The study of corporate entrepreneurship (CE) has principally used accounting measures to gauge a firm's CE activities, even though it has increasingly been recognized in entrepreneurial research that more appropriate, theory-based measures are required to provide an accurate picture of a firm's CE performance. This study links corporate entrepreneurship to financial theory by advancing additional value creation (AVC) as a better measure of performance for corporate entrepreneurship activities and based on the output of the firm, rather than the usual accounting measures that are input based.
