Question
Chapter 11, Problem 1RQ
To determine
The key assumption of basic Keynesian model and its impact on short-run economic fluctuations.
Expert Solution & Answer
Explanation of Solution
The key assumption of the basic Keynesian model or the Keynesian cross is that ‘in the short run, firms meet the demand for their products at preset prices. This would mean that firms fixed a price for some period and meet the demand at the predetermined price rather to respond every change in the demand for their product. The fact is that firms do not change their prices frequently due to the menu cost. If the firms produce to meet the demand, then changes in demand dictates the level of output in the short run.

After staying virtually flat for about a year and a half, the average lending rate of banks has started to show signs of decline in April after the Bank of Ghana reduced the monetary policy rate the month before. The Summary of Economic and Financial Data (May 2020) published by the Bank of Ghana has shown that average lending rate has finally moved out of its comfort zone to a step downward. Prior to recording 22.38 percent in April, the average lending rate has since the past 17 months (December 2018) not come below 23%.How would banks benefit when interest rates decrease?
If a firm believes that their relative price has changed, then they will increase their output, since their
product is more valuable (in relative price terms). Thus, the output of firms will be Y = Y +x (P - EP)
where alpha is the relative increase in work driven by an increase in expected price level
Thirty percent of firms can adjust their prices ex-post. If a=1, and the current price level is $200,
then draw the SRAS curve around the potential output of $10,000. Then, determine the increase
in price above expectation if 40% of firms are sticky-price firms, flexible price firms respond with
a=0.02 and Y rises by $2400.
(A Two-Period Sticky-Price Model). Consider a two-period, sticky-price economy like the one studied in lectures 11-13. Suppose that the household’s intertemporal optimality condition is of the form C2 C1 = β P1 P2 (1 + i), where C1 and C2 denote consumption in periods 1 and 2, P1 = P2 = 1 denote the price levels in periods 1 and 2, β = 0.9 denotes the subjective discount factor, and i denotes the nominal interest rate, which must satisfy the zero lower bound (ZLB). Suppose further that the full employment levels of output in periods 1 and 2 are given by Y¯ 1 = Y¯ 2 = 1, and that the economy is always at full employment in period 2 (the long run).
Part 1: Suppose the central bank sets the nominal interest rate at the level i ∗ that minimizes unemployment without overheating. Calculate i ∗ .
Part 2: Suppose that due to bad expected meteorological conditions, the full-employment level of output in period 2 is revised down to 0.8. Suppose that in response to this news, in period 1 the…

- Your Policy Brief team has modelled the effects of an investment in Research & Development (R&D) that leads to the invention of a new production method which makes more efficient use of renewable energy sources. This new production method can be disseminated throughout the economy, bringing down production costs for businesses, and enabling the economy to make more productive use of existing resources. This brings an expansion in the economy’s productive capacity. Illustrate the predicted effects of this innovation using an AD-AS diagram. Provide bullet points to explain what is happening in your diagram. As with all of your diagrams, be sure to indicate the original and new equilibrium points, and what happens to output and price level. To conclude your explanation, explain what the link between innovation and economic prosperity and wellbeing is.arrow_forwardPresident Biden recently boasted of his administration’s success in lowering the deficit of the US government. This reduction could be considered “budget austerity”. Budget austerity usually involves a reduction in federal government spending and/or the raising of taxes to keep the budget deficit under control. Assume that just as austerity was beginning that we found the economy at a level of Ye that was below full employment (Ye < YN), as we did in the first two quarters of 2022. Illustrate graphically using the simple expenditure model developed in class what austerity will mean when for the level of planned spending when we start at Ye<YN, in theory, for the level of planned spending and equilibrium output as it takes effect. Lastly, given the movement you show in planned spending, if any, does the policy of austerity make sense if your goal is use policy to achieve YN? Explain.arrow_forwardRecall the Keynesian Cross is the foundation to derive the IS curve. Suppose we have a simple closed economy. The cross of planned expenditure (PE) and the equilibrium condition (PE = Y) of this economy shows the equilibrium level of national output in the goods market. Here we assume the consumption (C) is a function of • C = 120 + 0.75(Y-T); Here the marginal propensity to consume (MPC) equals 0.75. Planned investment (I) is 200; government purchases (G) and taxes (T) are both 400. Use the conditions given, finish the following questions. (1) What is the equilibrium level of national income? Show step-by-step solution. Tip: recall the definition of planned expenditure (PE). At equilibrium, actual expenditure (Y) equals planned expenditure.

How much is the change of national income from the increase in…arrow_forward
- Based on research conducted by the Department of Economic Analysis, the government and policy advisors of an economy believe that the full employment GDP is $7500 billion, and Pe, the overall expected price level is 118. In addition, the researchers estimate that the short run aggregate supply equation is Y = Ypot + 80 (P - Pe), where Ypot is the potential level of output. In addition, the researchers estimate that the short run aggregate supply equation is Y = Ypot + 80 (P- Pe), where Ypot is the potential level of output. In 2016, the population was 400 million, and the structure of the economy was described by the following equations for household consumption behavior and taxes received: C = 100+ 0.8DI, and T = 0.25Y where all monetary values are in billions of dollars. Government spending was fixed at $1700 billion, and firm's investment behavior was fixed at $800 billion. Trading is allowed in this economy and in 2016, trading occurred such that the trade account was balanced.…arrow_forwardDo supporters of the Keynesian perspective generally prescribe a hands-off approach to managing the economy, or support an active role for the government in managing the economy? Why? (12.4)arrow_forwardFor the linear IS-LM model, the goods market and the money market are in equilibrium when. Suppose that the economy is characterized by the following equations: (Y;r) = ( 1200 ; 6), Y-C-IG=0, C-Co-c(Y-T)=0,I-Io+hr=0, and kY-ur-M^s=0, which are satisfied for Co=60, lo=150, G=250, T=200, M^s=60, with the parameters c=0.8, k=0.1, h=10, and u=10. How are the equilibrium and affected, a) if "h" (the sensivity of the demand for investment to the interest rate) decreases to 5? b) if "u" (the sensitivity of the demand for real money balances to the interest rate) decreases to 5?arrow_forward
- In the Keynesian macroeconomic model, the equation for the savings function is given as: S = -420 + 1/4Y. Based on this information, which of the following statements is correct? (1) The marginal propensity to consume is 1/4;(2) The marginal propensity to save is -420; (3) At an income level of R1 000, the value of savings is 250;(4) At an income level of R1 000, the level of savings is -170.arrow_forwardA recessionary gap exists when the macro economy is in equilibrium at less than the potential output of the the economy because aggregate demand is insufficient to fully employ all of society' s resources. In other words, the equilibrium (AD = AS) occurs to the left of the vertical long-run supply curve. At this point, potential output is reached ( full employment) and if any unemployment occurs, then it is due to structural or frictional; that is, the economy is at its natural rate of employment. True Falsearrow_forward10 . In the “complete Keynesian model”, the investment functions was I = I0 - f(i). An analyst now proposes the following investment function: I = I0 - f(i) + qY, where “q” is a parameter and Y is national income = GDP. Provide two different arguments, i.e. explanations as to why this investment function makes sense. The focus is on the new term, qY (q times Y), in the function.arrow_forward
