The paper proves the existence of equilibrium in nonrenewable resource markets when extraction costs are non-convex and resource storage is possible. Inventories flatten the consumption path and eliminate price jumps at the end of the extraction period. Market equilibrium becomes then possible,...

This chapter surveys heterogeneous agent models with rational expectations that deliver a finite number of heterogeneous agents as an equilibrium outcomes. Instead of having a distribution with infinite support to follow, this class of models endogenously generates a finite number of agents as...
