We propose a two-stage procedure to estimate conditional beta pricing models that allows for flexibility in the dynamics of asset betas and market prices of risk (MPR). First, conditional betas are estimated nonparametrically for each asset and period using the time-series of previous data....

This paper proposes the mixed frequency conditional beta. We employ the MIDAS framework to decompose market betas into high and low frequency components. The total mixed frequency beta is the weighted average of these two components. Then, we analyze the macroeconomic determinants of stock...
