We survey 79 private equity (PE) investors with combined assets under management of more than $750 billion about their practices in firm valuation, capital structure, governance, and value creation. Investors rely primarily on internal rates of return and multiples to evaluate investments. Their limited partners focus more on absolute performance as opposed to risk-adjusted returns. Capital structure choice is based equally on optimal trade-off and market timing considerations. PE investors anticipate adding value to portfolio companies, with a greater focus on increasing growth than on reducing costs. We also explore how the actions that PE managers say they take group into specific firm strategies and how those strategies are related to firm founder characteristics.

We investigate how personal characteristics affect people's desire to collaborate and whether this attraction enhances or detracts from performance in venture capital. We find that venture capitalists who share the same ethnic, educational, or career background are more likely to syndicate with each other. This homophily reduces the probability of investment success, and the detrimental effect is most prominent for early-stage investments. A variety of tests show that the cost of affinity is most likely attributable to poor decision-making by high-affinity syndicates after the investment is made. These results suggest that “birds-of-a-feather-flock-together” effects in collaboration can be costly.
