The per capita real GDP growth rate has been remarkably stable for many decades in most developed countries. To explain the balanced growth, however, existing endogenous growth theories typically need to assume a knife-edge degree of externality, which is not yet confirmed by micro-level...

When a continuum of technologies is introduced to the model of Grossman and Helpman (1991), both continuous and discrete technological progress may occur as a result of technology choices by private firms. A good is created through R&D based on one of a continuum of technologies that differ in...

We prove a generalized, multi-factor version of the Uzawa steady-state growth theorem. The theorem implies that neoclassical growth models need at least three factors of production to be consistent with empirical evidence on both the capital-labor elasticity of substitution and the existence of...

We prove a generalized, multi-factor version of the Uzawa steady-state growth theorem. In the two-factor case, the theorem implies that a neoclassical growth model cannot be simultaneously consistent with empirical evidence on both capital-augmenting technical change and the elasticity of...

This paper examines the implications of the mutual causality between environmental quality and economic growth. While economic growth deteriorates the environment through increasing amounts of pollution, the deteriorated environment in turn limits the possibility of further economic growth. In a...

This paper examines the effect of growth-enhancing policies in an R&D-based endogenous growth model when the government does not have the ability to raise taxes to finance the required expenses. We show that the government can increase the economic growth rate by debt-financed R&D subsidies...
