Blau's 1977 book, Inequality and Heterogeneity, presents "a macro sociological theory of social structure" [6] where the foundation of his theory "is a quantitative conception of social structure in terms of the distributions of people among social positions that affect their social relations". [6]
Peter M. Blau (1918–2002) and Otis Duncan (1921–2004) were the first sociologists to isolate the concept of status attainment.

The papers utilize empirically based approach suggesting that an individual's position in the skill distribution is influenced by the decisions made reconsidering the cost and benefit of acquiring certain jobs.
Under this condition, even heterogeneous preferences can be represented by a single aggregate agent simply by summing over individual demand to market demand. However, some questions in economic theory cannot be accurately addressed without considering differences across agents, requiring a heterogeneous agent model.
