1. To calculate the GDP recall that the formula is
Y = C + I + G + X - M
In this case we have values for all components except I (gross investment) given in the table. To calculate gross investment use the formula
Gross Investment - Depreciation = Net Investment
Gross Investment = Net Investment + Depreciation = 1.4 + 0.2 = 1.6
Plug all variables into the GDP equation:
Y = 3 + 1.6 + 2 + 0.5 - 0.3 = 6.8
Thus the GDP is 6.8 trillion.
2. The unemployment rate is defined to be
Unemployment Rate = (Total Unemployed / Total Labor ...
An increase in the marginal propensity is noted.
