We solve an optimal growth model in continuous space, continuous and bounded time. The optimizer chooses the optimal trajectories of capital and consumption across space and time by maximizing an objective function with both space and time discounting. We extract the corresponding Pontryagin...

Endogenous time discounting is introduced in a two-period human-capital-driven growth model: subjective discount rate depends upon the level of human capital. This assumption accords strongly with the micro-level evidence. In the model an individual optimizes consumption over two periods. Low...
