The paper investigates the relation between the risk preferences of traders and the information aggregation properties of an experimental call market. We find evidence inconsistent with the prediction that market-clearing prices are closer to the full revelation of the state when traders are...

We generalize the long-run risks (LRR) model in Bansal and Yaron (2004) by incorporating the recursive smooth ambiguity aversion preferences of Klibanoff, Marinacci, and Mukerji (2005, 2009) and time-varying ambiguity. Relative to the Bansal-Yaron model, the generalized LRR model remains...

Executing a basket of co-integrated assets is an important task facing investors. Here, we show how to do this accounting for the informational advantage gained from assets within and outside the basket, as well as for the permanent price impact of market orders (MOs) from all market...

This paper reveals that in addition to fundamental factors, the 52-week high price and recent investor sentiment play an important role in analysts' target price formation. Analysts' forecasts of short-term earnings and long-term earnings growth are shown to be important explanatory variables...

Changes in average FinaMetrica monthly risk tolerance scores were evaluated during the January 2007 to May 2012 time period that spanned the global financial crisis. The research objective was to test whether fluctuations in equity returns influence average risk tolerance scores over time. A...

Can stock price movements be traced back partially to interpersonal utility effects? That is, are shareholders also chasing nonfinancial goals apart from generating profit under risk that can be ascribed neither to findings of behavioral finance nor to traditional economical theories? Inspired...

We explore the relation between limit order price clustering and price efficiency. We find that executed sell limit orders cluster more frequently on round increments than buy limit orders and that this asymmetry in clustering is consistent with the well documented asymmetry in price response to...

The portfolio separating distribution is sufficient and necessary for a preference-free optimal choice only if the solution is assumed to be constant a priori. The portfolio separating condition is generalized. The new distribution class allowing for correlation uncertainty is defined as...

The concept of model uncertainty is one of increasing importance in the field of Mathematical Finance. The main goal of this work is to explore model uncertainty in the specific area of algorithmic and high frequency trading. From a behavioural perspective, model uncertainty naturally leads to...

Superior to the variance, "swap variance (SwV)" summarizes the entire probability distribution of returns and is unbiased to distributional asymmetry. Retaining the same simplicity as mean-variance (MV) model, the efficiency of mean-swap variance (MSwV) is necessary and sufficient conditions for...
