associated with average returns. We show that the resulting portfolios are likely to capture not only the priced risk associated … with the characteristic, but also unpriced risk. We develop a procedure to remove this unpriced risk using covariance …

We study the role of information in asset pricing models with long-run cash flow risk. When investors can distinguish … short- from long-run consumption risks (full information), the model generates a sizable equity risk premium only if the … propose a sparsity-based bounded rationality model of long-run risk that is both parsimonious and fully identified from …

economy tends to damage risk sharing when the composition of collateral is biased toward private assets. As we show that a … stable economy is more propitious to the creation of private collateral, stability makes risk sharing increasingly fragile to … risk sharing to aggregate volatility as predicted by our model …

In Merton (1987), idiosyncratic risk is priced in equilibrium as a consequence of incomplete diversification. We modify … results in a state-dependent idiosyncratic risk premium that is higher when average idiosyncratic volatility is low, and vice … versa. The data appear to be consistent with a positive state-dependent premium for idiosyncratic risk both in the US and in …

We investigate the relationship between uncertainty about monetary policy and its transmission mechanism, and economic …-order effect on their dynamics. The data favors a model with two unspanned volatility factors that capture uncertainty about … monetary policy and the term premium. Uncertainty contributes negatively to economic activity. Two dimensions of uncertainty …

We study the effects of changes in uncertainty about future fiscal policy on aggregate economic activity. Fiscal … consolidation inevitable, there is considerable uncertainty about the policy mix and timing of such budgetary adjustment. To … evaluate the consequences of this increased uncertainty, we first estimate tax and spending processes for the U.S. that allow …
