Structural change is the main driver of economic development. And industrial policy is a crucial component in any successful structural change process. These are old truths periodically rediscovered by the economic profession. They were the bread and butter of ECLAC’s structuralist theory, which may claim some merit for having consistently defended them, even in times in which the general opinion leaned against industrial policy. In effect, not so long ago this policy was seen as a bad idea revealing a dubious grasp of economic theory. Fortunately, this view changed in recent years. Institutions like the IMF, World Bank and IDB have adopted a more pragmatic approach and now tend to favor industrial policy. This change in hearts and minds is most welcome.
Why has this change occurred? Many factors converge, among which growing empirical evidence that the “production structure matters”. A simple exercise may illustrate this point.
An Italian economist of the Renaissance — Serra, quoted by Reinert (2014) — deduced the wealth of the Italian cities from the number and type of occupations they had. In modern language, the wealth of a country depends on the diversification and sophistication of its production structure and on the capabilities that sustain such a structure. The higher the diversification and knowledge intensity of the production structure, the higher the productivity and competitiveness.
In other words, structural change and productivity change co-evolve: certain sectors and activities are more conducive to technical change, productivity growth and demand growth than others.
Nowadays, the complexity of an economy (its diversification and knowledge intensity) cannot be estimated by simply counting the number of occupations, as in Serra’s time. More sophisticated indicators are required; the graph below presents the Augmented Complexity Index suggested in Cabello et al (2013). The ACI combines data on the sophistication of the export structure (high and medium technology exports) and the sophistication of the production structure (share of the engineering industries in manufacturing value added), along with patents and expenditures in R&D.
