According to New Growth Theory one cannot rely on the convergence mechanisms inherent in traditional neoclassical constant returns to scale models. Convergence as well as divergence is possible, in general, depending on the assumptions about technology, factor mobility and ease of knowledge...

We develop an overlapping generations endogenous growth model with stocks of produced capital, human capital, a non-renewable resource, and irreversibly accumulated greenhouse gases in deterministic and stochastic versions. The model allows for analyzing different elasticities of substitution....
