Total factor productivity captures how effectively an economy turns inputs like labor and capital into output, reflecting technology, know-how, and the organization of resources. When we compare countries, differences in TFP often explain much of the gap in income, because two nations with similar amounts of capital and labor can produce very different levels of output due to how efficiently they use those inputs, how advanced their technology is, and how favorable their institutions are for innovation and adoption of new ideas. Policies that are typically thought to boost TFP include establishing strong, predictable rules of law and high-quality institutions to protect property rights and reduce corruption; investing in education and human capital to raise the skills of the workforce; funding research and development and supporting innovation; and maintaining openness to trade and competition, which helps ideas and technology diffuse more widely. So, TFP is not about having more capital or abundant natural resources alone; it’s about improving efficiency, technology, and the environment in which firms operate.
