Economy-Wide Impacts of Industry Policy

Published 26 Sep 2012
Page updated 26 Sep 2012

Author: Anita King


The economy-wide effects of an economic development or industry policy are often ignored when developing or evaluating such a policy. However, these effects may be important for national welfare and can be estimated using CGE modelling. This paper explains the basics of CGE modelling in general and for the two models used in this paper. It then applies CGE modelling to four industry policy scenarios for the New Zealand economy to illustrate how it can be used and the range of results (including counter-intuitive results) that such models can provide. The scenarios span a range of topics: the effect of a 10% increase in demand for exports; comparing the effect of a 10% productivity improvement in large but low value-added sectors to the same improvement in small but high value-added sectors; a 15% R&D tax credit; and a 10% improvement in international freight productivity.
