hello,

i need your help with these questions, please?

Aggregate demand curve of an economy is given by AD : 50 - 0.2P. the long-run aggregate supply, LRAS. is 30 and the short-run aggregate supply is given by SRAS : 0.3 P (all output measures are in US$ billions and the price level is given as an index number). A negative demand shock shifts the aggregate demand curve to the left. The newAD curve is given by AD = 49 - 0.2R Find the new short-run equilibrium. Find the output gap as a percentage. What is the unemployment rate based on Okun's Law if the natural rate of unemployment is 4%? Short-run equilibrium: Price level is Output gap as a percentage is: and the output is US$ billions Unemployment rate is: Question 28 1 pts Assume a closed economy. Suppose that autonomous consumption equals $400, planned investment equals $500. govemment expenditure equals $200. net taxes equals $50. and the mpc equals 0.9. If government spending increases by $100, then the equilibrium aggregate output will change by $ Question 29 1 pts Assume a closed economy. Suppose that autonomous consumption equals $400, planned investment equals $500. government expenditure equals $200. net taxes equals $50. and the mpc equals 0.9. if taxes increase by $10, then the equilibrium aggregate output will change by $ ______. The GDP (Y) and aggregate consumption expenditure (C) in Canada during Q4-2018 and Q4- 2019 in chained (2012] dollars billion are given below and the consumption function is C = a + MPC'Y where a is autonomous consumption and MPC is the marginal propensity to consume. Q4 2018 Q4 2019 GDP (Y) 2,046 2,082 Consumption expenditure (CI 1,619 1,646 Find the marginal propensity to consume {MPC}, autonomous consumption, consumption multiplier. and the tax multiplier. The MPC is: l The autonomous consumption in chained (2012) dollars billion is: The consumption multiplier is: l l The tax multiplier is: Question 30 1 pts Assume a closed economy. Suppose that autonomous consumption equals $400, planned investment equals $500. government expenditure equals $200. net taxes equals $50. and the mpc equals 0.9. If government increases their spending by $50 and increases net taxes by 50, then equilibrium aggregate output will change by $
