The graph reveals a strong negative correlation between inequality (measured by the share in total GDP of the richest 10% as compared to the poorest 10%) and the degree of technological intensity of the production structure (measured by value added per capita in the engineering industries). In general, when knowledge-intensive activities in the economy are few, and employment concentrates in low-productivity jobs, a large share of total labor is allocated in low-paid jobs or in the informal sector. This heightens inequality. Inversely, a diversified economy with many knowledge-intensive sectors implies faster learning and the accumulation of complementary capabilities. A denser, more integrated production structure leads to more high-productivity jobs and faster productivity growth. This in turn fosters economic growth, employment and income distribution.
