Liquidity and Investment in General Equilibrium

By:	Nicolas Caramp; Julian Kozlowski; Keisuke Teeple
Abstract:	This paper studies the implications of trading frictions in financial markets for firms' investment and dividend choices and their aggregate consequences. When equity shares trade in frictional asset markets, the firm's problem is time-inconsistent, and it is as if it faces quasi-hyperbolic discounting. The transmission of trading frictions to the real economy crucially depends on the firms' ability to commit. In a calibrated economy without commitment, larger trading frictions imply lower capital and production. In contrast, if firms can commit, trading frictions affect asset prices but have no effect on capital and production. Our findings rationalize several empirical regularities on liquidity and investment.

Abstract:	The efficient market hypothesis predicts that asset prices reflect all available information. A seminal experiment reported that contingent claim markets could yield market outcomes consistent with information aggregation when traders hold heterogeneous state-contingent values. However, a recent experiment found the rational expectation model outperformed the prior information and maxi-min models in contingent claim markets when traders hold homogeneous values despite the no trade equilibrium in that setting. But that same study failed to replicate the original result calling into question when, if ever, prices reliably reflect the aggregate information of traders with heterogeneous values. In this paper, we show contingent claim markets can robustly yield prices consistent with the efficient market hypothesis when traders hold heterogeneous values in certain circumstances. The key distinction between our environment and that of the previous studies is that we consider trader values that are correlated and not too dissimilar.
