A Reconsideration of the Theory of Non-Linear Scale Effects
by Richard G Lipsey
Published 20 March 2018
The main thrust of this Element is a critical assessment of the theory and evidence concerning the sources of scale effects. It is argued that the analysis of static scale effects is important because scale effects are embedding in our world, and new technologies associated with an evolving economy often allow their exploitation when they cannot be exploited in less technically advanced and smaller economies. So, although static equilibrium theory is not a good vehicle for studying economic growth, showing how scale effects operate when output varies with given technology helps us to understand the scale effects that occur when output rises as a result of economic growth, even though that is typically driven by technological change.
Dismissing industrial policy because 'governments cannot pick winners' is counter-productive. This Element studying selected major innovations illustrates the fact that virtually all major new technologies have been developed by a synergetic cooperation between the public and the private sectors, each doing what it can do best. By examining how R&D is financed, rather than where it takes place, the authors show that the role of the public sector is much more pronounced than is often thought. The nature of the cooperation − who does what − varies with the nature of each innovation so that simple, one-size-fits-all, rules about what each sector should do are suspect. These results are particularly important because they challenge the scepticism in the United states and elsewhere about the importance of industrial policy, a scepticism that threatens to undermine the long-term, and necessary cooperation, between the public and private sectors in promoting growth-inducing innovations.
