Banks produce short-term debt for transactions and storing value. The value of this debt must not vary over time so agents can easily trade it at par like money. To produce money-like safe liquidity, banks keep detailed information about their loans secret, reducing liquidity if needed to prevent agents from producing costly private information about the banks' loans. Capital markets involve information revelation, so they produce risky liquidity. The trade-off between less safe liquidity and more risky liquidity determines which firms choose to fund projects through banks and which ones through capital markets. (JEL D92, E51, G21, G31, G32)

Short-term debt that can serve as a medium of exchange is designed to be information insensitive. No one should be tempted to acquire private information to gain an informational advantage in trading that could destabilize the value of the debt. Short-term debt minimizes the incentive to acquire information among all securities of equal value backed by the same underlying asset. These features align with observed practice in money markets (markets for short-term debt). They are also consistent with financial crises occurring periodically. In the information view adopted here, financial crisis can occur when the collateral backing the short-term debt is thought to have lost enough value to raise doubts among the traders that some may acquire private information. The purpose of this paper is to review some of the burgeoning empirical literature that bears on the information view sketched above. We focus on evidence related to three key implications of information insensitive debt: (i) adjustments to external shocks will occur along non-price dimensions (less debt issued, higher haircuts, added collateral, etc);(ii) in a crisis some of the short-term debt turns information sensitive; (iii) money markets feature low transparency as well as purposeful opacity.

Two ex ante identically informed agents play a double auction over the division of a trading surplus with endogenous information and common values. This paper shows that if information acquisition is not observable, three types of inefficiencies can arise. If the information cost is in an intermediate range, no pure strategy equilibrium with trade exists although the agents maintain symmetric information. If the information cost is low, any trading equilibrium exhibits costly information acquisition. If the agents face asymmetric information cost the Akerlof's lemons problem arises as a self-fulfilling equilibrium and only partial trade occurs.Journal of Economic Literature Classification Numbers: C78, D82, D83

We investigate potential mechanisms through which market-wide sentiment affects firms’ innovation activities. We provide evidence for the financing channel by showing that financially constrained firms are more likely to issue equity and invest more in research and development (R&D) than financially unconstrained firms at high market sentiment. Using time-varying manager sentiment measures, we find suggestive evidence for a sentiment spillover channel whereby market sentiment affects R&D investments through influencing manager sentiment. Furthermore, better patent portfolios are produced from R&D investments stimulated by high market sentiment. Market sentiment has a stronger impact on R&D than the capital expenditures of financially constrained firms.
