In this paper, we investigate the real effects of information transparency in crowdfunding markets. Our analysis shows that the crowdfunding market features an under‐implementation inefficiency, driven by two types of uncertainty that consumers face: fundamental uncertainty about the entrepreneur's implementation cost, and strategic uncertainty due to potential coordination failures among consumers. We find that when both fundamental and strategic uncertainties are present, eliminating the fundamental uncertainty alone by revealing the implementation cost does not necessarily improve efficiency. Surprisingly, from an ex ante perspective, greater transparency makes the coordination among crowdfunding consumers less efficient, which makes the under‐implementation problem even worse and thus impairs efficiency. Our findings send a message of caution against promoting greater transparency in the crowdfunding market.

ABSTRACT We use proprietary data on intraday transactions at a futures brokerage to analyze how implied leverage influences trading performance. Across all investors, leverage is negatively related to performance, due partly to increased trading costs and partly to forced liquidations resulting from margin calls. Defining skill out‐of‐sample, we find that relative performance differentials across unskilled and skilled investors persist. Unskilled investors' leverage amplifies losses from lottery preferences and the disposition effect. Leverage stimulates liquidity provision by skilled investors, and enhances returns. Although regulatory increases in required margins decrease skilled investors' returns, they enhance overall returns, and attenuate return volatility.
