- What is the Euler equation for consumption, and what is its economicinterpretation?Consider the graphical representation of the Keynesian cross for a hypothetical country, where the planned aggregate spending line is graphed against the 45° line. Suppose that, in this country, there is an autonomous increase in aggregate spending of $20 billion. Show this change on the graph.In the simple Keynesian model, if aggregate expenditure is less than GDP, output will a)decline as firms increase their prices to stop the buildup of inventories b)increase as firms increase production to try to stop depletion of inventories c)remain unchanged indefinitely unless government takes action d)increase as firms cut their prices to try to stop depletion of inventories e)decline as firms cut production to stop the buildup of inventories
- The aggregate expenditures model assumes that the level of net exports is independent from the real GDP true or falseKeynesian economics predicts that if government policy makers deem current equilibrium real Gross Domestic Product (GDP) to be "too low," then an appropriate policy action would be to do nothing, because the economy is self-adjusting. raise government spending, thereby increasing aggregate demand and pushing up real Gross Domestic Product (GDP) with little or no inflationary consequences. increase taxes, thereby causing aggregate demand to increase and inducing a rise in real Gross Domestic Product (GDP) with little or no inflationary consequences. reduce the money stock, thereby causing aggregate demand to decrease and inducing a rise in fall in the price level that generates an increase in total planned expenditures.According to the IS–LM model, what happens to the interest rate, income, consumption, and investment under the following circumstances?a. The central bank increases the money supply.b. The government increases government purchases.c. The government increases taxes.
- In the IS/LM model, the IS curve maps interest rates and saving maps spending and income maps expenditure and money supply maps prices and output maps output and interest ratesAnswer the question on the basis of the following table for a particular country in which C is consumption expenditures, Ig is gross investment expenditures, G is government expenditures, X is exports, and M is imports. All figures are in billions of dollars. Each question is independent of other question using the same table, unless otherwise stated. Price Level C Ig G X M Real GDP 128 $18 $2 $3 $1 $5 125 $20 $4 $3 $2 $4 122 $22 $6 $3 $3 $3 119 $24 $8 $3 $4 $2 116 $26 $10 $3 $5 $1 Refer to the table. The real-balances effect of changes in the price level is: Group of answer choices shown by columns (1) and (5) of the table. shown by columns (1) and (4) of the table. not shown by the data in the table. shown by columns (1) and (2) of the table.Consider the following open economy: C = 40 + 0.85x YD I = 1500 G = 1600 X = 240 M = 0.12x Y TR = 10 T= 0.16V If there is a $180 increase in government expenditure, what is the change in equilibrium real GDP (assuming no change in the price level)? Do not write the dollar ($) sign, and use a minus (-) in front of a decrease. Round your answer at two (2) decimals if necessary.
- The following question relates only to the equilibrium in the goods market IN A CLOSED ECONOMY and asks you to carry out a graphical analysis using both the Keynesian cross diagram together with the IS-MP diagram. >>) Suppose after the government has implemented the reduction in taxation that the central bank wants to keep the level of investment at the same level as before the tax reduction. How can the central bank intervene in the market to achieve this goal? Explain and illustrate graphically how the central bank can keep investment at the same level as before. Is there any additional impact of the central bank intervention on output, consumption and interest rates? If so what is the impact?In the Keynesian model, is aggregate expenditure (AE) exceeds total production an unintended _________ will occur and business will __________. a) inventory reduction; increase production b) inventory reduction; decrease production c) inventory reduction; not change production d) inventory accumulation; decrease production e) inventory accumulation; increase productionJack and Jill both obey the two-period Fisher model of consumption. Jack earns $200 in the first period and $200 in the second period. Jill earns nothing in the first period and $410 in the second period. Both of them can borrow or lend at the interest rate r. a. You observe both Jack and Jill consuming $200 in the first period and $200 in the second period. What is the interest rate r? b. Suppose the interest rate increases. What will happen to Jack’s consumption in the first period? Is Jack better off or worse off than before the interest rate rise? c. What will happen to Jill’s consumption in the first period when the interest rate increases? Is Jill better off or worse off than before the interest rate increase?
