Abstract
This study examines the priceโdiscovery function and information efficiency of a fast growing volatility futures market: the Chicago Board of Option Exchange VIX futures market. A linear EngleโGranger cointegration test with an error correction mechanism (ECM) shows that during the full sample period, VIX futures prices lead spot VIX index, which implies that the VIX futures market has some priceโdiscovery function. But a modified Baek and Brock nonlinear Granger test detects biโdirectional causality between VIX and VIX futures prices, suggesting that both spot and futures prices react simultaneously to new information. Quarterโbyโquarter investigations show that, on average, the estimated parameters are not significantly different from zero, thus providing further evidence supporting information efficiency in the VIX futures market. ยฉ 2011 Wiley Periodicals, Inc.

## Abstract In this study we empirically study the variance term structure using volatility index (VIX) futures market. We first derive a new pricing framework for VIX futures, which is convenient to study variance term structure dynamics. We construct five models and use Kalman filter and maximum
## Abstract The paper conducts a regression analysis utilizing both futures and cash market prices and net orderflow to determine where price discovery takes place as well as the forces at play that influence the location. Specifically, given the strong theoretical linkage between the U.S. Treasury
## Abstract This paper analyzes 31 months of data on 137 singleโstock futures (SSFs) traded on OneChicago. The results indicate that on the days they trade, SSFs contribute approximately 24% of the price discovery for underlying stocks. Information revelation in the SSFs market decreases with the r
