Ownership structure and firm performance: Some empirical evidence from Spain

The ‘managerial’ and the ‘contractual’ theories of the firm imply different causes and consequences for the relationship between ownership and performance of firms. This paper provides a test of the two conflicting theories, using ownership and performance data from a sample of Spanish family- and non-family-controlled firms. We find evidence in support of the contractual theory of the firm, according to which firms choose their ownership structure maximizing economic value, net of contractual costs.
