On aggregation bias in fixed-event forecast efficiency tests

Author

  • Isiklar, Gultekin

Abstract

This note shows that problems due to aggregation in fixed-event forecast efficiency tests are not as severe as they are in unbiasedness tests. We also show that first lags of consensus revisions should be avoided in the tests.
