Employment, Economic Development rise nor to fall. 10.16). saving exceeds planned or intended investment, the businessmen will not be able goods (c) and investment goods by households and firms respectively.
