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 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,...

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...
