A family business is a commercial organization in which decision-making is influenced by multiple generations of a family—related by blood or marriage—who are closely identified with the firm through leadership or ownership. Owner-manager entrepreneurial firms are not considered to be family businesses because they lack the multigenerational dimension and family influence that create the unique dynamics and relationships of family businesses.
Family business is the oldest and most common model of economic organization. The vast majority of businesses throughout the world—from corner shops to multinational publicly listed organizations with hundreds of thousands of employees—can be considered family businesses. Based on research of the Forbes 400 richest Americans, 44% of the Forbes 400 member fortunes were derived by being a member of or in association with a family business.
The economic prevalence and importance of this kind of business are often underestimated. Throughout most of the 20th century, academics and economists were intrigued by a newer, “improved” model: large publicly traded companies run in an apparently rational, bureaucratic manner by well trained “organization men.” Entrepreneurial and family firms, with their specific management models and complicated psychological processes, often fell short by comparison.
