The renewal of interest in macroeconomic theories of search frictions in the goods market requires a deeper understanding of the cyclical properties of the intensive margins in this market. We review the theoretical mechanisms that promote either procyclical or countercyclical movements in time...

Using cross-country data, we review the empirical evidence concerning long-term labor and total factor productivity growth. We find that the conclusions one can draw from cross-country data are surprisingly modest. Nevertheless, we confirm the crucial role for physical capital accumulation in...

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 generalizes the Nelson-Phelps catch-up model of technology diffusion. We allow for the possibility that the pattern of technology diffusion can be exponential, which would predict that nations would exhibit positive catch-up with the leader nation, or logistic, in which a country with...

Parents with higher education levels have children with higher education levels. However, is this because parental education actually changes the outcomes of children, suggesting an important spillover of education policies, or is it merely that more able individuals who have higher education...

This paper examines the channels through which country characteristics affect growth. We investigate whether "primitives," or rates of factor accumulation, are sufficient statistics for economic growth, and whether "ancillary variables," such as political instability, income distribution, and...

This paper develops a quantitative general equilibrium model to assess the growth effects of adopting a flat tax plan similar to the one proposed by Hall and Rabushka (1995). Using parameters calibrated to match the progressivity of the U.S. tax schedule and other features of the U.S. economy,...
