We develop a finite-sample procedure to test for mean-variance efficiency and spanning without imposing any parametric assumptions on the distribution of model disturbances. In so doing, we provide an exact distribution-free method to test uniform linear restrictions in multivariate linear...

Sellers of variance swaps earn time-varying risk premia for their exposure to realized variance, the level of variance swap rates, and the slope of the variance swap curve. To measure risk premia, we estimate a dynamic term structure model that decomposes variance swap rates into expected...

This paper studies whether sentiment is rewarded with a significant risk premium on the European stock markets. We examine several sentiment proxies and identify the Economic Sentiment Indicator (ESI) from the EU Commission as the most relevant sentiment proxy for our sample. The analysis is...
