"The oil price run - up of 2007 - 08 was caused by strong demand confronting stagnating world production. Although the causes were different, the consequences for the economy appear to have been very similar to those observed in earlier episodes, with significant effects om overall consumption spending and purchases of domestic automobiles in particular. The experience of 2007 - 08 should thus be added to this list of recessions to which oil prices appear to have made a material contribution". Oil price shocks have an evident impact on the short run aggregate supply curve. With the help of a graph demonstrate how rising oil prices affect the SRAS and explain what other factors can cause this shift.
When income is zero within the Keynesian cross model planned expenditure will be greater than zero and the intercept of the consumption function will hence not be zero either. The reason for this feature of the model is that either: The Marginal Propensity to Save (MPS) is greater than 0.5 The Marginal Propensity to Consume (MPC) is greater than 0.5 Autonomous consumer expenditure depends only on the level of national income Autonomous consumer expenditure does not depend on the level of national incomeOnly one answer can be correct. Please pick one and explain your reasoning.

• Assuming that there is no government spending or trade, an economy's GDP is the sum of domestic consumption C and investment I, ie. Y = C+ 1 of • Assume that I is unaffected by GDP • Assume the consumption function is C = co + cY • In any equilibrium aggregate demand, AD must be equal to Y, GDP. Given this model, which of the following statements is correct? Select one or more: O a. The aggregate demand equation is given by AD = Co + CY + I %3D O b. C is equal to autonomous consumption. O c. if c is a number between 0 and 1, and I+Co >0 then the aggregate demand equation is a straight line that must intersect the 45 degree line at some point. O d. In a demand-driven economy the AD curve is a vertical line Oe. In a demand-driven economy demand is equal to supply in equilibrium Of. In a supply-driven economy demand is equal to supply in equilibrium g. In a demand-driven economy, supply creates its own demand Oh.

Question #4. Individual income taxes directly affect personal disposable incomes which in turn affect the domestic demand for goods and services. Production costs depend substantially on oil prices. Market expectations are: (1) income taxes in the U.S. will decline and (2) oil prices will remain relatively unchanged. Using market expectations, what do you expect the U.S. output and prices next year? Assume we are moving from the old equilibrium to a new equilibrium. Please state clearly your assumptions and include a graph to support your answer.
We again assume asimple closed economy with GDP of 100 and:c0(autonomous consumption) = 20c1 (marginal propensity to consume) = 0.6I (investment) = 20.a) Now assume that c0falls by 5 (i.e. 5% of GDP), i.e. for any given level of output,consumption will fall by 5. Show the implied fall in the AD function in yourdiagram and show that output will fall by more than 5.b) Show that the multiplier is equal to 2.5, and hence that, in the new equilibrium,output will have fallen by 12.5 (i.e. by 12.5%)c) How big would the impact be if, say, c1 = 0.4 or c1 = 0.8? Explain the difference.
