From the 1930s until the 1970s, Keynesian economics was usually explained with a different model, known as the expenditure-output approach The Keynesian cross diagram is a formulation of the central ideas in Keynes' General Theory.It first appeared as a central component of macroeconomic theory as it was taught by Paul Samuelson in his textbook, Economics: An Introductory Analysis.The Keynesian Cross plots aggregate income (labelled as Y on the horizontal axis) and planned total spending or aggregate expenditure (labelled as AD.

- GDP = .94 (GDP - 25) + 87 + 15 + 25. We can multiply .94 times GDP and 25 to get: GDP = .94*GDP - 23.5 + 87 + 15 + 25. Subtract .94 GDP from both sides to get: .06*GDP = 87 + 25 + 15 - 23.5. Now add up the terms on the right hand side, then divide both sides by .06 to get: GDP = (87 + 25 + 15 - 23.5)/.06 = 1,725
- In the expenditure-output or Keynesian cross model, the equilibrium occurs where the aggregate expenditure line (AE line) crosses the 45-degree line. Given algebraic equations for two lines, the point where they cross can be readily calculated. Imagine an economy with the following characteristics. Y = Real GDP or national income. T = Taxes = 0.3
- The Keynesian model is slightly more complicated than the classic model, and it is developed in four stages by analyzing four separate models. Each model has, however, a value in itself. The models we will consider and the major characteristics of each are: Cross model: W, P and R are constant (and exogenous)

As presented by students of Keynes. In this graph: Expenditure is represented by E (in the equation and on the vertical axis). It is made up of Income, interest rate minus inflation (real interest rate), government spending, and taxation. If the interest rate increases investment is lower and aggregate expenditure falls (shown in graph) How can the multiplier be used to analyze the economic impact of professional sports? Attracting professional sports teams and building sports stadiums to create jobs and stimula solves a Keynesian-cross-like equation dY = dG MdT +MdY (1) Since this equation characterizes the entire dynamic path of output and stems from a micro-founded model, we refer to it as the intertemporal Keynesian cross. The central object in the in-tertemporal Keynesian cross is the matrix M = (Mt,s) of partial derivatives Mt,s ¶Ct/¶Ys. Fo

- In Keynesian model equilibrium level of income or output is one where total output (GNP) is equal to aggregate demand. It can be expressed by the equation: Y = A
- us the marginal propensity to consume: Y = (a + I + NX + G) × 1/(1 − mpc)
- The Keynesian Theory states that an increase in production leads to an increase in the level of income and therefore, an increase in spending. The value of MPC allows us to calculate the size of the multiplier using the formula: 1 / (1 - MPC) = 1 / (1 - 0.5) = 2. It means that every $1 of new income will generate $2 of extra income
- Averaging this with those who spend a substantial portion of their disposable income could bring MPC to 100%. If this happens, then the multiplier (1/ (1-MPC)) becomes infinite and then Y increases infinity for any increase in government spending or reduction in taxation

virtue. From the perspective of the Keynesian cross, however, thriftiness is a vice. d. In the classical model of Chapter 3, the paradox of thrift does not arise. In that model, output is fixed by the factors of production and the production technology, and the interest rate adjusts t Firms are assumed to make no tax payments; all taxes are paid by households. The central proposition of the simple Keynesian model (the SKM) is that national output (income) reaches its equilibrium value when output is equal to aggregate demand. In the SKM the condition for equilibrium can be expressed as: Y = E - (1

** IS curve is a schedule/curve that shows the equilibrium output level that occurs in the market for goods and services at different levels of interest**. The IS curve is one part of the IS-LM model and it is plotted with interest on y-axis and output on x-axis. The equilibrium in the goods market depends on the interplay of aggregate demand (expenditure) and income The Keynesian Growth Model .

- The Keynesian model assumes that there is some level of consumption even without income. That amount is $236 - $216 = $20. $20 will be consumed when national income equals zero. Assume that taxes are 0.2 of real GDP. Let the marginal propensity to save of after-tax income be 0.1
- The expenditure-output model or Keynesian cross diagram shows how the level of aggregate expenditure (on the vertical axis) varies with the level of economic output (shown on the horizontal axis). Since the value of all macroeconomic output also represents income to someone somewhere else in the economy, the horizontal axis can also be interpreted as national income

too optimistic in seeing fiscal policy as a panacea, the legacy of Keynes' ideas is very much with us today. 11.1 Lord Keynes and the Great Depression When the economies of the world were mired in the deep and prolonged recession of the 1930s known as the Great Depression, British economist John Maynard Keynes, later Lord Keynes, declared tha The Keynesian models to be considered are short run in nature in that the productive capacity of the economy is taken as given. That means the effect of investment on productive capacity is abstracted from and only its impact on current demand and income is taken into account 1. Use the Keynesian cross to predict the impact on equilibrium GDP of the following. In each case, state the direction of the change and give a formula for the size of the impact. a. An increase in government purchases. b. An increase in taxes. c. Equal-sized increases in both government purchases and taxes.2 Simple Keynesian Model is, as its name suggests, the most basic model in the Keynesian family. Although highly abstract (even by the standards of macro models), the Simple Keynesian Model is helpful for its ability to highlight the fundamental equilibrating forces common to all Keynesian macro models

2.2 of the IB Economics Syllabus - The Keynesian Multiplier. Multiplier explanation, multiplier definition, multiplier formula, mathematical example The Keynesian cross model also includes a line called the aggregate expenditure schedule, which illustrates the economy's total expenditures for each possible level of real GDP. It is at the intersection of this line and the 45-degree line where the economy can be thought of to be at equilibrium 3 Example The demand-supply model in microeconomics includes demand function and supply function y1 is the quantity of good; y2 is the price If b1 < 0; b2 > 0; then (1) is the demand function while (2) is the supply function; u1 is the demand shock and u2 is the supply shock. Another example is the Keynesian cross (45 degree line) model in which y1 is the national.

