setting, an increase in uncertainty about future shocks causes significant contractions in the economy and may lead to non … outcomes. Fluctuations in uncertainty and the zero lower bound help our model match the unconditional and stochastic volatility …

This paper discusses the nature of the uncertainty faced by central banks and considers three approaches to dealing … with uncertainty(1) formal optimization models and robust rules based on such models; (2) informal rules like the Taylor …

In this research, we provide new empirical evidence on the importance of time-varying uncertainty for the exchange rate … and the excess return in currency markets. Following an increase in monetary policy uncertainty, the dollar exchange rate … general-equilibrium theory of exchange rate determination based on the interaction between monetary policy and time …

, arises because these models load all uncertainty onto the supply side of the economy. We propose a simple theory of asset … pricing in which demand shocks play a central role. These shocks give rise to valuation risk that allows the model to account …

We study the design of optimal monetary policy under uncertainty in a dynamic stochastic general equilibrium models. We … use a Markov jump-linear-quadratic (MJLQ) approach to study policy design, approximating the uncertainty by different … a benchmark New Keynesian model, analyzing how policy is affected by uncertainty, and how learning and active …

dividend yield is typically viewed as a reflection of either changing risk, related to the business cycle, or irrational … risk as well as expected return, we develop Bayesian methods to examine the interaction between the data and an investor … and a riskless asset. In general, however, the simple risk/return model of Merton (1980) explains very little of the yield …

unconditional cross-sectional moments of household consumption growth and the moments of the risk-free rate, equity premium, price …-dividend ratio, and aggregate dividend and consumption growth. The model-implied risk-free rate and price-dividend ratio are … procyclical while the market return has countercyclical mean and variance. Finally, household consumption risk explains the cross …

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 …
