=8 factors in the BKT model, given by theseven FH risk factors and the return of our correlation swap (Model 2).Using GLS estimators, we estimate a negative market price of correlationrisk with respect to models 1 and 2, both with and without Shanken’s asymptoticcorrection. The point estimate for the correlation factor risk premium is highlystatistically significant, witht-statistics of−4.14 and−4.06, respectively,in each model.19In contrast, the GLS point estimates for other well-known18The EIV problem has a number of potential consequences in two-step least squares procedures. First, if standarderrors do not include information that beta coefficients are measured with error, the impliedt-statistics mightoverstate the precision of the risk premium estimates. Second, different estimators might have substantiallydifferent properties when the linear factor model is misspecified, either because of a missing factor or because ofa latent nonlinearity. Finally, least squares estimators of risk premia in the second step might be biased in finitesamples.19Thet-statistics after Shanken’s correction are−4.06 and−3.92, respectively.609Downloaded from by Queen Mary University of London useron 02 March 2018

Portfolios are formed based on rolling beta estimates. In Panel A, we reportresults for the market and the correlation risk factor (Model 1). In Panel B, we report results for the BKT eight-factor model (Model 2). The estimation methods are GLS and WLS versions of the (Fama-MacBeth) two-passregression methodology.t-statistics are in brackets.t-statistics in Columns 4 to 5 are calculated using standarderrors based on Shanken (1992) errors-in-variables (EIV) adjustment. The cross-sectional regressions are basedon 75 portfolios (based on a sort using the market betas). Each year from January 1999 to 2011 funds are sortedinto these portfolios based on their betas calculated using the previous 36 monthly returns. The sample period is
