| Abstract: | First, the authors model how survival probabilities depend upon historical returns, fund age and aggregate economy- wide shocks, using two samples of US based 'income' and 'growth' funds. Subsequently, the authors employ a Monte Carlo study to analyze the size and shape of the look-ahead bias in performance persistence that arise when a survivorship free sample is used with standard techniques. In particular, the authors show that look-ahead bias induces a spurious U-shaped pattern in performance persistence. Finally, the authors demonstrate how a weighting procedure based upon probit regressions can be used to correct for this bias. |
