Document Summary

Ec 140- lecture 7: chapter 21 & 22. Changes in equilibrium national income: list up: higher investment, higher wealth, lower interest rate, higher expected income, list down: higher interest rate, lower wealth, lower investment. Multiplier: the ratio of the change in equilibrium income due to the change in the autonomous component of ae: the simple multiplier is derived from the equilibrium of the model. G has a clear direct e ect on ae- it is one of its components. If g increases by ae will increase by (all else held constant) Taxes examples: personal income tax, corporate income taxes, sales tax. Monday, january 28, 2019: excise taxes on products. Transfers examples: old age pension, welfare disability, new child transfer. Intuition: almost all taxes rise with income or spending. Transfers that are clearly sensitive to income are e. i payments & welfare. Desired exports (x)exports depends on decisions made by foreigners and are.

Assignment 4 (Chapter 23) Sequestration 2013

Dear Colleagues,

Using the goods and services model from the text (what I have labeled the 'Commodities Model' in my syllabus or the Keynesian Cross), please offer a basic analysis of the sequestration of expenditures by the Federal Government that took effect on March 1st. Please limit your analysis to an expenditure equation containing only personal consumption expenditures (C) and planned investment (Io). (The aggregate expenditures equation would be limited to AE = C + Io.) Please note that I want you to ignore the impact of any direct reduction in governmental expenditures upon aggregate expenditures as is discussed in chapter 24. In particular, discuss and model the effects of the Sequestration on C. Also, would there be a possible effect on Io? Please explain the conclusions that you reach. Before beginning your analysis please read the articles listed below:

Sequestration: The Truth Behind The Spending Cut€, Mani.

http://www.istockanalyst.com/finance/story/6318811/sequestration-the-truth-behind-the-spending-cuts

Paragraph 7 in particular in the article above

Fiscal Multipliers, the IMF & the OBR, Weldon, Duncan.

http://touchstoneblog.org.uk/2012/10/fiscal-multipliers-the-imf-the-obr/

Deleveraging Shocks and the Multiplier (Sort of Wonkish)€, Krugman, Paul,

http://krugman.blogs.nytimes.com/2012/10/09/deleveraging-shocks-and-the-multiplier-sort-of-wonkish/

In your analysis, please use the Keynesian Theory of Consumption as the model to represent household expenditures. You may assume that the aggregate expenditure function (line) has only consumers and business, and business expenditures are not dependent upon income (as presented in the text).

Of what importance is the discussion of the multiplier mentioned in the last two articles?

Is it possible that business expectations about the future will change?

What would change in the model as a result of this change in expectations (Please discuss the potential impact on inventories)?

As you perform your analysis, you do not have to specify exact values on the axes. Your response will be graded upon your ability to determine the direction in which incomes will change, either increasing or decreasing, due to the sequestration and if the change will be large or small. (Recall that income, Y, is represented on the horizontal axis in the Keynesian Cross model.) In your model, be sure to begin your analysis with aggregate expenditures at pre-sequestration levels and equilibrium income. Then indicate the appropriate movement of the consumption function and business planned investment and the effect on equilibrium income.

Also, provide a brief explanation of how unplanned investment would change as a result of the sequestration and how the unplanned investment causes equilibrium income to increase or decrease.

On the planet Omicron Persei 8, government spending is $1000, net taxes are $1200, and planned investment is $1400. Consumers spend according to the equation C = 100 + 0.8Yd, where Yd represents disposable income. Given this information, fill out the table below to determine which of the output levels represents a macroeconomic equilibrium, then answer the questions that follow. Output (Income) Y Net Taxes T Disposable Income Yd Consumption C Planned Investment I Government Purchases G Planned Aggregate Expenditure AE Unplanned Inventory Change 6200 1200 5000 3850 1400 1000 6250 -50 6700 1200 5500 4225 1400 1000 6625 75 7200 1200 6000 4600 1400 1000 7000 200 7700 1200 6500 4975 1400 1000 7375 325 8200 1200 7000 5350 1400 1000 7750 450

An a. Which level of output is a macroeconomic equilibrium? There is no level of equilibrium based on inventory levels.

b. Is the government budget balanced, in deficit, or surplus, and by how much? Since the government is spending less than it is collecting in taxes, we are showing a surplus.

c. Find the marginal propensity to consume, and the marginal propensity to save. d. Find the government spending multiplier. If the government wanted to increase the equilibrium level of income by $1,000, how much would it have to increase government purchases? e. Find the tax multiplier. If net taxes were lowered by $100, what effect would it have on the equilibrium level of income? Give a specific numerical answer.
