We study the joint time-series of daily liquidity in government bond and stock markets over the period 1991 to 1998. Innovations in liquidity are positively and significantly correlated across stock and bond markets. Further, order imbalances in the stock market impact bond and stock liquidity,...

We provide a model with overconfident risk neutral investors, and therefore no risk premia, in which a price-based portfolio such as HML earns positive expected returns and loads on fundamental macroeconomic variables. Furthermore, loadings on such portfolios are proxies for mispricing, and...

This paper offers a model in which asset rices reflect both covariance risk and misperceptions of firms' prospects, and in which arbitrageurs trade against mispricing. In equilibrium, expected returns are linearly related to both risk and mispricing measures (e.g., fundamental/price ratios)....

We provide a model in which irrational investors trade based upon considerations that are not inherently related to fundamentals. However, because trading activity affects market prices, and because of feedback from security prices to cash flows, the irrational trades influence underlying cash...

We propose a theory based on investor overconfidence and biased self-attribution to explain several of the securities returns patterns that seem anomalous from the perspective of efficient markets with rational investors. The theory is based on two premises derived from evidence in psychological...

We study the joint time-series of daily liquidity in government bond and stock markets over the period 1991 to 1998. Innovations in liquidity are positively and significantly correlated across stock and bond markets. Further, order imbalances in the stock market impact bond and stock liquidity,...

This paper offers a multisecurity model in which prices reflect both covariance risk and misperceptions of firms' prospects, and in which arbitrageurs trade to profit from mispricing. We derive a pricing relationship in which expected returns are linearly related to both risk and mispricing...

Given the lack of any clear evidence on the informational contributions of market intermediaries vis-agrave;-vis their clients in the extant literature, an important but unanswered question is whether intermediaries behave as passive traders or whether they actively seek and trade on information....

In this paper, we shed light on short-horizon return reversals. We show theoretically that a risk-based rationale for reversals implies a relation between returns and past order flow, whereas a reversion in beliefs of biased agents does not do so. The empirical results indicate that returns are...

Daily returns for stocks listed on the New York Exchange (NYSE) are not serially dependent. In contrast, order imbalances on the same stocks are highly persistent from day to day. These two empirical facts can be reconciled if sophisticated investors react to order imbalances within the trading...
