The decision process of an investor who must screen information of varying quality in a stock market with heterogeneous investors leads to new dimensions to consider in the risk-return space. More volatile forecast errors make it more difficult to properly form expectations from forecasts....

I estimate a demand model for online services of financial data, from a random parameters or mixed logit model, using a sample with searches at Bloomberg Terminals and at the EDGAR system. My preliminary results suggest that the substitution investors make of financial information providers, are...

Can prices convey information about the fundamental value of an asset? This paper considers this problem in relation to the dynamic properties of the fundamental (whether it is constant or time-varying) and the structure of information available to agents. Risk-averse traders receive two...

This study sheds new light on the question of whether or not sentiment surveys, and the expectations derived from them, are relevant to forecasting economic growth and stock returns, and whether they contain information that is orthogonal to macroeconomic and financial data. I examine 16...

Periods of technological revolution are usually associated with overvaluation of and overinvestment by innovating firms. This paper develops a model that explains this behavior in a frictionless rational setting. When fully rational innovating firms face uncertainty about the returns to scale of...

Why are stock prices much more volatile than the underlying dividends? The excess volatility of prices can in principle be attributed to two different causes: time-varying discount rates for expected future dividends, arising from variation in risk premia; or the irrational exuberance of...

The paper shows that the post earnings announcement drift is stronger for conglomerates, despite conglomerates being larger, more liquid, and more actively researched by investors. We attribute this finding to slower information processing about complex firms and show that the post earnings...

In this paper we present a new model of how information travels within financial markets and present empirical evidence that the concept of attention driven information efficiency is more conjugate with market data as compared to the prevailing concept of efficient markets. Augmenting our model...
