We study a model of social learning in networks where the dynamics of beliefs are driven by conversations of dissonance-minimizing agents. Given their current beliefs, agents make statements, tune them to the statements of their associates, and then revise their beliefs. We characterize the...

We study the role of expectations of naive agents in a general equilibrium version of the Ramsey model with quasi-hyperbolic discounting. When agents recognize others’ naivete, as strongly suggested by empirical evidence, they revise consumption paths, correctly anticipating prices in a...

We consider a neoclassical growth model with quasi-hyperbolic discounting under Kantian optimization: each temporal self acts in a way that they would like every future self to act. We introduce the notion of a Kantian policy as an outcome of Kantian optimization in a given class of policies. We...

In this paper, we propose an approach to describe the behavior of naive agents with quasi-hyperbolic discounting in the neoclassical growth model. To study time-inconsistent decision making of an agent who cannot commit to future actions, we introduce the notion of sliding equilibrium and dis-...

We derive the optimal contributions to global climate policy when countries differ with respect to income level and pollution intensity. Countries growth rates are determined endogenously, and abatement efficiency is improved by technical progress. We show that country heterogeneity has a...
