We find evidence for the beta anomaly in mutual fund performance. This anomaly is not accounted for in the standard four-factor framework, nor by the addition of a BAB factor to the benchmark model. We identify the active component of alpha (i.e., active alpha) not attributable to the passive...

We exploit heterogeneity in decreasing returns to scale parameters across funds to analyze their effects on capital allocation decisions in the mutual fund market. We find strong evidence that steeper decreasing returns to scale attenuate flow sensitivity to performance, which has a large effect...
