We provide a measure of sparsity for expected returns within the context of classical factor models. Our measure is inversely related to the percentage of active predictors. Empirically, sparsity varies over time and displays an apparent countercyclical behavior. Proxies for financial conditions...

A recent literature has shown that REIT returns contain strong evidence of bull and bear dynamic regimes that may be best captured using nonlinear econometric models of the Markov switching type. In fact, REIT returns would display regime shifts that are more abrupt and persistent than in the...

We classify asset pricing anomalies into those that exacerbate mispricing (build-up anomalies) and those that resolve it (resolution anomalies). To this end, we estimate the dynamics of price wedges for a large number of well-known anomaly portfolios in the factor zoo and map them to firm-level...

We decompose the time-variation in returns on anomaly portfolios into the effects of different investor types and their trading motives. Trading due to changes in investor preferences for observed stock characteristics explains nearly 50% of the variation, while the effects of changes in stock...

We show that a business-cycle component of consumption growth (dubbed business-cycle consumption) with cycles between 2 and 4 years is effective in explaining the differences in risk premia across alternative test assets, including recently-proposed anomaly portfolios. We formalize the mapping...
