The concept of parenting advantage offers a clear framework and guiding principle for corporate-level decision-making, including corporate portfolio management and corporate organization. Matthias Krühler fundamentally investigates the ability and explanatory power of the parenting advantage concept in order to effectively manage business portfolios. His theoretical, conceptual, and empirical research addresses identified shortages and expands the scientific application of the 1994 introduced concept. The author provides a number of valuable contributions for strategic management theory, reveals new avenues for future research on corporate strategy, and highlights normative implications for corporate management practice.
