- Consider an economy called Xanadu for which desired aggregate consumptiondepends on income, Y. and the real interest rate, r, according toCd =100+0.7Y - 200r.Xanadu's GDP is Y = 1000 and government spending on goods and services is G=180. Xanadu's desired future capital stock is given byK* = 140 - 100ucwhere luCdenotes the user-cost of capital. The price of capital is PK =2, thephysical depreciation rate is d =0.1 and the existing capital stock is K0= 50. Trapital stock between any period t and the following period t+1 evolves accordng toKt+1 = It+(1-d)Kt where It the level of investment. Assume throughout that net factor payments from abroad (NFP) is equal to zero.Suppose instead that Xanadu is a small open economy facing a world interest rate of 1%. It follows that Xanadu's current account position is equal toA) -16B) -51C) -6D) -8The long run macroeconomic performance of an economy can be reflectedfrom the changes of her major macroeconomic indicators. With appropriateinterpretations of the changes to these indicators, one can identify the inherentstructural features of an economy, and hence, identify her strengths andweaknesses. In about 250 words, write a short essay on ONE economy from the list below:i. Singapore;ii. The United Kingdom;iii. The United States.In your essay, describe the changes of major macroeconomic indicators fromthe last decade. Using them to illustrate major structural features of the choseneconomy. Based on the above, identify ONE inherent problem implied bythese structural features that might limit her macroeconomic performance inthe long run. Suggest ONE practical government policy in dealing with thisinherent problem.How do the long-run model and the short-run model ft together? What isthe purpose of each model?
- Suppose an economy produces only 2 products that will also be used for directconsumption, as per the article at the end of the exam: chicken wings and donuts. Inthe second quarter of 2021 (the base period), 180,000 pounds of chicken wings wereproduced, at a value of $3.50 per pound, while in the second quarter of 2022,production of chicken wings increased to 200,000 pounds, at a value of $3.75 perpound. In the second quarter of 2021 (the base period), 85,000 donuts were producedat a value of $0.85 per donut, while in the second quarter of 2022, donut productionincreased to 100,000 donuts, each at a value of $0.95 per donut. The population inthis economy is 1000 individuals in 2022, while the number of hours worked in 2022is 5000. Also, the quantities that were produced in 2021 represent the quantities thatwere purchased by the typical household, meaning that everything that was producedwas sold.d. Solve for the amount of labor productivity in the second quarter of 2022.e. Solve for the…The U.S. economy is initially in short-run macro-equilibrium. Assume that, in the face of Covid-19, firms’ costs increase as they must comply with safety regulations to keep their employees safe at work. As a result, we observe the following in our economy: Question 31 options: a) Both the price level and real GDP decrease b) The price level increases and real GDP falls c) The price level falls and real GDP increases d) Both the price level and real GDP increase.II. Consider the following IS-LM model:? = 200 + 0.25??? = 150 + 0.25? − 1,000?? = 250? = 200(?/?)? = 2? − 8,000??/? = 1,600a. Derive the IS relation. (Hint: You want an equation with ? on the left side and everythingelse on the right.)b. Derive the LM relation. (Hint: It will be convenient for later use to rewrite this equationwith ? on the left side and everything else on the right.)c. Solve for equilibrium real output. (Hint: Substitute the expression for the interest rategiven by the LM equation into the IS equation and solve for output.)d. Solve for the equilibrium interest rate.

In the absence of a change in aggregate demand, what effect does negative economic growth have on the price level over time, other things being equal? Why? 1.) Draw a new long-run aggregate supply curve that shows the effects of negative economic growth on the economy's long-run equilibrium. Label your line 'LRAS2.' 2.) Indicate the economy's new long-run equilibrium price and level of real GDP. Label this point 'E2.' The change in the price level over time due to negative economic growth and the subsequent shift in long-run aggregate supply is known as
