The Dynamic Effects of Fiscal Stimulus in a Two-Sector Open Economy
In 2009/10 governments around the world implemented unprecedented fiscal stimulus in order to counter the impact of the Global Financial Crisis of 2008/09. This paper analyzes the impact of fiscal stimulus using a dynamic open economy, overlapping generations model that allows for feedback effects of fiscal stimulus on private sector expenditure via changes in the tax rate and the interest rate. There are two types of goods-traded (T) and nontraded (N) goods-which differ in their capital intensities. The main qualitative result is that the dynamic output gains from fiscal stimulus depend on the productivity of the initial stimulus spending, on the speed of repayment of debt, on the sensitivities of the interest rate to government debt and of labor supply to the tax rate. Also, the overlapping generations framework allows an intergenerational welfare analysis. Among the biggest winners from stimulus are those about to retire. The biggest losers are those near the start of their working lives when the stimulus is implemented.
