通过允许不可再生资源进入技术，可以放松标准内生增长模型对技术施加的尖端限制吗？为了回答这个问题，我们考察了当不可再生资源是增长引擎的必要投入时，稳定的内生增长是否与相对于可生产投入不断增加的规模回报兼容。在一个单部门最优增长模型中，我们发现稳态的存在性和稳定性与广泛的参数值相容，包括资本和/或自然资源收益递增的情况。然而，在所有情况下，人口增长被证明是公共关系稳定增长的必要条件。人均消费。因此，在这种情况下，(严格地)内生稳定增长是不可能的，即使是刀刃的情况也不可能。但半内生增长是一个有吸引力的选择，可以提供一系列丰富的长期增长决定因素。
Can the knife-edge restriction on technology imposed by standard endogenous growth models be relaxed by allowing for nonrenewable resources entering the technology? To answer this question we examine whether stable endogenous growth is compatible with increasing returns to scale with respect to producible inputs when nonrenewable resources are a necessary input into the growth engine. In a one-sector optimal growth model, we find that the existence and stability of a steady state is compatible with a wide range of parameter values, including cases with increasing returns to capital and/or the natural resource. However, in all cases, population growth turns out to be necessary for stable growth in pr. capita consumption. Thus, under these circumstances, (strictly) endogenous stable growth is not possible, not even as a knife-edge case. But semi-endogenous growth is an attractive alternative allowing a rich set of determinants of long-run growth.
