DESCRIPTION:Cameron Peng - LSE\nWe study how the frequency of behavioral i
 nterventions affects retail investors' trading decisions. In a large-scale
  RCT over 3 months on a major fund distribution platform in China\, we ran
 domly vary the probability that a popup intervention appears when investor
 s attempt to redeem equity funds. Popups reduce redemption amounts by 9–
 12%\, but the effect is flat beyond the lowest treatment intensity—a lig
 ht\, infrequent intervention achieves nearly the same effect as a heavy on
 e. This flat dose-response holds for deterring redemptions\, while encoura
 ging fund conversion requires higher frequency. Effects are localized\, wi
 th no spillover to non-targeted assets\, and disappear once interventions 
 cease.
