We revisit in this note the macroeconomic impact of the recent rise in trade policy uncertainty. As in the literature, we do find that high trade policy uncertainty can adversely impact domestic and foreign economic activity. In addition, we identify an alternative business sentiment channel...

We develop a method to identify the most important predictors of long-term asset returns and use it to analyze the impact of model uncertainty on long-term investors. We find that the impact of model uncertainty changes a lot over time which leads to considerable time-variation in all moments of...

We study the effects of financial uncertainty on investment dynamics in the U.S. using a vector autoregression with drifting parameters and stochastic volatilities. We find time-varying negative effects of financial uncertainty shocks on investment. These effects have declined in the post-WWII...

We show that macroeconomic uncertainty can be considered as exogenous when assessing its effects on the U.S. economy. Instead, financial uncertainty can at least in part arise as an endogenous response to some macroeconomic developments, and overlooking this channel leads to distortions in the...

We investigate the link between macroeconomic uncertainty and business cycle asymmetry of the U.S. economy. To this end, we propose an unobserved component model in which the shocks are asymmetrically distributed, and the degree of asymmetry varies with macroeconomic uncertainty. An efficient...

Deriving an optimal asset allocation for institutional investors hinges crucially on the quality of inputs used in the optimization. If the mean vector and the covariance matrix are known with certainty, the classical mean-variance optimization of Markowitz (1952) produces optimal portfolios....
