We design an experiment to study the implications of information networks for the incentive to acquire costly information, market liquidity, investors' earnings and asset price characteristics in a financial market. Social communication crowds out information production as a result of agent's temptation to free ride on the signals purchased by their neighbors. Although information exchange among traders increases trading volume, improves liquidity and enhances the ability of asset prices to reflect the available information in the market, it fails to improve price informativeness. Net earnings and social welfare are higher with information sharing due to reduced acquisition of costly signals.
