Differences in expected returns reflect and guide investment decisions in the economy. Thus, one often wants to explain differences in expected return without assuming a specific model of the economy. We propose two tests to assess whether risk alone can explain differences in expected returns.

We provide the tests with equilibrium foundations that hold within a large class of models. We study tests' properties mathematically and in simulations. Empirically, we find that risk cannot explain most differences in expected returns of characteristic-sorted portfolios. Our findings are consistent with a prominent role of frictions and behavioral biases.
