We report the results of the first large-scale, long-term, experimental test between two crowd sourcing methods – prediction markets and prediction polls. More than 2,400 participants made forecasts on 261 events over two seasons of a geopolitical prediction tournament. Some forecasters traded...

How robust are experimental results to changes in design? And can researchers anticipate which changes matter most? We consider a specific context, a real-effort task with multiple behavioral treatments, and examine the stability along six dimensions: (i) pure replication; (ii) demographics;...

Prediction markets for future events are increasingly common and they often trade several contracts for the same event. This paper considers the distribution of a normative risk-neutral trader who, given any portfolio of contracts traded on the event, would choose not to reallocate that...

The size of the equity risk premium remains an unanswered question in the accounting and finance literature. This study proposes a new approach to reverse-engineer the equity risk premium, distinct from prior research, in that it does not rely on analysts’ forecasts to proxy for the market’s...

This paper extends the study of Herrmann and Thomas (2005) on granularity in analyst forecasts at multiples of nickels and finds that forecasts at multiples of nickels are more optimistic, and induce weaker market responses. Granularity in analyst forecasts combined with managers’ incentive to...

This paper discusses the ability of models on cheap talk, and of audit and liability regulations, to provide analytically-based assessment of credibility of management forecast disclosure in market and regulated settings. While credibility is linked to restrictive conditions in pure market...

This paper examines differences in the trading patterns of institutions. Investee firms with different levels and types of institutions are also examined. A method is developed to categorize institutions as active or inactive. Changes in the level of information, changes in the CAR response,...

Managerial behavior differs considerably when managers report quarterly profits versus losses. When they report profits, managers seek to just meet or slightly beat analyst estimates. When they report losses, managers do not attempt to meet or slightly beat analyst estimates. Instead, managers...

This paper examines cross-sectional differences in the optimistic behavior of financial analysts. Specifically, we investigate whether the predictive accuracy of past information (e.g., time-series of earnings, past returns, etc.) is associated with the magnitude of the bias in analysts'...

We investigate firms' propensity to meet analysts' forecasts of cash flows and earnings, and identify factors pertaining to market valuation, financial analysts, and firms' financial condition to explain why firms sometimes meet cash flow forecasts but miss earnings forecasts. Firms meet cash...
