Although economic agents should discern signals from noise when drawing from experience, recent evidence suggests decision-making can be based on both noise and signal components. This column uses a natural experiment of IPO lotteries in India to show that randomised gains cause winning investors to increase applications to future IPOs and substantially increase portfolio trading volume in non-IPO stocks relative to lottery losers. Investors appear to draw inferences about their skill from noise.
