Inflation-targeting central banks have only imperfect knowledge about the effect of policy decisions on inflation. An important source of uncertainty is the relationship between inflation and unemployment. This paper studies the optimal monetary policy in the presence of uncertainty about the...

We address the problem of choosing a portfolio of policies under "deep uncertainty." We introduce the idea of belief dominance as a way to derive a set of non-dominated portfolios and robust individual alternatives. Our approach departs from the tradition of providing a single recommended...

uncertainty into Integrated Assessment Models (IAMs). Uncertainty is transformed into a risk-premium, damage-correction, region …. This risk premium quantifies what society would be willing to pay to insure against the uncertainty of the damages, and it … highly sensitive to the coefficient of relative risk aversion. Once the climate change damage function incorporates the risk …

We present a model in which investors observe the same macroeconomic data but have varying levels of information about the parameters that determine the distribution of the expected returns on investment. During a crisis that increases macroeconomic uncertainty and reduces asset prices, the...

Economic modeling assumes, for the most part, that agents are Bayesian, that is, that they entertain probabilistic beliefs, objective or subjective, regarding any event in question. We argue that the formation of such beliefs calls for a deeper examination and for explicit modeling. Models of...

In this paper we present a dynamic discrete-time model that allows to investigate the impact of risk-aversion in an …-time limit of our model with no uncertainty and no risk-aversion. Focusing on the continuous-time limit of the infinite horizon … inversely related to the degrees of uncertainty and risk-aversion. However, the effect of uncertainty and risk …
