We then obtainunexpectedreturn on assets, marketing intensity, and R&D intensity by subtracting the expected values from the actual values. Then, we define MYO, which represents myopic management, as an indicator variable thatequals one if a firm has unexpected positive ROA and unexpected negative M...
