The predominant approaches to comparative corporate governance view legal transfers dichotomously, seeing corporate governance systems as either converging or diverging as a result of legal reform. Drawing on legal studies, this paper proposes an alternative model using the metaphor of the staircase to conceptualize how legal transplants can meet different evaluation criteria before being considered ‘successful’. The model is empirically illustrated by the introduction of the Swedish Corporate Governance Code. It is found that different corporate governance rules when transplanted could be said to meet evaluation criteria more or less strictly. This finding has implications for our empirical and theoretical understanding of how corporate governance systems converge.
