Maurice Potron is an important precursor of the study of linear models of production and, in particular, of input-output analysis. We show that, contrary to Abraham-Frois and Lendjel's interpretation which we consider as unfaithful to Potron's model, there is a clear connection between his...

In effective rates of sectoral productivity change, some of the inputs are treated as produced. Here, this is extended to cover all the inputs. All the sectoral rates of productivity growth based on a static input-output (IO) framework are shown to be equal to the corresponding rates of decrease...

This paper discusses the problem of exhaustible resources in a dynamic input-output model with 'classical' features. Both the quantity side and the price and distribution side are discussed. The argument is developed using the simplifying assump- tions that there is no technical progress and...

Natural resource accounts (NRA) can provide an effective tool for linking information about the environment and the economy. However, because NRA are quite new, their contribution to policy-making is not yet well established. This paper provides an example of how NRA can be used for policy...

In this paper, the input-output model is extended with assets. It allows us to examine the various assets that are held and used in production. The requirements of assets that must be held by each sector can thus be specified. Extending the input-output model with assets provides a better...

Increased spatial dependency of economic activities, as well as spatial differentiation of production and consumption, has implications for environmental policy. One of the issues that has gained importance is the responsibility for the emissions from products that cross national boundaries...
