The authors challenge the theory that long-term investors are beneficial to publicly traded companies by asking whether or not such investors improve corporate behaviour and – importantly – whether their influence on managerial decision making improves returns to shareholders of the firm. The researchers based their paper on an average of three thousand firms annually over close to 30 years.
The findings are interesting and show they long-term investors restrain corporate misbehaviour and strengthen internal governance. The presence of long-term investors also leads to a decrease in various types of investment activity as well as external financing. However, they do lead to an increase in payouts to shareholders. That means shareholders earn higher returns on their investment as a result of both higher profitability and lower risk, write the authors. As they conclude, long-term investors rein in bad behaviour and boost shareholder value.
