Costly arbitrage and asset prices: evidence from closed-end funds

If arbitrage is costly and noise traders are active, asset prices may deviate from fundamental values for long periods of time. We use a sample of 158 closed-end funds to show that noise-trader sentiment, as proxied by retail-investor flows, leads to fluctuations in the discount. Nevertheless, we reject the hypothesis that noise-trader risk is the cause of the long-run discount. Instead we find that funds which are more difficult to arbitrage have larger discounts, due to: (i) the censoring of the discount by the arbitrage bounds, and (ii) the freedom of managers to increase charges when arbitrage is costly
