Abstract
The paper studies the dynamic output effects of public infrastructure investment in a small open economy. We develop an overlapping generations model that includes a production externality of public capital and a wealth effect on labor supply. Public capital enters the firm's production function under various technological scenarios. We show that if factors of production are gross complements and public capital is Solow neutral, which is the empirically plausible case, the long-run output multiplier falls short of its Hicks-neutral value. The way in which public capital augments factor productivity crucially affects the dynamics of private capital and net foreign assets, but yields qualitatively similar output dynamics. In contrast to conventional results obtained from hysteretic models, we find non-monotonic output dynamics of a public investment impulse in the non-hysteretic model. Schmitt-Grohe and Uribe's (2003) finding of identical impulse responses across the two model types is thus not robust to the inclusion of spillovers of public capital.
