Measuring “Dark Matter” in Asset Pricing Models
Published: 03/03/2024 | DOI: 10.1111/jofi.13317
HUI CHEN, WINSTON WEI DOU, LEONID KOGAN
We formalize the concept of “dark matter” in asset pricing models by quantifying the additional informativeness of cross‐equation restrictions about fundamental dynamics. The dark‐matter measure captures the degree of fragility for models that are potentially misspecified and unstable: a large dark‐matter measure indicates that the model lacks internal refutability (weak power of optimal specification tests) and external validity (high overfitting tendency and poor out‐of‐sample fit). The measure can be computed at low cost even for complex dynamic structural models. To illustrate its applications, we provide quantitative examples applying the measure to (time‐varying) rare‐disaster risk and long‐run risk models.
Inalienable Customer Capital, Corporate Liquidity, and Stock Returns
Published: 07/10/2020 | DOI: 10.1111/jofi.12960

We develop a model in which customer capital depends on key talents' contribution and pure brand recognition. Customer capital guarantees stable demand but is fragile to financial constraints risk if retained mainly by talents, who tend to quit financially constrained firms, damaging customer capital. Using a proprietary, granular brand‐perception survey, we construct a firm‐level measure of the inalienability of customer capital (ICC) that captures the degree to which customer capital depends on talents. Firms with higher ICC have higher average returns, higher talent turnover, and more precautionary financial policies. The ICC‐sorted long‐short portfolio's spread comoves with financial constraints factor.
