In December 2017, both the CBOE and the CME introduced futures contracts on bitcoin. We investigate to what extent they provide useful information for the price discovery of bitcoin.

We estimate quantile autoregression (QAR) models to analyze variations in the autoregressive coefficients of 55 international stock index returns and demonstrate that it is important to allow the autoregressive parameters to vary with quantiles. The empirical results identify distinctively...
