		| I introduce an econometric framework to identify and estimate horizon-based heterogeneity in panel data. Using this approach, I identify the horizon-based structure in the cross section of portfolio returns. Accounting for this structure results in a significant improvement in pricing accuracy relative to the standard CAPM and Fama-French three-factor models. The majority of the improvement arises from separately pricing long-horizon and shorter-horizon market exposure. |
