- The weighted average TT/US dollar selling rate depreciated marginally by 0.05 percent to US$1 = TT$6.7838 in August 2021 from US$1 = TT$6.7802 in October 2020.” Create a supply and demand graph with the above information.The short-run economic outcome resulting from the increase in production costs is known as——- Suppose now that the government immediately pursues an accommodative policy by increasing government purchases in response to the short-run impact of the higher oil prices. In the long run, given that the government pursues accommodative policy, the output level in the economy will equal ——- level will equal———Refer to the data in the table given below. Suppose that the present equilibrium price level and level of real GDP are 100 and $280, and that data set A represents the relevant aggregate supply schedule for the economy. (A) Price Level 100 100 100 100 Real GDP 205 230 255 280 (B) Price Level 110 100 95 90 Real GDP 230 230 230 230 (C) Price Level 110 100 95 90 Real GDP 280 255 230 205 a. What must be the current amount of real output demanded at the 100 price level? Real output demanded = $ b. If the amount of output demanded declines by $25 at the 100 price level shown in A, what will be the new equilibrium real GDP? The new equilibrium level of real GDP = $ In business cycle terminology, what would economists call this change in real GDP? (Click to select)
- Given the following circumstances, indicate whether or not the aggregate supply curve would shift and, if so, which way would it shift: The price of a barrel of oil doubles An advance in alternative energy technology significantly reduces its cost In order to maintain a relatively clean air quality, a carbon emissions tax is levied against firms with a carbon footprint As a result of fracking, the price of natural gas is significantly reduced Advances in technology increase the productivity of the American worker, on average, by 30%Assume that the long-run aggregate supply curve is vertical at Y = 3.000 while the short-run aggregate supply curve is horizontal at P=1.0, . The aggregate demand curve is Y = 2(M / P) and M = 1,500. Suppose the aggregate demand function shifts to Y = (1.5)(M / P) . What are the short- run values of P and Y? Show the change in short and long- run equilibrium graphically . Describe the short- run and long- run effects of the change in demand .Improved methods of inventory control were supposed to reduce fluctuations in inventory stocks. It is clear that these methods have helped reduce the equilibrium inventory/sales ratios in both the manufacturing and trade sectors over the past decade. Yet we find that during the 2001 recession, inventory investment accounted for more than the total decline in real GDP, the first time that had happened since 1949. Explain whether this result is due to a set of odd coincidences, or whether the improved methods of inventory control actually caused bigger fluctuations in inventory investment relative to final sales.
- The short-run quantity of output supplied by firms will exceed the natural level of output when the actual price level ———-that people expected.Assume that we have a Cobb-Douglas type aggregate production function in the form: Y=KaLb a-)Briefly explain why y''≤0 b-) Find the elasticity of substitution between K and L. What does expansion path look like?The following graph shows an increase in aggregate demand (AD) in a hypothetical country. Specifically, aggregate demand shifts to the right from AD1 to AD2, causing the quantity of output demanded to rise at all price levels. For example, at a price level of 140, output is now $400 billion, where previously it was $300 billion. 170 160 150 140 - 130 AD2 120 110 AD, 100 90 100 200 300 400 500 600 700 800 OUTPUT (Billions of dollars) The following table lists several determinants of aggregate demand. Complete the table by indicating the change in each determinant necessary to increase aggregate demand. Change Needed to Increase AD Wealth Taxes Interest rates The value of the domestic currency relative to the foreign currency PRICE LEVEL
- Which of the following would cause the Aggregate Supply curve to move from AS to AS2 in the graph below? A) A general increase in energy and labor cost for businesses. B) A general decrease in labor cost for businesses. C) An increase in productivity. D) A federal government increase in spending.An economy is described by the following: C=20+0.9Y I=120-200r. Md=250+0.2Y-400r. Ms/P=1250 Y=70 W=17.5 Lf=144 a) Find AS and AD. b) Find the equilibrium level of Y and P c) Graphically represent this economy d) Find the long-run Y of this economy. e) What is the level of government expenses G, the government needs to impose in order to lead the economy to the full employment? (Show the long-run graphically).Similar to how the quantity demanded for a good depends on its price, the quantity of money demanded depends on the cost of holding money, or the nominal interest rate (i). In addition to this, the demand for real money balances is also a function of income (Y). Using all of this information, suppose the demand for real money balances takes on the following functional form: (M/P)dd=500 + 2Y – 9i The Fisher equation relates the nominal interest rate to the real interest rate (r) and the expected rate of inflation (Eπ) when examining ex-ante (based on forecasts or 'before the event') effects. The equation ( (M/P)dd = 500 + 2Y – 9(Eπ – r)/(M/P)dd = 500 + 2Y – 9(r – Eπ) / (M/P)dd = 500 + 2Y + 9(r + Eπ) / (M/P)dd = 500 + 2Y – 9(r + Eπ) ) is equivalent to the function given for the demand for real money balances. Suppose the central bank announces that it will increase the money supply in the future, but it does not change the money supply today. Complete the following…
