This paper establishes a new empirical fact: Mutual funds' flow-performance sensitivity is a hump-shaped function of aggregate risk-factor realizations. Explanations based on extant theories can explain only a fraction of the pattern. We thus develop a new parsimonious model. It assumes Bayesian investors who are uncertain about the degree to which fund returns are exposed to systematic risk. Fund performance is then less informative about manager skill when factor realizations are larger in absolute value. The data also support the out-of-sample prediction that the hump shape is more pronounced for funds with more uncertain risk loadings.

Firms until recently were effectively constrained to hold liquid assets in non-interest-bearing accounts. As a result, the cost of capital of firms' liquid-assets portfolios exceeded the return, especially when the risk-free interest rate was high. The spread between cost and return is the cost of carry. Changes in the cost of carry explain the dynamics of corporate "cash" holdings both in the United States and abroad, and the level of cost of carry explains the level of liquid-asset holdings across countries. We conclude that current US corporate cash holdings are not abnormal in a historical or international comparison.

When Bayesian risk-averse investors are uncertain about their assets’ cash flows’ exposure to systematic risk, stock prices react to news more in downturns than in upturns, implying higher volatility in downturns and negatively skewed returns. In good times, less desirable assets with low average cash flows and high market risk perform similar to more desirable assets with high average cash flows and low market risk, rendering them difficult to distinguish. However, their performance diverges in downturns, enabling better inference. Consistent with these predictions, stocks’ reaction to earnings news is up to 70% stronger in downturns than in upturns.

Inspired by experimental evidence, we amend the recursive utility model to let risk aversion decrease with the temporal horizon. Our pseudo-recursive preferences remain tractable and retain appealing features of the long-run risk framework, notably its success at explaining asset pricing moments. In addition, our model addresses two challenges to the standard model. Calibrating the agents’ preferences to explain the equity premium no longer implies an extreme preference for early resolutions of uncertainty. Horizon-dependent risk aversion helps resolve key puzzles in finance on the valuation of assets across maturities and captures the term structure of equity risk premiums and its dynamics.
