This paper shows how idiosyncratic resources can be the basis of sustained profitability and persistent heterogeneity under competitive conditions: Generic inputs purchased in the market become idiosyncratic resources by investments in customization. Analytically, we show how heterogeneous firms co-exist in equilibrium. Computationally, we show that sustainable profits can emerge without monopolistic imperfections. We consider how capability heterogeneity, resource customization cost and ease of expansion interact to drive short-run and sustainable profits. Results illustrate that, in an industry evolution context, sustainable profits may represent a small part of total wealth creation, and that changes in factors shaping a sectors' evolutionary trajectory may be more important than changes in factors that determine profits' ultimate sustainability, thus calling into question the familiar emphasis on sustainable advantage.
