To finance the war, the government had to increase taxes. Assume the MPC is .9 All the following problems require mathematical calculations. a) What was the effect of the increase in government expenditures on from 1941 to 1942 on AD? b) If income taxes increased by $4 billion, what happened to the increase in AD described in part (b)? c) If the government increased transfer payments by $4 billion, how would it affect the economy? d) If the government had increased income taxes by $4 billion and transfer payments by $4 billion, how would it have affected AD?
