Theoretical and empirical studies of life history aim to account for resource allocation to the different components of fitness: survival, growth, and reproduction.

Structural change involves a broad set of trends: (i) sectoral reallocations, (ii) rich movements of productive activities between home and market, and (iii) an increase in the scale of productive units. After extending these facts, we develop a model to explain them within a unified framework. The crucial distinction between manufacturing, services, and home production is the scale of the prod...
