We use a simple endogenous growth model with productive public capital to investigate the degree to which observed fiscal policies in eight OECD countries can account for slowdowns in the growth rates of aggregate labor productivity since 1970. In model simulations, we find that none of the...

This paper develops a quantitative theoretical model for the optimal provision of public capital. We show that the ratio of public to private capital in the U.S. economy since 1925 evolves in a manner that is broadly consistent with an optimal transition path derived from a simple growth model....

This paper evaluates the efficiency implications of various fundamental tax reforms in an infinite-horizon endogenous growth model with public-sector investment in human capital. A fully optimal reform requires the government to adjust its expenditures on education, training, or R&D to take into...

This paper investigates a variety of objectives that are commonly used to motivate government fiscal action. These include, welfare maximization, stabilization and growth maximization. The policies are compared on the basis of their implications for welfare, volatility and growth. We show that...
