The New Structuralism Topic 1: Structural Change Old and New National Graduate Institute For Policy Studies IDTP Fall 2012 John Page
Rediscovering Structural Change • Academic interest in structural change waned in the 1980s • Cross country regressions consigned it to the “residual” • The result for public policy was a focus on “whole economy” drivers of growth such as openness, institutions, governance, etc. • These prescriptions proved to be of little practical relevance to public policy
What’s New? • Sectors, Products and Firms • Products: Diversity and sophistication (Imbs, Wacziarg, Cadot, Hausmann, Rodrik) • Firms: The distribution of productivity across firms within industries (Hsieh, Klenow) • Why does it matter? • Linking the product structure of the economy to growth • Linking industrial structure with growth
Products:What you make matters • Economies with more sophisticated manufacturing sectors grow faster. • “Sophisticated” products embody advanced country knowledge and productivity • As the manufacturing base moves from low sophistication to higher sophistication activities, new export opportunities arise, knowledge becomes more generalized and productivity rises • More diverse economies have higher incomes. • More diverse economies are better able to take advantage of opportunities in global markets • A wide range of industrial activities provides a broad basis for the entry and exit of firms
Measuring Product Sophistication • Associate a per capita income with each product: • Weighted average of the per capita income of all countries that manufacture the product • Weights are “production intensities”: Share in domestic production divided by share in global production • Overall sophistication is the weighted average of the per capita incomes associated with each industry.

Industrial Structure and Productivity • Some new stylized facts: • TFP levels vary more across firms in the same industry in poor countries than in high income countries. • Variations are related to the size structure of industry. • But, why do inefficient firms survive? • Lack of competition • Policy distortions • Market segmentation
Implications for Public Policy • If “what you make matters” should governments attempt to influence the structure of production (industrial policy)? • If so, how? • Can public policy increase competition? • Can public policy raise firm level productivity?
