- An economy’s aggregate demand is specified as follows: C = 300 + 0.8Yd, Investment (Io) = 230, Taxes (T) = 120 + 0.2Y, Government final purchase = 400, Export (X) =240 and Import (M) = 400. Find the equilibrium national income? Find the value of the injections in this economy iii. How much withdrawals are when the economy is in equilibrium?An economy is currently in equilibrium. The following figures refer to elements in its national income accounts. Elements £ bilions Consumption (total) 70 Investment Government Expenditure 7 Imports 10 Exports 8 Table 2 A) What is the current equilibrium level of income? B) What is the level of injections? What is the level of withdrawals? C) If national income now rises by £12 billion, and as a result, the consumption of domestically produced goods rises to £68 billion. Calculate the marginal propensity to consume (MPC). D) What is the value of the multiplier? E) Comment on the results in part (c) and (d).Consider the following table showing national income in billions of dollars. Assume that the marginal propensity to import is 20% and the level of exports is $60 billion. Calculate the level of net exports for each level of actual income and fill in the table below. (Round your responses to the nearest whole number.) Actual National Income (Y) (Billions of $) 200 400 600 800 1000 Net Exports (X-IM) (Billions of $) Now assume that the marginal propensity to import increases to 25%. Calculate the new level of net exports for each level of actual income and fill in the table below. (Round your responses to the nearest whole number.) Actual National Income (Y) (Billions of $) 200 Net Exports (X-IM) (Billions of $) 400 600 800 1000 When we compare these two tables, we can see that for a given level of exports, the higher the marginal propensity to import, the the level of net exports will be at each level of income.
