Firm growth. This concept has interested researchers for generations. Economists have sought to predict and measure firm growth using a host of different variables, while strategic management scholars depict growth as the result of clever analyses and rational resource exploitation. Entrepreneurship scholars - ever engrossed by successful start-ups - have pondered why growth sometimes comes fast and sometimes never at all, while the field of business history has given countless examples of growing firms in a range of different settings. Yet despite research across fields, our knowledge of how growth in a firm actually comes about is limited and we still know little about the process.
