We develop a dynamic general equilibrium integrated assessment model thatincorporates costs due to new technology adoption in renewable energy as wellas externalities associated with carbon emissions and renewable technologyspillovers. We use world economy data to calibrate our model and...

We study the effect of technological progress on the optimal transition to a renewable energy-fueled world economy. We develop a dynamic general equilibrium model where energy is used as an input in production and can come from fossil or renewable sources. Both require the use of capital, which...

The authors study credible information transmission by a benevolent short-lived central bank. They consider two possibilities: direct revelation through an announcement, versus indirect information transmission through monetary policy. These two ways of transmitting information have very...

We study credible information transmission by a benevolent Central Bank. We consider two possibilities: direct revelation through an announcement, versus indirect information transmission through monetary policy. These two ways of transmitting information have very different consequences. Since...

We study a dynamic stochastic general equilibrium model where agents are concerned about model uncertainty regarding climate change. An externality from greenhouse gas emissions adversely affects the economy's capital stock. We assume that the mapping from climate change to damages is subject to...

We study credible information transmission by a benevolent short-lived central bank. We consider two possibilities: direct revelation through an announcement, versus indirect transmission through monetary policy. We show that, in the presence of externalities creating a wedge between private and...

Emissions trading mechanisms have been proposed, and in some cases implemented, as a tool to reduce pollution. We explore the similarities between emission-trading mechanisms and monetary mechanisms. Both attempt to implement desirable allocations under various frictions, including risk and...

We study a dynamic stochastic general equilibrium model in which agents are concerned about model uncertainty regarding climate change. An externality from greenhouse gas emissions damages the economy's capital stock. We assume that the mapping from climate change to damages is subject to...

I study equilibrium selection by an evolutionary process in an environment with multiple equilibria, one of which involves a banking panic. The analysis is built on a repeated version of the Diamond-Dybvig (1983) model. The optimal (run free) equilibrium is uniquely selected if it is also "risk...

We provide a model of the experimental process in the social sciences by adapting the symbolism developed for modeling experiments in atomic physics. Meaningful measurements are represented by operators that obey a non-commutative algebra. Thus, the order in which the experimenter attempts to...
