"Essays On Labor Dynamics And Industrial Growth: Supply Chains, Innovation And Informality"

This PhD thesis examined why manufacturing has struggled to become a strong source of growth and quality job creation in many developing countries. It focused on three closely connected issues: widespread informal work, weak linkages between firms, and insecure forms of employment. Using evidence from India and Sub-Saharan Africa, the research showed that although informal businesses employ many workers, they tend to be much less productive and can slow down overall industrial progress. The thesis also found that informal firms benefit from working with formal firms only when their workers have sufficient skills to learn and apply new knowledge. In addition, the research demonstrated that heavy reliance on short-term or contract workers can reduce innovation, as firms lose experience, commitment, and know-how over time. Overall, the thesis highlighted that industrial growth depends not only on expanding production, but also on improving skills, strengthening firm relationships, and creating more stable and supportive labor market institutions.
