In this note, we use a technique analogous to Xie's method (1994) to solve analytically the Lucas model with externality in a specific parametric case. In particular, we characterize the shape of imbalance effects in this model. Our results are entirely consistent with the findings of the...

This paper analyzes the conditions under which, within a two-sector endogenous growth model with human and physical capital accumulation but without R&D-driven disembodied technological progress, we can observe an ambiguous effect of population growth on economic growth, as empirical evidence...