The 45 degree line represents the Keynesian equilibrium condition, so it has the equation PAE = GDP The slope of the 45 degree line is 1. _FALSE_19. The Keynesian cross representation of the consumption function was not the work of John Maynard Keynes, but of his father, John Neville Keynes According to the Keynesian cross model, if the marginal propensity to consume is 0.9, and government spending rises by $200, then equilibrium output rises by $380 In the Keynesian model of aggregate expenditure, autonomous consumption plays an important role.

** Aggregate Expenditure Model: Keynes reformulated the model, so that investment still depend on the rate of interest, but savings and consumption depend on disposable income, and the interest rate**. We will start with a discussion of a simple model, in which Savings depends only on disposable income, an Keynesian cross model has a number of limitations. The first one is the fact that not all of gross private domestic investment counts as part of aggregate demand (Dolan & Lindsey, 1994, p.139). This means that the aggregate demand is undervalued since some investments, which need increase aggregate demand is left out Keynesian Multiplier . The Keynesian multiplier represents how much demand each dollar of government spending generates. For example, a multiplier of two creates $2 of gross domestic product (GDP) for every $1 of spending. Most economists agree that the Keynesian multiplier is one. Every one dollar, the government spends adds $1 to economic growth 0 reviews for Income and expenditure: Keynesian cross and IS-LM model online course. Consumption function.

model. This paper presents a modernized alternative, the intertemporal Keynesian cross, that addresses these weaknesses and captures the general equilibrium feedback mechanisms in a variety of dy-namic macroeconomic models. It has the form dY = ¶Y +MdY (2) which is an intertemporal generalization of (1), with Y being the vector of output at. These propositions were later formulated by Paul Samuelson into what is now known as the Keynesian cross model.3 This model has become one of the standard elements of undergraduate macroeconomics courses. Figure 1 shows a diagrammatic representation of the Keynesian cross, as generally presented in contemporary macroeconomics textbooks Term Keynesian cross Definition: The standard diagram used in Keynesian economics to identify the equilibrium level of aggregate output (that is, gross domestic product), with aggregate expenditures measured on the vertical axis, and aggregate output measured on the horizontal axis.This diagram contains two key lines, the aggregate expenditure line and the 45-degree line This graph should make clear why the model is called a Keynesian cross. This is because the (ZZ) and (YY) curves cross to determine output. This pedagogical device to visualize the Keynesian multiplier was introduced in 1948 by Paul Samuelson in his famous Economics textbook, to provide a geometric intuitive interpretation of Keynes' ideas

You need to think about the Keynesian Cross model to understand the IS relation. Remember the effect of increasing I on the Keynesian Cross, means you shift the planned expenditure curve up, and you get a higher equilibrium level of Y. So higher I = higher Y. This is basically what happens when you move down the IS curve New Keynesian models have been extensively used to study macroeconomic dy-namics and to design and analyze monetary policy rules (Clarida, Galí, and Gertler, For some speciﬁcations cross-equation restrictions emerge in the log-linearized equations describing household and ﬁrm behavior Keynes believed that the problem during recession is inadequate spending. He uses Keynesian cross to model this insight.

TRUE. 6.In a simple Keynesian model (with lump-sum taxes and a MPC of 0.8), if the government increases spending by $400 billion and increases taxes by $400 billion, output will increase by $400 billion. TRUE Two-Sector Model: A two-sector model of income determination of an economy consists only of domestic and business sectors. Assumptions: The income determination in a closed economy is based on the following assumptions: 1. It is a two-sector economy where only consumption and investment expenditures take place 10. According to the analysis underlying the Keynesian cross, when planned expenditure exceeds income: A) income falls. B) planned expenditure falls. C) unplanned inventory investment is negative. D) prices rise. 11. In the Keynesian-cross model, as the interest rate increases, the equilibrium level of income _____ The Keynesian cross model of under-employment equilibrium is explained in Figure 2 where income and employment are taken on the horizontal axis and consumption and investment on the vertical axis. Autonomous investment is taken as a first approximation

the long run model of Chapter 3, output is constant, so the interest rate must adjust enough to cause complete crowding out. In the Keynesian Cross model, the interest rate is xed, so there is no crowding out and output must rise enough to cover the extra spending (or equivalently to restore saving to its original level) Many of you will have spent quite a lot of time looking at '45 degree' diagrams, or 'Keynesian cross' diagrams. Until a few years ago, they were the main way in that the expenditure and income aggregates where analysed. Nowadays, aggregate demand and supply diagrams are preferred, although many teachers still like to explain the situation using the 'good old' 45-degree diagram The Keynesian Model of Income Determination This set of notes outlines the Keynesian model of national income determination in closed and open economy. It then shows how to solve for multipliers. 1.

The Keynesian cross is a graphical depiction created by Paul Samuelson in order to elucidate Keyness basic ideas, which firs

Consumption function formula. C = a + b Yd; This suggests consumption is primarily determined by the level of disposable income (Yd). Higher Yd leads to higher consumer spending. This model suggests that as income rises, consumer spending will rise.
