| contents | For the Ramsey model of economic growth, which describes the optimal allocation of consumption and saving over time, we assume the population dynamics to follow the Allee effect. The so-called Allee threshold separates two regimes from each other. If starting below the threshold, the population decreases to zero. Above this threshold, it gradually saturates. We show that the corresponding consumption per capita stabilizes at two different levels accordingly. As for our main result, the consumption per capita performs in the long run better if the population becomes extinct, rather then it advances the saturation level. This is in line with our previous results on the capital per capita for the underlying Solow-Swan model of economic growth with the Allee effect. However, the comparison of consumption-to-capital ratios at the both steady states crucially depends on the curvature of the production function. |
