Document Summary

Week 2: the price level is fixed, and, aggregate demand determines real gdp. An increase in real gdp increases aggregate expenditure, and. An increase in aggregate expenditure increases real gdp. In the keynesian model, all firms are like the grocery store: they set their prices and sell the quantities their customers are willing to buy. If they persistently sell a greater quantity than they plan to and have inventories piling up, they eventually cut their prices and vice versa. On any given day, their prices are fixed and the quantities they sell depend on demand, not supply. Because each firm"s prices are fixed, for the economy as a whole. Aggregate expenditure has four components: consumption expenditure, investment, government expenditure on goods and services, and net exports. Aggregate planned expenditure is equal to the sum of the planned levels of consumption expenditure, investment, government expenditure on goods and services, and exports minus imports.

Which of the following will increase the short-run aggregate supply?

A. an increase in wages

B. a decrease in the price of capital

C. an increase in government spending on education

D. an increase in consumption spending

All the following explain price stickiness except

Question 2 options:

A. firms choose not to adjust prices until they can assess if changes in sales are temporary or permanent.

B.the more firms produce, the lower the average cost of production. Therefore, firms are willing not raise prices as long as they can sell more.

C. firms may be concerned that consumers may be angered by price increases.

D. firms may be concerned that their rivals may not match their price increases.

3. A movement along the short-run aggregate supply curve in response to a change in the price level is called a

	A. determinant of aggregate supply.
	B. revealed cost on aggregate supply.

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 1^st. Please limit your analysis to an expenditure equation containing only personal consumption expenditures (C) and planned investment (I_o). (The aggregate expenditures equation would be limited to AE = C + I_o_.) 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 I_o? 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.

In the AD-AS model, stagflation does not persist, because the working of the self-correcting mechanism of the economy _____ the level of output and _____ the price level until the economy eventually returns to a long-run equilibrium state, where actual output _____ potential output.

	decreases; decreases; falls short of
	increases; decreases; equals
	decreases; increases; exceeds
	decreases; increases; equals
	increases; decreases; exceeds

The LRAS curve is drawn as a vertical line at potential output (Y*) to indicate that

	Y* is independent of the price level and that actual output Y > Y* in the long run
	Y* equals actual output (Y) in the long run
	Y* is independent of the price level and that actual output Y = Y* in the long run
	Y* is independent of the price level
	Y* is independent of the price level and that actual output Y < Y* in the long run

Stagflation arises in the context of the AD-AS model when some external factor causes

	the LRAS curve to shift to the right
	the AD curve to shift leftwards
	the SRAS curve to shift downwards
	the SRAS curve to shift upwards
	the AD curve to shift rightwards

If the SRAS curve is positively sloped, then a decrease in the demand for Canadian-made goods in Europe will lead to _____ in the price level, in the short run.

	either an increase or a decrease
	no change
	an increase
	a decrease
	an initial increase, and then a decrease

Which of the following will shift the aggregate demand curve to the right?

	Consumers become pessimistic about the future
	A new technology is developed that will increase profits
	Income taxes are raised
	Foreign economies fall into recession, reducing their demand for domestic exports
	The government reduces purchases to balance the budget

Suppose a stock market crash decreases the stock of household wealth and therefore causes autonomous consumption to fall. Which of the following is the likely result?

	A leftward shift the AD curve
	There will be no movement of the AD curve
	A movement down the AD curve
	A movement up the AD curve
	A rightward of the shift the AD curve

An economy is characterized by the AD equation P = 200 ? 0.02Y, SRAS equation P = 100 and LRAS equation Y* = 5000. In the absence of any change in policy or exogenous shocks, this economy will achieve a long-run price level of

	100
	110
	120
	90
	105

The AD-AS model depicts a self-correcting economy. This means that the price level in the model adjusts automatically in response to a(n) _____ gap, so as to eliminate the _____ gap in the long run, without requiring any help from government policies.

	recessionary; recessionary
	recessionary; expansionary
	expansionary; expansionary
	output; output
	expansionary; recessionary

The aggregate demand curve shows

	the amount of planned aggregate expenditure (and output) at the current price level
	the amount of planned aggregate expenditure (and output) at an average price level
	the amount of planned aggregate expenditure (and output) at a constant price level
	the amount of planned aggregate expenditure (and output) at various price levels
	the amount of planned aggregate expenditure (and output) at last year's price level

Consider an economy initially at long-run equilibrium with output (Y) equal to potential output (Y*). If the SRAS is positively sloped, then a shift to the right of the AD curve will lead to _____ in the price level, in the short run. In the long run, the SRAS curve will shift to the _____ and the equilibrium will be at __________.

	an increase; left; Y = Y*
	a decrease; right; Y > Y*
	an increase; right; Y = Y*
	a decrease; left; Y > Y*
	no change; left; Y = Y*
