Most marketing practitioners and scholars agree that marketing assets such as brand equity significantly contribute to a firm's financial performance. In this paper, we model brand equity as an unobservable stock that results from up to thirty years of past brand-related investment flows. Using firm-specific trademarks as investment proxies, our results show a significant long-run impact on financial performance. The dynamic profile of brand-related investments has an inverted-U shape that reaches its peak after eleven years. On average, it takes four years before brand related investments show a positive return, and investments older than nineteen years show no significant impact. For the median trademarking firm, brand equity contributes 265,000 Euro to annual profits.
