Using the model for the determination of GDP that we have employed on this course, you are given the following information about the aggregate spending variables for a specific year, and all expressed in £ million. Total Consumption 600 (C) Investment 200 (1) Government spending 200 (G) Exports 300 (X) Imports 300. (IM) Autonomous consumption 100 (a) a) What is the value of GDP? () b) What is the value of the multiplier? () c) Calculating the multiplier in a different way, what would the value of the multiplier be if the marginal propensity to consume was 0.6, the income tax rate was 0.2 and the marginal propensity to import was 0.3? () d) Using the multiplier calculated in c) what would be the change in GDP if autonomous consumption rose by 100? ()
