The current value Hamiltonian in an aggregate optimal growth problem with heterogeneous
capital stocks including exhaustible, renewable and environmental stocks is the NNP …

This paper first analyzes a model of economic growth with stock pollution allowing smooth
substitution between emissions and reproducible capital. When emissions are optimally …

The materials balance principle points to the crucial role of material inputs in generating
residuals in production processes. Pollution modelling must be of a multi-output nature. The …

The key feature when modelling joint production of intended outputs and unintended
residuals is that the latter stem from the use of material inputs. A multi-equation model …

Despite their great popularity, all the conventional Divisia productivity indexes ignore
undesirable outputs. The purpose of this study is to fill in this gap by proposing a primal …

The materials balance principle points to the crucial role of material inputs in generating
residuals in production processes. Pollution modelling must be of a multi-output nature. The …

The capital theoretic approach to the environment as a wastable stock, a stock with a flow of
abatement services, is explored in a simple Ricardo-like model involving wheat production …

Firm innovativeness refers to an organization's overall capability to engage in new ideas
and concepts that may lead to the actual implementation or introduction of product or …

The current value Hamiltonian in an aggregate optimal growth problem with heterogeneous
capital stocks including exhaustible, renewable and environmental stocks is the NNP …

The generation of unintended residuals in the production of intended outputs is the key
factor behind our serious problems with pollution. The way this joint production is modelled …
