We present a simple 2-factor model that helps explain several capital asset pricing model (CAPM) anomalies (value premium, return reversal, equity duration, asset growth, and inventory growth). The model is consistent with Merton’s intertemporal CAPM (ICAPM) framework, and the key risk factor is the innovation on a short-term interest rate, the federal funds rate, or the T-bill rate. This model explains a large fraction of the dispersion in the average returns of the joint market anomalies. Moreover, the model compares favorably with alternative multifactor models widely used in the literature. Hence, short-term interest rates seem to be relevant for explaining several dimensions of cross-sectional equity risk premia.
