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...

We compute the growth effects of adopting a revenue-neutral flat tax for both a human capital--based endogenous growth model and a standard neoclassical growth model. Long-run growth effects are decomposed into the parts attributable to the flattening of the marginal tax schedule, the full...

We examine the effects of tax reform in an endogenous growth with two types of useful public expenditures. The optimal fiscal policy shifts the tax base to private consumption and generally requires a change in the size of government. If a tax reform holds the size of government fixed to satisfy...

This paper examines the economic effects of tax reform in an endogenous growth model that allows for two types of useful public expenditures; one type contributes to human capital information while the other provides direct utility to households. We show that the optimal fiscal policy calls for...

This paper considers a time varying parameter extension of the Ruge-Murcia (2003, 2004) model to explore whether some of the variation in parameter estimates seen in the literature could arise from this source. A time varying value for the unemployment volatility parameter can be motivated...
