Formal economic models of entrepreneurship have two characteristics: they model entrepreneurship as an allocation of resources, and they identify common factors affecting this allocation. These common factors are represented as parameters of optimization models, and they are evaluated at the market level. We argue that although these models are useful, they are incomplete because certain aspects of entrepreneurial behavior, such as judgment, alertness, or innovativeness, cannot be easily transformed into allocative problems. Moreover, entrepreneurial acts involve idiosyncratic elements, which limit the applicability of the market-level analysis to individual cases. Thus, the traditional economic methods have to be complemented by approaches highlighting the role of individual and historical specificity. The study of entrepreneurship, therefore, requires a synthesis of both general theory and historicist approaches, as envisioned a century ago by Frank Knight.
