Suppose that due ot a fiscal stimulus, there is an increase in disposable incomes of $100 billion in the first round. Then, $33 billion was spent in consumption from this initial change of the disposable incomes. Following the same marginal propensity to consume, how much is the change in consumption spending in the next round from the $33 billion?
