Technological diffusion implies a form of 'conditional convergence' as lagging countries catch up with technological leaders. We find strong evidence of technological diffusion but not full convergence; differences in total factor productivity (TFP) persist even in the long run due to differences...

While the economies of the fifteen countries that were in the European Union (EU15) in 2000 will continue to grow from now until 2040, they will not be able to match the surges in growth that will occur in South and East Asia. In 2040, the Chinese economy will reach $123 trillion, or nearly...

Global climate change poses a threat to the well-being of humans and other living things through impacts on ecosystem functioning, biodiversity, capital productivity, and human health. This paper briefly surveys recent research on the economics of climate change, including theoretical insights...

Finally we question the standard use of infinitely-lived, single-agent models, which assume, unrealistically, intergenerational altruism in determining optimal abatement policy. Their prescriptions can differ, potentially dramatically, from those needed to correct the negative climate...

This paper describes the correlations between inequality and the growth rates in cross-country data. Using non-parametric methods, we show that the growth rate is an inverted U-shaped function of net changes in inequality: Changes in inequality (in any direction) are associated with reduced...

If we have learned anything from the recent outpouring of empirical growth equations is that life is far too complex to expect unconditional' convergence among all countries and at" all times. This fact motivates two questions. First, why has it taken economists so long to learn" the same lesson...
