In an open economy, the marginal propensity to consume c is 0.9, and the tax rate is 1/3. If the budget deficit increased by 15 mil. € determine:
a) the change in the level of investments that could have led to this increase in the budget deficit;
b) assuming that the increase in budget deficit is due only to the increase in government spending, determine the change in government spending (∆G) that could have led to this effect.
Consider a closed economy for which the following initial data are known: c = 0.7, t = 0.15; the initial level of GDP is 3400 bil. $, the private consumption is 2000 bil. $, G = 500 bil. $, I = 900 bil. $ and autonomous taxes, transfers and subsidies are 0.
