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)....

Presentation Slides for "Overconfidence, Arbitrage, and Equilibrium Asset Pricing" This paper offers a model in which asset prices reflect both covariance risk and misperceptions of firmsapos prospects, and in which arbitrageurs trade against mispricing. In equilibrium, expected returns are...

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 analyze a competitive model in which different information signals get reflected in value at different points in time. If investors are sufficiently risk averse, we obtain an equilibrium in which all investors focus exclusively on the short-term. In addition, we show that increasing the...

Executive compensation has increased dramatically in recent times, but so has trading volume and individual investor access to financial markets. We provide a model in which some managers obfuscate financial statements in order to extract additional compensation. Owing to a lack of...

We focus on an intuitive measure of trading activity: the aggregate daily order imbalance, buy orders less sell orders, on the NYSE. Order imbalance increases following market declines and vice versa, which reveals that investors are contrarians in aggregate. Order imbalances in either...

We propose a theory of securities market under- and overreactions based on two well-known psychological biases: investor overconfidence about the precision of private information; and biased self-attribution, which causes asymmetric shifts in investors' confidence as a function of their...

The market micro-structure literature has typically focussed on single assets. Prior to this paper there has been virtually no empirical work on the common determinants of liquidity. This paper documents that quoted spreads, quoted depth and effective spreads co-move with market-wide and...

We document asymmetric announcement effects of consumer sentiment news on United States stock and stock futures markets. While a negative market effect occurs upon the release of bad sentiment news, there is no market reaction for the counterpart good news. This supports the “negativity...
