The authors study a Markov equilibrium for the case where a monopolist extracts a nonrenewable resource which is converted to a durable good, which then depreciates at a constant rate. They show that, in a stationary, continuous time model (infinite horizon, infinitesimal period of commitment),...

Apple’s original decision to market iPhones using a single downstream vendor prompted calls for mandatory universal distribution (MUD), whereby all downstream vendors would sell the iPhone under the same contract terms. The upstream monopoly may want eitherone or more downstream vendors,...

The tendency to foreshorten time units as we peer further into the future provides an explanation for hyperbolic discounting at an intergenerational time scale. We study implications of hyperbolic discounting for climate change policy, when the probability of a climate-induced catastrophe...
