This paper studies how updating affects ambiguity-attitude. In particular we focus on the generalized Bayesian update of the Jaffray-Phillipe sub-class of Choquet Expected Utility preferences. We find conditions for ambiguity-attitude to be the same before and after updating. A necessary and...

Beliefs are a central determinant of behavior. Recent models assume that beliefs about or the anticipation of future consumption have direct utility consequences. This gives rise to informational preferences, i.e., preferences over the timing and structure of information. Using a novel and...

We consider the aggregation of individual agents' von Neumann-Morgenstern preferences over lotteries into a social planner's von Neumann-Morgenstern preference. We start from Harsanyi's axiomatization of utilitarianism, and ask under which conditions a social preference order that satisfies...

We develop a theoretical framework to explain firms' offshoring decisions in the presence of uncertainty. This model highlights the role of labor market institutions in shaping a firm's ability to effectively react upon future shocks, yielding a sharp prediction of the prevalence of offshoring...

The paper studies the interaction between cyclical uncertainty and investment in a stochastic real option framework where demand shifts stochastically between three different states, each with different rates of drift and volatility. In our setting the shifts are governed by a three-state Markov...

This paper examines the impact of Knightian uncertainty upon optimal climate policy through the prism of a continuous-time real option modelling framework. We analytically determine optimal intertemporal climate policies under ambiguity. Additionally, numerical simulations are provided to...

Global climate change and other environmental challenges require the development of new energy technologies with lower emissions. In the near-term, R&D investments, either by government or the private sector, can bring down the costs of these lower emission technologies. However, the results of...

The paper examines the monetary-fiscal interactions in a monetary union model with uncertainty due to imperfect central bank transparency. We first show that monetary uncertainty disciplines fiscal policymakers and thereby reduces taxes, average inflation and output distortions. However, as more...
