Suppose in a simple economy with no foreign sector, the MPC is equal to 0.8. If the government increased government spending by 30million,anditsimultaneouslyraisedtaxesby30 million, how much will be the change in output (∆Y)?
Output will increase by $30 million
This is the case of a balanced budget multiplier. If an increase in government spending is matched by an equal increase in taxes, the increase in output will be equal to the increase in G.
