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...

We introduce "lack-of-recall" of past transactions as an alternative assumption to anonymity in a model where trade is centralized. In environments where there is an intertemporal lack-of-double-coincidence of wants problem and lack-of-commitment, lack-of-recall can give rise to monetary...

Decision theory postulates that human subjects have a well-defined “ranking” over different values of an attribute, irrespective of whether an observer is extracting information about this ranking. We study a sequence of “double-slit” experiments designed to perform repeated measurements...

The authors study the design of efficient intertemporal payment arrangements when the ability of agents to perform certain welfare-improving transactions is subject to random and unobservable shocks. Efficiency is achieved via a payment system that assigns balances to participants, adjusts them...

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...
