The Theory of the Growth of the Firm

Penrose fills the gap between Coase and Chandler. Coase explained why firms exist; Chandler documented how they grew; Penrose explains the mechanism — firms grow by deploying accumulated knowledge and unused resources into adjacent opportunities. Growth is not a response to market signals alone but a consequence of what the organisation has learned to do. This is the origin of the resource-based view of the firm, later developed by Wernerfelt and Barney, and the intellectual ancestor of every "capabilities" argument in strategy. For product people it reframes the question: the constraint on what you can build next is not the market but the knowledge your organisation has accumulated and can redeploy.
