Structural Change and Productivity Growth

1 Structural Change and Productivity Growth --in Latin America, Asia, and Turkey Dani Rodrik Merih Celasun Memorial Lecture December 2010

2 Structuralism is back Not in the sense of distrust of markets or underestimation of the role of incentives But greater appreciation of the role that economic structure plays in facilitating and constraining economic development As evidenced by work on: Inter-sectoral and inter-firm gaps in productivity dualism The export-diversification challenge Innovation as self-discovery rather than R&D Structural change as engine of development Developing economies are not just radially-shrunk versions of advanced economies

7 The Latin American paradox Productivity decomposition in Latin America across different periods (annual growth rates) Sectoral productivity growth Structural change Based on data from Carmen Pages, ed., The Age of Productivity, IDB, 2010.

8 Implications Post-1990 growth constrained by adverse structural change growth reducing structural change Consequence of economic liberalization: positive within effects, negative overall effects? Empirical work on productivity consequences of trade liberalization within manufacturing What happens if displaced labor ends up in sectors with even lower productivity Informality, traditional services, etc.

10 Questions Is this something due to post-1990 global conjuncture? How does Asia compare? Where does Turkey stand in comparison to Latin America and Asia? How can we explain these patterns?

22 Some intermediate conclusions Structural change in LAC contributed negatively (unweighted) or very little (weighted) to labor productivity growth compared to what happened in ASIA These economies are supposed to have become more open : yet in all cases the employment share of tradables (the sectors experiencing the most rapid productivity growth) has been shrinking. Some of this is normal, and associated with increase in incomes But also signs that some of it is pre-mature Turkey looks decidedly more Asian in terms of the contribution of structural change to overall productivity growth

23 Explaining differences across countries Richer countries may have less room for productivityenhancing structural change Labor market rigidities may prevent expansion of more productive sectors Trade/industrial/currency policies may: play a role in encouraging/discouraging new tradable activities expose tradables to import competition too early and excessively Comparative advantage may encourage specialization in primary products instead of manufacturing with limited potential to absorb labor

29 Concluding comments Structural transformation is the key to economic development Structural transformation is not an automatic process We need to avoid both the dirigiste and the market fundamentalist traps pragmatism rather than preconceived ideologies strategic collaboration between government and the private sector Ingredients: Institutionalized dialogues, carrots, and sticks
